Answer:

80 distributions of the three scholarship are possible.

Step-by-step explanation:

Given that 4 freshman, 5 sophomore, and 4 juniors have been nominated to receive a scholarship of $ 500, $ 250, and $ 100, to determine how many distributions of the three scholarship are possible if one scholarship is to be awarded to someone from each class you must perform the following calculation:

4 x 5 x 4 = X

20 x 4 = X

80 = X

Therefore, 80 distributions of the three scholarship are possible.

Please explain and answer

krek1111 [17]

Step-by-step explanation:

$v \: = \: \pi \: {r}^{2} \times \frac{h}{3}$

rearrange to get

$48\pi \: = \: \pi {r}^{2} \times \frac{9}{3}$

remove pi from both sides

$48 \: = {r}^{2} \: \times 3$

$\frac{48}{3} = {r}^{2}$

$16 = {r}^{2}$

$r = \sqrt{16}$

$r = 4$

gladu [14]

N=8+d
10d+5n=145
divide 2nd equaiton by 5 to make nicer and easier
2d+n=29

subsitute 8+d for n in 2nd equation
2d+8+d=29
3d+8=29
minus 8 both sides
3d=21
divide by 3
d=7
sub back
n=8+d
n=8+7
n=15

15 nickles and 7 dimes
