Answer:
x = 12
Step-by-step explanation:
I am unable to decipher what "x = 9/36 x/48" means.
I'll assume that the question is to find a value of x such that:
x/48 = 9/36
If so, cross multiply:
36x = (48*9)
36x = 432
x = 12
Answer:
approximately 1.58 seconds
Step-by-step explanation:
Set the function h(t)= -16t^2 + 40 = to 0 (the height above the ground when the ball hits). Then solve h(t)= -16t^2 + 40 = 0 for time (t):
-16t^2 + 40 = 0 becomes 16t^2 = 40. Solving for t^2: t^2 = 40/16 = 5/2.
Finally, we take the square root of this last result to determine t:
t = sqrt(10/4) = (1/2)sqrt(10)
The car hits the ground after (1/2)sqrt(10) seconds, or approximately 1.58 seconds.

The simplified ratio would be 8 girls and 9 boys
5 and a half hours.
600-250 for the first two hours and it leaves her 350 for additional hours. divide 350 by 50 and you get 7. so she can get 7 extra half hours which is 3.5 hours.
so 2+3.5 is 5.5
