The prices of several inkjet cartridges and an estimate for the number of pages each will print are shown in the table. Based on the unit price per page, how much more will it cost to print a page using the MOST EXPENSIVE cartridge than using the LEAST EXPENSIVE cartridge?
A) 4¢
B) 7¢
C) 8¢
D) 10¢
Answer:
It will cost 4 cents to print a page using the MOST EXPENSIVE cartridge than using the LEAST EXPENSIVE cartridge .
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 .
The temperature drops 28°. After the drop, the thermometer reads 48°. Which integer represents the number of degrees the temperature drops?
Answer: The answer is -28
Step-by-step explanation:
Trust me
Final answer:
The integer representing the temperature drop of 28°, leaving the thermometer at 48°, is -28. The original temperature before the drop was 76°.
Explanation:
The integer that represents the number of degrees the temperature drops when the temperature drops 28° and the thermometer reads 48° afterwards is -28. To find this, we use the final temperature (48°) and add the temperature drop (28°) to determine the original temperature. However, since it is a temperature drop, we have to add a negative sign to the drop, making it -28°. Therefore, the original temperature was 48° + 28° = 76°. The decrease in temperature is represented by the negative integer -28°.

Answer:
Step-by-step explanation:50,897 is in standard form.
Expanded form is adding all your place values which is 50,000+800+90+7. There was a 0 in the thousand place so you do not add anything for that place value.
So (5×10,000) + (8×100) +(9×10)+(7×1) which is each number times it place value then add them all up.
Written form would be fifty thousand, eight hundred and ninety seven. So your answer is A, B, D

Solve for a:
3a +11 > 5
Subtract 11 from both sides:
3a >-6
Divide both sides by 3:
a > -6/3
a > -2
The Correct graph is the second one, because it has the dot on the -2 and the arrow points to the right
The 2 number line shows the solutions to the inequality 3a + 11 > 5 and the correct option is B.
The image shows two number lines, and asks which one shows the solutions to the inequality 3a + 11 > 5.
To solve this inequality, we can subtract 11 from both sides, and then divide both sides by 3. This gives us a simpler inequality: a > -2.
This means that all values of a that are greater than -2 are solutions to the inequality. On a number line, this can be represented by an open circle at -2, and an arrow pointing to the right.
The number line on the left of the image shows exactly this. Therefore, the number line on the left shows the solutions to the inequality 3a + 11 > 5.
The number line on the right of the image does not show the solutions to the inequality correctly. The open circle at -2 is missing, and the arrow points to the left, which is incorrect, since the solutions to the inequality are all values of a that are greater than -2, not less than -2.
Here is a more detailed explanation of the steps involved in solving the inequality:
1. Subtract 11 from both sides:
3a + 11 > 5
-11 - 11
3a > -6
2. Divide both sides by 3:
3a > -6
3 / 3
a > -6 / 3
3. Simplify:
a > -2
Therefore, the solution to the inequality is a > -2. On a number line, this can be represented by an open circle at -2, and an arrow pointing to the right.
The number line on the left of the image shows exactly this. Therefore, the 2 number line on the left shows the solutions to the inequality 3a + 11 > 5 and the correct option is B.

C. 0.75x + 0.8x + 10 = 101
D. 0.75x + 0.8(x + 10) = 101
Answer:
its d trust me
Step-by-step explanation:
Answer:
0.75x + 0.8(x + 10) = 101
Step-by-step explanation:
Write an expression to represent the number of shots each one made.
Jared attempted x shots and made 75% of them, or 0.75x.
Zach attempted 10 more shots than Jared did, which is represented as x + 10. He made 80% of them, or 0.8(x + 10).
Together, they made 101 shots. So, add the two expressions and set the sum equal to 101:
0.75x + 0.8(x + 10) = 101.

