Answer:
130.8
Step-by-step explanation:
I did the quiz
4(2.4)(2)+43
(9.6)(2)+43
19.2+43
62.2
the value of 4n x 2 + 43, when n=2.4, is 62.2
Answer:
Maximum Volume = 29,659.5 cubic inches
Step-by-step explanation:
We can write the perimeter as 2*(x+h) and this is equal to 117
So

The volume is 
Plugging the expression for h, we have:

The max volume can be found when this differentiated is equal to 0, or dV/dx=0

x can't be 0, so we take x = 39
and thus h=58.5-x = 58.5-39=19.5
Max Volume = 
Well there is no following but I can tell you that the probability of getting tails is 48/100 which they probably want simplified which jusst means divide both numerator and denominator(top and bottom numbers) by Z (whatever number works) untill it can't be a whole number anymore(a number without a decimal number), simply put, divide top and bottom numbers by the GCM(Greatest Common Multiple) which in this case is 4. 48/4=12, 100/4=25 48/100=12/25 you can't simplify that any more so the answer is 12/25
The Answer Is 12/25 or 48%
Hope This Helps.
