Answer:
3 
inches long
Step-by-step explanation:
Find how long the paper will be by dividing 11 by 3. This will find how much 1/3 of the 11 inch paper is.
11/3
= 3
So, if she cuts the paper, the paper will be 3 inches long

Answer:
27.324$
Step-by-step explanation:
To find out what 8% of 25.30 is, divide 8 by 100 and get 0.08.
Then, multiply 25.30 by 0.08 and get your answer of 2.024. So, 8% of 25.30 is 2.024.
Since we must add the 8%, we must add 2.024 and 25.30 together. The answer will be 27.324.
Rounded, the answer will be 27.32$
Therefore, the answer is 27.32$.

Answer:
T.A. = 144 + 36√3 units²
Step-by-step explanation:
∵ The total surface area of the pyramid = the sum of the area of
the four faces (one base and 3 side faces)
∵ The 3 side faces have the same dimensions 12 , 10 , 10
∴ the area of the 3 faces = 3 × 1/2 × 12 × h
∵ The height of each triangle is ⊥ to its base
∵ The triangle are isosceles
∴ The height bisects the base
∴ h² = 10² - 6² = 64
∴ h = √64 = 8
∴ The area of the 3 triangles = 3 × 1/2 × 12 × 8 = 144 units²
∵ The base is equilateral Δ with side length 12
∵ Area equilateral triangle = 1/4 × s² × √3
∴ The area of the base = 1/4 × (12)² × √3 = 36√3 units²
∴ T.A. = 144 + 36√3 units²
Y-585 = -7.5(x-15)
y = -7.5x - 7.5(-15) + 585
y = -7.5x + 697.50
C = -7.5(52) + 697.50 = $307.50
