Answer:
2 1/3 hours or 2 hours 20 minutes.
51.4 mph to 1 decimal place.
Step-by-step explanation:
Time = distance speed
First 50 miles time taken = 50 / 60 = 5/6 hours
Second 50 miles - time = 50/40 = 5/4 hours.
Final 20 miles - time taken = 20 / 80 = 1/4 hours.
Total time taken = 5/6 + 5/4 + 1/4
= 5/6 + 6/4
= 10/12 + 18/12
= 28/12
= 7/3 or 2 1/3 hours or 2 hours 20 minutes.
Average speed = total distance / total time
= 120 / 7/3
= 120 * 3/7
= 51.4 mph to 1 decimal place.
On the graph the X axis (the horizontal line) should have a dot 9 spaces over and 8 spaces down. Now it wants you to reflect it. Simply draw the same figure in mirror form
Answer:
It's d. 0.
Step-by-step explanation:
The log (to any base) of 1 = 0, so log8 1 = 0, and the whole expression is equal to 0:
0 * log3 27 = 0.
Answer:
6√3, 10.39230484
...
Step-by-step explanation:
In the theorem, a^2+b^2=c^2, and c equals the longest side (in this case, hypotenuse). The known leg can be a. So now, we can substitute and our equation is 36+b^2=144. Subtract 36 from both sides, & b^2=108. Depending on what form the problem wants you to answer with, the answer could be 6√3, 10.39230484
..., or the decimal simplified.
