Sadie has $14,685 in a savings account. The interest rate is 13% per year and is not compounded. To the nearest cent, how much will she have in one year? use the formula I = PRT, where I is the interest earned, p is the principal, R is the interest rate expressed as a decimal, and T is the time in years.

round your answer to the nearest cent

$16,594.05

Step-by-step explanation:

13 * 14,685/100 = 1,909.05

14,685 + 1,909.05 = 16,594.05

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
