Answer:

7 m

Step-by-step explanation:

We see that the the side measuring 6 m corresponds to the side measuring 18 m. Also, the side measuring 8 m corresponds to the side measuring 24 m. In each case, the corresponding side of the right triangle is 3 times larger than the side of the left triangle. We divide 21 m by 3 to get 7 m.

A newborn child receives a $20,000 gift toward college education from her grandparents. How much will the 20,000 be worth in 17
Alexus [3.1K]

Answer:

The amount the $20.000 will be worth in 17  years at compound interest is $65068.443

Step-by-step explanation:

Here we have the Principal, P = $20,000.00

The annual interest rate, r = 7% = 0.07

Time , t = 17 years

Number of compounding period per year, m = quarterly = 4

The compound interest can be found from the following formula;

Amount, \ A = P \left (1 + \frac{1}{r}  \right )^{mt}

Therefore, by plugging the values of the equation parameters, we have;

Amount, \ A = 20000 \left (1 + \frac{0.07}{4}  \right )^{4 \times 17} = \$  65068.443

Therefore, the amount the $20.000 will be worth in 17  years at compound interest = $65068.443.
