Answer:

7/19 in.

Step-by-step explanation:

Use a proportion. Let x equal the unknown model length.

model/real = (14 in.)/(38 ft) = x/(1 ft)

(14 in.)/(38 ft) = x/(1 ft)

Cross multiply.

38 ft * x = 1 ft * 14 in.

Divide both sides by ft.

38x = 14 in.

Divide both sides by 38.

x = (14 in.)/(38)

x = 7/19 in.

Devin owes $26,000 in students loans for college. The interest rate is 8.75% and the loan will be paid off over 15 years. How mu
Nonamiya [84]

Using simple interest, it is found that Devin will pay $60,125 altogether.

The amount paid in <u>simple interest</u> is:

A = P(1 + rt)

In which:

  • P is the principal.
  • r is the interest rate, as a decimal.
  • t is the time, in years.

In this problem:

  • Owes $26,000 in student loans, thus P = 26000
  • Interest rate of 8.75%, thus r = 0.0875
  • Paid off in 15 years, thus t = 15.

The amount he will pay is of:

A = P(1 + rt)

A = 26000[1 + 0.0875(15)]

A = 60125

Devin will pay $60,125 altogether.

Find the measure of each angle (in degrees) of
d1i1m1o1n [39]

Answer:

∠A = 88°

∠B = 92°

∠C = 88°

∠D = 92°

Step-by-step explanation:

∠A + ∠B = 180°

(2x + 4) + (3x - 34) = 180

reduce:

5x - 30 = 180

5x = 210

x = 42

∠A = 2(42) + 4 = 88°

∠B = 3(42) -34 = 92°

∠C = ∠A = 88°

∠D = ∠B = 92°
