What is the equation for compound interest
sergey [27]
A = P(1 + r)^n

where A is the amount after n years, P = principal( initial amount), r = annual rate as a decimal fraction and n = number of years 

If interest is accumulated say monthly then it would be

A = P(1 + r/12)^12n

For quarterly replace the 12 by 4

Figure that represents 150%
diamong [38]
Suppose a square is 100%, 50%: the square is divided into two equal parts, and one of them is shaded, therefore it is 50%. 25%: the square is divided into 4 equal parts, and one of them is shaded, therefore it is 25%. 150%: there are two squares, each divided into 2 equal parts, and 3 of them is shadowed, therefore it is 150%

Does anyone know the answer to 7-8
alina1380 [7]
7 is \frac{9}{10} miles; the question includes the words "in all", which shows that the two fractions should be added together. To add fractions with the same denominator, you must simply add the numerators and keep the denominator unchanged.

8 is \frac{3}{4} yards of ribbon; this one also requires you to add the fractions-- the numerators should be added, but the denominator stays the same because the two fractions share the same denominator.
