Answer:
20
Step-by-step explanation:
If they were whole itd be ten but there halves so 20
Considering the ballon to be spherical
It's volume is given by 4/3(π r^3) by differentiating volume with respect to time we get rate of change of volume hence,
4πr^2(dr/dt)=600÷60=10
Substituting r=30cm
4π(30)*(30)(dr/dt)=10
dr/dt=rate of increase in bullion's radius=1/(360π)cm/s
Answer:
b=-108
Step-by-step explanation:
To solve this equation for b, you simply multiply each side by 18. The reason you do this is to isolate the b.
<u>
</u>
Distribute.
5(3x - 5)
5*3x - 5*5
15x - 25
