Answer:
dy/dt = - (1/5) ft/s = - 0.2 ft/s
Step-by-step explanation:
Given
L = 5 ft
Qin = 25 ft³/s
Qout = 30 ft³/s
h = 10 ft
dy/dt = ?
We can apply the relation
ΔQ = Qint - Qout = 25 ft³/s - 30 ft³/s
⇒ ΔQ = - 5 ft³/s
Then we use the formula
Q = v*A
where Q = ΔQ, A = L² is the area of square base and v = dy/dt is the rate of change in the depth of the solution in the tank
⇒ ΔQ = (dy/dt)*L²
⇒ dy/dt = ΔQ/L²
⇒ dy/dt = (- 5 ft³/s)/(5 ft)²
⇒ dy/dt = - (1/5) ft/s = - 0.2 ft/s
Answer:
6
Step-by-step explanation:
x=6
ax+bx=cx
10+bx=16
10+6=16
x=6
Answer:
I think so, but maybe if the schools are different they change.
Answer:
Debbie's Deals has the better deal with a price of $0.19 per ounce compared to Bill's Bargains at $0.21 per ounce.
Step-by-step explanation:
Divide $3.36 by 16 = $0.21
Divide $7.60 by 40 = $0.19
Debbie's Deals sells the Circle O's cereal for a cheaper per ounce price thus it's the better price and the better deal.
Good luck!
