Option A
Answer:
Step-by-step explanation:
Use KCF method for fraction division.
Keep the first fraction
Change the operation to multiplication
Flip the second fraction.
1) 3÷ (1/4) = 
2) 7 ÷ (1/2) = 
3) (1/5) ÷ (1/20) = 
4) (1/2) ÷ (1/10) = 
5) (1/7) ÷ 3 = 
Answer:
18pi, or 56.52
Step-by-step explanation:
To start off, if you were to find the area of any whole circle, you would use the formula: pi x radius^2 = area of circle
However, since this is a semi-circle (half of a whole circle) you would divide the whole expression by 2, and then solve:
(pi x radius^2)/2 = area of semi-circle
(pi x 6^2)/2 = area of semi-circle
(36 x pi)/2 = area of semi-circle
18 x pi = area of semi-circle
18 x 3.14 = area of semi-circle
56.52 = area of semi-circle
Answer:
D) 3/2(X-4)
Step-by-step explanation:
Invert and multiply to get:
3(x+4)/2(x²-16)
factor the bottom
3(x+4)/2(x+4)(x-4)
The (x+4)’s cancel out, and you’re left with
3/2(X-4)
