Since it is looking for the sum
at S3, replace n with 3 , 2, and 1 , solve the equation and add all of answers together
when s = 3 the equation becomes 5(1/3)^3-1
5(1/3)^2 = 5/9
when s = 2 the equation becomes 5(1/3)^2-1
5(1/3)^1 = 5/3
when s = 1 the equation becomes 5(1/3)^1-1
5(1/3)^0 = 5
5/9 + 5/3 + 5 = 65/9
the answer is the 3rd choice
A+b=45
a>b
a=b+7
→
b+7+b=45
2b+7=45
2b=38
b=19
a=19+7=26
Answer:
if the length, width and height of a cube quadruple, then the volume of the cube will be multiplied by 64.
Step-by-step explanation:
Given a cube of width W, height H and length L, the volume of the cube will be: Volume = W*H*L
If all the three parameters quadruple, then:
New Width = 4W
New Height = 4H
New Length = 4L
New Volume = 4W*4H*4L = 64WHL
Therefore, if the length, width and height of a cube quadruple, then the volume of the cube will be multiplied by 64.
Answer:
12.87
Step-by-step explanation:
Find the difference between 50 and 37.13
50 - 37.13 = 12.87
Hope this helped
Answer:
Straight
Step-by-step explanation:
If the angle is flat or 180 degrees, it is straight
If the angle is like an L or 90 degrees, it is right
If the angle is less than 90 degrees, it is acute
If the angle is more than 90 degrees, it is obtuse
Hope this helps!!
