Suppose you deposit ​$ in a savings account that pays interest at an annual rate of ​%. If no money is added or withdrawn from the​ account, answer the following questions. a. How much will be in the account after ​years?
b. How much will be in the account after ​years?
c. How many years will it take for the account to contain ​$​?
d. How many years will it take for the account to contain ​$​?
a. After ​years, the amount in the account will be ​$

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

answer: 590

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
