Answer:

9.43 ft

Step-by-step explanation:

First, we need to find the area of the entire circle(shaded & unshaded), which is 12.57, with a radius of 2 ft. Next, we find the area of the white area, and NOT the shaded area, which is 3.14, with a radius of 1 ft. Now, we need to subtract the white area(3.14) from the total area(12.57), which is 9.43.

Hope this helps!

Amanda and jamie are standing 25 feet apart and spot a bird in the sky between them the angle of elevation from Amanda is 25 fee

finlep [7]

Answer:

25.2294 feet

Step-by-step explanation:

We can solve this question drawing a triangle using the values given and then using the law of sines. (See image attached to know how to draw the triangle and use the values).

First we need to find the third angle of the triangle, that is, the angle in the vertix where the bird is:

y + 55 + 63 = 180

y = 62°

The relation between the angles and the distances are:

25 / sin(y) = x / sin(63)

25 / 0.8829 = x / 0.8910

x = 25 * 0.8910 / 0.8829 = 25.2294 feet

A student has 8 pints of iced tea in a pitcher. The amount of iced tea in the pitcher is a function of x, the amount of iced tea

Reptile [31]

Answer: The domain is:

0 pints ≤ x ≤ 8 pints.

Step-by-step explanation:

When we have a function:

y = f(x)

The domain is the set of the possible values of x (the possible inputs).

In this case, the value of x represents the amount of tea that she has poured from the pitcher.

Now, initialy the pitcher has 8 pints, so the smallest possible value of x is 0 pints (when she has not pured anithing) and the maximum value of x is 8 pints (when she has poured all the 8 pints).

So we have the domain:

0 pints ≤ x ≤ 8 pints

A group of college students were asked about their TV watching habits. Of those surveyed, 30 students watch The Walking Dead, 24

Usimov [2.4K]

Answer: 44 students

Step-by-step explanation:

Let Walking dead be denoted as W

Let Blacklist be denoted as B

Let Game of thrones be denoted as G

Total number of students that watch W = 30

W&G&B = 7

W&B only = 13-7 = 6

W&G only = 10-7 = 3

To get the number of people that watch W ONLY, we subtract those that watch W&B only (6), W&G only(3) and W&B&G(7) from 30. Hence,

W Only = 30 - 6- 3 - 7= 14 (14 students watch Walking dead only)

Total number of students that watch B =24

B&G&W = 7

B&W only = 13-7 = 6

B&G only = 16 - 7 = 9

Hence, those that watch B only = 24-6-9-7= 2 students.

Total number of students that watch G = 22

G&W&B = 7

G&B only = 9

G&W only = 3

Hence those that watch G only = 22-9-3-7 = 3 students.

Hence number of students that watch at least one show = W only + B only + G only + W&B only + W&G only + B&G only + W&B&G.

= 14+2+3+6+3+9+7 = 44 students.
