3 (three) times x (a number) - (minus) 7 (seven)
Three times a number minus seven
You could also say seven less than the product of a number and three.
<u>We are given</u>
- Radius of Earth; 6.4 x 100 meters = 640 meters
Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.

When we substitute the radius in the formula, we get;


Take π as 3.14


Simplify the numerator;


Divide the numerator by 3;


Answer:
a) 2450
b) 1890
c) 1050
Step-by-step explanation:
Given:
- Available Group = 9 M & 7 F
- Committee of= 4 M and 4 W to be formed
Find:
- (a) 2 of the men refuse to serve together?
- (a) 2 of the women refuse to serve together?
- (a) 1 man and 1 woman refuse to serve together?
Solution:
- The question pertains to a selection process, We will use combinations for each case as follows.
part a)
- Since 2 men cant be selected together. Then we have to discount for one man while selecting Man for the committee. Hence, the combinations are:
8C4 x 7C4 = 2450
part b)
- Since 2 women cant be selected together. Then we have to discount for one woman while selecting them for the committee. Hence, the combinations are:
9C4 x 6C4 = 1890
part b)
- Since 1 women and a man cant be selected together. Then we have to discount for one woman and one man while selecting them for the committee. Hence, the combinations are:
8C4 x 6C4 = 1050

Answer:
6.4 units (nearest tenth)
Step-by-step explanation:
Distance between 2 points

Distance between A and B
![= \sqrt{[ - 1 - ( - 5)]^{2} + ( - 1 - 4)^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%5B%20-%201%20-%20%28%20-%205%29%5D%5E%7B2%7D%20%2B%20%28%20-%201%20-%204%29%5E%7B2%7D%20%20%7D%20)



= 6.4 units (nearest tenth)
