Write an
inequality that can be used to determine the number of t-shirts (T) Shana must
sell each month in order to make a profit for the month.


Answers

Answer 1
Answer: 12t - (6.50t + 150) > 0 => 5.50t > 150 => t > 150/5.50 => t > 27.27 => t>= 28 t- shirts;

hii, I think you forgot to add a question :)

at 8:03 am there are 188 empty seats on the train. at 8:10 am there are 160 empty seats. the number of seats decreases by the same amout each minute. (a)what equation can be used to relate the number of minutes after 8:00 am (M) to the number of empty seats on the train (E)? (b)how many seats will be empty at 8:15? (c)at what time will there be 120 empty seats? (d)at what time will there be no empty seats left ?

Answers

Given:
8:03 = 188 empty seats
8:10 = 160 empty seat

188 - 160 = 28 empty seats
8:10 - 8:03 = 0:07 minutes

28 / 7 minutes = 4 empty seats per minute

8:00 - 8:03 = 3 minutes
3 minutes * 4 seats per minute = 12 seats

188 + 12 = 200 empty seats at 8:00

8:15 - 8:10 = 0:05 minutes
5 minutes * 4 seats per minute = 20 empty seats
160 - 20 = 140 empty seats at 8:15

200 - 120 = 80 empty seats
80 empty seats / 4 empty seats per minute = 20 minutes
120 empty seats at 8:20.

8:00 = 200 empty seats
200 / 4 = 50 minutes
8:00 + 0:50 = 8:50 is the time when there are no empty seats left.

How do I solve this -4y+x=-27

Answers

First you have to know what a "solution" is.

The 'solution' is a set of 2 numbers which, if you put them into the equation
in place of 'x' and 'y', make the equation a true statement. 

There are an infinite number of possible pairs of numbers that can do that. 
Here are a few:

x = 0, y = 6.75 
x = 1, y = 7
x = 2, y = 7.25
x = 3, y = 7.5
x = 4, y = 7.75
x = 10, y = 9.25
x= 100, y = 31.75
x= -50, y = -5.75

When you graph this equation, the graph is a straight line without any ends.
Every point on the line is a solution to the equation, and you know how many
points there are on a line without ends . . . . .



According x variable;

-4y+x=-27\n \n \boxed{x=4y+27}

According y variable:

-4y+x=-27\n \n -4y=-27-x\n \n \boxed{y=(-27-x)/(-4)}

What is the side length of a cube with a volume of 3375 cm3

Answers

If you would like to know what is the side length of a cube with a volume of 3375 cm^3, you can calculate this using the following steps:

a ... side of a cube
V = a^3
3375 = a^3
a = 15 cm

The correct result would be 15 cm.
 The volume of a cube is given by V = s3, where s is the length of a side. Find the length of a side of a cube if the Volume is 1000 cm3.

What percent 591 is of 2364?

Answers

since percent means parts out of 100 then x/100=x%

the easy way is to do it is to divide 591 by 2364
591/2364=0.25
0.25/1 multiply by 100/100=25/100=25%

the answer is 25%

25% because you need to divide 591 by 2364 to get .25 then you move the decimal place over two to the right which gives you 25%!
