Jessie works at least 36 hours a week. She works as a math
Olegator [25]

Answer:

The feasible region is unbounded which is the shaded portion in the graph.

Step-by-step explanation:

Given that, the number of hours Jessie works as a teacher and tutor is y and x respectively, which can't be negative.

So, x\ge0\;\cdots(i)

y\ge0\;\cdots(ii)

She works at least 36 hours a week.

\Rightarrow x+y\ge 36

\Rightarrow y\ge 36-x\;\cdots (iii)

She works as a teacher for al least twice the number of hours she works as a tutor.

\Rightarrow y\ge2x\;\cdots(iv)

The boundary of the inequalities from equations (i), (ii), (iii), and (iv) are

x=0, y=0, y=36-x and y=2x.

The feasible region is the shaded portion which is the unbounded region as shown in the graph. Any point P(x,y) from the feasible region will satisfies all the constraints.

A cylinder has 18 inch diameter and is 15 inches tall it is filled to the top with water a 6 inch diameter ball is in place with
k0ka [10]

Answer: 1,179\pi\ in^3

Step-by-step explanation:

The volume of a cylinder can be calculated with the following formula:

V=\pi r^2h

Where "r" is the radius and "h" is the height.

The volume of a sphere can be found with this formula:

V=\frac{4}{3}\pi  r^3

Where "r" is the radius.

Then, volume of the empty cylinder is:

V_c=\pi (\frac{18\ in}{2})^2(15\ in)\\\\V_c=1,215\pi \ in^3

And the volume of the ball is:

V_b=\frac{4}{3}\pi  (\frac{6\ in}{2})^3\\\\V_b=36\pi \ in^3

 Finally, you need to subtract them in order to calculate how much water is in the cylinder:

1,215\pi \ in^3-36\pi \ in^3=1,179\pi\ in^3
