You can put this solution on YOUR website! The ratio of females to males in a school band is 7 to 4 If three femails and twelve males are absent from practice, the ratio of females to males is 5 to 2 How many members of the band attend practice?
------------
f:m = 7:4 = 7x:4x
EQUATION:
[7x-3]/[4x-12] = 5/2
14x-6 = 20x-60
6x=54
x=9
If the last question refers to number attending when the 3 females and
12 males are missing the answer is:
females: 7x-3=7*9-3=60
males : 4x-12=4*9-12=24
For a total of 84
--------------------------
If all the millimeter cubes in one cubic meter are placed one on top of another to make a pole, what will be the height of the pole?
1,000 millimeters in a meter
one cubic meter is 1meter by 1meter by 1 meter
Number of cubic millimeters is (1000*1000*1000)mm
That is the height of the pole.
Cheers,
