Jeremiah opened a savings account with a one-time deposit of $500. His savings account will pay a 5% simple interest per year. His brother, Brian, opened another savings account with a one-time deposit of $200. Brian’s savings account will pay 3% compounded annually. Who would earn more interest, to the nearest dollar, in 2 years?

Answers

Answer:

jeremiah would earn more interest to the nearest dollar in 2 years

Step-by-step explanation:

It is found that jeremiah would earn more interest to the nearest dollar in 2 years.

How to calculate simple interest amount?

If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:

[tex]I = \dfrac{P \times R \times T}{100}[/tex]

Given that Jeremiah opened a savings account with a one-time deposit of $500. Rate of 5% simple interest per year.

I = 500 x 5 x 1/100

I = 25

For 2 year it would be 50 dollars.

Also, Brian, opened another savings account with a one-time deposit of $200. Rate of 3%

[tex]a = p(1 + \dfrac{r}{n})^{nt}\\a = 200(1 + \dfrac{3}{2})^{4}[/tex]

a = 12.35

Hence, It is found that jeremiah would earn more interest to the nearest dollar in 2 years.

Find the area and perimeter of trapezium.

Answers

Answer:

Area: 9

Perimeter: 22

Step-by-step explanation:

Area = ½ * (a+ b) * h = ½ * (4 + 5) * 2 = ½ * 9 * 2 = 9.

Perimeter = a + b + c + d = 4+5+6+7 = 22.

Answer:

P (Perimeter) = 21

A (Area) = 33

Step-by-step explanation:

P = a + b + c + d

A = (a + b/2) * h (or, rather, AREA = ONE-HALF BASE 1 + BASE 2 TIMES HEIGHT)
