Answer:
927 cubic inches
Step-by-step explanation:
The area of the octagonal base is ...
A = (1/2)Pa
where P is the perimeter, and 'a' is the apothem. Using the given numbers, the base area is ...
A = (1/2)(8·4)(4.83) = 77.28 . . . square inches
The volume of the prism is given by ...
V = Bh
where B represents the area of the base, and h is the height.
V = (77.28 in^2)(12 in) = 927.36 in^3
The volume of the prism is about 927 cubic inches.

Ella is baking cookies to put in packages for a fundraiser. Ella has made 86 chocolate chip cookies and 42 sugar cookies.
Ella wants to create identical packages of cookies to sell, and she must use all of the cookies.
What is the greatest number of identical packages that Ella can make?


Multiply the denominators to make it one fraction.
Now for the numerator, you multiply the numerator of the the 1st fraction with the second fractions denominator. Then Multiply the 1st fractions denominator with the 2nd fractions numerator. Now with those two numbers you Subtract it. Whatever number you get is the numerator. So there is the fraction. You would just simplify it. (IF you want to add fractions instead of subtracting the numerators, you add the numerators. Like instead of 68-12 you would do 68+12

We will create a proportional relationship to find x.

The missing side is <em>D. x = 5</em>.
She bought N pencils last month for 288, as the amount is in pennies. This month she bought N+12 for 720.
288/N = 720 / (N+12)
288(N+12) = 720N
288N + 3456 = 720N
3456 = 720N - 288N
3456=432N
N=8
She bought 8 pencils last month for 288, which is 36 cents each. And she bought 20 pencils this month for 720 which is 36 cents each. Hope this helped :)
The answer is b because the square root of 7 is 2.6.
