240 minutes is how many minutes she went hiking
1 hour=60 minutes so
60×4=240
Answer:
Step-by-step explanation:
<u>Since T is midpoint, ST and TU have equal length:</u>
<u>Substitute the values and solve for x:</u>
- 6x - 8 = 4x + 9
- 6x - 4x = 9 + 8
- 2x = 17
- x = 17/2
- x = 8.5
Whooh
SA=4pir²
take derivitive
dSA/dt=8pir dr/dt
and do the volume as well
V=(4/3)pir³
dV/dt=4pir² dr/dt
we need to solve for dV/dt
to do taht we need dr/dt
so
dSA/dt=8pir dr/dt
given dSA/dt=3pi cm/sec
r=2
3pi=8pi2 dr/dt
3=16 dr/dt
3/16=dr/dt
now do the volume
dV/dt=4pir² dr/dt
r=2
dr/dt=3/16
dV/dt=4pi2² (3/16)
dV/dt=16pi(3/16)
dV/dt=3pi
nice
the volume of the sphere is decreasing at 3pi cm/sec as well
