First of all, you would use the FOIL method for -5(a + 3). This means to just multiply -5 to all of the values in the parenthesis. This would equal:

-5a -15 = -55

Then after, you would add 15 for both sides and get -5a = -40

Divide by -5 on both sides, you get a = 8.

What is the length of BC on in the right triangle below? Non
skad [1K]

Answer:

C. 20

Step-by-step explanation:

You need you use the Pythagorean Theorem to answer this. We are given the lengths of both legs of the right triangle.

a^2 +b^2 = c^2

If we plug the number given to us into the formula, we get

(12)^2 + (16)^2 = c^2

144 + 256 = c^2

400 = c^2

\sqrt{400} = C

20 = C

Brody deposited 8,001 in a savings account with simple interest. Four months later the account held 8,267.70. What is the intere
Travka [436]

Answer:

R = 0.8333%/month

(R = 9.9996%/year)

Equation:

r = (1/t)(A/P - 1)

Calculation:

Solving your equation:

r = (1/4)((8267.7/8001) - 1) = 0.00833333

r = 0.00833333

Converting r decimal to R a percentage

R = 0.00833333 * 100 = 0.8333%/month

Calculating the annual rate

0.8333%/month × 12 months/year = 9.9996%/year.

The interest rate required to get a total amount, principal plus interest, of $8,267.70 from simple interest on a principal of $8,001.00 over 0.333333 years (4 months) is 0.8333% per month.
