Answer:

57%

Step-by-step explanation:

the table shows the following:

test scores for Test 1 = 62, 62, 66, 70, 70, 70, 78, 82, 82, 86

test scores for Test 2 = 68, 72, 72, 72, 72, 76, 80, 80, 80, 84, 88, 88

there are 7 tests with scores greater than or equal to 70 on test 1

there are 11 tests with scores greater than or equal to 70 on test 2

the percent change is the difference of the two amounts, 7 and 11, divided by the original amount, 7

4/7 = 57%

If she goes with the 25% off she will have to pay 28.80

if she uses the $15 off she will have to pay
$35.33 plus the $15 off would be 20.33 so she's better off going through doing it this way rather than the 25% off

Verify the Pythagorean Identity.

To solve this problem you must apply the proccedure shown below. You have that:

1+cot^2θ=csc^2θ (You have that cos^2θ+sin^2θ=1)<span>
1+(cos^2</span>θ/sin^2θ)=csc^2θ
1+(1-sin^2θ/sin^2θ)csc^2θ
sin^2θ+1-sin^2θ=csc^2θ
1/sin^2=csc^2 (You have that 1/sin=csc)

Answer:

D. 220.16 Square feet

Step-by-step explanation: The shaded area is the space in the square not filled by the circle. So we need to find the area of the circle. The formula for area of a circle is $A=\pi r^{2}$ . So we fill in this equation with the information we already know:

$A=\pi 16^{2}$

$A=3.14*16^{2}$ Simplify the exponents

$A=3.14*256$ Multiply

$A=803.84$

So now we know the area of the circle we have to find the area of the square because the circle is inside the square. It is a simple $32*32$ which is 1,024. Since we are looking for the shaded area we will subtract the area of the circle from the area of the square because the circle is not shaded.

1024-803.94= 220.16 square feet
