<span>4 hours after they leave Houston.
Easiest way to solve this problem is to first calculate the relative velocities of the two buses. Since they're traveling in opposite directions, you simply need to add their respective velocities to see what the relative velocity is between them.
55 mi/h + 45 mi/h = 100 mi/h
That means that the buses will increase their distance apart from each other by 100 miles for every hour that they travel. So divide 400 miles by 100 miles/hour
400 miles / 100 miles/hour = 4 hours.
So 4 hours after the buses start moving, they will be 400 miles apart from each other.</span>

Answer:
5.33 trays must be sold to cover all costs including labor...
Step-by-step explanation:
We have given:
Party trays, which cost $14.00 to make not including labor, are sold for $35.00.
Profit on party trays excluding labour cost = $35 - $14 = $21
Now we will find total labor cost for making party tray for a day
Total labor hours * wages per hour* No. of labors
= $7 * $8*2
= $112
Therefore to find how many trays must be sold to cover all costs including labor just divide total labour cost for making party tray for a day by profit on party trays excluding labour cost.
= $112/$21
= 5.33
It means 5.33 trays must be sold to cover all costs including labor...
To answer this question, we will use the sine law which is illustrated in the attached image.
We are given that:The distance from school to library = a
∠A = 32
∠B = 110
b = 2.2
Substitute with the givens in the relation of the sine law to get a as follows:(sin 32) / (a) = (sin 110) / (2.2)
a = (2.2 sin 32) / (sin 110)
distance from school to library = a = 1.2406 mi
Based on the above calculations, the best choice would be:B. 1.2 mi
the amount of times the die is rolled is equal to 100%
if 2 was to be rolled 4 out of 6 times that would mean it would be 80%
the answer is D.
