Answer:
The answer is 792.
Step-by-step explanation:
I got the answer by first imagining how the 3d shape looks ike. Since one of the sqaure base length is 11 I found the base surface area by doing 11 times 11.My answer was 132. The since one of the slant length of the pyramid's triangle is 15, I did 11 times 15, my answer was 165. There are four triangles in the pyramid so I did 165 times 4, my answer was 660.
All the triangle surface area is 660 plus the sqaure surface are which is 132, that gave me my answer 792.
Answer:
1/2 of a gallon
Step-by-step explanation:
3 divided by 6 is 1/2
Lexi borrowed $425 and paid back $450, so the interest paid was $25 (subtract 450 and 425). Then divide the interest over the expression P*t = 425*0.5 = 212.5 to get 25/212.5 = 0.1176 approximately which converts to the annual interest rate of 11.76% (approximately).
If you want to use a formula, then,
i = P*r*t
25 = 425*r*0.5 <---- t = 0.5 to represent half a year
25 = 4250.5*r
25 = 212.5*r
212.5*r = 25
r = 25/212.5
r = 0.1176
r = 11.76%
