Answer:
Step-by-step explanation:
Train 1 will travel for 2 hours before the second train leaves.
<u>The distance at 2 o'clock is reduced by 2*90 = 180 miles and now is:</u>
<u>Let the trains spend x hours before crossing, then we have following equation for the distance:</u>
- x(90 + 80) = 1820
- 170x = 1820
- x = 1820/170
- x = 10 120/170 = 10 12/17 hours ≈ 10 hours and 42 minutes
<u>The trains will cross at:</u>
- 2 o'clock + 10 h 42 min = 12:42
The time when trains cross each other will be approximately 12:42

Answer:
116.6 pounds
Step-by-step explanation:
Set up a proportion where x is the weight of her desk in pounds:
=
Cross multiply:
x = 116.6
So, her desk is 116.6 pounds
Answer:
Not correct
Step-by-step explanation:
Sample 8 has one free throw, sample 9 has 3 free throw success,
sample 10 has 3 free throw success
sample 11 has 5 free throw success
sample 12 has 5 free throw success
sample 13 has 2 free throw success
sample 14 has 1 free throw success;
See one sample should contain 15 free throw and the probability of success should be 0.7
Let's look at sample 8
Total no of success is 1
Total no of free throws 15
Probability is 1/15 = 1/15 * 100 =6.67%
Similarly you can do so for the others.
