Flights 204 and 317 are both approaching Hartsfield Atlanta International Airport from directions directly opposite one another and at an altitude of 2.5 miles. The pilot on flight 204 reports an angle of depression of 17 degrees 47 minutes to the tower, and the pilot on flight 317 reports an angle of depression of 12 degrees 39 minutes to the tower. Calculate the distance between the planes.
Answer:
19.26 milesStep-by-step explanation:
Refer to attached picture. Not to scale.
The picture explains all the given parameters.
We need to find the distance d, which is the sum of x and y.
First convert minutes to degrees:
47 min = 47/90 deg = 0.52 deg39 min = 39/90 deg = 0.43 degFind x:
x/2.5 = cot (17.52°) ⇒ x = 2.5*3.1677 ≈ 7.92 miFind y:
y/25 = cot (12.43°) ⇒ y = 2.5*4.5369 ≈ 11.34 miThe distance between the planes:
7.92 + 11.34 = 19.26 miplease help this is due today
Answer:
Q4) 256 roses
Q5) 40 hamburgers
Q6) 60 professors and 168 lecturers
Q7) 20 percussionist on the sideline
Step-by-step explanation:
Q4) First to set up a proportion you simply have to write a letter to represent the missing number. In this case we'll be using x. So it'll look something like these:
I) 160:5 = x:8 (using colon) or
II) 160/5 = x/8 (as two equal fractions)
You can use one of the two above.
I used the fractions here to solve the question.
After setting up the proportion, your going to cross multiply to get the value of x so its going to look like this:
160×8 = 5×x
1280 = 5x
5x = 1280
Now you have to divide on both sides to isolate x.
5x÷5 = 1280÷5
x = 256
Therefore your answer is 256 roses.
Q5) Use the same method in Q4.
Q6) This is where the proportion using colon comes in. It should look like this 5:14. 5 representing the professors and 14 the lecturers. Now it said that the total number of faculty members is 228.
First thing your going to do is add the proportion together. So basically 5+14=19.
After acquiring this your going to use the sum to divide the total number of faculty members which is 228. So 228÷19=12.
And finally you now have to multiply both sides of the proportion by 12. Therefore 5×12:14×12
60:168
To make sure the answer is right add the proportions of the working above which will give you the total number of faculty members. 60+168=228.
Your final answer: There are 60 professors and 168 lecturers.
Q7) Use the same method done in Q6.

Alice earns $185 for working 14.8 hours each week. How much money will Alice earn if she increased her hours to 18 1/2 hours per week?
:)
Step-by-step explanation:
185 is to 14.8 as x is to 18.5
185/14.8 = x/18.5
x = 185(18.5)/14.8
x = $231.25
Michelle has four credit cards with the balances and interest rates listed below. Rather than budget to pay each of the credit cards off in 36 months, Michelle would like to pay them off one at a time based on the balance for each credit card. In which order should Michelle pay off her credit cards?
Credit Card
Balance
APR
#1
$4,380
17%
#2
$1,365
19%
#3
$2,480
23%
#4

b.
4,1,3,2
c.
4,3,1,2
d.
1,3,2,4
Answer:
B) 4,1,3,2
Explanation:
Michele's credit cards have the following balances and APR
Credit Card Balance APR
#1 $4,380 17%
#2 $1,365 19%
#3 $2,480 23%
#4 $5,000 15%
If she wants to start paying them off one at a time depending on their balance, she could start by paying the credit card with the highest balance, then continue with the second highest balance and so on. She would pay first her credit card #4, then #1, #3 and finally #2.

addison and kelsey are running on a path modeled by x^2+y^2-10x-18y-378=0, where the distance is in meters. what is the maximum distance between the runners at any given time
The maximum distance is the diameter of the circle, which is of 44 units.
The equation of a circle of radius r and center [tex](x_0,y_0)[/tex] is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
The diameter is twice the radius, and is the maximum distance between two points inside a circle.In this problem, the circular path is modeled by:
[tex]x^2 + y^2 - 10x - 18y - 378 = 0[/tex]
We complete the squares to place it in the standard format, thus:
[tex]x^2 - 10x + y^2 - 18y = 378[/tex]
[tex](x - 5)^2 + (y - 9)^2 = 378 + 25 + 81[/tex]
[tex](x - 5)^2 + (y - 9)^2 = 484[/tex]
Thus, the radius is:
[tex]r^2 = 484 \rightarrow r = \sqrt{484} = 22[/tex]
Then, the diameter is:
[tex]d = 2r = 2(22) = 44[/tex]
The maximum distance is the diameter of the circle, which is of 44 units.

-7(w+4) +2w - 15 simplify
Answer:
w=-8.6 is your answer
-5w-43. is the simple version
Step-by-step explanation:
First distrubute the -7 and set equal to 0 so that we can move the w to the other side.
-7w-28+2w-15=0
-5w-43=0
add 43 to both sides so you can slove for w
-5w=43
divide both sides by -5 to isolate the w
w=-8.6
A=D+qm, solve for q.........
Step-by-step explanation:
A=D+qm
qm = A - D
q =(A-D) /m
Answer:
q = (A - D)/m
Step-by-step explanation:
A = D + qm
A - D = qm
(A - D)/m = q
So, the solve for q is q = (A - D)/m
