Answer:
Collen's average speed was 11.875 miles/h
Step-by-step explanation:
The average speed is given by the total distance travelled divided by the time at which the route was completed. So in this case the total distance is 9.5 miles and the time to complete it was 0.8 hour. We then have:
average speed = total distance/ time
average speed = 9.5/0.8 = 11.875 miles/h
Collen's average speed was 11.875 miles/h
Answer:
(5.33 + 2h) ≥ 7
h ≥ 0.835
Step-by-step explanation:
Let in the last two days Julian has to practice the drum for h hours each.
Then in two days, he has to practice 2h hours,
He has already practiced 
hours before those last two days.
Therefore, he has practiced this week by (5.33 + 2h) hours.
Now, given that Julian needs to spend at least 7 hours each week practicing the drums.
Hence, we can write the inequality
(5.33 + 2h) ≥ 7
⇒ 2h ≥ 1.67
⇒ h ≥ 0.835 hours
Therefore, Julian has to practice for 0.835 hours for the last two days of the week. (Answer)
Answer:
10
Step-by-step explanation:
h(x) = 6 - x
(h o h)(x) = h(h(x)) = 6 - h(x) = 6 - (6 - x) = 6 - 6 + x = x
(h o h)(x) = x
(h o h)(10) = 10
Answer:
Option C) c+9 is correct
The sum of the number of cars and 9=c+9 is correct algebraic expression representation for given phrase
Step-by-step explanation:
Given that c=the number of cars in a parking lot.
The phrase given is "the sum of the number of cars and 9"
To find the algebraic expression which represents the given phrase :
The algebraic expression to the given phrase is c+9
That is option C) c+9 is correct
The sum of the number of cars and 9=c+9 is correct algebraic expression representation for given phrase
Answer:
The slope would be 2
