Construct a triangle that has one angle measuring 30 deg and another measuring 110°. How many possible triangles can you draw?

Answers

There is only one possible triangle that can be drawn with one angle measuring 30 deg and another measuring 110°. This is because all triangles have a sum of 180° for the three angles.

What is triangle ?

Triangle is a three-sided polygon with three straight sides that intersect at three vertices. It is one of the basic shapes in geometry, and is considered to be a building block of other shapes. Triangles can be classified according to their sides, angles, and area. The most common types of triangles are equilateral, isosceles, and scalene triangles, which are classified according to the length of their sides. Triangles can also be classified according to their angles, as acute, right, and obtuse triangles, which are classified according to the size of their angles. Additionally, the area of a triangle is determined by its base, height, and side lengths.

Therefore if one angle is 30° and the other is 110°, the third angle must be 40° for the triangle to be valid.

What is angle?

An angle is a geometrical figure that is formed by two lines or rays that have a common endpoint. It is a measure of the amount of turn between the two lines or rays. Angles are typically measured in degrees, with a full angle measuring 360 degrees. Angles can also be measured in radians, with a full angle measuring 2π radians. Angles are used in math and science to describe position and orientation. Common examples of angles include right angles, acute angles, obtuse angles, and straight angles.

Answer: 3/5 as a decimal is 0.6

Answer: 3/5 as a decimal is 0.6Let us see how to convert 3/5 to a decimal using two methods.

Answer: 3/5 as a decimal is 0.6Let us see how to convert 3/5 to a decimal using two methods.Explanation

Answer: 3/5 as a decimal is 0.6Let us see how to convert 3/5 to a decimal using two methods.ExplanationMethod 1: How to write 3/5 as a decimal using the division method?

Step 1: To convert any fraction to decimal form, we just need to divide its numerator by denominator.

Step 2: Here, the fraction is 3/5 which means we need to perform 3 ÷ 5

Step 3: This gives the answer as 0.6. So, 3/5 as a decimal is 0.6

Method 2: How to write 3/5 as a decimal by converting the denominator to powers of 10?

Step 1: Find a number that we can multiply by the denominator of the fraction to make it 10 or 100 or 1000 and so on. In this case, if we multiply the denominator by 2 it becomes 10. Therefore, we will multiply both the numerator and the denominator by 2 which will make it 3/5 = (3 × 2) / (5 × 2) = 6/10

Step 2: After multiplying both numerator and denominator by that number, we have converted it into its equivalent fraction.

Step 3: Then, we write down just the numerator by putting the decimal point in the correct place, that is, one space to the left starting from the right-hand side for every zero in the denominator. This means 6/10 = 0.6

Step 3: Then, we write down just the numerator by putting the decimal point in the correct place, that is, one space to the left starting from the right-hand side for every zero in the denominator. This means 6/10 = 0.6Irrespective of the methods used, the answer to 3/5 as a decimal number will always remain the same. Therefore, now we know what is 3/5 in decimal form.

Step 3: Then, we write down just the numerator by putting the decimal point in the correct place, that is, one space to the left starting from the right-hand side for every zero in the denominator. This means 6/10 = 0.6Irrespective of the methods used, the answer to 3/5 as a decimal number will always remain the same. Therefore, now we know what is 3/5 in decimal form.Thus, 3/5 as a decimal is 0.6

Answers

Answer:

Let x = the cost of a movieLet y = the cost of a gameUsing these variables,

we can set up equations.3x + 5y = 42 eq19x + 7y = 72 eq2

We have here a system of equations, where we have two or more equations with two or more different variables.

We use the elimination method to solve for the variables.

Multiply eq1 by 3. Keep eq2.

9x + 15y = 126 eq1

9x + 7y = 72 eq2

Subtract eq2 from eq1 to eliminate the x terms.

8y = 54y  

= 6.75

This rental cost of one video game is $6.75

Substitute the value of y into eq1 to solve for x.

This will give you the rental cost of one movie.

Answers

The fourth equation which is tan x = [tex]\frac{7000}{5000}[/tex] is the correct way to calculate x. This has been obtained by using trigonometry.

What is trigonometry?

Trigonometry is the study of right-angled triangles, which includes the sides, angles, and connections of each triangle.

We are given that the airplane is 5,000 ft above ground and has to land on a runway that is 7,000 ft away with an angle x.

Since, we are not given the hypotenuse so, we will use tan θ.

We know that in trigonometry, tan θ is calculated as the ratio of the opposite side to the adjacent side.

So,

tan x = [tex]\frac{7000}{5000}[/tex]

Hence, the fourth equation is the correct answer.

Answers

The volume of Laura's gold ring is 21.6 cubic centimeters.

