Alex Ar [27]

Answer:

answer c-[150-25(pi)]h cm

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

(Please have a look at the attached photo)

My answer:

Given the information:

  • box length-15
  • box width-10
  • box and jar height unknown (h)
  • radius of jar-5

As we all know that, the formula used to determine the volume of the box is:

V = the length* the width * the height

In this situation, we have:

V = 15*10*h

= 150h cubic units

  • The volume of the jar

V = the base*the height

In this situation, we have:

V = h*πr^{2}

<=> V = 5^{2} hπ = 25πh

=> The volume of the box that is not occupied by the jar

= The volume of the box - The volume of the jar

= 150h  - 25πh

= h(150 - 25π)

We choose C

What is the answer to this problem?
lions [1.4K]

The slope of a line is \frac{dy}{dx}

where d is the difference and y and x are the values.

In this case, the difference in y is 10 and the difference in x is 0

And division where the denominator being 0 leads to the answer being Undefined or Infinity as the line is directly on the y axis.
