The distance from the top of the mirror to the ceiling once the mirror is hung on the wall is 21 inches
The dimension of the mirror is given as:


From the center of the mirror to the floor of the wall, the distance is:

So, the distance to the top of the mirror will be:

Substitute 24 for height


Convert feet to inches



The distance from the top of the mirror to the ceiling is the difference between the height of the wall and 75 inches.
So, we have:

Convert feet to inches



Hence, the distance is 21 inches

Answer:
48 members
Step-by-step explanation:
Add the numbers in the ratio: 4+4=8
Divide: 24boys/4=6
Multiply: 6*8=48
Now we know there are 48 people. Take it a step forward..how many girls?
EASY!
4*6=24 girls
We know this works because 24+24=48
*Note: the 4's come from the ratio*
You would have to move terms which will bring you to 14.4 x - 19.2 = 19.2 - 4.8x the you would combine like terms then you would get 19.2x= 38.4 then you divide both sides by 19.2 and get 2 as your answer.
