Hello,
Please, see the attaced file.
Thanks.
Cone : 1
cube:6
Square pyramid:5
Triangular pyramid:4
So you have the equation y = 3x + 22.
x = months starting after 2014
y = total number of comic books
So think about it, when x = 0, y= 22, which means that he started with 22 comic books
When x=1 (meaning after 1 month), y = 25, so after 1 month the amount of comic books increased by 25-22 = 3.
So you can see the answer is C.
The cross-section of a sphere is a circle . The area of a circle can be calculated by the formula A= 
Where r is the radius of the circle.
Given :
Solving for r we have:
Or r= 10.
The area of a sphere is calculated by the formula :
Substituting r value we have:
SA= 
The total surface area of this sphere is 400π .
Positive numbers are always greater than -15. Therefore, it's a greater than.
-2x = - 15
Dividing both sides by -2, we get
x = 7.5
Negative cancels on both sides, so we get a positive equation.
Positive numbers are always greater than -15. Therefore, it's a greater than.
What is greater than or less than?
- Greater than and less than are the comparison symbols.
- When the number is bigger or smaller than the other, then greater than and less than symbols are used.
- If the number is greater than the other, the greater than (>) symbol is used.
- If the number is lesser than the other, the less than the (<) symbol is used.