To find the volume of the gold ring, we need to determine the volume of water that is displaced when the ring is dropped into the glass.

The initial volume of water in the glass can be calculated as the product of the base area and the height of the water:

V1 = base area x height of water = 7 cm x 4.5 cm x 8.8 cm = 277.2 cm³

When the gold ring is dropped into the glass, it displaces some of the water, causing the water level to rise. The new volume of water in the glass can be calculated using the same formula, but with the new height of the water:

V2 = base area x height of water with ring = 7 cm x 4.5 cm x 9.2 cm = 298.8 cm³

The volume of the gold ring can be calculated by subtracting the initial volume of water (before the ring was added) from the new volume of water (after the ring was added):

Volume of gold ring = V2 - V1 = 298.8 cm³ - 277.2 cm³ = 21.6 cm³

a cable tv receiving dish is in the shape of a paraboloid of revolution. find the location of the receiver, which is placed at the focus, if the dish is 6 feet across at its opening and 2 feet deep.

Answers

the receiver is located at (0, 0, 2.25 feet) or (0, 0, 27 inches).To find the location of the receiver, we first need to determine the equation of the paraboloid.

The standard equation for a paraboloid of revolution with a vertical axis is:

z = [tex](x^2 + y^2)[/tex]/(4f)

Where:

z is the height at any point (x, y) on the paraboloid.

x and y are the horizontal coordinates of the point.

f is the focal length of the paraboloid, which is half the depth of the dish.

In this case, the dish is 6 feet across at its opening, so the diameter is 6 feet and the radius is 3 feet. Therefore, the maximum value of x and y is 3 feet. The depth of the dish is given as 2 feet.

Using these values, we can solve for the focal length:

2 = [tex](3^2 + 3^2)[/tex]/(4f)

2 = 18/(4f)

f = 18/8 = 9/4 = 2.25 feet

Now that we have the value of f, we can find the location of the receiver, which is placed at the focus of the paraboloid. The focus is located at (0, 0, f).

Therefore, the receiver is located at (0, 0, 2.25 feet) or (0, 0, 27 inches).

Answers

There are 35 different 3-digit numbers that can be formed using the digits 0, 1, 2, 3, 4, 5, 6, if the repetition of digits is not allowed.

What is probability?

Probability is a branch of mathematics that deals with the study of randomness and uncertainty in events. It is the measure of the likelihood or chance that an event will occur. Probability is expressed as a number between 0 and 1, where 0 indicates that the event will not occur and 1 indicates that the event will occur with certainty.

According to the given information :

To form a 3-digit number using the given set of 7 digits (0, 1, 2, 3, 4, 5, 6) without repetition, we need to choose 3 different digits from the set.

We can count the number of ways to select 3 distinct digits from the set of 7 using the combination formula, which is:

C(n, k) = n! / (k! * (n-k)!)

Where n is the total number of items in the set, and k is the number of items we want to choose.

In this case, n = 7 (because we have 7 digits to choose from), and k = 3 (because we want to choose 3 digits to form a 3-digit number).

Therefore, the number of ways to select 3 distinct digits from the set of 7 is:

C(7, 3) = 7! / (3! * 4!)

= (7 * 6 * 5 * 4 * 3 * 2 * 1) / ((3 * 2 * 1) * (4 * 3 * 2 * 1))

= (7 * 6 * 5) / (3 * 2 * 1)

= 35

From Point 1 to Point 2 on the trail, the bike rider is traveling uphill, which means that the change in kinetic energy is negative because the rider is slowing down due to the work required to move against gravity. The rider is losing kinetic energy and converting it into potential energy.

On the other hand, the change in potential energy from Point 1 to Point 2 is positive because the rider is gaining height and storing potential energy due to the work done against gravity. As the rider climbs uphill, the potential energy of the rider-bike system increases.

So, to summarize:

Change in kinetic energy from Point 1 to Point 2: Negative

Change in potential energy from Point 1 to Point 2: Positive

write the number 150 as a sum of three numbers so that the sum of the products taken two at a time is a maximum. (enter the three numbers as a comma-separated list.)

Answers

The three numbers are 50, 50, and 50, which give a maximum sum of products taken two at a time of 5000.

To find the sum of three numbers whose product is maximum, we need to distribute the numbers as equally as possible. Therefore, we divide 150 by 3, giving 50. This means that the sum of the three numbers is 150, and their product is maximized.

To check that this is indeed the case, we can calculate the sum of the products taken two at a time: 50x50 + 50x50 + 50x50 = 5000, which is the maximum possible sum.

Therefore, the three numbers are 50, 50, and 50.

a bridge hand consists of 13 cards from a deck of 52. find the probability that a bridge hand includes exactly 4 aces and exactly 3 kings.

