Answer: it will take the faster computer 15 minutes to do the job on its own.
Step-by-step explanation:
Let t represent the number of minutes it will take the faster computer to do the job on its own. It means that the rate at which it does the job per minute is 1/t
If it takes the slower computer 30 minutes to do the job on its own. It means that the rate at which it does the job on its own per minute is 1/30
By working together, they would work simultaneously and their individual rates are additive. Working together it takes two computers 10 minutes to send out a company's email. It means that the rate at which both computers work together per minute is 1/10 Therefore,
1/t + 1/30 = 1/10
Cross multiplying by 30x, it becomes
3x = x + 30
3x - x = 30
2x = 30
x = 30/2
x = 15 minutes
Answer:
y=2x-7
Step-by-step explanation:
m==2
y=mx+b
9=16-7
y=2x-7
You do the square root of 75
and then with that number you divide it by 5
and that is your answer
Answer:
1/6 and 16.67
Step-by-step explanation:
Add all the marbles, you get 12.
There's 2 out of 12 yellow marbles so you get 2/12
2/12 simplified to 1/6
So 1/6 is the probability as a fraction
Now to get the percentage just divide 100 by 6.
100/6 equals 16.67
Since it's 1/6 we multiply that by one
16.67 times 1 equals 16.67
Answer: ab+a-b
ab+ac-a2
