Ad libitum [116K]

Answer: 4.20 gigabyte

Step-by-step explanation:

Based on the information given in the question, the equation that can be used to determine the the number of gigabytes of data Peyton can use while staying within her budget will be:

48 + 3g = 60.60

3g = 60.60 - 48

3g = 12.60

g = 12.60/3

= 4.20

The number of gigabytes of data is 4.20g

Which of the following is the balance for a single $3,200 deposit in an account with an APR of 2.6% that compounds interest quar

Flauer [41]

Answer:

$FV= 3200(1+\frac{0.026}{3})^{3(6)}=3200 (1.008667)^{54}= 50994.590$

Step-by-step explanation:

For this case we can use the formula for the future value with compound interest given by:

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

For this case since the interest is compounded quarterly we have 3 periods each year, since we have 3 quarters in a year.

r represent the rate =0.026

t = 6 represent the number of years

P = 3200 represent the amount invested at the begin

If we apply the formula (1) we got:

$FV= 3200(1+\frac{0.026}{3})^{3(6)}=3200 (1.008667)^{54}= 50994.590$

So then the balance after 6 years would be approximately 50995 with the conditions provided.

Which of the sets of three dimensions could make a right triangle

hodyreva [135]

Answer:

B) 6, 8, 10

Step-by-step explanation:

All right triangles will follow the following theorem (Pythagorean theorem):

$a^2+b^2=c^2$ , where $a$ and $b$ are two legs of the triangle and $c$ is the hypotenuse. Out of all answer choices, only B) 6, 8, 10 follow this theorem.
