Answer:
Step-by-step explanation:
The square base measures 8 inches by 8 inches. The slant height is 10 inches.
The formula for determining the area of the square base of the pyramid is l^2. Therefore,
Area of the base = 8^2 = 64 inches^2
The formula for determining the perimeter of the square base is
4l. It becomes
4 × 8 = 32 inches
The amount of construction paper needed to make this pyramid is the total surface area of the pyramid. Therefore,
Total surface area = (1/2 × 32 × 10) + 64
= 160 + 64 = 224 inches^2
Answer:
A reflection of D over line l would simply look like a backwards D. Reflecting it again over the line m would make it look like it did originally, a normal D.
Step-by-step explanation:
Unit cost to sales price is 1:4.....or 1/4
1 / 4 = 33.85 / s.....1 unit cost to 4 sales price = 33.85 unit cost = s sales price
cross multiply
(1)(s) = (4)(33.85)
s = 135.40 <=== selling price
