You could buy $7 for each tin of popcorn and get 8, $8 for 7 tins of popcorn, or $4 for 14 tins of popcorn
Step-by-step explanation:
M is the midpoint of AB. First, find the coordinates of M.
M = ((4 + 0) / 2, (2 + 4) / 2)
M = (2, 3)
Now find the slope of MC:
m = (15 − 3) / (8 − 2)
m = 12 / 6
m = 2
Find the slope of AB:
m = (4 − 2) / (0 − 4)
m = 2 / -4
m = -1/2
The slopes are opposite inverses, so the two are indeed perpendicular.
Answer: 
Step-by-step explanation:
The rate of change is a measure in which one variable is modified in relation to another. In this case we have the variables:
Temperature in 
Time in 
Now, to calculate the rate of change, we have to divide one variable by the other. In this case the change in temperature
divided by the time variation
.
Hence, assuming the ambient temperature of the glass is
and the elapsed time
we have:

Answer:
3 weeks
Step-by-step explanation:
25+1.75=26.75
Saira can only withdraw up to $80.25
26.75 x 3 = 80.25
$ 1 U.S. dollar = 0.76 euros
so $ 30 U.S. dollars = (30 * 0.76) = 22.8 euros <==
