Answer:
B) 12
Step-by-step explanation:
C is the circumference, d is the diameter, and r is the radius. They are related by the following equations:
d = 2r
C = πd = 2πr
If d = 6.0, then r = 3.0.
If C / C' = 0.25, then:
(2πr) / (2πr') = 0.25
r / r' = 0.25
3 / r' = 0.25
r' = 12

Answer:
Simplify the expressions inside parentheses ( ), brackets [ ], braces { } and fractions bars.
Evaluate all powers.
Do all multiplications and divisions from left to right.
Do all additions and subtractions from left to right.
We are given:
The ratios of the number of hybrid vehicles to the total number of vehicles in the lot over a weekend (3 days) are equivalent.
This means that if on day 1, 100 hybrid cars parked and there are 300 cars in total, the ratio is 1 is to 3.
Therefore, on day 2 and 3, we can determine the number of hybrid cars parked given the total number of cars parked using the ratio, and vice versa.
If you mean (3x-4)^2, the answer will be 9x^2 - 24x + 16.
