What is the density of a bowling ball with a mass of 3.0 kg and a volume of 0.0050 m3?
In-s [12.5K]
6.0⋅<span>102</span><span>kg m<span>−3</span></span> Explanation:

In order to find the density of the bowling ball, <span>ρ </span>, you must determine the mass one unit of volume of this bowling ball would have.

Notice that the problem provides you with the volume of the bowling ball expressed cubic meters, <span><span>m3</span> </span>, which means that one unit of volume would be <span><span>1 m3</span> </span>.

Now, you know that a volume of <span><span>0.0050 m3</span> </span> has a mass of <span>3.0 kg </span>. You can use this known proportion as a conversion factor to figure the mass of <span><span>1 m3</span> </span>

<span><span>1<span>m3</span>⋅<span>3.0 kg<span>0.0050<span>m3</span></span></span>=600 kg</span> </span>

So, you know that one unit of volume has a mass of <span>600 kg </span>, which means that the bowling ball's density is equal to

<span><span><span>ρ=6.0⋅<span>102</span><span>kg m<span>−3</span></span></span><span>−−−−−−−−−−−−−−−−−</span></span> </span>

The answer is rounded to two sig figs.

Demand for an electric fan is related to its selling price p (in dollars) by the equation n = 1960 − 70 p where n is the number
alexandr402 [8]

Answer:

  $14

Step-by-step explanation:

The revenue from sales of fans is the product of the number of fans sold and the price at which they are sold:

  R(p) = n·p = (1960-70p)p

  R(p) = 70(28 -p)p

This equation describes a parabola that opens downward and has zeros at p=0 and p=28. The axis of symmetry is halfway between those zeros, at p=14. It goes through the vertex or point of maximum revenue.

The price for maximum revenue is p = 14 dollars.
