The plant increased a total of 4 inches.
Week 3, the plant was 8in and week 4, the plant was 12in.
To find our solution, subtract 8 from 12
12-8=4
We have the following given
mileage = 70 miles per gallon
distance = 60 km
Required: amount of fuel in gallons
First, we must convert the distance to miles, so
60 km (1 mi/1.6 km) = 37.5 mi
So, the amount of fuel is
37.5 mi / (70 mi/gal) = 0.54 gallons
Find the other angles then take the two angles of one triangle and take it away from 180. All the angles in an triangle add up to 180 degrees.

Answer:
Lori will have 
cavity if she brushed for 
each night.
Step-by-step explanation:
As the question suggests cavities developed varies inversely with the number of seconds spent on brushing.
Lets take the terms as 
,where 
is the constant of proportionality.
And
c = Number of cavities developed each year
t = Number of minutes spent on brushing per night
Now we will plugging the values of the given terms and find the value of ,for this we can re-arrange it as...
and 
Now as Lori will increase her brushing time so as the cavity will decrease.
So for this we have been given,
and 
.
As 
So as per Paul's observation if Lori brushed for 
at night she will have cavity on that year.
