Answer:
Step-by-step explanation:
Ivan and 3 others were evenly matched.
1+3=4
So there were 4 grandmas on the other team. :)
One way to solve this is to look at the size of the poster, and then subtract the size of the picture so you have the area that needs to be painted left.
Area of square poster - 3x × 3x = 9x^2
Area of painting - 2x × 2x = 4x^2
9x^2 - 4x^2 = 5x^2
The area is 5x^2
You solve it by dividing -40 over -5 then you will get x=8
Check the picture below
notice, if the "r" and "h" is the same for both, the cone's volume is just 1/3 of the cylinder's
-33/12. Lets forget the negative symbol.
12 goes into 33, 2 times with 9 remaining.
So now get the negative sign back.
It will be -2 9/12 but you can reduce that to -2 3/4.
Hope this helps :)
