Step-by-step explanation:
I answered that already.
Answer:
3 , 4 , 4 (two x's on this spot), 5
Step-by-step explanation:
you need an x in each point (A, B, C, D, E) given in the chart
notice point B and E are the same
3 , 4 , 4 (two x's on this spot), 5
I believe the bottom left shows the right answer
Answer: it's not necessary so i can't round to the nearest tenth
The difference between the average speed in km/h of their trains are 53.538 km/h.
Step-by-step explanation:
The given is,
Davit's train travels 90 km in 50 minutes.
Mila's train travels 210 km. It leaves at 12:05 and arrives 13:35.
Step:1
From the given,
Time required to milas train travels 210 km
= 12:05 - 13:35
= 1.30 hours
Step:2
Time to Davit's train travels 90 km is need to convert in hours from minutes,
= 50 minutes
= hours
= 0.833 hours
Step:3
Average rate of Davits train,
=
=
= 108 km/h
Step:4
Average rate of Mila's train,
=
=
= 161.538 km/h
Step:5
The difference between the average speed of the both trains in km/h,
= 161.538 - 108
= 53.538 km/h
Result:
The difference between, the average speed of their trains are 53.538 km/h.
Answer:
6 seconds
Step-by-step explanation:
We have to find the t-intercepts of the function. To do so, let's set h(t) = 0.
0 = 96t - 16t²
0 = 16t(6 - t) -- Factor 96t - 16t²
16t = 0 or 6 - t = 0 -- Use Zero Product Property
t = 0 or t = 6 -- Solve for t
We're not looking for the solution t = 0 because that represents when the debris was launched. Therefore, the answer is 6 seconds.
