Answer:
about 4650 square inches
Step-by-step explanation:
The area is the product of length and width. Each conversion factor cancels a unit we don't want and replaces it with a unit we do want.
(1.5 m)(2 m)((1 in)/(0.0254 m))^2 = 3/.00064516 in^2 = 4650.0093... in^2
≈ 4650 in^2
The photograph has an area of 4650 square inches.
V = pi r^2h
V = 3.14(3)^2(9)
V = 3.14 x 9 x 9
V = 254.34 cm^3
Answer:
14
Step-by-step explanation:
3 1/2 × 4
Convert 3 1/2 to an improper fraction.
7/2 × 4
7/2 × 4/1
Multiply.
(7× 4) / (2 × 1)
28 / 2
= 14
It takes 8 dozens of flour.
5x4=20 so the person needs 4 times more than 2 dozens. 2x4=8 therefor, the person needs 8 dozens of flour.
We have that
[(x²+2x+1)/(x-2)]/[(x²-1)/(x²-4)]
we know that
(x²+2x+1)---------> (x+1)²
(x²-1)------> (x+1)*(x-1)
(x²-4)----->(x+2)*(x-2)
so
[(x+1)²/(x-2)]/[(x+1)*(x-1)/(x+2)*(x-2)]
[(x+1)²*(x+2)*(x-2)]/[(x-2)*(x+1)/(x-1)]
[(x+1)*(x+2)]/[(x-2)*(x-1)]
the answer is
[(x+1)*(x+2)]/[(x-2)*(x-1)]
