Shandra's parents put $1,500 in her bank account for college tuition. At an interest rate

gavmur [86]

Answer:

$6,427.99

Step-by-step explanation:

-We first find the effective annual interest rate as follows:

$i_m=(1+i/m)^m-1\\\\=(1+0.0825/2)^2-1\\\\=0.084202$

#We the use this rate to find the compounded amount after 18 years:

$A=P(1+i_m)^n\\\\=1500(1.084202)^{18}\\\\=6427.99$

Hence, the amount after 18 years is $6,427.99

a strip of paper is 9/10 of an inch long. you need to cut the paper into 3/12 inch pieces. how many pieces will you be able to c

e-lub [12.9K]

We have to divide 9/10 by 3/12.

if we divide by a fraction, we can instead multiply by it's inverse:

$\frac{9}{12}/ \frac{3}{12} = \frac{9}{12} * \frac{12}{3}$

so now we count:

$\frac{9}{12} * \frac{12}{3} =\frac{9}{1} * \frac{1}{3}=3$

so we can cut exactly 3 pieces!
