Perry borrows $350 at a simple interest rate of 4.5%. Perry pays back the loan in 30 months. How much interest does Perry pay on

Nitella [24]

Answer: the interest on the loan is $39.38

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

From the information given,

P = $350

R = 4.5%

There are 12 months in a year. Converting 30 months into years, it becomes

30/12 = 2.5. so

T = 2.5 years

Therefore

I = (350 × 4.5 × 2.5)/100

I = $39.38

Tan39= x/68<br> Plz help. Will give brainliet

lesya [120]

Answer:

$\huge\boxed{x \approx 55}$

Step-by-step explanation:

We need to note that this is an equation, in which we can solve for x.

$tan(39) = \frac{x}{68}$

We can use a calculator to find the tangent of 39 - we type 39 into the calculator then press the "TAN" button to find it's tangent. We find that to be around 0.81.

We now have the formula simplified down to $0.81 = \frac{x}{68}$ . To solve for x, we want to isolate it on one side, so we can multiply both sides by 68 to get rid of the fraction.
