Answer:

The correct answer is A. 14%

Step-by-step explanation:

Let's find out the effective annual interest rate for both loans, this way:

1st Loan:

Amount of the loan = $ 500 Interest rate = 12% = 0.12

Total interests for the year = 500 * 0.12 = $ 60

2nd Loan:

Amount of the loan = $ 250 Interest rate = 18% = 0.18

Total interests for the year = 250 * 0.18 = $ 45

Total Interests for both loans = 60 + 45 = $ 105

Effective annual interest rate = Total interest for both loans/Amount of the loans

Effective annual interest rate = 105/750 = 0.14 = 14%

Answer:

The percentage error is 3.6 % .

Step-by-step explanation:

Formula

$Error\ percentage = \frac{Error\times 100}{Exact\ value}$

$Error = \left |Approx - Exact \right |$

As given

Annie estimates that the height of a bookcase is 78.25 in. The actual height is 75.50 in.

Here

Approx value = 78.25 in

Exact value = 75.50 in

$Error = \left |78.25 - 75.50\right |$

Error = 2.75

Put in the formula

$Error\ percentage = \frac{2.75\times 100}{75.50}$

$Error\ percentage = \frac{275}{75.50}$

Error percentage = 3.6 %

Therefore the percentage error is 3.6 % .

Nina [5.8K]

Given the time t = 2 seconds, simply plug in it to the equation.
h = - 16(2)² + 541
= - 16(4) + 541
= - 64 + 541
h = 477 feet
