For this case we have an equation in which we must apply operations to rewrite it in an equivalent way. We must start by raising both sides of the equation to the square. Thus, we eliminate the square root of the left side of equality and finally solve the binomial of the right side of equality.
So we have:

By definition:

Thus,
is equivalent to

Answer:
Step-by-step explanation:
Let d be the diameter of the wheel.
Circumference = πd
(35.325 m)/(25 revolutions) = (1.413 m)/revolution
πd = 1.413
d = 1.413/π = 0.45 m
Answer:
Atleast 4 women
Step-by-step explanation:
Ratio of
Women to men = 2 : 7
Number of women needed to maintain the ratio if there are 14 men on the roster :
The minimum number of women required :
(2 : 7) * number of men in roster
(2 / 7) * 14
2 * 2 = 4 women
Atleast 4 women are required to main the ratio
