Answer:
1.
Volume= 729cm^3
Height= 9cm^2
Area of Base= 81cm^2
2.
Volume=450m^3
Height= 3m^2
Area of Base=150m^2
3.
Volume= 480 cm^2
Area of base=75cm^2
Height= 8cm^2
4.
Volume =120in^3
Area of Base=20in^2
Height= 6in^2
Step-by-step explanation:
Volume = (length) Times (Width) Times (Height)
Area os base = (Length) Times (width)
Answer:
The answer is that you tutored for 4 hours.
Step-by-step explanation:
There are 6 total squares, so then you must divide 12 by the number of squares (6), to find the value of one square. Then, you would find that one square equals 2 hours, and since you have 2 squares that means that you tutored for 4 hours.

Answer:
Step-by-step explanation:
It seems this system of equations would be solved easier using the elimination method (the x and y values are lined up).
Multiply everything in the first equation by -2 (we want the 4x to be able to cancel out with a -4x).
Now line up the equations (they are already lined up - convenient) and add them from top to bottom.
The -4x and 4x are opposites, so they cancel out.
Adding 6y and 2y gives you 8y, and adding -12 and 4 gives you -8.
Divide both sides by 8.
Since you have the y-value you can substitute this in to the second (or first equation, it doesn't necessarily matter) equation.
Simplify.
Add 2 to both sides.
Divide both sides by 4.
The final answer is 
.
126.4 I guess.... How you wrote it is a tad confusing. Is the second set of numbers another question?
