Answer:
The total surface area is: 468 in^2 which agrees with answer a)
Step-by-step explanation:
The three lateral faces of the prism are rectangles, and the sums of their areas give:
12 * 10 + 9 * 10 + 15 * 10 = 360 in^2
The area of each triangular base (notice it is a right triangle) is given by:
9 * 12 / 2 = 54 in^2, so we add TWO of these to the three rectangular faces:
Total surface = 360 in^2 + 2 * 54 in^2 = 468 in^2
65.25 - 40.50 = How much longer the pool is than wide
= 24.75 longer
It is also or about 38%.
I=ptr
i=(3000)(1461)(3.5%)
i=153405
his cost will be $153 405 by 4 years
To find the correct fraction, multiply 6 by 3.
This gives you 18. Therefore the fraction is 18/3
Hope this helps!
Answer:
y=1/7.50x+40
Step-by-step explanation:
I doubled checked myself on desmos and it worked. You start at 40$ because you pay that no matter what. For each one they buy the price goes up by 7.50$.