Answers

The probability that a bridge hand includes 4 acres and exactly 3 kings is 0.028%

To find the probability of getting exactly 4 aces and 3 kings in a bridge hand, we can use the following formula:

P(4 aces and 3 kings) = (number of ways to get 4 aces and 3 kings) / (number of ways to select 13 cards from a deck of 52)

To calculate the numerator, we can first find the number of ways to choose 4 aces from the 4 available in the deck, and then the number of ways to choose 3 kings from the 4 available in the deck. The remaining 6 cards can be any of the 44 non-ace, non-king cards. Therefore:

Number of ways to get 4 aces and 3 kings = (4 choose 4) x (4 choose 3) x (44 choose 6) = 1 x 4 x 44,380,776 = 177,523,104

To calculate the denominator, we can find the total number of ways to choose any 13 cards from the 52-card deck:

Number of ways to select 13 cards from a deck of 52 = (52 choose 13) = 635,013,559,600

Therefore, the probability of getting exactly 4 aces and 3 kings in a bridge hand is:

P(4 aces and 3 kings) = (number of ways to get 4 aces and 3 kings) / (number of ways to select 13 cards from a deck of 52) = 177,523,104 / 635,013,559,600 = 0.0002799 or approximately 0.028%.

jenny places a total of red easter eggs in several green baskets and a total of orange easter eggs in some blue baskets. each basket contains the same number of eggs and there are at least eggs in each basket. how many eggs did jenny put in each basket?

Answers

If each basket contains the same number of eggs and there are at least 4 eggs in each basket, Jenny put 3 red eggs in each of 6 baskets, and 4 orange eggs in each of 6 baskets.

Let's call the number of eggs in each basket "x." We know that Jenny placed a total of 18 red eggs, so the number of baskets with red eggs can be represented as 18/x. Similarly, the number of baskets with orange eggs can be represented as 24/x.

Since we know that each basket contains at least 4 eggs, we can set up the inequality 4 ≤ x.

Now we can use this information to set up an equation:

18/x + 24/x = total number of baskets

Simplifying this equation, we get:

42/x = total number of baskets

But we also know that the total number of baskets is an integer (you can't have a fraction of a basket), so x must be a factor of 42.

The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. But we also know that each basket must contain at least 4 eggs, so we can eliminate 1, 2, and 3 as possible values of x.

Therefore, the possible values of x are 6, 7, 14, 21, and 42. But we also know that there are 18 red eggs and 24 orange eggs, so x must be a factor of both 18 and 24.

The common factors of 18 and 24 are 1, 2, 3, and 6. Therefore, the only possible value of x is 6.

f(x) + 3 = 4 - x² + 3

= 7 - x²

So the equation of the red graph is:

g(x) = 7 - x²

Therefore, the correct answer is option C: g(x) = 7 - x².

Answers

The exponential function that shows the relationship between the city's population y and the number of years t since the start of the study is [tex]y = 390000 * (1.073)^t[/tex]

Population tends to change with time. It might increase or decrease. Let y be the city's population after t years since the start of the study, and let [tex]Po[/tex] be the initial population at the start of the study. We can use the formula for exponential growth to represent the relationship between y and t:

Final population = Initial population x (growth rate)^years

[tex]y = Po*(1+0.073)^t[/tex]

[tex]y = Po* (1.073)^{(t)[/tex]

Substituting the values in the above equation we get the following equation:

[tex]y = 390,000*(1.073)^t[/tex]

The above function when represented in exponential form will be equal to [tex]y=390,000*(e)^{(0.073t)[/tex]

which distribution is described by predicting the number of girls amoung 5 children randomly selected from a group of 10 girls and 10 boys

Answers

The distribution described is a binomial distribution.

A binomial distribution describes a discrete probability distribution, which means the values are countable. This distribution has two possible outcomes, in this case, either a girl or a boy. The probability of getting a girl is 0.5, as there are 10 girls and 10 boys in the group.

The binomial distribution is described by the following formula: P(x) = nCx * p^x * (1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success in each trial.

In this case, n=5, x= number of girls, and p=0.5. Thus, P(x)= 5Cx * 0.5^x * 0.5^5-x. To predict the number of girls among 5 randomly selected children from the group, we need to calculate P(x) for x=0,1,2,3,4, and 5. This will give us the probabilities of selecting 0, 1, 2, 3, 4, and 5 girls in the group.

The sum of all these probabilities should be equal to 1, indicating that all the possibilities have been accounted for. This binomial distribution will help us predict the number of girls among 5 randomly selected children from the group of 10 girls and 10 boys.

there is a group of five children, where two of the children are twins. in how many ways can i distribute $8$ identical pieces of candy to the children, if the twins must get an equal amount of candy?

