B=2 and 4
C=1,2,7 and 14
D=1,2,4,and 8
Answer:
8
Step-by-step explanation:
3(2)-2(1-2) / 3-2
6+2 / 1
8/1
= 8
Answer:
He can use the factors of 36 to determine the number of groups he can divide the class into such that they are equal.
The Factors (excluding 1) are;
2, 3, 4, 6, 9, 12, 18
Using these therefore he can divide them;
- Into 3 groups each with 12 people.
- Into 4 groups each with 9 people.
- Into 6 groups each with 6 people.
- Into 9 groups each with 4 people.
- Into 12 groups each with 3 people.

Answer:
6 inches
Step-by-step explanation:
3392.92 cubic inches of liquid distributed in 30 spheres would give each sphere's volume to be:
Now we equate 113.1 to the formula for volume of a sphere and solve for r:
![\frac{4}{3}\pi r^3=113.1\\r^3=\frac{113.1}{\frac{4\pi}{3}}\\r^3=27\\r=\sqrt[3]{27} =3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3%3D113.1%5C%5Cr%5E3%3D%5Cfrac%7B113.1%7D%7B%5Cfrac%7B4%5Cpi%7D%7B3%7D%7D%5C%5Cr%5E3%3D27%5C%5Cr%3D%5Csqrt%5B3%5D%7B27%7D%20%3D3)
The radius of each of those spheres is 3
We know diameter is twice the radius , so diameter would be 3 * 2 = 6 inches
