A triangle has legs that are 7in and 24in long. How long is the hypothenuse?
SashulF [63]

Answer: 25 in

Step-by-step explanation:

<u>Due to the use of the term "hypotenuse" I will assume the triangle is a right triangle.</u>

According to pythagorean theorem, 7²+24²=(hypotenuse)²

49+24²= (hypotenuse)²

49+576= (hypotenuse)²

625 = (hypotenuse)²

25 = hypotenuse

Burt's grandparents started a savings account for him when he was born. They invested
SashulF [63]

Answer:

4594.76 USD will be in the account on Burt's 18th birthday.

Step-by-step explanation:

Since interest rate is constant in time, we can use the definition of composite interest to determine how much money will be on Burt's 18th birthday, that is:

C = C_{o}\cdot \left(1+\frac{r}{100} \right)^{t} (1)

Where:

C_{o} - Initial amount, measured in US dollars.

C - Current amount, measured in US dollars.

r - Annual interest rate, measured in percentage.

t - Time, measured in years.

If we know that C_{o} = 1250\,USD, r = 7.5 and t = 18, then the money in the savings account on Burt's 18th birthday is:

C = (1250\,USD)\cdot \left(1+\frac{7.5}{100} \right)^{18}

C = 4594.76\,USD

4594.76 USD will be in the account on Burt's 18th birthday.
