The average rate of growth of the ice can be found by dividing the thickness by the number of days of growth
The growth rate of the ice over the 8 days is <u>0.375 inches/day</u>
Reason:
The known information on the ice are;
The time it took the ice to reach a thickness of 3 inches = 8 days
Required:
The (average) rate that the ice is growing in c=inches per day
Solution:

Therefore;

The (average) rate of growth of the ice over the 8 days is <u>0.375 inches per day</u>

Answer:
x=13
Step-by-step explanation:
one angle of triangle=85
parallel lines and vertical angles
the second angle is 82:
sum of angles of the triangle=180
x+85+82=180
x+167=180
x=180-167
x=13
2/9
Step-by-step explanation:
Slope in calculated as the ratio of change in y values divided by the change in x values
slope, m=Δy/Δx
Δy=8-6=2
Δx=6--3=9
m=2/9
