Step-by-step explanation:
Cartridge Price Printed Pages
Cartridge A $36.00 300
Cartridge B $67.50 450
Cartridge C $70.00 500
Cartridge D $66.00 600
Cartridge E $84.50 650
Cost of printing 300 pages with Cartridge A = $36
Cost of printing 1 page with Cartridge A = [tex]\frac{36}{300}=0.12[/tex]
Cost of printing 450 pages with Cartridge B = $67.50
Cost of printing 1 page with Cartridge B= [tex]\frac{67.50}{450}=0.15[/tex]
Cost of printing 500 pages with Cartridge C = $70
Cost of printing 1 page with Cartridge C = [tex]\frac{70}{500}=0.14[/tex]
Cost of printing 600 pages with Cartridge D = $66
Cost of printing 1 page with Cartridge D = [tex]\frac{66}{600}=0.11[/tex]
Cost of printing 650 pages with Cartridge D = $84.50
Cost of printing 1 page with Cartridge D = [tex]\frac{84.50}{650}=0.13[/tex]
Based on the unit price per page most expensive cartridge B and least expensive cartridge is Cartridge D.
So, Difference between the unit price of most expensive cartridge B and least expensive cartridge is Cartridge D = $0.15-$0.11 = $0.04
$1 = 100 cents
$0.04 = 4 cents
Hence it will cost 4 cents to print a page using the MOST EXPENSIVE cartridge than using the LEAST EXPENSIVE cartridge .

explain how reading the digits ro the right of the decimal point and knowing the name of the least place value help yoi read a decimal number.use examples .604 and 1.604 in your explanation
Final answer:
Reading decimal numbers requires understanding the places to the right of the decimal point: tenths, hundredths, thousandths, etc. The least significant place value—which in 0.604 is the thousandth place—helps in reading, rounding, and performing operations like moving the decimal point or using scientific notation.
Explanation:
Understanding how to read decimal numbers is important in mathematics. When reading the digits to the right of the decimal point, the name of each place value position helps you determine the value of the digit. For example, in the number 0.604, the digit '6' is in the tenth place, which means it represents six tenths, the digit '0' is in the hundredth place, acting as a placeholder, and the '4' is in the thousandth place, representing four thousandths. Similarly, in 1.604, the '1' is in the ones place, the '6' is in the tenth place, the '0' is a placeholder in the hundredth place, and the '4' is in the thousandth place.
Knowing the least place value is also important when rounding or when dealing with operations that affect the decimal point. For instance, if we need to move the decimal point or deal with scientific notation, recognizing the least significant digit's place value informs us how to maintain numerical accuracy. If you understand that the least significant digit in 1.604 is the '4' in the thousandth place, you would keep the decimal up to three places if you were to round or shift the decimal in calculations.

31. The bus fare in a city is $1.25. People who use the bus
have the option of purchasing a monthly discount pass for
$15.00. With the discount pass, the fare is reduced to $0.75.
Determine the number of times in a month the bus must
be used so that the total monthly cost without the discount
pass is the same as the total monthly cost with the discount pass.
The bus must be used 30 times in a month for the total monthly cost without the discount pass to be the same as the total monthly cost with the discount pass.
Explanation:The mathematical problem deals with determining the number of times one must take a bus ride for a monthly discount pass to be as cost-effective as individual fare payments. To solve it, we must set up an equation based on the cost of bus rides. Let's denote the number of bus rides as 'n'.
Without the pass, each ride is $1.25, so n rides would cost 1.25n dollars.
With the pass, each ride is $0.75 and you also need to pay $15 for the monthly pass, so n rides would cost 0.75n + 15 dollars.
To find out the break-even point, we set these two expressions for the total cost equal to each other:
1.25n = 0.75n + 15
Solving this equation gives us:
0.5n = 15, n = 15/0.5 = 30.
Therefore, the bus must be used 30 times in a month for the total monthly cost without the discount pass to be the same as the total monthly cost with the discount pass.

Nat’s grocery bill was $150, which includes a 5% club discount. What was nats bill before the discounts
Answer:
$157.89
Step-by-step explanation:
The original price is x
you took away 5%, making the new price 95% of x, or .95x
Put it in an equation
.95x = 150
x = 150/.95
x = 30/.19
x = 3000/19
x=157 17/19
x is about $157.89
The amount Nat's paid at the club before the discount is $157.90
Given:
Total bill including discount = $150
Discount = $5
Amount before discount = x
Total bill including discount = Amount before discount - (Discount × Amount before discount)
150 = x - (5% × x)
150 = x - (0.05 × x)
150 = x - 0.05x
150 = 0.95x
divide both sides by 0.95
x = 150 / 0.95
x = 157.89473684210
Approximately,
x = $157.90
Therefore, amount Nat's paid at the club before the discount is $157.90

