igomit [66]

Answer:

$5.10

Step-by-step explanation:

The owner buys 5 panes of glass for $12.75. So to find the cost of 1, we need to divide the total cost by the amount of planes. In this case, 12.75 divided by 5. This gives you $2.55 per plane. And since he is buying 2 more, we would multiply the cost of the plane (2.55) by the amount we are buying (2). So we do 2.55 X 2 and we get $5.10

Why might two people in the same state with the same salary pay different rates of income tax?
vekshin1

One <em><u>possible answer</u></em> is:

They could have had extra money withheld when they completed their W-4.

Explanation:

When you complete the W-4, there is a worksheet that you fill out to help you decide what number of exemptions to claim. However, you can choose to have more money withheld, to ensure you have no tax obligations at the end of the year. This would cause the amount of money withheld from two different people to potentially be different.

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
