Although it is impossible to send mail to 1.2 homes in a minute, Mark's solution is valid since 1.2 corresponds to the unit rate of homes per minute.
What is the mark's method?When reset() is performed, the stream is marked as the checkpoint from which the stream read will begin in Java by using the mark() function of the Reader class.
Option 1: Mark's approach is incorrect since there is no way to distribute mail to 1.2 homes in a minute. Only a certain amount of homes can get deliveries from the carrier.
This is untrue because the rate of 1.2 just indicates that the carrier may complete one house in a minute while still having time to begin delivering to the second residence. While the rate is not required, the total number of houses must be a whole number.
Option 2: Mark's approach is incorrect since mail cannot be delivered for 7.5 minutes. Mail delivery by the carrier is limited to a set number of minutes.
Furthermore erroneous is this choice.
Option 3: Mark's approach is accurate because, not with standing the impossibility of delivering mail to 1.2 homes in a minute, 1.2 corresponds to the average number of homes every minute.
This choice is the best one. The mail is delivered by the carrier at a rate of 1.2.
Option 4: Mark's approach is accurate because he can deliver mail for 7.5 minutes, which corresponds to the unit rate of 7.5 minutes per dwelling.
Furthermore erroneous is this choice. Although it is feasible to transport mail for 7.5 minutes, this is the overall time required, not the unit rate.

Complete question is" A mail carrier can deliver mail to 36 houses in 30 minutes. Mark wants to determine how many houses the carrier can deliver mail to in 7.5 minutes at this rate. He thinks that to find the answer, he should do the following. 1. First divide 36 houses by 30 minutes to find a unit rate of 1.2 houses per minute. 2. Then multiply 1.2 houses per minute by 7.5 minutes to get 9 houses. Which statement is correct? Mark’s method is wrong, because it is impossible to deliver mail to 1.2 houses in a minute. The carrier can only deliver to a whole number of houses. Mark’s method is wrong, because it is impossible to deliver mail for 7.5 minutes. The carrier can only deliver mail for a whole number of minutes. Mark’s method is correct, because even though it is impossible to deliver mail to 1.2 houses in a minute, 1.2 represents the unit rate of houses per minute. Mark’s method is correct, because it is possible to deliver mail for 7.5 minutes; 7.5 represents the unit rate of 7.5 minutes per house."

The price of Apple stock, A(X), over a 12 month period decreased and thenincreased according to the equation A(x) = x x 0, where x equals the number ofmonths. The 2 - 6 + 2 price of Baller stock B(x), increased according to theequation B(x) = 3x + 2 over the same 12-month period. When were both stockvalues the same?
The question is: When we're both stock values the same? Then all you have to do is match both equations and solve for x, like this
[tex]\begin{gathered} A(x)=x^2-6x+20 \\ B(x)=3x+2 \\ \text{ Matching you have} \\ x^2-6x+20=3x+2 \\ \text{Subtract 3x from both sides of the equation} \\ x^2-6x+20-3x=3x+2-3x \\ x^2-9x+20=2 \end{gathered}[/tex][tex]\begin{gathered} \text{Now subtract 2 from both sides of the equation} \\ x^2-9x+20-2=2-2 \\ x^2-9x+18=0 \end{gathered}[/tex]Factoring the trinomial you get
[tex]x^2-9x+18=(x-6)(x-3)=0[/tex]Which implies that
[tex]\begin{gathered} x-6=0 \\ x=6 \\ \text{ or} \\ x-3=0 \\ x=3 \end{gathered}[/tex]Therefore, since x corresponds to the number of months, then the values of the two shares were equal at 3 and at 6 months.

Answer:
x = 23
y = 119
Step-by-step explanation:
Line m is parallel to line n and the angle given as 61 and the angle that is represented with 4x - 31 are alternate angles and have equal measurement.
We can write the following equation based on this information:
4x - 31 = 61 add 31 to both sides
4x = 92 divide both sides by 4
x = 23
now onto y,
the angle represented with y and the angle that is represented with 4x - 31 are supplementary and their measures add up to 180:
4x - 31 + y = 180 replace x with 23
4*23 - 31 + y = 180
92 - 31 + y = 180 subtract like terms
61 + y = 180 subtract 61 from both sides
y = 119

Mia has set up a lemonade stand outside her house and sells small cups and large
cups of lemonade. Each small cup holds 12 ounces of lemonade and each large cup
hold 22 ounces of lemonade. Mia sold 80 cups of lemonade totaling 1460 ounces.
Determine the number of small cups sold and the number of large cups sold.
Answer:
small cups: 30large cups: 50Step-by-step explanation:
You want the number of small (12 oz) cups and large (22 oz) cups sold if 80 total cups and 1460 ounces were sold.
SetupWe can let x represent the number of large cups sold. Then 80-x is the number of small cups sold, and the total ounces of lemonade sold are ...
12(80 -x) +22x = 1460
SolutionSimplifying the equation gives ...
960 +10x = 1460
10x = 500
x = 50
Then the number of small cups sold is ...
80 -x = 80 -50 = 30
30 small cups and 50 large cups were sold.

sodas cost $13.75. Is the cost a proportional or
non-proportional relationship?
proportional
not enough information
non-proportional
The cost for the soda is proportional.
How to calculate the value?For there to be a proportional relationship, there must be a constant.
In this case, one soda costs $2.75.
Also, five sodas cost $13.75. The cost per soda will be:
= $13.75 / 5
= $2.75
Since the values of $2.75 are the same, it has a proportional relationship.

Choose the line perpendicular to the following equation through the given point
Answer:
y=-1/2x+1
Step-by-step explanation:
perpendicular is when the gradient of the existing equation is reciprocated (swapped sides and flipped)
new gradient- -1/2
so our new equation is y=-1/2x+c
we have the co-ordinates for x and y so substitute into new equation
1=(-1/2 x 0) + c
so c=1
Hence our equation is : y=-1/2x+1

Henry goes to the town fair.Use the prices on the photograph to complete the table.Enter the correct answer in the box.
ANSWER
$28
EXPLANATION
We have that the entry fee is $10 and for each ride, $6 must be paid.
We want to complete the table by finding the cost of 3 rides.
First, let us represent the cost of going to the fair and taking the ride.
Let the number of rides a person takes by x.
We have that the cost of taking x rides will be the entry fee plus the cost of each ride taken:
Cost = 10 + 6x
So, for taking 3 rides, it will cost:
Cost = 10 + 6(3)
Cost = 10 + 18
Cost = $28
That is the cost of taking 3 rides.

A jar contains only pennies, nickels, dimes, and quarters. There are 28 pennies, 26 dimes, and 23 quarters. The rest of the coins are nickels. There are 90 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
If n represents of nickels in the jar, then the equation that can be used to find n is; n + 77 = 90
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Assume that n represent the number of nickels in the jar.
Given that the jar contains only , pennies, nickels, dimes, and quarters. There are 28 pennies, 26 dimes, and 23 quarters. The rest of the coins are nickels.
This means that the total number if pennies, dimes and quarters would be;
23 + 28 + 26 = 77
This means that the number of coins that are not nickel = is 77
The total number of coins in the jar is 90. Therefore, the equation that can be used to find n is;
n + 77 = 90
n = 90- 77
