Answer: 12
Step-by-step explanation: V of prism = S of triangle*Height of prism
height of prism is 30
S of triangle = a/2*<em>h</em>( a =18 cm)
3240=30*(18/2)*<em>h</em>
<em>h</em>=3240/(9*30)=12
The answer is 2 because distributive property means that you can multiply with the numbers inside of the parentheses and still get the same answer
y-3-(-12)≥0
y ≥ -9
y + 9.000 ≥ 0
y ≥ -9
I hope this helps!
Answer:
x = 20
Step-by-step explanation:
There is a right angle which is 90 degrees. Part of the angle is 30 degrees, so the other measure is 60 degrees, which is the 3x.
Make an equation.
3x = 60
Divide both sides by 3
3x/3 = 60/3
x = 20
Answer:
11 13/15
Step-by-step explanation:
-3 2/3+b = 8 1/5
Add 3 2/3 to each side
-3 2/3 + 3 2/3+b = 8 1/5+ 3 2/3
b = 8 1/5 + 3 2/3
We need to get a common denominator of 15
8 1/5 = 8 3/15
3 2/3 = 3 10/15
----------------
11 13/15