Which pipe configuration can deliver more water to
residents, one 8-cm pipe or two 4-cm pipes? Show your
work and explain your reasoning.
4 cm
8 cm
4 cm
Answer: One 8-cm pipe (Its is greater than the total area of of two 4-cm pipes)
Step-by-step explanation:
The area of a circle can be calculate with this formula:
[tex]A=\pi r^2[/tex]
Where "r" is the radius of the circle.
We need to calculate the area of 8-cm pipe. In this case:
[tex]r=8cm[/tex]
Then, substituting the radius into the formula, we get:
[tex]A=\pi (8cm)^2\\\\A=201.06cm^2[/tex]
Now we must calculate the area of the two 4-cm pipes.
Since they are two pipes, the formula is:
[tex]A=2\pi r^2[/tex]
In this case:
[tex]r=4cm[/tex]
Then, substituting into the formula, we get:
[tex]A=2\pi (4cm)^2\\\\A=100.53cm^2[/tex]
Therefore, since the area of one 8-cm pipe is greater than the total area of of two 4-cm pipes, we conclude that the pipe configuration that can deliver more water to residents is:
One 8-cm pipe
acme movers charges $150 plus $30 per hour to move household goods across town. hanks movers charges $55 per hour. for what lengths of time does it cost less to hire banks movers?
Answer:
For the length of time less than 6 hours cost less to hire Hanks movers
Step-by-step explanation:
Let
x -----> the time in hours
y ----> the total cost in dollars
we know that
Acme movers
[tex]y=30x+150[/tex] ----> equation A
Hanks movers
[tex]y=55x[/tex] ----> equation B
Equate equation A and equation B and solve for x
[tex]55x=30x+150[/tex]
[tex]55x-30x=150[/tex]
[tex]25x=150[/tex]
[tex]x=6\ hours[/tex]
That means-----> For x= 6 hours The cost in both companies is the same
Verify
For x=6 hours
Acme movers
[tex]y=30(6)+150=\$330[/tex]
Hanks movers
[tex]y=55(6)=\$330[/tex]
If x < 6 hours ----> It cost less to hire Hanks movers
If x > 6 hours ----> It cost less to hire Acme movers
therefore
For the length of time less than 6 hours cost less to hire Hanks movers

jonathan went for a jog. every time he stops to tie his shoelaces, his jog lasts 2 1/2 minutes longer. if he stops to tie his shoelaces four times, how much longer does his jog take
Final answer:
When Jonathan stops to tie his shoelaces four times, each adding 2 1/2 minutes, his jog takes an extra 10 minutes in total.
Explanation:
Jonathan stops to tie his shoelaces four times during his jog. Each time he stops, it adds 2 1/2 minutes to his total jog time. To find out how much longer his jog takes, we need to multiply the number of stops by the additional time per stop.
Let's calculate this step by step:
Convert the additional time per stop to an improper fraction, which is 5/2 minutes or 2.5 minutes.Multiply the number of stops, which is 4, by the additional time per stop, which is 2.5 minutes.The total additional time is 10 minutes (2.5 minutes/stop x 4 stops).So, if Jonathan stops to tie his shoelaces four times, his jog will take an extra 10 minutes in total.
Colleen divided integer “a” by -6 and got six. Then she divided six by integer B and got -3. Find the quotient of integer a and integer b
Answer: [tex]\frac{a}{b}= 18[/tex]
Step-by-step explanation:
You know that the quotient Colleen got when she divided an integer “a” by -6 was 6. This can be expressed as:
[tex]\frac{a}{-6}=6[/tex]
Then, you can find that integer solving for "a":
[tex]a=(6)(-6)\\\\a=-36[/tex]
The quotient Colleen got when she divided 6 by an integer “b” was -3. This can be expressed as:
[tex]\frac{6}{b}=-3[/tex]
Therefore, you can find that integer solving for "b":
[tex]6=(-3)(b)\\\\\frac{6}{-3}=b\\\\b=-2[/tex]
Knowing the values of "a" and "b", you can divide these integers in order to find the quotient between thenm
[tex]\frac{a}{b}=\frac{-36}{-2}}= 18[/tex]

Mike had 116 dollars to spend on 8 books. After buying them he had 12 dollars. How much did each book cost?
Answer:
each book costs $13
Step-by-step explanation:
Let the cost of each book be $x
cost of buying 8 books = $8x
It is given that with an original amount of $116, after buying 8 books, he had $12 left over. Hence,
$8x + $12 = $116 (dropping the $ signs)
8x + 12 = 116
8x = 116 - 12
8x = 104
x = 13 (each book costs $13)
Answer:
he possibly spent $13 on order to end up with $12 left.
Step-by-step explanation:
1) look. at the number 116 you can use a calculator.
2) if 14 only leaves you with nothing you take it away
3) add 13 + 8X that should give you 104
4). substract 116-104 your total should be $12

What is the image point of (2,8) after a translation left 3 units and up 1 unit?
Answer:
(- 1, 9 )
Step-by-step explanation:
A translation of 3 units left, subtract 3 from the original x- coordinate
A translation of 1 unit up, add 1 to the original y- coordinate.
The rule is (x, y ) → (x - 3, y + 1 ), thus
(2, 8 ) → (2 - 3, 8 + 1 ) → (- 1, 9 )
The image point of (2,8) is (-1,9).
What is the image point?The term P', which is pronounced "P prime," is used to refer to the reflection of point P across the line, which is considered to be the "image" of point P.
Given point is (2,8).
And the translation is left 3 unit and up 1units of the point (2,8)