Answers

There are 1960 different ways to distribute 8 identical pieces of candy to the five children, where the twins get an equal amount of candy.

First, distribute the candy to the twins.

Split the 8 pieces of candy into two equal parts for the twins using combinations:

C(8, 4)

This means selecting 4 pieces of candy from the 8 identical pieces for one twin, and the remaining 4 pieces will automatically go to the other twin.

C(8, 4) is calculated as:

[tex]^8C_4 = \dfrac{8!}{4!(8-4)!}[/tex]

     = 8! / (4! * 4!)

     = (8 * 7 * 6 * 5) / (4 * 3 * 2 * 1)

     = 70

Now, you have distributed 4 pieces of candy to each of the twins. Y

In this case, you have 6 pieces of candy to distribute among 3 children, and you can use two dividers (bars) to separate the candy for each child.

This can be represented as:

OO|OO|OO

The two bars split the 6 pieces of candy into three sections for the three children.

So, you have C(6 + 2, 2) ways to distribute the remaining candy:

[tex]^{6+2}C_2 = \dfrac{8!}{2!(8-2)!}[/tex]

         = 8! / (2!(8 - 2)!)

         = 8! / (2! * 6!)

         = (8 * 7) / (2 * 1)

         = 28

Now, the total number of ways to distribute the candy

Total ways = C(8, 4) * C(8, 2) = 70 * 28 = 1960

So, there are 1960 different ways to distribute.

a measurement of the diameter of a disk has an uncertainty of 1.4 mm. how many measurements must be made so that the diameter can be estimated with an uncertainty of only 0.5 mm? round the answer to the next largest integer.

Answers

Number of measurements that must be made so that the diameter can be estimated with an uncertainty of only 0.5 mm is 16

To estimate the diameter with an uncertainty of 0.5 mm, we need to reduce the uncertainty to that level. Let's call the number of measurements we need to make "N". We can use the formula for the standard deviation of the mean

σ_mean = σ / sqrt(N)

where σ is the standard deviation of the individual measurements. In this case, the uncertainty of each measurement is given as 1.4 mm, which we can assume is the standard deviation.

To reduce the uncertainty to 0.5 mm, we need

0.5 = 1.4 / sqrt(N)

Solving for N, we get

N = (1.4 / 0.5)^2 = 15.68

≈ 16

a children's liquid medicine contains 100 mg of the active ingredient in 5 ml . if a child should receive 300 mg of the active ingredient, how many milliliters of the medicine should the child be given? for the purposes of this question, assume that these numbers are exact.

Answers

The child should be given 15 ml of the medicine to receive 300 mg of the active ingredient.

The given problem requires us to determine the number of milliliters of a liquid medicine that a child should receive in order to obtain a specific dosage of the active ingredient. We are given that the medicine contains 100 mg of the active ingredient in 5 ml.

The child needs to receive 300 mg of the active ingredient, and there are 100 mg of the active ingredient in 5 ml of the medicine. Therefore, the child should be given:

[tex]\frac{300 mg}{100mg/5ml} = \frac{300\text{ mg} \times 5\text{ ml}}{100\text{ mg}} = 15\text{ ml}$$[/tex]

So the child should be given 15 ml of the medicine to receive 300 mg of the active ingredient.

Which of the following correctly describes the domain of the function shown below?

Answers

Except than x = 1, all real numbers fall within the function's domain.

Why can't a domain consist entirely of real numbers?

Since there are no limitations on what we can substitute for x, the domain of a function, f(x), is all real numbers because any real numbers would make f(x) a defined function. As a result, when this is not the case, the domain of a function, f(x), is not all real numbers.

The rational function r(x) = 2x/(x-1) is defined as follows.

So, we set the denominator to zero and solve for x in order to determine the domain of r(x):

x - 1 = 0

x = 1

Hence, x = 1 is the only value of x that causes the denominator to equal 0. R(x) therefore has a domain of all real numbers other than x = 1.

We can express the domain as follows in interval notation:

(-∞, 1) U (1, ∞)

Except than x = 1, all real numbers fall within the function's domain.

find the distance, d, of ab a=(2,-3) b=(4,5)

Answers

The distance D between points A and B is approximately 8.25 units.

What is the distance between the given pair of points?

The distance formula used in finding the distance between two points is expressed as;

D = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² )

Where (x1, y1) and (x2, y2) are the coordinates of the two points.

Using the given points, we have:

a = (2, -3)

b = (4, 5)

We have:

D = √( ( 4 - 2 )² + ( 5 - (-3) )² )

D = √( ( 2 )² + ( 5 + 3 )² )

D = √( 2² + 8² )

D = √( 4 + 64 )

D = √68

D = 8.25

Therefore, the distance is 8.25 units.
