There will be 18 girls in a group of 16 boys.
you divide 72 by 16 and get 4.5.
then you divide 81 by 4.5 and get 18.
That is how you get 18 girls in a group of 16 boys.
Hope that helped.
The question is asking for the highest common factor (HCF)
1220 =
![2^{2}](https://tex.z-dn.net/?f=%202%5E%7B2%7D%20)
x 5 x 61
549 =
![3^{2}](https://tex.z-dn.net/?f=%203%5E%7B2%7D%20)
x 61
HCF = 61
Ans: 61

Answer:
Exponential decay since the base (0.765) of the exponential is greater than 0 but less than 1.
Simplify
-4x^4 + 6 -3x^2 - (11 - 6x^4)
Simplify brackets
-4x^4 + 6 - 3x^2 - 11 + 6x^4
Collect like terms
(-4x^4 + 6x^4) + (6 - 11) - 3x^2
Simplify
<u>2x^4 - 5 - 3x^2</u>
