Answer:
216= 7/8 x L -8
Step-by-step explanation:
Given that,
One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder
The first cylinder’s volume is 216 centimeter cubed
From given,
Let "x" be the volume of second cylinder
Therefore,
Volume of first cylinder = 7/8 of the volume of a second cylinder - 8
Thus the volume of second cylinder is 256 centimeter cubed
V1 - velocity first train
v2 - velocity second train
v2 > v1
v2 - v1 = 17 mph
We know, that:
![s_1+s_2=210 \ [miles] \\ \\ t_1=t_2=2h](https://tex.z-dn.net/?f=s_1%2Bs_2%3D210%20%5C%20%5Bmiles%5D%20%5C%5C%20%5C%5C%20t_1%3Dt_2%3D2h)
So:

NOw we've got simple system of equations:
![+\begin{cases} v_2-v_1=17 \\ v_2+v_1=105\end{cases} \\ \\ 2v_2=122 \qquad /:2 \\ \\ v_2=61 \qquad [mph] \\ \\ v_2-v_1=17 \\ \\ 61-v_1=17 \\ \\ v_1=44](https://tex.z-dn.net/?f=%2B%5Cbegin%7Bcases%7D%20v_2-v_1%3D17%20%5C%5C%20v_2%2Bv_1%3D105%5Cend%7Bcases%7D%20%5C%5C%20%5C%5C%202v_2%3D122%20%5Cqquad%20%2F%3A2%20%5C%5C%20%5C%5C%20v_2%3D61%20%5Cqquad%20%5Bmph%5D%20%5C%5C%20%5C%5C%20v_2-v_1%3D17%20%5C%5C%20%5C%5C%2061-v_1%3D17%20%5C%5C%20%5C%5C%20v_1%3D44)
Velocities of these trains are 61mph and 44mph
The distance of 1 to -13 is 14.
Five sixths of this is (.8333*14), which equals 11.6667.

Answer:
40%
Step-by-step explanation:
20/50 is the amount of apples that are green/not red. 20÷50=0.4, which is equal to 40%
