Rebecca bought candy boxes in the shape of a square pyramid to use for party favors. The side length of each box is 3.6 inches, and the height is 4 inches. Rebecca wants to fill each box with 20 pieces of candy. If each piece of candy is 0.8 in.³, will Rebecca be able to fit 20 pieces of candy into each candy box? No, because the volume of the candy box is 17.28 in ³, so it will hold about 17 pieces of candy.

Yes, because the volume of the candy box is 51.84 in ³, so it will hold about 64 pieces of candy.

Yes, because the volume of the candy box is 17.28 in ³, so it will hold about 21 pieces of candy.

No, because the volume of the candy box is 8.64 in ³, so it will hold about 10 pieces of candy.

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.

answer is  

a.

5.56

hope you get this right.
