Tan = sin/cos
(3/5)/(4/5)=(3/5)*(5/4)=3/4
Answer:
(24r-10)/2
Step-by-step explanation:
12r-5 Lets multiply everything by 2 since we are given nothing to simplify
24r-10 now we have to make it equivalent to 12r-5
So all we will do is put it in a fraction bar
24r-10 is the numerator and 2 is the denominator
So the final result is: (24r-10)/2
0.5 repeating as a fraction is 5/9
0.5 as a fraction is 1/2
its 5/9 because it is closer to the next number since it is repeating.
the numbers in the decimals either end up as the numerator or the denominator
In this question, there are 4 consolation door and 2 car doors of total 6 doors. That means for the first door the chance to get consolation is 4/6 and car is 2/6. In second door, only 5 remains so the chance to get consolation is either 4/5 (if 1st door car) or 3/5(if 1st door consolation)
Win 1 car condition:
1. 1st door car, 2nd door consolation = 2/6 * 4/5 =8/30
2. 1st door consolation, 2nd door car= 4/6 * 2/5 = 8/30
8/30+8/30= 16/30
No car condition
1. 1st door consolation, 2nd door consolation= 4/6 * 3/5= 12/30
At least one car condition
1. 1st door car, 2nd door car = 2/6 * 1/5 =2/30
2. 1st door car, 2nd door consolation = 2/6 * 4/5 =8/30
3. 1st door consolation, 2nd door car= 4/6 * 2/5 = 8/30
2/30 + 8/30 + 8/30= 18/30
Omg why do we have to have 20 letters
true is the answer
