Answer:
180 km
Step-by-step explanation:
The Nissan had traveled (120 km/h)(1/3 h) = 40 km when it had the puncture. It started from that location when the puncture was repaired at t = (1/3+1/2) = 5/6, where t is in hours. Then the two vehicles met (again) when ...
Matatu distance = Nissan distance
90t = 40+120(t -5/6)
0 = 40 +30t -100 . . . . . . subtract 90t, eliminate parentheses
60 = 30t . . . . . . . . . . . add 60
2 = t . . . . . . . . . . . . . 2 hours after leaving, the cars meet again
That distance from town A is ...
y = 90t = 90(2) = 180 . . . . km
Answer:
≈ 1.3 inches
Step-by-step explanation:
Given that:
- Sphere A = 30 cubic inches
- Sphere B = 10 cubic inches
As we know, the formula to find the volume of a sphere is;
V = π
So we have:
- Sphere A = 30 cubic inches
<=> π = 30
<=> = 90/4π
<=> r ≈ 4.13
- Sphere B = 10 cubic inches
<=> π = 10
<=> = 30/4π
<=> r ≈ 2.86
So the different between the radius of sphere A and B is:
= 4.13 - 2.86
= 1.27
≈ 1.3 inches
