Answer:
Is it going to be $19.55?
Step-by-step explanation:
Answer:
t = 24
Step-by-step explanation:
Given that t varies inversely with a then the equation relating them is
t = 
← k is the constant of variation
To find k use the condition t = 2 when a = 36, that is
2 = 
( multiply both sides by 36 )
72 = k
t = 
← equation of variation
Given a = 3, then
t = 
= 24
Answer:
37
Step-by-step explanation:
45+98+x=180
Answer:
24 grams
Step-by-step explanation:
Since there are three of them, I multiply by the mass, which is 8, and get 24 grams. Hope this helps!
Let h=height of water
Let r=radius of water surface
r/h=16/8 =2, so r=2h.
The volume of water is:
v=(1/3)×π×r²×h
=(1/3)×π×(2h)²×h
=4/3πh³
dv/dh=4πh^2
By chain rule:
dv/dt=dv/dh×dh/dt
but
dv/dt=4
thus:
4=(4πh)×dh/dt
dh/dt=4/(4πh²)
when h=6cm we have:
dh/dt=4/(4π6²)
=0.00884 cm³/min
