Looking for some furniture for her new apartment, Susan visits the local swap meet in search of something cheap. Knowing that most swap meet vendors willnot accept credit cards and that she will not have any money until her next payday, Susan decides to take out a $200 cash advance on her credit card at an interest rate of 32%. If Susan had no previous balance on her credit card, and she manages to pay off the balance within 1 month, how much will she have to pay in interest?

Answers

Given:
cash advance = 200
interest rate = 32% , I'm assuming this is a per annum rate.
pay w/in a month.

I = 200 * 32% * 1/12
I = 5.33

She will have to pay 5.33 in interest after 1 month.

what is the length of the diagonal of a non-regulation tennis court with length 20 feet and width 15 feet?

Answers

Answer:

25 feet

Step-by-step explanation:

Basically that non-regulation tennis court is a rectangle. You want to know the length of the diagonal. If you draw it on paper, you'll see that this then become 2 triangles... of which you have 2 sides, and are seeking the hypotenuse. So....

H² = A² + B²

H² = 20² + 15² = 400 + 225 = 625

H = 25 feet.

Answer:

The diagonal of a non-regulation tennis court = 25 feet

Step-by-step explanation:

Pythagorean theorem

Hypotenuse² = Base² + Height²

The tennis court is like a rectangle.

We can consider the court as made of two right angled triangle

To find the length of diagonal of court

Here base = 15 feet and height = 20 feet

Diagonal or hypotenuse can be written as,

Diagonal ² = Base² + Height²

= 15² + 20²

= 225 + 400

= 625

Diagonal = √625 = 25 feet

Therefore the diagonal of a non-regulation tennis court = 25 feet

A bus and a car leave from the same city traveling in opposite directions. The bus leaves 2 hours before the car does. The bus travels at a steady speed of 50 mph while the car travels at 70 mph. After how many hours will the bus and car be 800 miles apart?

Answers

Normally, I would pass right by this question, because it is so complicated
and there are so many numbers in it. But I've allowed myself to become
seduced by the bounty of a full 5 points waiting at the end of the rainbow,
and I decided to rush in where more reasonable people would rightly fear
to tread.

The answer is a number, that represents "after how many hours". So we
need to know how many hours AFTER WHAT. The question is not very
clear on when the beginning of time is, so I need to decide. I'm going to
say that the time when the bus leaves is the beginning of time. And I'm
going to call ' H ' the number of hours AFTER the bus leaves.

-- The bus covers 50 miles every hour. So 'H' hours after the bus leaves,
the bus is 50H miles away from the city, in some direction.

-- The car leaves 2 hours later. So 'H' hours after the bus leaves, the car
has only been traveling for (H-2) hours.

-- The car covers 70 miles every hour. So 'H' hours after the bus leaves,
the car is (70)x(H-2) miles away from the city, in the OTHER direction.

-- Since the bus and the car are moving in opposite directions, the distance
between the bus and the car is the SUM of the distances each one covers.

   'H' hours after the bus leaves, they are (50H) plus (70)(H-2) miles apart.

What we need to figure out is: When is that distance 800 miles ?

The distance between them at 'H' hours after the bus leaves is

                                              (50H) plus (70)(H-2) miles

Eliminate the first parentheses:         50H + (70)(H-2)

Eliminate the rest of the parentheses:   50H + 70H - 140

Combine the terms with 'H' in them:         120H - 140

So here's the equation:                            120H - 140 = 800

Add 140 to each side:                            120H      = 940

Divide each side by 120 :                             H = 7.8333 hours
                                                                           = 7 and 5/6 hours
   = 7 hours and 50 minutes
   after the bus leaves.

Check:

Assume that H = 7 hrs 50 minutes (7 and 5/6 hours)
The bus has covered (50 x 7-5/6) = 391 and 2/3 miles.

The car has been traveling for only 5 and 5/6 hours
The car has covered   (70) x (5-5/6) = 408 and 1/3 miles

How far apart are they ?   (391-2/3) + (408-1/3) = 800 miles !       YAY!

Note: If the book or the homework sheet wants to count the hours
after the CAR leaves, then the answer is 5-5/6 hours, not 7-5/6 .
