3. What amount of money is necessary to be invested at 5% simple interest to yield $320 in interest after 4 years?

Simora [160]

Answer:

$Amount = \$1920$

Step-by-step explanation:

Given

$Interest =\$320$

$Rate = 5\%$

$Years = 4$

Required

Determine the invested amount

First, we need to determine the Principal

This is calculated as:

$Interest = Principal * Rate * Time$

Solve for Principal

$Principal = \frac{Interest}{Rate * Time}$

$Principal = \frac{\$320}{0.05 * 4}$

$Principal = \frac{\$320}{0.2}$

$Principal = \$1600$

Add the principal to the interest

$Amount = Principal + Interest$

$Amount = \$1600 + \$320$

$Amount = \$1920$

How are we supposed to solve this question!?

VashaNatasha [74]

Answer:

use pythagorean's theorem; x=6

Step-by-step explanation:

a^2 + b^2 = c^2

a=length; b(x)=height; c= hypotenuse (longest side)

8^2 + b^2 = 10^2

64 + b^2 = 100 (subtract 64 from each side)

b^2= 36

6 x 6 = 36 so b=6

x=6

If a right triangle has a hypotenuse of length 100 units and one leg of length 60 units, what is the length of the other leg?

bixtya [17]

For this, we will be using the pythagorean theorem, which is $leg^2+leg^2=hypotenuse^2$ . Since we have the hypotenuse and one of the legs, we can solve for the other leg. Our equation will look like this: $x^2+60^2=100^2$

Firstly, solve the exponents: $x^2+3600=10000$

Next, subtract 3600 on both sides: $x^2=6400$

Next, square root both sides, and your answer will be x = 80 units
