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.
<span>0.1 more than 0.2
</span>⇒ 0.2 + 0.1

0.2 + 0.1 = 0.3
Answer: 0.3</span>
So for the triangle you would use the formula A= 1/2 bh (b represents the measurement of the base, h represents the height)
A= 1/2 30(40)
A= 1/2 1200
A=600
Now for the rectangle you use the formula A= l x w (l represents length, w means width)
A= 100 x 40
A= 4000
Now you just add the two answers together
A= 4000 + 600= 4600
