Joe is 6 A tall, and stands 30 ft away from a pole. If his line of sight to the top is at a 40° angle above the
horizontal approximately how tall is the pole?
Answer:
Height of pole =
31 feet
Step-by-step explanation:
Here, we are to calculate the height of the pole.
Please check the attachment for diagrammatic representation of the question.
We use trigonometric ratio to calculate the length AC first.
The ratio to use here is Tan
This is because we have the adjacent and we want to calculate the opposite
Mathematically;
Tan of an angle = length of opposite/length of adjacent
Tan 40 = AC/30
AC = 30Tan 40 = 25.17 which is approximately 25 feet
The height of the pole is the length CE + AC
CE = BD = 6 ft since they are opposite sides of rectangle BCDE
The height of the pole is thus 6 + 25 = 31 feet approximately

Find the value ox x. (Circles)
Answer:
x = 140 degrees
Step-by-step explanation:
Lets say that the other part of the circle we don't know is y. Because the chords are equal distance, that means that the amount of circle the cut off is equal so y also equals 100.
And y + x + 100 + 20 = 360
100 + x + 100 + 20 =360
x + 220 = 360 Subtract 220 from both sides.
x = 140

Step-by-step explanation:
Kia is saving money to buy a Six Flags ticket. She worked for 6 hours at the library and earns the same amount each hour. Her grandmother then gave her $20. In all,she has $53.
Answer:
She earns 5.5 dollars per hour at the library
Step-by-step explanation:
I am going to assume that the questions is "how much she earns per hour at the library?"
Let's call x the amount of dollars earn by hour at the library. We know that she worked for 6 hours, thus she made 6x dollars.
Later her grandma gave her 20 dollars and she has now 53 dollars.
Let's write the equation and solve it
Amount earned + Amount given by her grandma = 53
[tex]6x+20=53\\6x=33\\x=\frac{33}{6}\\x=5.5[/tex]
Thus, based on this information we would have that Kia earns 5.5 dollars per hour.
A grid shows the positions of a subway stop and your house. The subway stop is located at (7,3) and your house is located at (4-5). What is
the distance, to the nearest unit, between your house and the subway stop?
Answer:
9 units
Step-by-step explanation:
In a coordinate plane with point P( x , y) and Q(a,b ).
distance between these are points is given by equation
distance between PQ = [tex]\sqrt{(x-a)^2 + (y-b)^2}[/tex].
Coordinate of subway stop = (7,3)
Coordinate of house = (4-5)
Therefore using the above the formula to calculate distance between
house and the subway stop is given by
distance = [tex]\sqrt{(7-4)^2 + (3-(-5)^2}\\\\=>\sqrt{(3)^2 + (3+5)^2}\\\\=>\sqrt{9 + (8)^2}\\\\=>\sqrt{9 + 64}\\\\=>\sqrt{9 + 64}\\\\=>\sqrt{73}\\\\=>8.544[/tex]
Therefore, distance between house and the subway stop is 8.544 units.
But it is given that distance should be to the nearest unit.
any decimal value greater than or equal to .5 is equivalent to 1 in nearest unit.
Thus, 8.544 units is equivalent to 9 units (in nearest unit)

Greg plans to purchase a bicycle. Bike A costs $270 and has an expected maintenance cost of $36 per year. Bike B costs $360 and has an expected maintenance cost of $20 per year. Which statement is true based on the average annual cost of each bike?
Answer:
Bike A costs $270 and has an expected maintenance cost of $36 per year."Bike A is the better choice if Greg plans on owning the bike for 5 years. Bike B is the better choice if Greg plans on owning the bike for 6 years."Step-by-step explanation:
270-36x
there are 5 years so x=5
270 + 36(5) = 270 + 180 = 450
If it were 6 years than x = 6
270 + 36(6) = 270 + 216 = 486
Bike B:
360 + 20x
For option b x = 5
360 + 20(5) = 360 + 100 = 460
for option b it would be 6 years than x = 6
360 + 20(6) = 360 + 120 = 480
Hope i helped!This cost function of purchasing a bike A
[tex]\to f1(x) = 270+ 36 x[/tex] ( The unit of x is a year)
A cost function for purchasing bike B:
[tex]\to f2(x) = 360+20x \\\\if \ \ f1(x)<f2(x)\\\\ \therefore\\\\ \to 270+36x-360+20x\ \ \ (transpose)\\\\\to 16x= 90 \\\\\to x=\frac{90}{16}=5.625\\\\[/tex]
If Greg plans to keep the bike for 5 years, Bike A is the superior option. If Greg plans to keep the bike for 6 years, Bike B is the superior option.

