If you would like to solve (- 0.5) / (- 0.5) and - 50 / (- 0.5), you can do this using the following few steps:
(- 0.5) / (- 0.5) = 0.5 / 0.5 = 1
- 50 / (- 0.5<span>) = 50 / 0.5 = 50 / (5/10) = 50 / (1/2) = 50 * 2/1 = 100
</span>
The correct results would be: (- 0.5) / (- 0.5) = 1 and - 50 / (- 0.5<span>) = 100.</span>
First, you have to set a system of equations to determine the number of fiction and of nonfiction books.Call f the number of fiction books and n the number of nonfiction books. Then 400 = f + n. And f = n + 40 => n = f - 40 => 400 = f + f - 40 => 400 - 40 = 2f => f = 360 / 2 = 180. Now to find the probability of picking two fiction books, take into account the the Audrey will pick from 180 fiction books out of 400, and Ryan will pick from 179 fiction books out of 399, so the probability will be<span> (180/ 400) * (179/399) = 0.20 (rounded to two decimals). Answer: 0.20</span>
First subtract the two numbers:
8 - 5 = 3
Now divide this to the original:
3 / 5 = 0.6
Multiply by 100:
0.6 * 100 = 60%
Answer:
D.
90 x 1/2 = 45 km
The rate is 90 miles per hour and 30/60=1/2 so we multiply 1/2
Hope this helps
Step-by-step explanation:
Answer:
Riley did better than Darby because One-half < Three-fifths.
Step-by-step explanation:
The statement that explains which girl did better would be that
Riley did better than Darby because One-half < Three-fifths.
There are a total of 60 minutes in an hour, If we multiply each of these fractions by 60 minutes it would give us the exact number of minutes that each girl took to finish the race.
Riley: 
* 60 = 30 minutes
Darby: 
* 60 = 36 minutes
Therefore, we can see that it took Riley 6 minutes less than Darby to finish the race meaning that she had the better result.
