8*8=64 well 2*2=4 hope it helps
If they meet after 8 hours, then the sum of their average speeds is 600/8=75 km per hour. If one is 5 km per hour faster than the other, then if we set the speed of the slower man to x, we have:
2x+5=75
So:
2x=70
x=30
The fastest man is 5 km per hour faster than the slower, so he travels 35 km per hour.
Answer: 3 ⅞, 3¾, 3⅔, 3 2/5
Step-by-step explanation:
The order of the pencils lengths from greatest to lowest will be converted to percentage to make it easier.
3 7/8 = 3.875
3 2/5 = 3.4
3 3/4 = 3.75
3 2/3 = 3.67
Therefore, from greatest to lowest will be:
3 ⅞, 3¾, 3⅔, 3 2/5
Let the number of hours Brian travelled = X
Then the number of hours Anne traveled = 5X + 2
Since they together travelled 20 hours, then
X + ( 5X + 2) = 20
X + 5X + 2 = 20
6X + 2 = 20
6X = 20 - 2
6X = 18
X = 18/6
= 3 hours.
So brian travels for a period of 3 hours.
Now the number of hours Anne travelled = 5X +2
= (5 * 3) + 2
= 15 + 2
= 17 hours.
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>
