<span>To estimate the number of years for a variable to double, take the number 70 and divide it by the growth rate of the variable. This rule is commonly used with an annual compound interest rate to quickly determine how long it takes to double your money.</span>
<span>So 70÷4.5 = <span>15.5555556. So the answer is B</span></span>
So factor -27
-27=-1 times 3 times 3 times 3
∛(-1 times 3 times 3 times 3)=3 times ∛-1
remember that ∛-1=-1
2 times ∛-1=3 times -1=-3
now we have
5 times (-3)+18
5 times -3=-15
-15+18=3
answer is 3

Answer:
2:1
Step-by-step explanation:
Circle P has radius 14 feet.
The circumference of this circle is given by:
We plug in the radius to get:
Circle Q has diameter 14 feet.
The circumference of this circle is given by
We substitute the diameter d=14 to get,
The ratio of the circumference of P to the circumference of Q is
