A bank offers an annual simple interest rate of 8% on home improvement loans. Jake borrowed $17,000 over a period of 2 years. How much did he repay altogether?

A. $1,360
B. $2,720
C. $18,360
D. $19,720

Answers

Answer:

D

Step-by-step explanation:

Answer:

Step-by-step explanation:

We first find out the amount in dollars of interest accrued after 2 years  time.

Interest = Prt

where P is the principal, r is the rate and t is  time

8% written in decimal fraction → 8/100 → 0.08

Interest = 17000 × 8% × 2

Interest = 1700 × 0.08 × 2

Interest =  2,720 dollars

We add the principal and the interest to get full amount paid, so:

17000 + 2,720 = 19,720

Therefore the answer is D

Answers

Answer:

mRJN = 75°

Step-by-step explanation:

VJA = 15°

If the line VJ would continue through J and stop at a point that we now call Z. Then the new angle ZJN which is a vertically opposite angle to VJA would also be 15°

Angle VJE is supplementary to VJR and therefore also 90°

And if angle VJE is 90°, that means its supplementary angle EJZ is also 90°.

Angle EJN (supplementary to RJN) is simply EJZ - ZJN = 90° - 15° = 75°

Answers

That’s a lot probably distributive property or commutative

The steps to simplify the expression is:

Step 1 :

x (x-7y) + 4y(x- 7y) + z (x- 4y)

Step 2:

x² - 7yx + 4yx - 28y² + zx - 4zy

Step 3:

x² -28y² - 3yx + zx - 4zy

What is Expression?

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.Variable: A variable is a symbol that doesn't have a fixed value.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

We have the Expression:

(x + 4y + z) (x - 7y).

Step 1 :

x (x-7y) + 4y(x- 7y) + z (x- 4y)

Step 2:

x² - 7yx + 4yx - 28y² + zx - 4zy

Step 3:

x² -28y² - 3yx + zx - 4zy
