This one is about rate of change and has 2 questions that need two answers. At 6:00 am, there was 1 inch of snow on the ground. By 11 am, there were 4 inches of snow on the ground. What is the average rate of change?

If the snow continues to fall at the same rate, how much snow will be on the ground by 1:00 pm.

0.6 inches per hours

5.2 inches on the ground by 1:00 pm

Step-by-step explanation:

Let x = number of hours after midnight

Let y = height of snow (in inches)

Information presented as ordered pairs (x, y):

(6, 1)

(11, 4)

Written as a linear equation:

1:00 pm = 13 hours after midnight

Therefore, when x = 13:

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

The solution is given in the image below

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