a) f(x) = -⅙(x+3)²+6
b) f(x)=-⅙(x-3)²+6
c) f(x) = -6 (x+3)² +6
d) f(x) = -6 (x-3)² + 6
Answer:
a.) f(x) = -⅙(x+3)²+6
Step-by-step explanation:
The maximum value, our vertex, is at point (-3,6).
We can insert this value into the vertex form of a quadratic function and then solve for a as follows...
[tex]4.5 = a(0 +3)^2 +6\\4.5=a(9)+6\\-1.5 = 9a \\-.17=a\\a = -1/6[/tex]
a equals -1/6... We can input this into the original equation we used...
f(x) = -1/6(x+3)^2+6

Answer:
8.66 meters
Step-by-step explanation:
Assuming that the building is completely straight, a right angle is formed and therefore a right triangle.
Thanks to this we can calculate the height at which the ladder reaches the wall using the Pythagorean theorem, this height being one of the legs.
We have to:
c ^ 2 = a ^ 2 + b ^ 2
c = 10
a = 5
replacing
b ^ 2 = 10 ^ 2 - 5 ^ 2
b ^ 2 = 75
b = 8.66
that is to say that the height at which the ladder reaches the wall is 8.66 meters

Step-by-step explanation:
A local charity organization held an event to celebrate its work for the past five years. A local newspaper reporter who attended the event asked 75 of the attendees about their contributions. The reporter computed the mean amount of money raised by the 75 attendees to be $18,500. In an article published by the local newspaper, the reporter was quoted as stating, "The members of the charity organization were successful in raising money for their cause. Last year, they raised a mean amount of $18,500!"
Part A: What is a statistical advantage of using the median of the reported amounts, rather than the mean, as the estimate of the typical amount raised? (4 points)
Part B: The newspaper editor felt the individuals who attended the event may be different from the organization as a whole. A more detailed survey of the members was planned to determine a better estimate of the amount of money raised. The staff developed two methods based on the available funds to carry out the survey.
Method 1: Send out an e-mail to all 10,530 members of the organization and ask them to complete an online form. The staff estimates at least 2,000 members will respond.
Method 2: Select a simple random sample of members of the organization and contact the selected members directly by phone. Follow up to ensure all responses are obtained. Because method 2 requires more time than method 1, the staff estimates that only 1,000 members of the organization can be contacted using method 2.
Which of the two methods would you select for estimating the average yearly amount raised by all 10,530 members of the charity organization? Explain your reasoning by comparing the two methods and by describing the effect of each method on the estimate.
Answer:
Part A. The statistical advantage of using the median is that the median is less effected by skewed data and outliers.
Part B. I would select method two because method one has a non-response bias and the sample individuals are not selected at random.
Step-by-step explanation:
Higher values pull averages up where medians just select the middle value and aren't necessarily pulled by outliers.
Non response biases happen when the individuals chosen choose not to answer or can volunteer to answer.
Sending out emails to everyone at the org is not choosing them at random.
A statistical advantage of using the median instead of the mean as the estimate of the typical amount raised is that the median is less sensitive to extreme values or outliers.
Method 1 would be the better choice for estimating the average yearly amount raised by all 10,530 members of the charity organization
What is a median?It is the middle value of the given set of numbers after arranging the given set of numbers in order.
We have,
Part A:
A statistical advantage of using the median instead of the mean as the estimate of the typical amount raised is that the median is less sensitive to extreme values or outliers.
In this case,
If there were a few attendees who contributed a very large amount of money, it would increase the mean and make it an overestimate of the typical amount raised.
However, the median would not be affected by the outliers, and it would give a better estimate of the typical amount raised by the majority of the attendees.
Part B:
Method 1 would be a better choice for estimating the average yearly amount raised by all 10,530 members of the charity organization.
This is because it would have a larger sample size than method 2, which would make the estimate more precise and reduce the sampling error.
Additionally,
Method 1 would include a broader range of members, including those who may not have attended the event or who may have contributed in other ways besides donating money.
Method 2, on the other hand, would have a smaller sample size and would only include a random subset of the organization's members, which could lead to sampling bias if the selected members are not representative of the larger population.
Furthermore, the follow-up required by method 2 would make it more time-consuming and potentially less cost-effective than method 1.
Thus,
Method 1 would be the better choice for estimating the average yearly amount raised by all 10,530 members of the charity organization because it would have a larger sample size, include a broader range of members, and be more cost-effective than method 2.

