Answer: 6 3/4
Step-by-step explanation:
1. Use proportion:
8:4.5=24:x
8x=24*4.5
x=3*4.5
x=13.5
2. Use proportion
8:4.5=4:x
x8=18
x=18/8
x=9/4
x=2.25
3. For 24 people you need 13,5
for 12 people you need :
24:13.5=12:x
x=13.5/2
x=6.75
The answer to this problem would be A
Answer:
-60 miles per hour
Step-by-step explanation:
x^3y^3 + 343
The way the sum of cubes works is by taking the roots of each term and applying the formula.
The sum of cubes is as follows:
a^3 + b^3 = (a + b)(a^2 - ab + b^2)
In this case, we would display it like this:
x^3y^3 + 343 = (xy + 7)(x^2y^2 - 7xy + 49)
13.5•18 = 243 inches squared
