The value of x in the given right triangle can be found with help of trigonometric-ratios, given an angle 16° and hypotenuse 37 units is 35.566657. On rounding off to nearest tenths we get 35.6 units.

What are trigonometric-ratios?

In a given right triangle, the ratios of different sides are represented as six trigonometric ratios which are cosine,sine,cosecant,cot,secant and tan.

Sin of an angle=[tex]\frac{side opposite to the angle}{hypotenuse of triangle}[/tex]

Cosine of an angle=[tex]\frac{side adjacent to the angle}{hypotenuse of the triangle}[/tex]

tan of an angle= [tex]\frac{side opposite to the angle}{side adjacent to the angle}[/tex]

And cosecant, secant and cot are the reciprocals of sine, cosine & tan respectively.

Here,on naming the given right triangle we can see that

∠A = 16° , AC=37 units and Side AB= x units

Applying cosine of angle  16°, we get

cos A=[tex]\frac{side adjacent to the angle}{hypotenuse of the triangle}[/tex]

Cos 16°=[tex]\frac{side adjacent to the angle}{hypotenuse of the triangle}[/tex]

Cos  16°= [tex]\frac{AB}{AC}[/tex]

0.961261= [tex]\frac{AB}{AC}[/tex] {Cos  16°=0.961261}

0.961261=[tex]\frac{x}{37}[/tex]    {AB=x and AC=37}

           x = 0.961261 (37)

           x = 35.566657

On rounding off to nearest tenths x=35.6 units

the equation that relates the time it took James to sort the supplies for b bags is: t = 1.5b

option D.

Sherry sorted enough supplies for 10 bags in 30 minutes (from 10:10 a.m. to 10:40 a.m.). Let's call the rate at which Sherry sorted the supplies "r."

Then, we can write:

r = 10 bags / 30 minutes

r = 1/3 bags per minute

Since James sorted twice as fast as Sherry, his rate is 2r:

2r = 2/3 bags per minute

To find the time it took James to sort b bags, we can use the formula:

time = (amount of work) / (rate of work)

In this case, the "amount of work" is b bags, and the "rate of work" is 2/3 bags per minute. So, we get:

time = b / (2/3)

time = (3/2) b

Therefore, the equation that relates the time it took James to sort the supplies for b bags is:

t = (3/2) b

So, the correct answer is (D) t = 1.5b.

To determine when the ball strikes the ground, we need to find the value of t when the height h(t) is 0.

The equation for the ball's height h at time t seconds after launch is:

h(t) = -4.9t^2 + 9.31t + 239.12

Setting h(t) to 0, we get:

0 = -4.9t^2 + 9.31t + 239.12

We can solve this quadratic equation using the quadratic formula:

t = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = -4.9, b = 9.31, and c = 239.12.

Answer: 6.12 seconds

Step-by-step explanation:

To find when the object strikes the ground, we need to find the time t when the height h(t) is equal to 0 (since the ground is at height 0). We have the equation:

h(t) = -4.9t² + 9.31t + 239.12

To find the time when the object strikes the ground, we need to find the value of t when h(t) = 0:

0 = -4.9t² + 9.31t + 239.12

This is a quadratic equation of the form at² + bt + c = 0, where a = -4.9, b = 9.31, and c = 239.12. We can solve this equation for t using the quadratic formula:

t = (-b ± √(b² - 4ac)) / 2a

Plugging the values of a, b, and c into the formula, we get:

t = (-(9.31) ± √((9.31)² - 4(-4.9)(239.12))) / (2(-4.9))

t = (-9.31 ± √(86.6161 + 4694.336)) / (-9.8)

t = (-9.31 ± √(4780.9521)) / (-9.8)

t ≈ (-9.31 ± 69.14) / (-9.8)

We will have two possible values for t:

t₁ ≈ (-9.31 + 69.14) / (-9.8) ≈ 6.12 (rounded to two decimal places)

t₂ ≈ (-9.31 - 69.14) / (-9.8) ≈ 8.00 (rounded to two decimal places)

Since the height function describes the motion of the ball from a platform, we can discard the negative solution as it represents an invalid time before the ball is launched. Thus, the object strikes the ground at approximately t ≈ 6.12 seconds.

The distance between the points (15, -17) and (-20, -5) is 37.

The distance formula is a mathematical formula used to find the distance between two points in a coordinate plane. It is derived from the Pythagorean theorem and can be used to find the distance between any two points, whether they are on the same line or on different lines.

We can use the distance formula to find the distance between two points:

[tex]\rm d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]

Let [tex]\rm (x_1,y_1)[/tex] = (15,-17) and [tex]\rm (x_2, y_2)[/tex] = (-20,-5)

Then, plugging into the formula, we get:

[tex]\rm d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]

[tex]\rm = \sqrt{(-20-15)^2 + (-5-(-17))^2}[/tex]

[tex]= \sqrt{(-35)^2 + (12)^2}[/tex]

[tex]= \sqrt{1225+144}[/tex]

[tex]= \sqrt{1369}[/tex]

= 37

Sure, I'll be happy to help you with your question. In order to find the measure of the missing angle and arc, we first need to know what type of angle and arc we are dealing with. If it is a central angle and arc, then the measure of the angle is equal to the measure of the arc. However, if it is an inscribed angle and arc, then the measure of the angle is half the measure of the arc.

