Solve for y
y= 24
Therefore the equation should be
y = 24/x
So when x = 3
y = 24/3
y = 8

You want to study the effects of regular exercise on a person’s heart rate. You measure the heart rate of a person at rest and again after jogging in place for 5 minutes. The control group is every other student who enters the room. The experimental group is those students who are not in the control group.
Answers
Final answer:
The study described is an experimental study. The independent variable is regular exercise and the dependent variable is the person's heart rate. The control group is the group of students who do not exercise, while the experimental group is the group of students who engage in regular exercise.
Explanation:
The study described is an experimental study.
In an experimental study, the researcher directly manipulates the independent variable to determine its effect on the dependent variable. In this case, the independent variable is regular exercise and the dependent variable is the person's heart rate.
The control group is the group of students who do not exercise, while the experimental group is the group of students who engage in regular exercise. By comparing the heart rates of the two groups before and after exercise, the researcher can determine the effects of exercise on heart rate.
Which right triangular prism has the greatest volume?
Answers
Answer:
So Prism D has the greatest volume.
Step-by-step explanation:
Since volume of a triangular prism = A × h
where A = Area of base of prism
h = height
For prism (A) ⇒ Volume = ( 6 × 7 ) × 9
= 42 × 9 = 378m³
Prism (B) ⇒ Volume = ( 5 × 6 ) × 13
= 30 × 13 = 390m³
Prism (C) ⇒ Volume = ( 11 × 8 ) × 8
= 88 × 8 = 704m³
Prism (D) ⇒ Volume = ( 10 × 8 ) × 9
= 80 × 9 = 720m³
So prism D has the maximum volume.

What rate of simple interest is needed for $700 to double, in 3 years?
Answers
The rate of simple interest required for $700 to double in 3 years is found using the formula I=PRT. In this scenario, the rate comes out to be approximately 33.3%.
Explanation:The subject of this question is finding the rate required for simple interest to cause an investment of $700 to double in a duration of 3 years.
Generally, we use the formula for simple interest: I=PRT where P is the principal amount (700 in this case), I is the interest earned, R is the rate we want to find and T is the time period in years.
However, since the aim is for the $700 to double, the interest earned will be an additional $700, thereby making the total $1400. Thus, substituting these values into the formula, we get 700 = 700 * R * 3. Simplifying this, we find that R = 700/(700*3) = 1/3 or approximately 33.3%.
Hence, the rate of simple interest required for $700 to double in 3 years is approximately 33.3%.

R = 1/3 or 33.33%. So, the simple interest rate needed for $700 to double in 3 years is approximately 33.33%.
To find out the simple interest rate that is needed for $700 to double in 3 years, we can set up the equation based on the formula for simple interest, which is I = PRT (where I is the interest, P is the principal amount, R is the rate of interest, and T is the time period in years).
Since the student wants the money to double, the interest gained should be equal to the principal, which means I = $700. The time given is T = 3 years. Plugging these values into our formula, we get:
$700 = $700 × R × 3
By dividing both sides by $2100 ($700 ×3), the equation simplifies to:
R = $700 / $2100
Therefore, R = 1/3 or 33.33%. So, the simple interest rate needed for $700 to double in 3 years is approximately 33.33%.

The distance between the boats after 30 minutes is approximately 23.04 miles. Option C
How to find the distance between the two boats after 30 minutesTo find the distance between the two boats after 30 minutes, use the law of cosines. Let's denote the distance between the boats as "d".
We know that one boat is traveling at 24 miles per hour, and the other boat is traveling at 32 miles per hour. In 30 minutes (or 0.5 hours), the first boat would have traveled 24 * 0.5 = 12 miles, and the second boat would have traveled 32 * 0.5 = 16 miles.
Now, applying the law of cosines:
[tex]d^2 = (12)^2 + (16)^2 - 2 * 12 * 16 * cos(110^o)[/tex]
Calculating the equation:
[tex]d^2 = 144 + 256 - 384 * cos(110^o)[/tex]
Now, evaluate cos(110°):
cos(110°) ≈ -0.34202
Substituting the value:
[tex]d^2[/tex] = 144 + 256 - 384 * (-0.34202)
[tex]d^2[/tex] = 144 + 256 + 131.23808
[tex]d^2[/tex] ≈ 531.23808
Taking the square root:
d ≈ 23.04
Therefore, the distance between the boats after 30 minutes is approximately 23.04 miles.
Rounded to the nearest whole number, the answer would be 23 miles (Option C).

Two angles are complementary. The measure of the largest angle is two times the measure of the smaller angle. What is the measure of the larger angle?
Please help! :D
Answers
one of the angles is twice as large as the smaller one
let the larger angle be x, and the smaller = y
x = 2(y)
x + y = 90
Plug in 2y for x
2y + y = 90
simplify, combine like terms
2y + y = 90
3y = 90
isolate the y, divide 3 from both sides
3y/3 = 90/3
y = 90/3
y = 30
plug in 30 for y in the equation x + y = 90
x + (30) = 90
isolate the x, subtract 30 from both sides
x + 30 (-30) = 90 (-30)
x = 90 - 30
x = 60°
The measurement of the larger angle is 60°

John ,Rick , and Molli are painting a room together. It takes all of them 16 hours to paint the room to perfection. It takes John 8 hours to paint the room alone , and it takes Rick 2 hours to paint the room alone. What is the hourly rate it take’s of john to paint the room alone?
Answers
Rick's hourly rate is 1/2 of the room per hour.
Molli's hourly rate would be 3/8 of the room per hour.
It takes Molli 2 2/3 hours to paint the room alone.
Explanation
Since John paints the entire room (100%=1) in 8 hours, he would paint 1/8 of the room in 1 hour.
Since Rick paints the entire room (100%=1) in 2 hours, he would paint 1/2 of it in 2 hour.
We do not yet know Molli's rate, so we will call it x.
We know that 1/8+1/2+x = 1 hour.
We will use 8 as a common denominator:
1/8+4/8+8x/8 = 1
Adding the numerators,
(1+4+8x)/8 = 1
Multiply both sides by 8:
1+4+8x = 8
Add like terms:
5+8x = 8
Subtract 5 from both sides:
5+8x-5=8-5
8x=3
Divide both sides by 8:
8x/8 = 3/8
x = 3/8
Molli's rate is 3/8.
Since she can paint 3/8 of the room in 1 hour, we can set up the equation
3/8x = 1
Divide both sides by 3/8:
3/8x ÷ 3/8 = 1 ÷ 3/8
x = 1/1 ÷ 3/8 = 1/1 × 8/3 = 8/3
x = 2 2/3
This is the amount of time it takes Molli to paint the entire room.
John's hourly rate of painting a room alone is 1/8 of the room per hour, which is calculated from the time he takes to complete the job on his own.
The question asks for the hourly rate at which John can paint a room alone. Knowing that John takes 8 hours to paint the room by himself, we can find his hourly rate by understanding the concept of work rates in combination tasks. Since painting can be considered a task that involves continuous work, the rate at which the room gets painted relates directly to a painter’s work rate, which is the fraction of the room they can paint per hour. For John, his work rate is the reciprocal of the time he takes to paint the room alone, which in this case is 1/8 of the room per hour.
