Answer:
1/4
Step-by-step explanation:
There are 54 cards in a deck including jokers, so if you count how many face cards there are and jokers and subtract them from 54 you get 40, then you divide 40 by 2 to get 20/40 since it is even numbered and half of the time you would get an even number. then you divide the die by 2 to get 1/2 and multiply them to get your answer 1/4.
Oops some miscalculations.

120? I believe sorry if you get it wrong!
Answer:
7√3
Step-by-step explanation:
To simplify a square root, look for some of its factors. You are especially looking for factors that are square numbers, or sometimes factors that repeat (repeating factors give you a square number).
√147
=√3·49 Remember 49 is a square number, you can take out its square root.
=7√3 Simplified.
You might also end up with these factors instead.
√147
=√3·7·7 Two same factors mean a square number you can take out.
=7√3 Simplified form.
Answer:
x = 60
y = 200
Step-by-step explanations:
Selling price:
Price of program = $0.5
Price of music = $5
Cost of production :
Program = $0.15 per program
CD = $1.75 per CD
Total Revenue = $400
Total Profit = $265
Let
Number of CD's = x
Number of program's = y
(0.5y + 5x) = 400
0.5y = 400 - 5x
y = (400 - 5x) / 0.5
y = 800 - 10x (1(
Cost of production:
1.75x + 0.15y
Profit = Total Revenue - Total cost of production
5x + 0.5y - 1.75x + 0.15y = 265
3.25x + 0.35y = 265 (2)
Put y = 800 - 10x in (2)
3.25x + 0.35y = 265
3.25x + 0.35(800 - 10x) = 265
3.25x + 280 - 3.5x = 265
-0.25x = - 15
Divide both sides by -0.25
x = -15/ -0.25
x = 60
y = 800 - 10x
= 800 - 10(60)
= 800 - 600
= 200
y = 200
