Finding a common denominator<span> makes it possible to add two fractions because it allows us to </span>write each<span> fraction as a multiple of a </span>common<span> (usually smaller) fraction. Subtracting fractions works the same way; find a </span>common denominator<span> so that the fractions involved are in the same terms.

This is calculated using the formula of: A = Pe(rt), where A is the total amount, P is the principal amount, e is mathematical constant approximately equal to 2.71828, r is the rate of interest, then t is the time in years.
Given we have the P as $12,000, r is 0.064 and t is 12, we expressed these values to the formula as;
A = Pe(rt)
A = 12,000.e(0.064 x 12)
A = 12,000 x 2.71828e
A = 12,000 x 2.155
A = $25,860
Therefore the money that Ann will have in 12 years is $25,860.
Answer:
5.000 ft
Step-by-step explanation:
The formula for the volume of a cylinder is
V = πr²h
Data:
V = 785.4 ft³
h = 2r
Calculations:
V = πr²h = πr²(2r) = 2πr³
Divide each side by 2π
Take the cube root of each side
![r = \sqrt[3]{\frac{V }{2\pi}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7BV%20%7D%7B2%5Cpi%7D%7D)
![= \sqrt[3]{\frac{785.4 }{2\pi }}](https://tex.z-dn.net/?f=%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B785.4%20%7D%7B2%5Cpi%20%7D%7D)
![= \sqrt[3]{125.00}](https://tex.z-dn.net/?f=%3D%20%5Csqrt%5B3%5D%7B125.00%7D)
= 5.000 ft
The radius of the cylinder is 5.000 ft.
