1/2.54 = 90/x
Cross multiply
(1)x = (2.54)(90)
x would equal 228.6
The answer would be 90 in/ 228.6 cm.

Answer:2.8
Step-by-step explanation:add 3.5 to the 10.5 which equals 14 then you divide 5 by 14 to get the y alone and it equals 2.8
Answer with explanation:
Given : Number of men = 4
Number of women = 6
Total people = ![6+4=10](https://tex.z-dn.net/?f=6%2B4%3D10)
Total number of ways to make a committee of five people from 10 persons :-
![^{10}C_{4}=\dfrac{10!}{4!(10-4)!}=210](https://tex.z-dn.net/?f=%5E%7B10%7DC_%7B4%7D%3D%5Cdfrac%7B10%21%7D%7B4%21%2810-4%29%21%7D%3D210)
a) Number of ways to make committee that has exactly four women :
![^6C_4\times ^4C_1=\dfrac{6!}{4!(6-4)!}\times4=60](https://tex.z-dn.net/?f=%5E6C_4%5Ctimes%20%5E4C_1%3D%5Cdfrac%7B6%21%7D%7B4%21%286-4%29%21%7D%5Ctimes4%3D60)
The probability that committee has exactly four women :
![\dfrac{60}{210}=\dfrac{2}{7}](https://tex.z-dn.net/?f=%5Cdfrac%7B60%7D%7B210%7D%3D%5Cdfrac%7B2%7D%7B7%7D)
b) Number of ways to make committee that has at-least four women :
![^6C_4\times ^4C_1+^6C_5=\dfrac{6!}{4!(6-4)!}\times4+6=66](https://tex.z-dn.net/?f=%5E6C_4%5Ctimes%20%5E4C_1%2B%5E6C_5%3D%5Cdfrac%7B6%21%7D%7B4%21%286-4%29%21%7D%5Ctimes4%2B6%3D66)
The probability that committee at-least four women :
![\dfrac{66}{210}=\dfrac{22}{70}](https://tex.z-dn.net/?f=%5Cdfrac%7B66%7D%7B210%7D%3D%5Cdfrac%7B22%7D%7B70%7D)
c) Number of ways that committee has more than 4 women :-
![^6C_5\times^4C_0=6](https://tex.z-dn.net/?f=%5E6C_5%5Ctimes%5E4C_0%3D6)
The probability that committee has more than 4 women :-
![\dfrac{6}{210}](https://tex.z-dn.net/?f=%5Cdfrac%7B6%7D%7B210%7D)
Now, the probability that committee has at most four women :-
![1-\dfrac{6}{210}=\dfrac{204}{210}=\dfrac{102}{105}](https://tex.z-dn.net/?f=1-%5Cdfrac%7B6%7D%7B210%7D%3D%5Cdfrac%7B204%7D%7B210%7D%3D%5Cdfrac%7B102%7D%7B105%7D)
18-7=11
11x2=22
