Answer:
36/5 or 7 1/5 or 7.2
(These are all different forms of the same answer)
Method:
2 1/4 = 9/4
3 1/5 = 16/5
9/4 × 16/5 = 144/20
144/20 = 36/5
Answer:
Step-by-step explanation:
Since r=2 and |r|>1 the sum does not converge to any value. The sum does not exist for this infinite geometric series.
Answer:
80 square yards
Step-by-step explanation:
We know we have a width of 8 yards and a perimeter of 36.
how I figured it out was:
36=(8*2) * (x*2)
8*2=16
36-16=10
So now we know the length and width.
area of a rectangle is lw (length * width)
10*8=80.
Answer: 10
