So let's say he was earring x before his raise. That means that:
x times 1.09 = 654 (1.09 represents 100% (this is the 1.0) of his original salary plus 9% (this is the .09) his raise.
So,
1.09x = 654; now divide both sides by 1.09 to isolate and solve for x, and you get x = $600.
Answer:
1. For a cube, volume = 
2. ![\sqrt[3]{volume}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bvolume%7D)
= edge
3. Volume of the cube = 216 so, the edge = ![\sqrt[3]{216}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B216%7D)
= 6
4. 1st blank = 6
2nd blank = 6
3rd blank = 216
4th blank = 216
5. 6 is the edge
6. As the room is a square and we have to find the side
Area = 121
Edge = ![\sqrt[2]{121}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B121%7D)
= 11

33.51 inches
Step by Step: (3.14*2^2)*(8/3)=33.51 inches
85 x 3 = 255
first 2 test grades were 81 and 86:
81 + 86 = 167
Need to find the 3rd to have exact average 85:
255 - 167 = 88
So her 3rd test needs to make 88 to make average of 85
Double check: 81 + 86 + 88 = 255 = 85 + 85 + 85
To do this i add them uo and easily subtract woth a hand held calculator
