Answer:
13
Step-by-step explanation:
 6 - 2(-1) + | -5 |
The absolute value means take the non-negative value
 6 - 2(-1) + 5
Multiply
6 +2 + 5
Add
8+5

Answer:
B
Step-by-step explanation:
this is because 8*10= 80 and 80*6=480 so your <u><em>answer is 480</em></u>
 
        
             
        
        
        
We can find the height of the altitude by the ratio of sin. See my attachment.
sin of angle = side in front of the angle / hypotenuse
sin x = height/distance
If the two pilot is rising in an hour, then the first distance is 400 miles, the second distance is 300 miles.
Find the height of first pilotheight/distance = sin x 
height/400 = sin 30°
height = sin 30° × 400
height = 1/2 × 400
height = 200
Find the height of second pilotheight/distance = sin x 
height/300 = sin 40°
height = sin 40° × 300
height = 0.642 × 300
height = 192
So the first pilot traveling 400 mph with 30° is more quickly to reach high altitude than the second pilot traveling 300 mph with 40°
