Town A starts with 2in and has a rate of accumulation of 6in every 1 hour
Town B starts with 9in and has a rate of accumulation of 3in every 1 hour
If X is number of hours then:
2+ 6X= 9+3X
6x-3x=9-2
3x=7
X=7/3 is about 2 hours
Answer: B; 2≤x≤8
Step-by-step explanation:
Do left part first: 0≤3x-6, 2≤x
Now do right part: 3x-6≤18, x≤8
Now combine into double inequality: 2≤x≤8
for this case we have to define trigonometric relations of rectangular triangles, that the tangent of an angle is given by the leg opposite the angle on the leg adjacent to the angle. So:
Answer:
11x10 is 121 rounded to the nearest tenth is 120
Step-by-step explanation:
Midpoint = 1/2(6+9,8+7)
= 1/2(15,15) = (15/2,15/2)
