Answer: 90° angle

Step-by-step explanation: In the image provided, you can see that the 2 lines cross at a point so they're intersecting lines. However, notice the box that is used at the point where the lines meet. This box means that the lines meet at a 90° angle or a right angle and 2 lines that intersect at a right angle are called perpendicular lines which means that the lines are perpendicular.

On one day, 4 chefs and 5 helpers earned $650.
Arlecino [84]
4c + 5h = 650 and

5c + 6h = 800 where c are chefs, h are helpers

Start by finding an expression for c

4c + 5h = 650
4c = 650 -5h
c = (650- 5h)/4

Then substitute that into the second equation and solve for a number value for h
5 (650-5h)/4 + 6h = 800
(3250-25h)/4 + 6h = 800
Multiply both sides by 4
3250-25h + 24h = 3200
-h = -50
h = 50

Take that 50 and substitute it into the expression we have for c to get a number value for c

C= 650-5(50)/4
C = 650-250/4
C = 400/4
C= 100

Check your first equations, substituting $50 for the helpers and $100 for the chefs.

4 (100) + 5(50) =
400 + 250 = 650

5(100) + 6(50) =
500 + 300 = 800

Consider a deck of cards:
Ganezh [65]

Ohhhh nasty !  What a delightful little problem !

The first card can be any one of the 52 in the deck.  For each one ...
The second card can be any one of the 39 in the other 3 suits. For each one ...
The third card can be any one of the 26 in the other 2 suits.  For each one ...
The fourth card can be any one of the 13 in the last suit.

Total possible ways to draw them = (52 x 39 x 26 x 13) = 685,464 ways.

But wait !  That's not the answer yet.

Once you have the 4 cards in your hand, you can arrange them
in (4 x 3 x 2 x 1) = 24 different arrangements.  That tells you that
the same hand could have been drawn in 24 different ways.  So
the number of different 4-card hands is only ...

                     (685,464) / (24) = <em>28,561 hands</em>.

I love it !