Once we have determined the type of angle and arc, we can use the given information to solve for the missing measure. For example, if we are given the measure of the angle and the measure of the arc, we can use the formula for the measure of a central angle or inscribed angle to solve for the missing measure.

Brooklyn have to pay total for the 11 rides is $43 and for r rides she have to pay is $10+$3×r.

If Brooklyn goes on 11 rides, she will have to pay $10 for admission and $3 for each of the 11 rides she goes on. So her total cost would be:

$10 + (11 rides x $3/ride) = $10 + $33 = $43

If she goes on r rides, her total cost would be:

$10 + (r rides x $3/ride) = $10 + $3r

So, for example, if she goes on 15 rides, her total cost would be:

Based on the calculations using z-scores, we can conclude that the Grande Mocha Cappuccino at Ruth's Roast's has less sugar relative to the other drinks at its respective store than the Grande Mocha Cappuccino at Coffee Haven.

What is Coffee Haven?

"Coffee Haven" was used as an example name for one of the coffee shops in a previous question. It is not an actual coffee shop. The name was used to illustrate a point about comparing the sugar content of drinks between different coffee shops.

To compare the sugar content of the Grande Mocha Cappuccino between the two coffee shops, we can use z-scores to standardize the sugar content based on the mean and standard deviation of each shop's drinks.

For the first coffee shop, let's call it Coffee Haven, we know that the mean sugar content is 20g with a standard deviation of 8g. Therefore, the z-score for the Grande Mocha Cappuccino at Coffee Haven is:

z = (13 - 20) / 8 = -0.875

For the second coffee shop, Ruth's Roast's, we know that the mean sugar content is 16g with a standard deviation of 6g. Therefore, the z-score for the Grande Mocha Cappuccino at Ruth's Roast's is:

z = (13 - 16) / 6 = -0.5

Comparing the two z-scores, we see that the z-score for the Grande Mocha Cappuccino at Ruth's Roast's is greater than the z-score for the Grande Mocha Cappuccino at Coffee Haven. This means that the Grande Mocha Cappuccino at Ruth's Roast's has less sugar relative to the other drinks at its respective store than the Grande Mocha Cappuccino at Coffee Haven.

The probability that the manufacturer's claim is valid is 0.0037, or 0.37%.

The student question asks about the probability that the car manufacturer's claim of the hybrid car traveling at speeds more than 60 mpg is valid. The actual mpg is approximately normally distributed with a mean of 52 miles and a standard deviation of three miles.
To calculate the probability, we will use the Z-score formula:
Z = (X - μ) / σ
Where:
Z is the Z-score
X is the value we want to find the probability for (in this case, 60 mpg)
μ is the mean (52 miles)
σ is the standard deviation (3 miles)
Plug in the values into the Z-score formula:
Z = (60 - 52) / 3
Calculate the Z-score:
Z = 8 / 3 ≈ 2.67
Now we have the Z-score of 2.67, which tells us how many standard deviations above the mean the value of 60 mpg is. The next step is to use a Z-table (also known as the standard normal table) to find the probability.
Look up the Z-score in the Z-table:
For a Z-score of 2.67, the corresponding probability in the Z-table is 0.9963.

This means that 99.63% of the data falls below 60 mpg.
Find the probability that the claim is valid:
Since we want to find the probability that the car travels at speeds more than 60 mpg, we need to find the area to the right of the Z-score in the normal distribution curve. To do this, we subtract the probability from 1
Probability = 1 - 0.9963 = 0.0037
The probability that the manufacturer's claim is valid is 0.0037, or 0.37%.

If ∠1 and ∠2 are vertical angles and m∠22 = 180°, then m∠1 = 90°

Vertical angles are pairs of angles that are opposite to each other when two lines intersect. Vertical angles are always equal in measure. Therefore, if ∠1 and ∠2 are vertical angles, then:

∠1 = ∠2

We are also given that m∠22 has a measure of 180°. Since ∠1 and ∠2 are vertical angles, they form a straight line, and their measures add up to 180°. Therefore:

∠1 + ∠2 = 180°

Since ∠1  = ∠2, we can substitute ∠1 for ∠2 in the above equation:

∠1 + ∠1 = 180°

Simplifying the equation, we get:

2∠1 = 180°

Dividing both sides by 2, we get:

∠1 = 90°

Therefore, ∠1 has a measure of 90°.

The binomial distribution is used to calculate the probability of a certain number of successes in a fixed number of independent trials. In this case, the number of trials is 15, and the probability of success (i.e., a bearing not meeting the required specifications) is 10%.

b) The assumptions allow us to use the binomial distribution to calculate the probability of having a certain number of bearings fail to meet the required specifications in a sample of 15. Additionally, we assume that the true rate of rejection is 10%, which may not always be the case.
