Answer:
0.3 hour or 18 minutes
Step-by-step explanation:
How long means, we are to calculate the time(t)
Hence,
Speed × time = Distance
For Neil , 11 × t
For Charlie = 9 × t
11t + 9t = 6
20t = 6
t = 6/20
t = 0.3 hour
Converting to minutes
1 hour = 60 minutes
0.3 hour = x
x = 0.3 × 60 minutes
x = 18 minutes
Therefore, it will take 0.3 hour or 18 minutes for these two to meet.

Step-by-step explanation:
Answer:
65.46 units
Step-by-step explanation:
Given the information:
- The vertex angle of an isosceles triangle measures 26°
=> the leg angle is:
= (180° - 26° )/2
= 77°
Let x is the length of the leg side (x>0)
We use cosine law to find x, we have:
= 
Because the isosceles has two equal leg sides
<=> = 2
- 1.79
<=> 0.21 =
<=> 
<=> x = 65.46 units
Hope it will find you well.
Answer:
the answer is 17 or -11
Step-by-step explanation:
|x-3| - 4 = 10
|x-3| = 14
x-3 = 14 or -14
x = 17 or -11
