In a survey, three out of four people preferred vanilla ice cream over chocolate. There are 120 people shopping at a grocery store. Use the survey to predict how many people in the grocery store would prefer vanilla ice cream?

90 people

Step-by-step explanation:

3/4 people preferred vanilla over chocolate.

This means that out of the 120 people coming to shop in the store, an estimated 3/4 prefer vanilla to chocolate.

Your answer should be the figure that represents 3/4 out of 120.

= 3/4 * 120

= 360 / 4

= 90 people

step-by-step explanation:

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)
