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

william can mulch a garden in 20 minutes. together, william and tina can mulch the same garden in 11 minutes. how long will it take tina to mulch the garden when working alone?

Answers

Tina can mulch the garden alone in 25 minutes.

Let's use the formula for the work rate to solve the problem. If William can mulch the garden alone in 20 minutes, his work rate is 1/20. Similarly, let's assume that Tina can mulch the garden alone in x minutes, so her work rate is 1/x.

When they work together, their work rates add up, so we have:

1/20 + 1/x = 1/11

Now we can solve for x:

1/x = 1/11 - 1/20

1/x = (20 - 11) / (11 x 20)

1/x = 9 / 220

x = 220 / 9

x ≈ 24.4

So it would take Tina 24.4 minutes to mulch the garden alone.

However, we need to round this up to the nearest minute because you can't have a fraction of a minute. Therefore, Tina can mulch the garden alone in 25 minutes.

Alternatively, we can use the inverse formula for the work rate to solve for Tina's time alone:

1/20 + 1/t = 1/11

1/t = 1/11 - 1/20

1/t = (20 - 11) / (11 x 20)

1/t = 9 / 220

t = 220 / 9

t ≈ 24.4

So Tina can mulch the garden alone in 24.4 minutes, which rounds up to 25 minutes.

what is percentile ?

In statistics, a percentile is a metric that is used to express where one observation stands in relation to a larger group of data. It displays the proportion of data points that fall under a given value. For instance, if a student achieves a score in the 90th percentile on a standardised test, it signifies that they outperformed 90% of their peers who also took the test. As an alternative, if a child is taller than 25% of children their age and shorter than 75%, their height is in the 25th percentile for their age.

given

We must first compute the z-score using the following formula to determine the percentile of the child's reading proficiency.

z = (x - μ) / σ

where x represents the child's reading rate, represents the grade-level mean reading rate, and represents the standard deviation.

Inputting the values provided yields:

z = (46.2 - 85) / 22

z = -1.727

We can calculate or use a conventional normal distribution table to obtain the value of 0.0428 for the region to the left of z = -1.727. The child's reading rate is at the 4.28th percentile according to this statistic.

As a result, the child's reading proficiency is 4.3 percentile (rounded to one decimal place).

By charging $11 per square yard as opposed to $12 per square yard at Shop A, Store B offers the carpet for a lower price per square yard.

What distinguishes a table from a graph?

The same data that is displayed in tables is also presented in charts and graphs. Yet, compared to a table, a chart or graph provides less detail or greater imprecision.

We must divide the total cost by the quantity of carpet square yards in order to determine the price per square yard. Seeing from the table that Shop A charges $360 for 30 square yards of carpet, the following information is provided:

Shop A's price per square yard is $360.30 sq yard divided by $12 per sq yd

A similar price of $550 is charged by Store B for 50 square yards of carpet, giving us:

$550 divided by 50 square yards yields $11 per square yard at store B.

the park service is considering offering a discount for the 5% of their patrons who spend the least time at the hot springs. what is the longest amount of time a patron can spend at the hot springs and still receive the discount? minutes.

Answers

The longest amount of time a patron can spend at the hot springs and still receive the discount is approximately 43.55 minutes.

To determine the longest amount of time a patron can spend at the hot springs and still receive the discount, we need to find the 5th percentile of the time spent by all patrons.

Let's say we have a sample of 1000 patrons and their time spent at the hot springs is normally distributed with a mean of 60 minutes and a standard deviation of 10 minutes. We can use the z-score formula to find the value corresponding to the 5th percentile:

[tex]$z = \frac{x - \mu}{\sigma}$[/tex]

where x is the value at the 5th percentile, [tex]$\mu$[/tex] is the mean, [tex]$\sigma$[/tex] is the standard deviation, and z is the z-score corresponding to the 5th percentile.