2. There were 1500 people at a high school football game. Student
tickets were $2.00 and adult tickets were $3.50. The total receipts for the
game were $3825. How many students bought tickets?
Let a = the number of adult tickets purchased.
Let s = the number of student tickets purchased.
a. Write a system of equations tha) can be used to determine the
number of adult and student tickets purchased.
b. Determine the number of adults tickets sold and the number of
student tickets sold. Use mathematics to explain how you
determined your answer.
Answer:
a = 950
s = 550
Step-by-step explanation:
Let a = the number of adult tickets purchased.
Let s = the number of student tickets purchased.
Therefore,
[tex]a + s = 1500 \implies \: s = 1500 - a...(1) \\ 2a + 3.5s = 3825...(2) \\ plugging \: s = 1500 - a \: in \: equation \: (2) \\ 2a + 3.5(1500 - a) = 3825 \\ 2a + 5250 - 3.5a = 3825 \\ 5250 - 1.5a = 3825 \\ 5250 - 3825 = 1.5a \\ 1425 = 1.5a \\ a = \frac{1425}{1.5} \\ \huge \red{ \boxed{ a = 950}} \\\implies s = 1500 - 950 \\ \huge \purple{ \boxed{s = 550}}[/tex]
So,
Number of adult tickets sold = 950
Number of students tickets sold = 550
a right cone has a surface area of 628 cm squared and a diameter of 10cm what is the slant length
Answer:
slant length = 35 cm
Step-by-step explanation:
A right cone has the vertex directly above the center of the base . The surface area of the right cone can be represented below.
surface area = πr(r + l)
where
r = radius
l = slant height/length
surface area = πr(r + l)
r = 10/2 = 5 cm
surface area = 628 cm²
Therefore,
628 = π × 5(5 + l)
628 = 5π(5 + l)
628 = 25π + 5πl
628 = 25 × 3.14 + 5 × 3.14 × l
628 = 78.5 + 15.7l
628 - 78.5 = 15.7l
549.5 = 15.7l
divide both sides by 15.7
l = 549.5/15.7
l = 35 cm
slant length = 35 cm
Answer:
35cm

Charlie has a box that is In the shape of a rectangular prism its height is twice the length its length is three times the width in the word measures 4 inches what is the volume of the box the volume of the box is
Answer:
1152 in ^ 3
Step-by-step explanation:
We know that the width is:
w = 4 in
They also tell us that the length is three times the width, therefore:
l = 3 * w
l = 3 * 4 = 12
l = 12 in
and as for the height, they tell us that it is twice the length, so:
h = 2 * l
h = 2 * 12 = 24
h = 24 in
now the volume is w * l * h, replacing:
v = 4 * 12 * 24
v = 1152
volume equals 1152 in ^ 3
