Darcy harvests 8 3/4 acres of corn every 5/6 of an hour. Darcy harvests corn at a constant rate. How many acres does she harvest
Inessa05 [86]

Answer: 10 1/2, which can be simplified as 10.5

Explanation: First, set up a proportion with acres of corn to time in hours:

8 3/4 acres = x acres

5/6 hour = 1 hour

Reorder the terms:

x = (8 3/4) / (5/6)

To figure that out the math, change the mixed fraction to an improper fraction, and change the division into a multiplication:

x = (35/4) * (6/5)

Next cancel out:

x = (7/2) * (3/1)

x = 21/2

Lower that faction the the lowest denominator:

21/2 = 10½

Thus, your answer is 10½, or in other words 10.5

Hope this helps! :)

DochEvi [55]

Answer:

512

Step-by-step explanation:

1st term =a

common ratio = r

a*r with the exponent n-1

a=4    r=2 n=8

8th term    4*(2 at the seventh power)= 512

OR

1st term  :4

2nd term = 4*2=8

3rd term 8*2=16

4th term  12*2=32...............8th term 256*2=512
