You deposit $3000 into a money-market savings account which pays 4.8% compounded quarterly, and you make no withdrawals from or

faust18 [17]

Answer:

$5265.71

Step-by-step explanation:

We have been given that you deposit $3000 into a money-market savings account which pays 4.8% compounded quarterly.

We will use future value formula to solve our given problem.

$FV=C_0\times (1+r)^n$ , where,

$C_0=\text{Initial amount}$ ,

r = Rate of return in decimal form,

n = Number of periods.

$4.8\%=\frac{4.8}{100}=0.048$

$n=3\times 4=12$

$FV=\$3,000\times (1+0.048)^{12}$

$FV=\$3,000\times (1.048)^{12}$

$FV=\$3,000\times 1.7552354909370114$

$FV=\$5265.7064\approx \$5265.71$

Therefore, there will be $5265.71 in your account at the end of those 3 years.

Which property is used to simplify the expression 5(3x +18) to 15x+90

natka813 [3]

Answer:

Distributive

Step-by-step explanation:

You distribute the 5 into 3x+18, multiplying it by each part of the equation (each part is separated by one of these signs: +, -, x, or /) to get 15x (from 5 x 3x) plus 60 (from 5 x 18).

Help plz I'm desperate

lutik1710 [3]

1st month = 18 + $\frac{3}{4}$ = 18 $\frac{3}{4}$ inches

2nd month = 18 $\frac{3}{4}$ + $\frac{3}{4}$ = 19 $\frac{1}{2}$

3rd month = 19 $\frac{1}{2}$ + $\frac{3}{4}$ = 20 $\frac{1}{4}$

4th month = 20 $\frac{1}{4}$ + $\frac{3}{4}$ = 21

5th month = 21 + $\frac{3}{4}$ = 21 $\frac{3}{4}$

<u>Grace:</u>

Because Anna is $\frac{9}{4}$ inches shorter than Grace, we can start the count from the third month:

1st month = 20 $\frac{1}{4}$

2nd month = 21

3rd month = 21 $\frac{3}{4}$

4th month = 21 $\frac{3}{4}$ + $\frac{3}{4}$ = 22 $\frac{1}{2}$

5th month = 22 $\frac{1}{2}$ + $\frac{3}{4}$ = 23
