Answer:

150 in²

Step-by-step explanation:

The surface area is the area of the 6 faces shown in the net.

Each face is a square with area = s² ( s is the side length )

here s = 5

surface area = 6 × (5 × 5) = 6 × 25 = 150 in²

find the amount in an account after years if invested$5000 at 6% per year and is compounded quarterly

stich3 [128]

Answer:

The amount of money in the account after t years is given by: $A(t) = 5000(1.015)^{4t}$

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Invested $5000 at 6% per year and is compounded quarterly

This means, respectively, that $P = 5000, r = 0.06, n = 4$

So, the amount of money in the account after t years will be given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

$A(t) = 5000(1 + \frac{0.06}{4})^{4t}$

$A(t) = 5000(1.015)^{4t}$

Ariel was able to read 15 pages in 12 minutes find the unit rate

Natali [406]

1.25 pages per minute is the unit rate because she reads at 15 pages per every 12 minutes so we would have to set it up as 15 divided by 12 which is 1.25.
