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:
37 cents
Step-by-step explanation:
Given that a grocery store sells Swiss cheese
Rate per pound = 5.90 dollars
1 pound =16 oz,
Hence cost of 16 ounces is given as 5.90
SO cost of one ounce of Swiss cheese =
Or 36.875 cents
Round off to nearest cent as
37 cents since after decimal digit 8 is more than 5.
Hence answer is 37 cents
