Answer:
Median: 85
Mode: 85
Range: 20
Mean: 86
Step-by-step explanation:
We have 2 angles that are supplementary, so their sum equals 180⁰.
(4x - 10) + (7x - 8) =180
11x - 18 = 180
11x = 198
x = 18

The question is incomplete. The complete question is :
Cylinders A and B are similar. The length of the cylinder A is 4 mm and the length of cylinder B is 6 mm. The volume of cylinder A is 20mm3. Calculate the volume of cylinder B.
Answer:
67.5 ![mm^3](https://tex.z-dn.net/?f=mm%5E3)
Step-by-step explanation:
Given that :
Cylinder A and cylinder B are similar.
Let volume of cylinder A = 20 ![mm^3](https://tex.z-dn.net/?f=mm%5E3)
We know the volume of a cylinder is given by V = ![$\pi r^2 h$](https://tex.z-dn.net/?f=%24%5Cpi%20r%5E2%20h%24)
where, r is the radius of the cylinder
h is the height of the cylinder
We have to find the scale factor.
The length scale factor is = ![$\frac{6}{4}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B6%7D%7B4%7D%24)
![$=\frac{3}{2}$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B3%7D%7B2%7D%24)
Area scale factor ![$=\left(\frac{3}{2}\right)^2$](https://tex.z-dn.net/?f=%24%3D%5Cleft%28%5Cfrac%7B3%7D%7B2%7D%5Cright%29%5E2%24)
![$=\frac{9}{4}$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B9%7D%7B4%7D%24)
∴ Volume scale factor ![$=\left(\frac{3}{2}\right)^3$](https://tex.z-dn.net/?f=%24%3D%5Cleft%28%5Cfrac%7B3%7D%7B2%7D%5Cright%29%5E3%24)
![$=\frac{27}{8}$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B27%7D%7B8%7D%24)
Therefore, the volume of cylinder B is ![$=20 \times \frac{27}{8}$](https://tex.z-dn.net/?f=%24%3D20%20%5Ctimes%20%5Cfrac%7B27%7D%7B8%7D%24)
= 67.5 ![mm^3](https://tex.z-dn.net/?f=mm%5E3)
