B. It is better to overestimate so the coach can buy more golf balls than he originally plans.

O
Answer:
A
Step-by-step explanation:
The coach will most likely count this as an expense and will want to overestimate so that he is certain to have all the golf balls for his lessons. If he underestimates, he will not be able to have all his balls.
A. It is better to overestimate to make sure the coach has enough money to buy the golf balls.
What is over and under estimating ?Over estimating is when we set a higher amount than we need in case of price increase and the item is a must buy.
Underestimating when we set a lower amount than needed when money is of more concern and the item is not a must buy.
According to the given question At the beginning of the season, a golf coach buys 118 sleeves of golf balls. Each sleeve costs $8.
It is always better to overestimate and if some amount remains then it can be used later.
So, It is better to overestimate to make sure the coach has enough money to buy the golf balls to continue his lessons without any interruption underestimating will lead to less golf balls and interrupted golf sessions.

Answer:
You meant 1 1/2. Answer : Y intercept
Step-by-step explanation:
The slope of the line on the graph as per the given scenario is 2.
What is Graph?In mathematics, a graph is a visual representation of a set of data or mathematical relationships.
Graphs are used to show the relationship between two or more variables and can be represented in a variety of formats, including line graphs, bar graphs, scatter plots, and more.
To find the slope of a line, we need to determine how much the y-value changes for every 1-unit increase in the x-value. Looking at the graph, we can see that the line passes through the points (1, 2) and (2, 4).
To find the slope, we can use the slope formula:
slope = (change in y) / (change in x)
If we let (x1, y1) = (1, 2) and (x2, y2) = (2, 4), then the slope is:
slope = (y2 - y1) / (x2 - x1)
slope = (4 - 2) / (2 - 1)
slope = 2
Therefore, the slope of the line on the graph is 2.

You are a contractor and charge $45 for a site visit plus an additional $24 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $117 working at two separate work sites. Write an equation to describe the situation. Use h to represent the number of hours.
Please help asap and thanksss
Answer:
y = mx + b
where,
y = earning
m = slope or earning per hour = $24
x = total number of hours
b = y intercept or initial earning upon visit = $45
Hence,
y = 24x + 45
Since we are working at two separate work sites, therefore each site we must earn 810/2 = 405
So when y = 405:
405 = 24x + 45
x = 15 hours
So you must work 15 hours at each site.
Step-by-step explanation:
Answer:
7.56 hours.
Step-by-step explanation:
So my equation will be:
$45 + $24h
If we need to find out how many hours you have to work in order to earn $117 working at two separate work sites, the equation would look like this:
45 + 25h ÷ 2 = 117.
First we need to multiply both sides of th equation by 2.
[tex]\frac{2\left(45+25h\right)}{2}=117\cdot \:2[/tex]
Then, I had to simplify.
[tex]5+25h=234[/tex]
After simplifying, it was about time to subtract 45 from both sides of the equation.
[tex]45+25h-45=234-45[/tex]
I had to simplify again, then divide both sides by 25.
[tex]25h=189[/tex]
[tex]\frac{25h}{25}=\frac{189}{25}[/tex]
Again, I have to simplify for a final time to get the answer of..
[tex]h=\frac{189}{25}[/tex]
In decimal form, thats equal to 7.56 hours.
h = 7.56.
