You are planning your cousin’s birthday party. He wants to invite at least 250 adults and children combined. Each adult will be

olga_2 [115]

The system of inequalities is x+y≥250 and 3x+2y≤800.

Step-by-step explanation:

Given,

People to invite = at least 250

At least 250 means that the number can increase from 250.

Cups to be provided = only 800

It means the number cannot exceed 800.

Number of adults = A

Number of children = C

According to given statement;

x+y≥250

3x+2y≤800

The system of inequalities is x+y≥250 and 3x+2y≤800.

Here is a scary story for all!! Enjoy!!

The Ghost Man

Once upon a time there was a family, made up of two young ones and their parents. One day, the parents had to go out to do something important. They had to call someone to take care of their children, so they called a lady who was friends with them. Then the lady arrived and the parents left. She made sure the kids ate and then she put them on their bed to sleep. Their house had two floors and the kids were on the second floor upstairs. Then, she went to sit down on the couch and started to watch tv. She was watching tv when suddenly her phone rang, and she answered the phone. It was an unknown number. She answered it and a creepy voice said, “Have you gone to check on the kids?” When she heard that she automatically hung up. A few minutes later she heard it again, “Have you gone to check on the kids?”. She kept on hearing it for a few times until she started to be a little scared. She called the police as quickly as she could. She told the police that a man who was unknown kept calling her and threatening her. Then the police said that when that man calls again, he will try to locate the man that is calling her. Then the man called again and the police were able to locate the man. A few minutes later, the police called again and he said, “Get out of the house right now because the man that is calling you is on the second floor of your house”. Then the lady remembered that the kids were upstairs so she ran upstairs as fast as she could and it was too late, the kids were gone and there was blood all over their room. The kids were never seen again and lots of police men are still going to look out to find this mysterious man who is going out to get every person he sees. So be careful of what you do because you might hear their cries too.

Hope you like it!! ;)

Haley makes earrings and packages them into cube boxes that measure 1/6 foot wide. how many 1/6 foot cubic boxes can she fit int

navik [9.2K]

Answer: $28\ cubes$

Step-by-step explanation:

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

$V_{(c)}=s^3$

Where "s" is the lenght of any edge of the cube.

The formula for calculate the volume of a rectangular prism is:

$V_{rp}=lwh$

Where "l" is the lenght, "w" is the width and "h" is the height.

We need to find the volume of a cube box:

$V_1=s^3=(\frac{1}{6}ft)^3=\frac{1}{216}ft^3$

To find the volume of the shipping box, first we must convert the mixed number to an improper fraction:

$1\frac{1}{6}=\frac{(6*1)+1}{6}=\frac{7}{6}$

Then the volume of the shipping box is:

$V_2=lwh\\\\V_2=(\frac{7}{6}ft)(\frac{1}{3}ft)(\frac{1}{3}ft)=\frac{7}{54}ft^3$

Now, in order to find the number of cube boxes can Haley fits into a shipping box, you must divide the the volume of the shipping box by the volume of one cube. This is:

$\frac{\frac{7}{54}ft^3}{\frac{1}{216}ft^3}=28$

Find the slope-intercept form of the

3241004551 [841]

Parallel lines have the same slope.
So I plug in the -5 and -4
-4 = 1/2(-5) + b
-4 = -2.5 + b
b = -1.5

So I get y = 1/2x - 3/2
