Answer:
L = 12
W = 6
Step-by-step explanation:
W = 2L
A = L * W
A = 72
72 = L * 2L
72 = 3L
24 = L (you have to divide by 2)
L = 12
W = 6
Varying inversely means y=a number divided by x
find the number: 7=k/5 =>k=35
so the equation is y=35/x
A = π*r^2
r = √(A/π) = √(45/π) ≈ 3.78
The radius is approximately 4 inches.
Answer:
?
Step-by-step explanation:
Answer:
One-half squared is one-fourth.
Step-by-step explanation:
When you divide fractions, you multiply the first term by the reciprocal of the second term. In this example, instead of multiplying 1/2 by 1/4, you now multiply 1/2 by 4. Therefore, one half is equal to 2 fourths.
