Step-by-step explanation:
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.
Answer:
x = ±3
Step-by-step explanation:
2 = |x| - 1
Add 1 to both sides: |x| = 3
⇒ x = ±3
I'm going to use m for minutes
Cell carrier 1
0.15 per minute (0.15m)
$26.50 first, and then add on for every minute
cost carrier 1 = 0.15m + 26.50
carrier 2
0.25 per minute (0.25m)
$14.50 first, and then add on for every minute.
cost carrier 2 = 0.25m + 14.50
to find out when they cost the same, make the two costs equal to each other:
0.15m + 26.50 = 0.25m + 14.50
all that's left is to solve for m
0.15m + 26.50 = 0.25m + 14.50
subtract both sides by 0.15 m
26.50 = 0.2m + 14.50
subtract both sides by 14.50
12 = 0.1 m
divide both sides by 0.1
m = 120
the phone carriers will have the same cost at 120 minutes
