A sporting goods store charges $30 for 12 cans of tennis balls and $45 for two boxes of golf balls. A coach orders 100 cans of tennis balls and 5 boxes of golf balls. How much will the coach pay for the tennis and golf balls?

Answers

Answer 1
Answer: tennis ball
12 cans = $30
1 can = $ 30/12 = $2.5

golf balls
2 boxes = $45
1 box = $45 /2 = $ 22.5

100 cans of tennis balls + 5 boxes of golf boxes 
(100 * $ 2.5)  + ( 5 *  $ 22.5) 
$250 + $112.5
$362.5

How do you put 5/2 on a number line

Answers

Convert 5/2 to a mixed number first:  

Divide 5 by 2; 2 will go into five 2 times with a remainder of 1.  This means the whole number portion of the mixed number is 2, and the remainder of the fraction is 1; this gives us 2 1/2.

To plot 2 1/2, plot a point halfway between 2 and 3.

By following steps given, you can successfully placed the fraction 5/2 on the number line.

To put the fraction 5/2 on a number line, you can follow these steps:

1) Draw a straight line horizontally on a piece of paper or use a number line chart if available. Make sure the line is long enough to accommodate the desired range.

2) Determine the range you want to represent on the number line. Let's say you want to represent the numbers from 0 to 3.

3) Divide the line into equal segments to match the range you determined.

For example, you can divide the line into four equal segments representing the numbers 0, 1, 2, and 3.

4) Locate the whole number part of the fraction, which is 2 in this case. Place a point or tick mark above the number 2 on the number line.

5) Divide the segment between the whole numbers into equal parts. Since the fraction is 5/2, you need to divide the segment between 2 and 3 into two equal parts.

6) Starting from the point above the number 2, count two equal segments to the right.

Place a tick mark or point at the end of the second segment.

7) Label this point with the fraction 5/2.

The graph of a line passes through the points (0, -2) and (6.0). What isthe equation of the line?

Answers

Answer:

y=(1)/(3)x-2

Step-by-step explanation:

The equation of a line is given in the form  y=mx+b

Where

m is the slope with formula  m=(y_2-y_1)/(x_2-x_1)

and

b is the y-intercept [y axis cutting point of line]

Given the two points (0, -2) and (6,0),

x_1 = 0

y_1 = -2

x_2 = 6

y_2 = 0

Now, we find m using formula:

m=(0+2)/(6-0)=(1)/(3)

Now we have

y=(1)/(3)x+b

Finding b, we plug in any (x,y) point. Lets put (6,0) and find b:

y=(1)/(3)x+b\n0=(1)/(3)(6)+b\n0=2+b\nb=-2

Thus,

equation of line = y=(1)/(3)x-2
