We have an equation: 3/?= 1/5
Cross multiply:
1*?= 3*5
⇒ ?= 3*5= 15

<span>To find out how much wax is needed for the candles we need to figure out the volume of each candle. We know radius r=0.5 inches and height h=3 inches of the smallest candle and we know that the middle candle has r2=2r=1 inch and h2=2h=6 inches and the biggest candle has r3=3r=1.5 inches and h3=3h=9 inches. So now we need the formula for volume: V=pi*r^2*h and we simply plug in the numbers. First candle is V=3.14*(0.5^2)*3=2.355 inches^3. Middle candle: V2=3.14*(1^2)*6=18.84 inches^3. Biggest candle: V3=3.14*(1.5^2)*9=63.585 inches^3. So overall wax needed to create all three candles is V+V2+V3=2.355 inches^3 + 18.84 inches^3 + 63.585 inches^3=84.78 inches^3.</span>
Given :
Cost of each ball , $3.
Cost of each bat , $35 .
Total money spend , $131 .
She buys twice as many balls as bats.
Tax , $8 .
To Find :
The number of bats she buys .
Solution :
Let , x represent the number of bats she buys.
So , number of balls she buys is 2x .
![35x+3(2x)+8=131\\\\35x+6x=123\\\\41x=123\\\\x=3](https://tex.z-dn.net/?f=35x%2B3%282x%29%2B8%3D131%5C%5C%5C%5C35x%2B6x%3D123%5C%5C%5C%5C41x%3D123%5C%5C%5C%5Cx%3D3)
Therefore , number of bats she buys is 3 .
Hence , this is the required solution .
M=3/1
