The area of wood needed for the frame is 5. 5 + 106 square inches. Option A
<h3>How to determine the area</h3>
The amount of wood needed for the window frame will be equal to area of window frame.
It is important to note that the upper part of window is semicircle
Area of the upper part = π
where,
R = Outer radius,
r = Inner radius.
Area of upper part = π ×
Area of upper part = 11π/2
Area of upper part = 5. 5π
To find the area of the lower part, it is important to note that the area of lower part of frame will be area of 3 different rectangles. Two are the same rectangles with length 48 inches and width 1 inch and one rectangle with length 10 inches (12-2) and width 1 inch.
Area of lower part = 2 × 48 × 1 + 10 × 1
Area of lower part = 96 + 10
Area of lower part = 106 inches
Thus, the area of wood needed for the frame is 5. 5 + 106 square inches. Option A

Answer:
Q1) D
Q2) C
Step-by-step explanation:
Q1)
y ∝ x
y = kx
Let x=-1,y=2
2 = k(-1)
k = -2
Q2)
directly (y=kx)
Let x=2,y=4
4 = k(2)
k = 2
y = 2x
inverse (y = k/x)
Let x=2,y = 4
4 = k/2
k = 8
xy = 8

Answer:
The answer is below
Step-by-step explanation:
1. COST Mr. Rivera wants to purchase a riding lawn mower, which is on sale for 15% off the marked price. The store charges sales tax 6.5% on all sales. Write a function p(x) that represents the price after a 15% discount. Write a function t(x) that represents the total cost with sales tax. Write a composition of functions that represents the total cost of a riding lawn mower on sale. How much will Mr. Rivera pay for a riding lawn mower that has a marked price of $3000?
Solution:
a) Let x represent the marked price and p(x) represent the price after discount. Since a discount of 15% is given, the price would be:
p(x) =
b) If x = discounted price and t(x) = total cost with sales tax, then:
t(x) =
c) Let t(x) represents the total cost with sales tax
