Answer:
340 sheep.
Step-by-step explanation:
There is a decrease of 640 - 576 = 64 sheep in the first year.
This is 1/10 of the previous year, so the number in year 2 is 0.90 of the number of sheep in year 1, so a model for this could be:
640(0.90)^x where x is the year.
So after 6 years the estimate would be 640 *(0.90)^6
= 340 sheep.
Note the improper fraction. Change it into a mixed fraction
3/2 = 2/2 + 1/2
2/2 = 1
5 + 1 1/2
Simplify.
5 + 1 = 6
6 1/2 is your answer
hope this helps
I think it would be meters

Answer:
18 miles
Step-by-step explanation:
<u>Let </u>
- The number of miles = x .
<u>According</u><u> to</u><u> Question</u><u> </u><u>,</u>
- 100 + 0.5(x) = 40 + 0.8(x)
- 100 + 0.5x = 40+ 0.8x
- 100 - 40 = 0.8x - 0.5x
- 60 = 0.3x
- x = 60/3 * 10
- x = 18