Since we want to find the value of x, we can rearrange the formula as:

[tex]$x = z\sigma + \mu$[/tex]

To find the z-score, we can use a standard normal distribution table or a calculator. For the 5th percentile, the z-score is approximately -1.645.

Plugging in the values, we get:

[tex]$x = -1.645 \times 10 + 60 \approx 43.55$[/tex]

If the manager randomly selected 4 of the overripe pieces for the first donation package, what is the probability that all of them are apples?
Write your answer as a decimal rounded to four decimal places.

Answers

Answer:

The probability of selecting an apple from the overripe fruit is 5/8. Since there are no replacement, the probability of selecting another apple from the remaining overripe fruit is 4/7, and the probability of selecting another apple after that is 3/6, and the probability of selecting another apple after that is 2/5. Therefore, the probability of selecting all apples is:

(5/8) × (4/7) × (3/6) × (2/5) = 0.0429

Rounded to four decimal places, the probability is 0.0429.

d. Calculate the number of cars produced in year 2020. (2)
e. Find the percentage change of production from year 2018 to 2020

Answers

The employees work in the production, service, and sales sections is 3/4 of total number. 1/4 of the employees work in other sections. The total number of employees in the factory is 14,400. The number of cars produced in 2020 is 439,875. The production decreased by 2.25% from 2018 to 2020.

Let the total number of employees in the factory be represented by the variable x. Then, the fraction of employees in the production section is 1/3x, the fraction in the service section is 1/4x, and the fraction in the sales section is 2/5 of the remaining employees, which is (1 - 1/3 - 1/4) x = 7/60x. Therefore, the fraction of employees in the production, service, and sales sections is:

1/3x + 1/4x + 7/60x = 15/20x = 3/4x

The fraction of employees in other sections is the remaining fraction after accounting for those in the production, service, and sales sections:

1 - 3/4x = 1/4x

Let the number of employees in the sales section be represented by the variable y. Then, the number of employees in the production section is y + 6000, and the number of employees in the service section is (1/4)x. Therefore, the total number of employees in the factory is:

y + 6000 + (1/4)x + y + 7/60x + 3/4x = 1x

Simplifying this equation, we get:

5/12x + 2y = 6000

we can find their sum as:

x + y = (12/5)(6000) = 14,400

The number of cars produced in 2019 is:

450,000 x 1.15 = 517,500

The number of cars produced in 2020 is:

517,500 x 0.85 = 439,875

The percentage change in production from 2018 to 2020 is:

[(439,875 - 450,000)/450,000] x 100% = -2.25% (rounded to two decimal places)

Therefore, the production decreased by 2.25% from 2018 to 2020.

Pls help i will give brainiest

Answers

Answer:

1.   No, the side lengths 3, 5, and 9 cannot make a triangle.

2.  If you are scaling an object by ¹/₃, it makes the object smaller.

     If the real object is 30 inches long, it is 10 inches once it is scaled.

3.  A cube has 6 faces.

     To find the volume, cube the side length:  6³ = 216 in³

Step-by-step explanation:

Question 1

According to the Triangle Inequality Theorem, the sum of any two sides of a triangle is greater than the length of the third side.

As the sum of the two sides measuring 3 and 5 is 8, and 8 is not greater than 9, the side lengths 3, 5, and 9 cannot make a triangle.

Question 2

Scaling an object reduces or enlarges its size. When scaling an object:

If the scale factor is greater than 1, the object becomes larger. If the scale factor is between zero and 1, the object becomes smaller.

Therefore, if you are scaling an object by ¹/₃, the object becomes smaller, since ¹/₃ is between zero and 1.

To scale length, simply multiply the length by the scale factor.

Therefore, if a real object is 30 inches long, its length once it is scaled is:

[tex]\implies \sf 30 \times \dfrac{1}{3}=\dfrac{30}{3}=10\;inches[/tex]

Question 3

A cube is a three-dimensional solid shape with six square faces.

The volume of a cube is the product of its width, length and height.

