Answer:
A. t > 2.5
Step-by-step explanation:
If she wants to achieve <em>more </em>than 590, we already know the sign would be greater than (>).
All we have to do is divide 590/236, which gives us 2.5.
Therefore, she will have to ride more than 2.5 hours to reach her goal, t > 2.5
Hope this helps :)
Good luck on your test.
Answer:
The wheel will make 40 revolutions.
Step-by-step explanation:
We are given;
Diameter = 77 cm = 0.77m
Radius = 0.77/2
Radius = 0.385 m
Speed = 1.1 m/s
time = 1min 28 sec = 88 sec
Now, we know that;
Distance = speed×time
Thus;
Distance = 1.1 × 88
Distance = 96.8 m
Also,
Number of revolution = distance/circumference
Number of revolutions = 96.8/(2 × π × 0.385)
Number of revolutions ≈ 40
Answer:
Option B is correct
Step-by-step explanation:
The multiply of matrix A by matrix B that is inverse of A, must result in an identity matrix that has form shown in option B

Answer:
13 pages : 1/2 hour Multiply both sides by 2
26 pages : 1 hour ------>> 26 pages/hr
Flip over 26 pages/hr ----->>> hr / 26 pages = 1 hr / 26 pages
Split up the fraction: (1/26) hr / page
