Answer:
D
Step-by-step explanation:
Hexa means six, so a hexahedron is a figure with six faces. Therefore, choice D is the correct answer.
Answer:
Step-by-step explanation:
Use synthetic division to answer this. If the remainder is zero, then we can safely assume the divisor (x + 7) is a factor of the polynomial f(x)= x^3-3x^2+2x-8.
We use -7 as the divisor in synth. div. This comes from the factor (x + 7):
-7 / 1 3 2 -8
-7 28 -210
-------------------------
1 -4 30 -218
Here, the remainder is -218, not zero, so no, (x+7) is not a factor of f(x)= x^3-3x^2+2x-8.
Answer:
Hello
Step-by-step explanation:
the Pythagoras Theorem proves this
We want to know how much is the price per pound (or unit rate) of ground beef, given that we know the price for Elliot's purchase. We will see that each pound costs $4.75
So we know that (3 + 2/5) lb of ground beef costs $16.15, the cost of a single pound will be given by the quotient between the total cost and the amount purchased, then we need to solve:
![P =\frac{ \$ 16.15}{(3 + 2/5)lb}](https://tex.z-dn.net/?f=P%20%3D%5Cfrac%7B%20%5C%24%2016.15%7D%7B%283%20%2B%202%2F5%29lb%7D)
We can rewrite the denominator as:
(3 + 2/5)lb = (15/5 + 2/5)lb = (17/5) lb
Replacing that we get:
![P =\frac{ \$ 16.15}{(17/5)lb} = \frac{ \$ 16.15*5}{17lb} = \$4.75 \ per \ lb](https://tex.z-dn.net/?f=P%20%3D%5Cfrac%7B%20%5C%24%2016.15%7D%7B%2817%2F5%29lb%7D%20%3D%20%5Cfrac%7B%20%5C%24%2016.15%2A5%7D%7B17lb%7D%20%3D%20%5C%244.75%20%20%20%5C%20per%20%20%5C%20lb)
So each pound of ground beef costs $4.75
