7 men= 5 women
380 men= x women
=> 7x = 5 . 380
7x = 1900
x= 1900/7
x= 271,4
wich means 271 women

Or
Men - 420 = Women 

Take (Men) / (Women) for each proportion... 

7 / 5 = M / (M - 380) 

Cross multiply: 

5 M = 7 (M - 380) 
5 M = 7 M - 1900 
-2 M = - 1900
M = 950

W = M - 380
W = 950 - 380 = 570
M + W = total enrolled
950 + 570 = 1520

The ratio of jumps to falls for ice skater Rhonda is 4 falls to every 15 jumps. At this rate, how many times will she not fall i

Inessa05 [86]

Answer:

Rhonda will not fall 264 times in 360 jumps.

Solution:

Given, The ratio of jumps to falls for ice skater Rhonda is 4 falls to every 15 jumps.

We have to find At this rate, how many times will she not fall in 360 jumps.

Now,

For 15 jumps → 4 falls

For 360 jumps → n falls

Now apply Chris cross method,

$15 \times n=360 \times 4 \rightarrow n=\frac{360 \times 4}{15}=24 \times 4=96$

So, she falls 96 times in 360 jumps.

Then, number of times she will not fall = 360 jumps – 96 falls = 264 times.

Hence, Rhonda will not fall 264 times in 360 jumps.
