Answer:

27 in²

Step-by-step explanation:

The area (A) is calculated as

A = πr² ( r is the radius ) , then

A = π × 3² = 3 × 9 = 27 in²

It takes 13 more copies of the angle for the last angle to overlap the first horizontal ray. What is the measure of each angle?
nalin [4]
Missing part in the heading of the question:
For this question, use the diagram shown. The diagram shows the result of constructing a copy of an angle adjacent to one of the rays of the original angles. Assume the pattern continues.

Answer:
measure of each angle = 24°

Explanation:
The diagram shows two angles, if we add 13 more copies, the number of angles would be 15 angles

Now, when the 15 angles are drawn, the last angle would overlap with the first horizontal ray.
This means that the angles form one complete rotation around the point.

This means that the sum of the 15 angles together is 360°.

We know the all 15 angles are equal. Assume that the measure of each is x.
15 x = 360
x = 360 / 15
x = 24°

Hope this helps :)

Mollie watches a film that lasts 130 min it begins at 6:15 pm. What time did it end?
Natalka [10]
Answer:

Starts at 6:15

Note: An hour is 60 minutes.

So an hour after 6:15 is 7:15 and an hour after that is 8:15. Now just add another 10 minutes and you get 8:25.

So the film ended at 8:25.

NEED HELP.
kirza4 [7]

Answer:

For instance, if the point (1, 3) is on the graph of the function, then the point (3, 1) is on the graph of the inverse. That is, if you start with x = 1, you will go to y = 3; then you plug this into the inverse, and you'll go right back to x = 1, where you started from.

Craig Campanella and Edie Hall both have night jobs. Craig has every thirteenth night and Edie has every Fifth night off. How of
Andrews [41]

Craig has every 13th night and Edie has every 5th night off.

You have to find LCM - the Least Common Multiple that is the smallest ("least") number that both 13 and 5 will divide into.

Since numbers 13 and 5 are both prime, then LCM(13,5)=13·5=65.

This means, they will have the same every 65th night off.

What is the density ?
zhannawk [14.2K]
Density is the degree of compactness of a substance. It is the degree of consistency measured by the quantity of mass per unit  volume. It is the relationship between the mass of the substance and the amount of space it takes up. I hope it helps.
