Answer:
5/6 cup
Step-by-step explanation:
6 cups of water: 5 cups of baking soda are needed.
divide by 6
1 cup of water: 5/6 cups of baking soda are needed.
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
Step-by-step explanation:
A straight line adds up to 180°
m+3m=180°
4m=180°
m=45°
3m=45°
angle CBD=3(45)
=135°
Answer:
u = 5
Step-by-step explanation:
9(u+2) = 63
9(5+2) = 63
9(7)=63
Answer:
y=1/9x-7/9
Step-by-step explanation:
x=9y+7
solve for y
9y=x-7
y=1/9x-7/9
