Answer:
12.5 leters
Step-by-step explanation:
If you take the 4 liters she used to cover 50 doors,
This is fairly simple. Divide 2,871,000 by 10 and that's your answer!

Also, since you're dividing by a factor of 10 (or in this case, <em>10</em>) you can just take away as many places as are zeros in the number you're dividing from. This works for <em>10, 100, 1,000, 10,000, etc. </em>In this case, since there is only one zero in 10 you only take away one place marking, which gives you 287,100.
Slope intercept form is y=MX+b.
M is the slope, x is the x intercept, and b is the y intercept
the slope is

An intercept is where the formula crosses the axis. therefore, the x intercept is .5, and the y intercept is 1
so the point slope formula is
Answer:
974
Step-by-step explanation:
Initial × Increase percentage ^ Time
500 × (1 + 10%)^(70/10)
500 × 1.1^7
= 974.36
The population of the town in 70 years will be 974.
