So we can take the volume of a cube formula and set it equal to the volume that we actually know: 64 centimeters cubed. So in order to find the length of the edge, which is a side, we need to cube root both sides of this equation. On the left-hand side, the cube root cancels all the cube.
X^2+7x-7x-49
Simplified = x^2-49
Divide the price by the quantity to see what's a better deal.
4.25 / 5 = 0.85
So, for each apple it costs 85 cents.
6.56 / 8 = 0.82
So, for each apple it costs 82 cents.
So, the $6.56 for 8 pounds of apples is the better deal.
Answer:
43 feet
Step-by-step explanation:
How far is referring to the distance between the two numbers given.
In general, the distance between two numbers, a and b,
is given by |b-a| .
You have that you are finding the distance between -45.5 ft and -88.5 ft.
So the distance between those numbers is given by:
|-45.5-(-88.5)|
|-45.5+88.5|
|88.5-45.5|
|43.0|
|43|
43 (Since the number inside the | | has a distance of 43 from 0)
The distance between -45.5 ft and -88.5 ft is 43 ft.
