Answer:
4, 1
Step-by-step explanation:
If you take 2, 8 and make it a ratio you get 2 : 8.
Then you turn 2 : 8 into 1 : 4. That is your answer for a mile.
For the other answer, you want to divide 2 by 8.

Answer:
6 years
Step-by-step explanation:
we know that
The equation of a exponential growth is equal to

where
y ----> is the population
x ---> is the number of years since now
a ---> is the initial value or y-intercept
r ---> is the rate of change
we have


substitute


For y=19,600
substitute in the exponential equation and solve for x


apply log booth sides



Basically what you do is multiply the distance by the time, for example:
7 1/2 miles = 1/2 hour
so to get the amount of miles in one hour you get the miles and times it by two so it would go like this:
7 1/2 | 15 |
= | = |
1/2 | 1 |
then for one and a half you get the 1 hour answer and add the first one like this:
22.5 miles = 1 1/2 miles
and you continue that pattern!!! If you need more help just reply to this answer i'm in 7th grade so i can help with this stuff
