What is an example of when you might need to use decimals and other rational numbers in everyday life?

1 answer:

5 0

Well, in the store, when you buy something, there are decimals, also, speed limit for your car, and time, but that is not an exact thing for this question, because 60 can't be a decimal. you cant make it so you can show 60 seconds as a decimal without an irrational number. sometimes, the number just goes on forever.

The radius r of a sphere is increasing at a constant rate of 0.04 centimeters per second. (Note: The volume of a sphere with rad

-Dominant- [34]

Answer:

The rate of the volume increase will be $\frac{dV}{dt}=50.27 cm^{3}/s$

Step-by-step explanation:

Let's take the derivative with respect to time on each side of the volume equation.

$\frac{dV}{dt}=4\pi R^{2}\frac{dR}{dt}$

Now, we just need to put all the values on the rate equation.

We know that:

dR/dt is 0.04 cm/s

And we need to know what is dV/dt when R = 10 cm.

Therefore using the equation of the volume rate:

$\frac{dV}{dt}=4\pi 10^{2}0.04$

$\frac{dV}{dt}=50.27 cm^{3}/s$

I hope it helps you!

A small company is creating a new product to sell to buyers. They have estimated that it will cost them $6 to produce each item

miv72 [106K]

Answer:

$347,600

Step-by-step explanation:

There is fixed startup cost of 242,000 no matter how many units they product.

Also, each unit costs 6 to produce, so to produce 17,600 items, it's going to cost:

17,600 * 6 = 105,600

Along with this the fixed startup cost of 242,000, would make total cost:

Total cost = 242,000 + 105,600 = $347,600
