If you invested $500 at 5% simple interest for 2 years, how much interest do you earn? Show work and answer in

givi [52]

Answer:

$50

$30.88

I will invest in simple interest as the interest there is more.

Step-by-step explanation:

If I invested $500 at 5% simple interest for 2 years, then the interest that I will get will be given by the formula

$I = P \times \frac{rt}{100}$ , where P is the invested principal, r is the APR and t is the time in years.

So, in our case, $I = 500 \times \frac{5 \times 2}{100} = 50$ dollars. (Answer)

Now, if I invest $500 at 3% compound interest compounded monthly for 2 years.

Now, using the formula of compound interest we have

$I = P(1 + \frac{r}{n \times 100} )^{tn} - P$ , where r is the APR and n is the number of times in a year the principal is compounded.

In our case, $I = 500(1 + \frac{3}{12 \times 100} )^{2 \times 12} - 500 = 30.88$ dollars. (Answer)

Therefore, I will invest in simple interest as the interest there is more. (Answer)

Jessica is planting a garden. It has the shape of a right triangle. She wants 2 plants for each square yard of area. How many pl

attashe74 [19]

Answer:

42 plants

Step-by-step explanation:

Dimensions are missing.

Suppose a right triangle has a base of length 7yards and a height of 24 yards.

As you know, Area of triangle can be determined by

Area of triangle 'A'= 1/2 x b x h = 1/2 x 7 x 24

A= 84 yards²

Now she wants 2 plants for each square yard of area

therefore, if the area is 84 yards²:

number of plants are 84/2=> 42 plants

Thus, She wants 42 plants in the garden
