Using compound interest, it is found that he must deposit $56,389.
Compound interest:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
- t is the time in years for which the money is invested or borrowed.
In this problem:
- Hopes to have $80,000 in 20 years, thus
. - Interest rate of 1.75%, thus
. - Compounding monthly, thus
- The investment is of P, for which we have to solve.
Then:
He must deposit $56,389.

Yes, because slope is the steepness of a line. if the steepness of those two lines are the same, you will have to expand the x-axis (the length of the first ramp).
Answer:
10
Step-by-step explanation:
The ration is 1 : 4, so since the larger square has an area of 400, the smaller square has an area of 100. This makes the ratio 100 : 400, which is equal to 1 : 4 (all I did was multiple both sides of the ration by 100). Then, because a square has equal sides, I found the square root of 100. 10 is the square root of 100, because 10 x 10 = 100, so each side is 10 inches long.
