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

Solve the system using elimination.5x-9y=12x-9y=-12
NemiM [27]

Answer:

x = 6

y = 2

Explanation:

To solve the system using elimination, we need to multiply the second equation by -1, so the second equation is equivalent to:

x - 9y = -12

-1 (x - 9y) = -1 (-12)

-x + 9y = 12

Then, we can sum this equation and the first equation. So:

5x - 9y = 12

-x + 9y = 12

4x + 0 = 24

So, we can solve for x, as:

4x = 24

4x/4 = 24/4

x = 6

Then, we can replace x by 6 on the first equation and solve for y, so:

5x - 9y = 12

5(6) - 9y = 12

30 - 9y = 12

30 - 9y - 30 = 12 - 30

-9y = -18

-9y/(-9) = -18/(-9)

y = 2

Therefore, the solution of the system is x = 6 and y = 2
