a conical tank with vertex down is 10 feet across the top and 12 feet deep. If water is flowing out of the tank at a rate of 12
TiliK225 [7]

Answer:

The water level is dropping at a rate of 0.24 ft/s

Step-by-step explanation:

Here, we simply want to calculate the change in depth (height of the cone) , given the volume change

Mathematically, we have the volume of a cone as;

V = 1/3 * π * r^2 * h

we are given dv/dt as 12 ft^3/m

dv/dh = 1/3 * π * r^2

Substituting the value for the radius, we have

dv/dh = 1/3 * 22/7 * 4^2 = 50.29

dh/dt = dh/dv * dv/dt

dh/dv = 1/(dv/dh) = 1/50.29

Thus,

dh/dt = 1/50.29 * 12

dh/dt = 0.24 ft/s

What does 351 = (y × 8) + 7 equal
bogdanovich [222]

Simplify brackets

351 = y * 8 + 7

Regroup terms

351 = 8y + 7

Subtract 7 from both sides

351 - 7 = 8y

Simplify 351 - 7 to 344

344 = 8y

Divide both sides by 8

344/8 = y

Simplify 344/8 to 43

43 = y

Switch sides

<u>y = 43</u>
