Answer:
The diameter of a circle with an area of 100 square miles is 20/√π miles.
Step-by-step explanation:
Area =100 = πr^2.
diameter = d = 2r.
100 = πr^2.
100/π = r^2.
√(100/π) = r.
10/√π = r.
d = 2r.
d = 2 * 10/√π.
d = 20/√π
Answer:
$2800
Step-by-step explanation:
6/100 x 2500 = 150
150 x 2 = 300
2500 + 300 = $2800

Answer:
The equivalent to -(-5.25) = 5.25
Step-by-step explanation:
Given

We need to determine the equivalent to -(-5.25)
some of the sign rules are:
+(+) = +
−(−) = +
+(−) = -
−(+) = -
Thus,

Applying the rule: -a(-a) = a

Therefore, the equivalent to -(-5.25) = 5.25
