Work=speed times time (my equation to help me figure it out)
ok, 10 men take 84 days to complete a job
therefor, each man completes 1/10 of the job in 84 days
each man does 1/840 of the job per 1 day
so, if we had 5 more, or 15 men
15 times 1/840 times xdays=1 job complete
15/840 times xdays=1job
times both sides by 840/15
xdays=840/15
xdays=56
56 days it would take
<span>The <u>correct answer</u> is:
$31.40.
Explanation<span>:
Since 6 oranges cost $3.00, we can divide to find the cost of one orange:
3.00/6 = $0.50. Each orange costs $0.50.
If ten oranges are bought, this would cost 10(0.50)=$5.00.
Each grapefruit costs $2.40; 11 of them would cost 11(2.40) = 26.40.
Together the total cost is $5+$26.40 = $31.40.</span></span>
Answer:
1. Rolling a number less than 5
The numbers on a standard dice are 1, 2, 3, 4, 5, and 6. Therefore it is possible to roll a 6, but it is much more likely to be 1-5, simply because there are more of them.
2. Rolling a 2
Again, it is more likely that the result will be one of the other 5 numbers. But obviously a 2 is still an option, so it's not impossible.
3. Rolling a number less than 10
Every option is less than 10 so it is certain.
Answer:
69, -69
Step-by-step explanation:
If the number is positive, the opposite of it is the same number, but negative.
If the number is negative, the opposite of the number is the same number, but positive.
So, -69 would be 69.
69 is the opposite of -69, so the opposite of 69 would go back to -69.
