Answer:
The sum of the first 5 terms is -244
Step-by-step explanation:
To calculate the sum of the geometric series, we need the first term, the common ratio and the number of terms we would like to sum.
The first term here is -4
The common ratio is T2/T1 or T3/T2 = 12/-4 = -3
number of terms n = 5
The formula to use is;
Sn = a(1-r^n)/(1-r)
Plugging these values, we have;
Sn = -4(1-(-3)^5)/(1-(-3))
Sn = -4(1+243)/4 = -1(244) = -244
10,000,000 + 5,000,000 + 300,000 + 40,000 + 70 + 8
Answer:
Powerpoint
Step-by-step explanation:
I think that a powerpoint presentation would be best. With the first slide, put the picture and a title. With each slide, put more than one word and maybe an example. Make it colorful and maybe put some math puns in some of them.
Hope this helps.

They only have 3 and two in common when you fully factor them. 3×2= 6
6 is the greatest common factor.
Answer:
Step-by-step explanation:
We have been given that a cylindrical backyard pool 3 feet high and 20 feet in diameter. We are asked to find the volume of water in pool.
We will use volume of cylinder formula to solve our given problem as:
, where,
r = Radius of cylinder,
h = Height
We know that radius is half the diameter, so radius of cylinder would be 
feet.
Therefore, the pool holds 942 cubic feet of water.