If the side of a cube measures 6 inches, its volume is:

[tex]\begin{aligned}\implies \sf Volume &=\sf 6 \times 6 \times 6 \\&= \sf 36 \times 6 \\&= \sf 216\;in^3\end{aligned}[/tex]

Answer:

See below, please.

Step-by-step explanation:

Ans 1.

In order to make a triangle, three line segments are needed, and the sum of the lengths of any two sides must be greater than the length of the remaining side. The side lengths 3, 5, and 9 cannot make a triangle because 3 + 5 is less than 9, which violates the triangle inequality.

Ans 2.

Scaling an object by 3 makes the object larger, as each dimension (length, width, and height) is multiplied by 3. If the real object is 30 inches long and is scaled by 3, it will be 90 inches long.

Ans 3.

A cube has 6 faces. To find the volume of a cube when one side measures 6 inches, we use the formula V = s^3, where s is the length of one side. Plugging in s=6, we get V = 6^3 = 216 cubic inches.

a quiz consists of three true or false questions. what is the probability that there are exactly two true answers?

Answers

The probability of getting exactly two true answers in a quiz that consists of three true or false questions is 3/8 or 0.375. Here's how to get the answer:



There are three possible scenarios where you can get exactly two true answers: T T F, T F T, F T T
To calculate the probability of each scenario, you need to know the probability of getting a true answer (T) or a false answer (F). Since each question is independent, the probability of getting a true or false answer is 0.5.
Scenario 1: T T F,The probability of getting two true answers and one false answer is: P(T T F) = 0.5 x 0.5 x 0.5 = 0.125
Scenario 2: T F T,The probability of getting one true answer and two false answers is:P(T F T) = 0.5 x 0.5 x 0.5 = 0.125
Scenario 3: F T T,The probability of getting one false answer and two true answers is:P(F T T) = 0.5 x 0.5 x 0.5 = 0.125



To get the probability of getting exactly two true answers, you need to add the probabilities of the three scenarios:P(2 True Answers) = P(T T F) + P(T F T) + P(F T T) = 0.125 + 0.125 + 0.125 = 0.375.Therefore, the probability of getting exactly two true answers in a quiz that consists of three true or false questions is 3/8 or 0.375.

The vertex for the quadratic function and the range of the function are determined in the following answer.The given quadratic function [tex]isy = -32 - 2(x - 1)²[/tex]

It is noted that the quadratic function is in the vertex form, i.e.,[tex]y = a(x - h)² + k[/tex]

where (h, k) is the vertex of the parabola. Comparing the given function with the vertex form of the quadratic equation, we get the value of the vertex, i.e.,(h, k) = (1, -32).This implies that the vertex of the given quadratic function is located at (1, -32).Since the coefficient of the quadratic term is negative in the given function, the parabola opens downwards, and the vertex is the highest point on the graph.Therefore, the vertex (-32, 1) is the highest point on the graph of the given quadratic function. The range of a function is the set of all possible values that the function can attain. The given quadratic function is in the form y = a(x - h)² + k where a, h, and k are constants.

Since the coefficient of the quadratic term is negative in the given function, the parabola opens downwards. Therefore, the range of the given function is (-∞, -32].Hence, the range of the given quadratic function is[tex](-∞, -32].[/tex]

Todd is training for a marathon. The following histogram summarizes the number of kilometers that he ran each day.

Answers

The probability that Todd runs more than 15kms tomorrow is 38.46%.

Define probability?

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula.

Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

Moreover, the proportion of positive outcomes cannot be negative.

Here in the question,

Probability = No.of days with more than 15kms run/total no.of days.

= 5/2+3+3+5

= 5/13

The vertices of a square are located at (0, 2), (2, 0), (0, -2), and (-2, 0).
Select all transformations that will carry this square onto itself.
A reflection across the line y = x
B reflection across the line y = -X
C reflection across the x-axis
D 45° rotation about the origin
E 90° rotation about the origin

Answers

Answer:

Step-by-step explanation:

A reflection across the line y = x will not carry the square onto itself, since the vertex (0, 2) would be reflected to (2, 0) which is not a vertex of the original square.

