a= -5t+30
5t=30-a
t=30-a/5
5 <30-a/5 <7
5.5 <30-a <7.5
25 <30-a <35
25-30 <30-a-30 <35-30
-5 < -a <5
5>a>-5

Answer:
726 feet
Step-by-step explanation:
Object height and shadow length are proportional, so you have ...
(object height)/(shadow length) = (18 ft)/(72 ft) = (dam height)/(2904 ft)
Then the dam height is ...
dam height = (2904 ft)(18/72) = 726 ft
Hoover Dam is 726 feet high.
The answer is C, First you must find the length of the diagonal gravel path and you can use Pythagorean Theorem to do this. 24^2+32^2=c^2 and solve for c which will get you 40 feet. Now, solve for the area of the path by multiplying 40*2 (2 feet wide) which will get you an area of 80 square feet. Multiply 80 by 3.5 and then the answer is $280. Hope this helped you :)
