Answer:
192 cubes.
Step-by-step explanation:
The volume of each cube = (side)³ = (1/4)³ = 1/64 units
³
Next is to find how many cubes are needed to fill the prism.
The number of cubes that will fill the prism :
Vol. of prism / Vol. of cube = 3 / 
=192 cubes.
Therefore, it takes 192 cubes to fill the prism.
The answer is D. "x=-15 or 15."
You can solve this by adding seven on both sides.
|x|-7=8
+7 +7
------------
|x|=15
Therefore, x is either equal to 15 or -15.
Answer:
The second one is right I believe; 2x<x+22
Step-by-step explanation:
Answer:
no
Step-by-step explanation:
Using substitution, subs in the points given
(15) = 5(4) - 2
15 = 20 - 2
Because the 2 sides are NOT equal the line would not pass through the point
Answer:
90
Step-by-step explanation:
There are 10 people who can be picked for the first position, which leaves 9 people who can be picked for the second position.
10 × 9 = 90
You can also use permutations.
₁₀P₂ = 90
