Answer:

Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opp}{100}[/tex] ( multiply both sides by 100 )
100 × tan35° = opp , that is
opp ≈ 100 × 0.7002 = 70.02
Thus height of tree = 70.02 + 5 = 75.02 ft
--------------------------------------------------------------------
Using the tangent ratio in the right triangle on the right.
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{25.17}{rope}[/tex] ( multiply both sides by rope )
rope × tan40° = 25.17 ( divide both sides by tan40° )
rope = [tex]\frac{25.17}{tan40}[/tex] = [tex]\frac{25.17}{0.839}[/tex] = 30 ft

What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given is Erin can read two chapters of her book in 1.5 hours and Erin's book has 33 chapters.
Two chapters of book → 1.5 hours of reading
one chapter of book → (1.5/2) hours of reading

the roaming sell phone company charge's 15.00 a month plus 0.20 per minute of airtime usage. if juanita uses x minutes of air time what is the equation that can be used to determine her monthly phone bill (c)?
Answer:
$63.00
Step-by-step explanation:
Since you have sales tax, you would do a 10% sales tax for 15 dollar
10/100 = x/15
Therefore you will calculate x and 100 divided by 15 which would be 6.6 repeated
You would round to the nearest tenth and get 6.6 then you would add 56.4 as in the tip+ month airtime usage and get 63 dollars.

Two students are having a party. They want to make treat bags for their guests. They want each bag to be identical with nothing leftover. They have 36 Silly Bandz and 72 pieces of Double Bubble to put in the bags. What is the greatest number of treat bags they can make? How many of each item will be in each treat bag?
Answer:
Two students can make maximum 36 treat bags.
Number of pieces of silly Bandz in each bag [tex]=1[/tex]
Number of pieces of Double Bubble in each bag [tex]=2[/tex]
Step-by-step explanation:
Number of pieces of silly Bandz = 36
Number of pieces of Double Bubble = 72
To find greatest number of treat bags that they can make, find H.C.F. of 36 and 72
[tex]36=(2^2)(3^2)\\72=(2^3)(3^2)[/tex]
[tex]H.C.F(36,72)=36[/tex]
So,
they can make maximum 36 treat bags.
Number of pieces of silly Bandz in each bag [tex]=\frac{36}{36}=1[/tex]
Number of pieces of Double Bubble in each bag [tex]=\frac{72}{36}=2[/tex]

-2 4
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.

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.
