You take 45 and divide it by 15 and you get, 3 cubic feet
Answer:
The domain is the set of all whole numbers greater than or equal to 0 and less than or equal to 7.
Step-by-step explanation:
let x be the number of nail polishes that Taylor purchases .
Therefore the amount spent by Taylor on nail polishes will be f(x) = 3.95\times x
since Taylor has only 30 dollars to spend on nail polishes.
f(x) \leq 30 dollars
therefore 3.95\times x \leq 30
x \leq 7.594
since x is an whole number x = 7
Therefore the domain is the set of all whole numbers greater than or equal to 0 and less than or equal to 7.
I think the 6 by 6 and the 3 by 3 is similar to the 5 by 5 figure.
Hope this helps!
Answer:
-5x - 16y - 24z
Step-by-step explanation:
5x - 2y - 6z - 10x - 14y - 18z
5x - 10x - 2y - 14y - 6z - 18z
-5x - 16y - 24z
So you do 79+89+90=258 then you take 258/3=9.3 so you would get a 93% test average
Hope this helps
