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:
PLEASE TAKE YOUR TIME AND THINK THROUGH EVERY PROBLEM. USE THE C.U.B.E.S STRATEGY WHEN NEEDED.
Step-by-step explanation:

The ratio is 1:2
Since you are told the ratio is 1:r, that means r is 2.
The unit rate is 2 cups sugar per cup of lemon juice.
Answer:
24
Step-by-step explanation:

Sum of the number and 6: 
Divide it by 3: 
Result is 4 more than one quarter of the number:
Multiply both sides by 12:
Simplify:
Expand:
Subtract 24 from both sides:
Subtract 3x from both sides:
The number is 24.
