Answer:
x= 37/63
Step-by-step explanation:
= x+5/2x-12 =
base, and it stays, log becomes exponent)
32/1= x+5/2x-1 = cross multiply 32 x (2x-1)
64x-32=x+5 = simplify
63x=37
Answer:
Chlorine: -34 °C
Krypton: -153.2 °C
Step-by-step explanation:
Boiling point of elements in degree Celsius (°C)
Argon: -185.8 °C
Chlorine: -34 °C
Fluorine: -188.1 °C
Hydrogen: -252.87 °C
Krypton: -153.2 °C
Helium: -268.9 °C
Boiling points that are above the boiling point of Argon.
Chlorine: -34 °C
Krypton: -153.2 °C
Answer:
36 hotdogs
Step-by-step explanation: Let x= number of hot dogs sold to break even
Equation: 57+0.50x=12+1.75x
subtract 12 from both sides: 45+0.50x=1.75x
subtract 0.50x from both sides: 45=1.25x
Divide both sides by 1.25: x=36
The probability of a diamond is 13/52 = 1/4 So none of the diamonds can be used for the other 2 restrictions.
The even numbered cards are 2 4 8 10.
The 6 cannot be used, because it could come into the next category. Six is divisible by 3.
These can come from clubs hearts and spades.
So each even number has 3 suits it can come from
The number of cards in this category is 3 * 4 = 12
The probability of this occurring is 12/39 = 4/13
The cards divisible by 3 are
3 and 9 [Again you can't use the 6]
The Total number of cards are 2*3 = 6
The probability is 6/39 = 2/13
The total probability (without drawing a 6) is
1/4 + 2/13 + 4/13 = 37/52
The two categories where a 6 can turn up are equally likely so choosing the category is 1/2. the probability of a 6 turning up in the first category is 1/2* 3/39 = 3/78 = 1/26
The probability of the 6 turning up in the second category is 1/2 * 3/39 = 3/78 = 1/26 So these two numbers must added into the mix.
37/52 + 2(1/26) = 37/52 + 1/13 = 41/52
