Is there a specific question that you want to ask?
Answer:
A. 39,000.
Step-by-step explanation:
Volume of the lower prism = 30^3= 27,000
Volume of the pyramid = 1/3 area of the base * height
= 1/3 * 900 * 40
= 1200
Volume of the whole solid = 27000 + 12000
= 39,000,
Answer:
c. infinite solutions
Step-by-step explanation:
y = 10x + 2
This is a line. A line has infinite points
Therefore this has infinite solutions
4a-8=28
add 8 to both sides to start to isolate the variable (a)
-8+8 cancels each other out
28+8=36
4a=36
to completely isolate the variable divide both sides by 4
4a÷4=a
36÷4=9
a=9
Answer:
4
Step-by-step explanation:
d - 9 = -5
Add 9 to -5, and you will get 4.
4 - 9 = -5
