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.
Should be %50 because half of all numbers are even and half are odd (don’t quote me on that though)
The answer would be A. 3. This is because you set both measurements equal.
(4x+9)=21
-9. -9
4x=12
X=3
Answer:
A = P(1 + r/100)^n
A = 1000 x (1.08)^n
Step-by-step explanation:
n is the number of years, p is the principal, A is the amount.
The lamp is appreciating (increasing in value) so every year, its value is 1.08 times its value the year before.
Use the first equation to be more general, use the second equation if there isn't anything below asking you to input numbers into the equation.
Probably just use the first one.
