Answer 1

Answer:

Because 20% of $10 will not be the same as 20% of a larger number

Step-by-step explanation:

120% of 10= 1.2(10)=$12

So we added $2 on the mark up.

Marking 20% off of $12 means the price will be 80% of 12= .8(12)= $9.60

This was a reduction of $2.40 which is 20% of $12

Answer 2

Answer:

Step-by-step explanation:

20% of 10 is $2

Marked up: 10+2 = $12

Marked down: 20% of 12 is 2.40 = 12-2.40 = $ 9.60

20% of 10 is not the same as 20% of 12.

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.

Answers

Answer:

19.26 miles

Step-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 deg

Find x:

x/2.5 = cot (17.52°) ⇒ x = 2.5*3.1677 ≈ 7.92 mi

Find y:

y/25 = cot (12.43°) ⇒ y = 2.5*4.5369 ≈ 11.34 mi

The distance between the planes:

7.92 + 11.34 = 19.26 mi

Credit Card         Balance       APR

     #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.

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.

I gave the answers to questions 5 and 7 because I wanted to give you the opportunity to try out the working outs yourself for a better understanding on your part and see if you can get the same answers as me. Anyway hope this helped.
