Answer:
28
Step-by-step explanation:
24x1.10=28
The square root of 1 is 1, but the square root of 18 needs to be explored. 18 is 9*2, and 9 is a perfect square. So let's rewrite our original problem using that fact:
![\sqrt{ \frac{1}{18} } = \sqrt{ \frac{1}{9*2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%5Cfrac%7B1%7D%7B18%7D%20%7D%20%3D%20%5Csqrt%7B%20%5Cfrac%7B1%7D%7B9%2A2%7D%20%7D%20)
. We can pull out the square root of 1 as 1 and the square root of 9 as 3, leaving the 2 behind:
![\sqrt{ \frac{1}{9*2} } = \frac{1}{3} \sqrt{ \frac{1}{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%5Cfrac%7B1%7D%7B9%2A2%7D%20%7D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%5Csqrt%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20%20%20)
. And there you go!
Solution:
Total number of students=273
Let x students choose Tiger. Then we can write
Number of students who choose Bulldog ![=4x](https://tex.z-dn.net/?f=%3D4x)
Number of students who choose Lion ![=2x](https://tex.z-dn.net/?f=%3D2x)
So we can write
![x+2x+4x=273\\ \\ 7x=273\\ \\ x=39\\](https://tex.z-dn.net/?f=x%2B2x%2B4x%3D273%5C%5C%0A%5C%5C%0A7x%3D273%5C%5C%0A%5C%5C%0Ax%3D39%5C%5C)
Hence a total of 39*2=78 student choose Tiger.
