Answer:
16 hours and 20 minutes.
Step-by-step explanation:
Please consider the complete question.
Rita's family is moving to Grand Junction to Dallas, which is 980 miles. The moving van averages 60 miles each hour. About how many hours does the van take to reach Dallas?
To find the time taken by van to reach Dallas, we will divide total distance by speed.
Let us convert 0.3333 hours into minutes by multiplying 0.3333 by 60.
Therefore, it will take 16 hours and 20 minutes for the van to reach Dallas.
Answer:
80
Step-by-step explanation:
You plug in 1200 for x.
C(1200)=0.05(1200) +20
Then solve. Multiply first then add.
60+20
80

Answer:
OPTION D
Step-by-step explanation:
We have to determine which option determines the function given above.
To determine the function, just substitute the values and compare LHS and RHS.
we have 
Here, 
is the domain and 
is the co-doamin.
Therefore, 
Now, OPTION A: 
Substitute x = 4. We get f(x) = 3 
18.
So, OPTION A is rejected.
Similarly, OPTION B: 
Substitute x = 4. We get f(4) = 22 18.
It is rejected as well.
Now, for OPTION C: 
Substitute x = 4. We get f(4) = -3 18.
So, OPTION C is also rejected.
OPTION D: 
Substitute x = 4. We get f(4) = 18.
Substitute the remaining points in domain as well. We notice that it exactly matches the given function. So, OPTION D is the answer.
