Answers

Answer:

To calculate the size of the serving angle A in the diagram of the volleyball court, you can use trigonometry.

You have the following information:

The distance from point A to point C is 9 meters.

The distance from point A to point B is 31 meters.

To find angle A, you can use the inverse tangent (arctan) function:

A≈arctan(3.444)≈73.48

∘

Rounded to the nearest degree, the size of the serving angle A is approximately 73 degrees.

Step-by-step explanation:

Sure, I'll explain it in a simpler way:

Imagine you're standing at point A on the volleyball court, and you want to serve the ball towards point C or point B. Point C is 9 meters away, and point B is 31 meters away from you.

To find out how wide the angle is between where you stand (point A) and where you want to serve the ball (between points C and B), we can use a special math trick. It's like saying, "How much do I need to aim to the left or right?"

We use something called "arctan" to figure it out. When we do the math, we find that the angle A is about 73 degrees. So, you need to aim your serve at about a 73-degree angle to get the ball between points C and B on the other side of the court.

Step-by-step explanation:

The Waist to Hip Ratio (WHR) is a ratio, commonly expressed as a decimal that has been shown to be a good predictor of possible cardiovascular problems in both men and women. If a male has a WHR greater than 1, he is considered to be at high risk for cardiovascular problems. Calculate the WHR of a male with a waist measurement of 40 inches and a hip measurement 2 inches less.

Answers

40waist - 2 =38 hip
you divide the waist number by hip number

40/38= 1.05

A pool can be filled to 15,000 gallons of water. It takes 9 gallons per minute to fill the pool. How much minutes does it take to fill the pool?

Answers

Answer:

1666.7 minutes

Step-by-step explanation:

To find out how many minutes it takes to fill the pool, you can use the formula:

Time (minutes) = Total volume / Flow rate

In this case, the total volume of the pool is 15,000 gallons, and the flow rate is 9 gallons per minute.

Time (minutes) = 15,000 gallons / 9 gallons per minute

Time (minutes) = 1,666.67 minutes (rounded to two decimal places)

So, it takes approximately 1,666.67 minutes to fill the pool.

Two angles that can be trisected with a straightedge and compass are a 90angle and a _____ angle.A. 9
B. 75
C. 45
D. 90

Answers

The correct answer is:

C) 45.

Explanation:

An angle of measure $(2\pi)/(N)$ can be trisected if and only if N is not divisible by 3.

A 45° angle in radians is $(\pi)/(4)$ . Setting up a proportion, we can find the value of N to determine if this fits:

$(\pi)/(4)=(2\pi)/(N)$

Cross multiply:

$\pi * N = 4 * 2\pi \n N\pi = 8\pi$

This means N = 8, and is not divisible by 3; thus the 45 degree angle is trisectible.

the answer on apex is 45°
