Answer: 2ft 8in
Step-by-step explanation:
Convert to inches - 6ft 8in ----> 6 x 12 + 8 = 80
Divide - 80/2 = 40
Subtract - 40 - 6 = 32
We have two things here
Michaels share is x
Ethans share is y
6x=4y
And x+y=80
The equation on the top when divided by 2 equals 3x=2y
x=2y/3
So we have:
x+y=80
2y/3 + y =80 /*3
2y +3y= 240
5 y = 240
y= 48
x+y=80
x+48= 80
x= 80-48
x=32
You've got halfway through it! All you have to now is set the two equations equal to each other and solve for x.
2500+0.03x=1500+0.035x
1000+0.03x=0.035x
1000=0.005x
200000=x
$200,000
Good luck!
The problem here is: Too many words.
If you boil the problem down to the bare facts, the question is:
"$210 is 15% of what number ?"
I'm pretty sure you can take it from there,
but here's the rest of it anyway:
$210 = 15% of (March amount)
$210 = 0.15 x (March amount)
Divide each side by 0.15 : $1400 = March amount .
Check:
1400 + 210 = 1610
1.15 x 1400 = 1610 yay!
The probability that Hamid guesses both answers correctly is 10%.
Since Hamid is playing a trivia game with multiple choice questions, and each question has 2 correct answers among 5 answer choices, and Hamid has no idea what the answers to a certain question are, so he needs to choose two different answers at random, to determine what is the probability that Hamid guesses both answers correctly the following calculation must be performed:
- 2/5 x 1/4 = X
- 0.4 x 0.25 = X
- 0.1 = X
- 0.1 x 100 = 10
Therefore, the probability that Hamid guesses both answers correctly is 10%.
