Answer : $22.50
Explanation: .30•25=7.5 30-7.5=22.5
How many males and how many females would there be if the total enrollment is 15000?
Ratio is
90 males 15000 - x
------------- = ---------------
125 fem x
Then 90x = 1875000 - 125x, or 215x = 1875000
x = approx 8720 females
and 15000-8720, or 6279 males
If every male finds a dance partner, that would leave (8720-6279) females, or 2440, without dance partners. ;(
Check: is the male:female ratio near 90:125?
Is 6279:8720 approx equal to 90:125?
Yes. 0.72 (approx) = 0.72 (approx).
A ball is at it maximum height when its velocity is zero. y = 4+30t - 16t^2 is the formula, where
V = V(0) -32t
0 = 30- 32t
t = 15/16 seconds when its velocity is zero.
It is not at its maximum height but is falling.
82 I think that’s the answer because that’s my opinion if it’s wrong I don’t know what to tell you
Answer:
6
Step-by-step explanation:
This looks like a linear function.
From the first two points, we get the equation to be y=2x-1.
So to find n, 11=2n-1.
12=2n
n=6
