Jason had $284.31 on his student lunch account at the beginning of the school year. During the year, he mowed lawns for extra money to add to his lunch account. He mowed 13 lawns and earned $30 for each lawn. By the end of the school year, he had spent $782.75 on his lunches. What was the balance in Jason’s account at the end of the school year?
Answers
Answer:
$-108.44
Step-by-step explanation:
Hey! Let's help you out with this question!
We always want to begin with what we know. We know that Jason has $284.31 on his lunch account and that during the year he mowed 13 lawns and earned $30 for each lawn. By the end, he spent $782.75 and now we need to figure out what his balance was at the end of the year. This can be split into 2 parts:
Part 1:
Let's start by how much money he has in total. We can take the current balance in his account of $284.31 and add the amount of money he made mowing lawns. We know that he mowed 13 lawns and earned $30 for each lawn. So, we can just chalk that total to be:
\(13*30=390\)
Based on our calculation, we know that he has earned $390 in total from mowing 13 lawns for $30 each lawn. Now that we have that, let's add that earning into his current balance and that'll give us:
\(284.31+390=674.31\)
Therefore, in total Jason has $674.31. including how much he earned from mowing lawns.
Part 2:
Now, we need to figure out Jason's account balance at the end of the school year. From here, we take the new total of Jason's account balance and subtract it from how much he spent on lunches throughout the school year. So, it would look like this:
\(674.31-782.75=-108.44\)
Unfortunately, Jason has spent too much on his lunches and his account balance at the end of the school year is $-108.44

A garden hose was left on in a yard and spilled 78 gallon every 23 minute. Find the average number of gallons spilled per minute.
Answers
Answer:
3.391 Gallons Per Minute
Step-by-step explanation:
78/23=3.391
Round 3.391 to 3.4
Answer:
≈3.39130434783 gallons per minute
Step-by-step explanation:
The information we get is a ratio, describing how many gallons of water will be wasted in 23 minutes, expressed as:
\(78 : 23\) OR \(\frac{78}{23}\)
We will use the fraction, the denominator is representing the time, which in this case, is 23 minutes. We want to have the denominator as 1 to find how much water will be spilled in one minute, to do this, we can divide both the numerator and denominator by 23:
\(\frac{78/23}{23/23} \\ =\frac{3.39130434783...}{1}\)
And of course, if there's a need to round, go ahead.
And please do not waste water!

Laura is training to run a race. She keeps track of the number of miles she runs. She has been training for 7 weeks, and she has run a total of 63 miles. At what rate has she been running, in miles per week?
Answers
Explanation:
You divide the two values given to get 63/7 = 9.
We can think of it as if it was a ratio 63 miles: 7 weeks. Dividing both parts of that ratio by 7 will turn the "7 weeks" into "1 week".
You can check the answer by multiplying the 9 miles per week with the 7 weeks to get 9*7 = 63 miles total.

Describe a rule for determining how much the store charges based on the number of turkey subs delivered.
Answers
The rule for determining how much the store charges based on the number of turkey subs delivered will depend on the pricing structure that the store uses. One possible rule is a linear function, where the cost of each turkey sub is a fixed amount and the total cost is proportional to the number of subs delivered.
For example, if the store charges $5 for each turkey sub, the rule could be:
Total cost = $5 per sub * Number of subs delivered
So if the store delivers 10 turkey subs, the total cost would be:
Total cost = $5 per sub * 10 subs = $50
If the store delivers 20 turkey subs, the total cost would be:
Total cost = $5 per sub * 20 subs = $100
This rule assumes that the cost per sub remains constant regardless of the number of subs delivered. However, in reality, the cost per sub may vary depending on factors such as the cost of ingredients and labor, and the store's desired profit margin.
If ABC is reflecting across the y-axis ,what are the coordinates of c’?
Answers
Explanation:
First step is to locate point C. It is at location (6, 3)
Reflecting this over the y axis will change the sign of the x coordinate, while keeping the y coordinate the same. We go from (6, 3) to (-6, 3)
The algebraic rule for this is \((x, y) \to (-x,y)\)
Therefore, point C' is located at (-6, 3)

Tokens are put on some squares of an 8 x 8 grid to make a pattern, such as the one shown in the first diagram (without arrows.
We try to remove the tokens in a sequence of clearing steps. A clearing step consists of choosing row or a column which only contains 1 or 2 tokens and removing them. For example, we cannot initially remove all tokens from Column D. But we can clear Row 5 and then, in some later step, remove the two remaining tokens in column D.
If all the tokens in a oattern can be removed from the grid using some sequence of clearing steps, the pattern is called clearable. The pattern in the diagram is clearable because we can remove all tokens using the following sequence of 13 steps (among other possibilites) :
2, E, 8, G, 7, F, D, 5, 6, 3, 4, A, 1.

For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.

The length of a rectangular fenced enclosure is 12 feet more than the width
If farmer Dan has 100 feet of fencing, find the dimensions of the rectangle with the largest perimeter that can be created using 100 feet of fencing.
Answers
width = 19 ft
Assume that the width of the rectangle is w.
We are given that the length is 12 ft more than the width. This means that the length of the rectangle is w + 12
The perimeter of the rectangle in this case would be:
perimeter = 2 (length + width)
perimeter = 2 (12 + w + w)
perimeter = 24 + 4w
Assume that Dan would use all 100 ft of fencing to surround the yard. This would mean that the largest perimeter is 100 ft.
Therefore:
perimeter = 24 + 4w
100 = 24 + 4w
4w = 100 - 24
4w = 76
w = 19 ft
Since we have calculated that the width of the yard is 19 ft, we can substitute to get the length as follows:
length = 12 + w
length = 12 + 19
length = 31 ft
Answer:
length = 31 ft
width = 19 ft

The scatter plot below shows the average traffic volume and average vehicle speed on a certain freeway for 50 days in 1999.

As traffic volume increases, vehicle speed decreases at first, then increases.
As traffic volume increases, vehicle speed increases.
As traffic volume increases, vehicle speed decreases
Answers
Traffic Volume and vehicle speed are negatively correlated that means that as the traffic volume increases , the vehicle speed will decrease.
What is negative correlation in scatter plot?When the points in the scatter plot are in the pattern of falling from left to right it means the data is negatively correlated ,It means that the value of one variable decreases when the value of another variable increases.
Or we can say that the variable over x axis increases then variable for y - axis decreases.
As shown in the scatter plot in the question , we can that the points are falling from left to right , therefore there must be negative correlation
between Average traffic Volume And Average Vehicle speed.
Therefore, as the traffic volume increases , the vehicle speed will decrease.
