Answer:
-6 7/hr= -6F per hour
Step-by-step explanation:
a rate of change can be defined as:
R=(total change in some quantity) (time in which the change happened)
In this case we know that the temperature dropped -30F in a given time, then we already know that:
Total change in some quanity =-30F now we know that this change took place between the 1:00pm and the 7:00 pm the total amount of ime between these two hours is:
T= (7.00 - 1.00 hr)= 6.00 hr
this means that the change happened =6 hours.
then we can replace these values in the above equation to get:
R=(-30F)/(6hr)=-6F/hr
this means that for each hours that passes the temperature decreases 6F
we also can write that this rate as:
R=-6F/HR =-6F per hour.
the answer is three look where it says 4-1 is 3
Answer:
D
Step-by-step explanation:
Answer:
Kirsten travels 7.5 miles to go to work.
Step-by-step explanation:
Bike: 10 MPH
Time: 1/4 Hour
1/4 of 10 = 2.5
Distance travelled on bike: 2.5 miles
Train: 20 MPH
Time: 1/4 Hour
1/4 of 20 = 5
Distance travelled by train: 5 miles
Add the distances together.
5 + 2.5 = 7.5
7.5 miles
that equation has to be wrong because it gives me a decimal
