Answer:
Total people = 240
Step-by-step explanation:
Let the total number of people by 'x'.


Number of children = 100
When we subtract the total number of men and women from the total people 'x', we get the number of children.



x = 20 * 12
x = 240
<h3> Total number of people = 240</h3>
Answer:
x = 21/4
Step-by-step explanation:
re-arrange the equation
-4+5x-7-3x = 10-2x (move 3x to the other side)
-4+5x-7-3x+2x = 10 (move 2x to the other side)
5x-7-3x+2x = 10+4 (move 4 to the other side)
5x-3x+2x = 10+4+7 (move 7 to the other side)
4x = 21 (add up both sides)
x = 21/4 (divide both sides by 4
Answer:
The least common multiple of 30, 25, 4 is 150.
Step-by-step explanation:
The given numbers are 30, 25 and 4.
The factors of given numbers are



The L.C.M of given numbers is a smallest number that divides the given numbers completely.


Therefore the least common multiple of 30, 25, 4 is 150.

The area of the shaded sector of a circle is 64 pie cm^2
Here we are given that there is a circle: whose radius is
cm and the angle formed by two radius that is angle of the sector is
.
The area of the sector of circle is basically the area of the arc of a circle.
The two combination of two radii forms the sector of a circle while the arc is in between these two radii.
Area of sector is given by:
.л
Substituting the given value in the formula of area of sector:
Area of sector is=
We get after solving,
Area of sector=
pie cm^2
So from the given options, option 4 is correct.
Hence the area of the sector is 64 pie cm^2