A reflection across the line y = -x would also not carry the square onto itself, since the vertex (0, 2) would be reflected to (−2, 0) which is not a vertex of the original square.

However, a reflection across the x-axis would carry the square onto itself since all of the vertices lie in the same quadrant, and reflecting across the x-axis does not change their signs.

A 45° or 90° rotation about the origin would also carry the square onto itself since the square has rotational symmetry of order 4.

Therefore, the correct answers are C, D, and E.

Help me find the Lateral Area and the Surface Area

Answers

Answer:

Step-by-step explanation:

The lateral area consists of 2 trapezia and 2 rectangles.

= 2 * 1/2 * 4 *(4 + 6) + 2 * 9 * length of the sloping line

= 40 + 18 * length of the sloping line.

Find the length of the sloping lines:

Consider the right triangle whose height is 4 ft.

The trapezium is isosceles so the base of this triangle

= (6 - 4)/ 2 = 1 ft.

By Pythagoras:

Sloping line = √(1^2 + 4^2) = √17

So lateral area

= 40 + 18√17.

= 114.22 ft^2 to nearest hundredth

Total area =

40 + 18√17 + 4*9 + 6*9

= 130 + 18√17

= 204.22 ft^2 to nearest hundredth

Good start.

Surface area:

Area of 2 trapezoids: 2 ((4+6)/2*4) = 40

Area of two side rectangles: [tex]2*9*\sqrt{17}=18\sqrt{17}[/tex] (I got root 17 from constructing a right triangle from the altitude just like last time and then finding the missing side using pythag)

Area of top rectangle: 4*9 = 36

Area of bottom rectangle: 6*9 = 54

Summing these up we get [tex]130+18\sqrt{17}[/tex]

Lateral area is the area excluding the bases (correct me if i'm wrong) so it will be [tex]130+18\sqrt{17}-40=90+18\sqrt{17}[/tex] (we need to subtract the areas of the trapezoids).

Which choice would transform the pre-image to the composite image? Make sure the letter for each vertex matches! Select one: a. Reflect across the y-axis and translate 4 down and three left. b. Rotate 180° and reflect across the x-axis. c. Rotate 90° and translate 4 up and 3 right. d. Reflect across the x-axis and translate up 4 and right 3.

Answers

d. Reflect across the x-axis and translate up 4 and right 3, this transforms the pre-image to the composite image.

What is composite image?

A composite image is the result of applying multiple transformations to a given pre-image. It is formed by first applying one transformation to the pre-image and then applying another transformation to the resulting image, and so on.  The final result is the composite image.

Let's analyze the given options:

a. Reflect across the y-axis and translate 4 down and three left.

This transformation would reflect the pre-image across the y-axis, which would change the signs of the x-coordinates, and then translate it 4 units down and 3 units left. However, this transformation would not result in the composite image provided.

b. Rotate 180° and reflect across the x-axis.

This transformation would rotate the pre-image 180 degrees counterclockwise around the origin, which would change the signs of both the x and y-coordinates, and then reflect it across the x-axis. This transformation would not result in the composite image provided.

c. Rotate 90° and translate 4 up and 3 right.

This transformation would rotate the pre-image 90 degrees counterclockwise around the origin, which would swap the x and y-coordinates and negate the new x-coordinate, and then translate it 4 units up and 3 units right. This transformation would not result in the composite image provided.

d. Reflect across the x-axis and translate up 4 and right 3.

This transformation would reflect the pre-image across the x-axis, which would change the signs of the y-coordinates, and then translate it 4 units up and 3 units right. This transformation would result in the composite image provided.

Therefore, the correct answer is d. Reflect across the x-axis and translate up 4 and right 3.
