As a butcher, you sell beef in 3.5-pound packages. You anticipate needing 25 packages for the next two days. The
bekas [8.4K]

Answer:

O weight in kilograms = 25 x 3.5 ÷ 2.2

Step-by-step explanation:

As a butcher, you sell beef in 3.5-pound packages. You anticipate needing 25 packages for the next two days.

Therefore, the total number of pounds for the 25 packages =

3.5 pound packages × 25

= 87.5 pounds

We are told that : The wholesaler from whom you purchase large pieces of meat measures the weight of the beef in kilograms.

Note that:

2.2 pounds = 1 kg

Hence:

87.5 pounds =

= 87.5÷ 2.2

= 39.772727273 kg

He needs to buy 39.772727273kg from the wholesaler

The equation can you use to determine the weight of the beef, in kilograms, that you need to purchase from the wholesaler is:

O weight in kilograms = (25 x 3.5) ÷ 2.2

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

                                          =9\pi h cubic feet

Therefore,

v =9\pi h

Differentiating with respect to t

\frac{dv}{dt}= 9\pi \frac{dh}{dt}

Putting \frac{dv}{dt}=3

3=9\pi \frac{dh}{dt}

\Rightarrow \frac{dh}{dt} =\frac{3}{9\pi}

\Rightarrow \frac{dh}{dt} =\frac{1}{3\pi}

The change of height of the pool does not depend on the depth of the pool.

Therefore the rate of change of height of the water in the pool is \frac{1}{3\pi} feet per minute.
