First you divide the smaller number by the larger number, to see how many of that number goes into the other:
45/50 = 0.9

The you times it by 100 to get the percentage:
0.9*100 = 90%

Hope this helps! :)

M is directly proportional to r2.when r=2,m=14.Work out the value of r when m =224
DENIUS [597]

Answer:

r=8

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form  y=kx

In this problem

Let

y=m

x=r^{2}

substitute

m=kr^{2}

<u>Find the value of k</u>

For r=2, m=14

14=k(2^{2})

14=4k

k=14/4 ----> constant of proportionality

the equation is equal to

m=(14/4)r^{2}

Find the value of r when m=224

substitute in the equation and solve for r

224=(14/4)r^{2}

r^{2}=224*4/14

r^{2}=64

r=8
