1) Find the area of the pizza assuming a uniform regular circular shape.

Area = PI * 0.25 * (D)^2

A1 = 3.14 * 0.25 * (12)^2 = 113.04 in^2

A2 = 3.14 * 0.25 * (8)^2 = 50.24 in^2

Pizza difference = 113.04 - 50.24 = 62.8 in^2

More pizza = 62.8/50.24 x 100 - 100 = 25 %

Max is stacking logs at his campground for firewood. After his first load of logs, he has 12 logs on the stack. After his sevent

Natasha2012 [34]

Answer:

Let L(n) be the function that gives the amount of logs stacked after n loads.

L(n) = 12 + 8(n-1)

Step-by-step explanation:

Let L(n) be the function that gives the amount of logs stacked after n loads.

Let's call for the moment the first load as L(0)

L(0)= 12

Let r be the number of logs carried in each load, then

L(n) = 12 + nr

Since L(6) (the seventh load) equals 60, we have

60 = 12 + 6r, and r = 8.

So a function for the number of loads starting from n=0 would be

L(n) = 12 + 8n

If we want to start with n=1, we simply change the variable

L(n) = 12 + 8(n-1) (n=1,2,3,...).

So L(1) = 12, L(2) = 20, L(3) = 28,...L(7) = 60 and so on.

The roof of a house seen from the front is an isosceles triangle \Delta ABC ΔABC with base 14.5 m and sides of length 8.5 m. Fin

melamori03 [73]

Answer:

4.4 m

Step-by-step explanation:

Draw the height of the triangle (perpendicular line from point A to line BC). Since ABC is an isosceles triangle, the height is a perpendicular bisector, so it splits the triangle into two congruent right triangles.

Use Pythagorean theorem to find the height.

c² = a² + b²

(8.5 m)² = (14.5/2 m)² + h²

h ≈ 4.4 m