5. Point M is the midpoint of segment AB. The coordinates of
point A are (-8, 3) and the coordinates of M are (-2, 1).
What are the coordinates of point B?
Answer:
(4, -1)
Step-by-step explanation:
Since it takes negative two to get from 3 to 1, you also have to deduct 2 from 1, which is -1 [y-coordinate]. Now, since it takes six to get from -8 to -2, you also have to add 6 to -2, which is 4 [x-coordinate].
So, point B is (4, -1).

find the equation of the horizontal line that contains the point (-4,8). express the equation using either the general form of the slope intercept form of the equation of a line
Answer: [tex]y=8[/tex]
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
[tex]y=mx+b[/tex]
Where "m" is the slope and "b" is the y-intercept.
We know that this is a horizontal line. This means that:
[tex]m=0[/tex]
Knowing that this line contains the point (-4,8) we can substitute this coordinates and [tex]m=0[/tex] into [tex]y=mx+b[/tex], and then solve for "b":
[tex]8=0(-4)+b\\\\b=8[/tex]
Therefore, the equation of this line in Slope-intercept form is:
[tex]y=(0)x+8\\\\y=8[/tex]
Final answer:
The equation of the horizontal line that contains the point (-4,8) is y = 8 and it demonstrates that for a horizontal line, the slope is 0 and the y-coordinate remains constant along the line.
Explanation:
The equation of a horizontal line that contains a given point can be determined by looking at the y-coordinate of that point. Since a horizontal line has a slope of 0, the y-coordinate of any point on the line does not change. Therefore, the equation of the horizontal line that contains the point (-4,8) is simply y = 8. This equation indicates that the y-value will always be 8, regardless of the x-value, which is characteristic of a horizontal line. In the slope-intercept form of the equation of a line, which is y = mx + b, the slope (m) is 0, and the y-intercept (b) is 8.

Find Sn for the given arithmetic series.
a1 = 18, d = –3, n = 14
Answer:
- 21
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ], thus
[tex]S_{14}[/tex] = [tex]\frac{14}{2}[/tex][( 2 × 18) + (13 × - 3) ]
= 7 (36 - 39) = 7 × - 3 = - 21
The sum of the arithmetic series with the first term 18, common difference -3, and 14 terms is 231.
Explanation:To find the sum, Sn, of an arithmetic series where a1 is the first term, d is the common difference, and n is the number of terms, you can use the formula:
Sn = ⅓n × (a1 + an)
First, find the nth term (an) using the formula:
an = a1 + (n - 1)d
For a1 = 18, d = –3, and n = 14:
an = 18 + (14 - 1)(-3)
an = 18 - 39 = –21
Sn = ⅓(14) × (18 + (–21))
Sn = 7 × (18 - 3) × 33
Sn = 231
So, the sum of the series is 231.

As lucia fills her fish tank, she notices that it fills 8 cubic centimeters of water in 4 minutes. How many cubic centimeters of water does it fill in 1 minute?
Answer:
2 cubic centimeters per minute
Step-by-step explanation:
8 cubic centimeters filled per 4 minutes
divide 8 by 4 = 2
2 cubic centimeters per minute
Answer: 2 cubic centimeters
Step-by-step explanation:
Given : As lucia fills her fish tank, she notices that it fills 8 cubic centimeters of water in 4 minutes.
i.e. Time taken to fills 8 cubic centimeters of water = 4 minutes
By UNITARY METHOD, we have
Amount of water it fills in 1 minute (i.e. Unit rate) = [tex]\dfrac{\text{8 cubic centimeters }}{\text{4 minutes}}[/tex]
= [tex]\dfrac{8}{4}=2[/tex] cubic centimeters
Therefore, it fills 2 cubic centimeters in 1 minute.
Hence, the correct answer is 2 cubic centimeters.

Answer:
[tex]y> \frac{2}{3}x+3[/tex]
Step-by-step explanation:
we have the points
(-3,1) and (0,3)
step 1
Find the slope m of the line
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
substitute the values
[tex]m=\frac{3-1}{0+3}[/tex]
[tex]m=\frac{2}{3}[/tex]
step 2
Find the equation of the line in slope intercept form
[tex]y=mx+b[/tex]
we have
[tex]m=\frac{2}{3}[/tex]
[tex]b=3[/tex] ----> the y-intercept is the point (0,3)
substitute the values
[tex]y=\frac{2}{3}x+3[/tex]
step 3
Find the equation of the inequality
we know that
The slope is positive
Everything to the left of the line is shaded ( The inequality is of the form y > ax+b or y ≥ ax+b)
Is a dashed line (The inequality is of the form y > ax+ b or y < ax+b)
therefore
The equation of the inequality is of the form y > ax+b
The inequality is
[tex]y> \frac{2}{3}x+3[/tex]
