How do you solve this? <br>Y x 49/36=7/12

Triss [41]

Divide both sides by 49/36 to get y by itself:

$\frac{7}{12} \div \frac{49}{36}$

$\frac{7}{12} \times \frac{36}{49} = \frac{254}{588}$

Simplify this fraction:

$\frac{254}{588} \div \frac{2}{2} = \frac{127}{294}$

Now you have your answer:

$y = \frac{127}{294}$

Step-by-step explanation:

Incomplete question [See comment for complete question]

Given

Shape: Cone

$r = 3$ -- radius

$h = 7$ --- height

$Rate = 14in^3/min$

Required

Time to pass out all liquid

First, calculate the volume of the cone.

This is calculated as:

$V = \frac{1}{3} \pi r^2h$

This gives:

$V = \frac{1}{3} * 3.14 * 3^2 * 7$

$V = \frac{1}{3} * 197.82$

$V = 65.94in^3$

To calculate the time, we make use of the following rate formula.

$Rate = \frac{Volume}{Time}$

Make Time the subject

$Time= \frac{Volume}{Rate }$

This gives:

$Time= \frac{65.94in^3}{14in^3/min}$

$Time= \frac{65.94in^3}{14in^3}min$

Cancel out the units

$Time= \frac{65.94}{14} min$

$Time= 4.71 min\\$
