31. At the candy store: => Ericka bought 3 kilograms of Cinnamon red hots and 1 kilograms of gummy bears for 21.00 dollars. => Irene bought 3 kilograms of cinnamon red hots and 3 kilograms of gummy bears for 39.00 dollars. Question: Find the costs of each kilograms. Notice that the cinnamon red hot that they both are the same, the only difference is the gummy bears, which added 2kilos for Irene. Now, let’s subtract => 39 – 21 = 18 dollars – this is the costs of 2 kilos of gummy bear => 18 / 2 = 9 dollars, thus the price of each kilos of gummy bear is 9 dollars, Now, let’s solve for the cinnamon => 21 – 9 = 12 dollars, to be divided with 3 kilos => 12 / 3 = 4 dollars – the price of cinnamon red hot per kilo.

Suppose that water is pouring into a swimming pool in the shape of a right circular cylinder at a constant rate of 3 cubic feet

gtnhenbr [62]

Answer:

Therefore the height of the water in the pool changes at the rate of $\frac{1}{3\pi}$ feet per minute.

Step-by-step explanation:

Given that the shape of swimming pool is right circular cylinder.

The rate of water pouring in the pool = 3 cubic feet per minute.

It means the rate of change of volume is 3 cubic feet per minute.

$\frac{dv}{dt}=3$ cubic feet per minute.

When the volume of the swimming pool changed it means the height of the water level of the pool change and the radius of the swimming pool remains constant.

Let the height of the pool be h.

The volume of the pool is = $\pi 3^2 h$ cubic feet
