Since lines a and b are parallel, we can assume that y,u,x, and s are equal and z, r, and t equal 158. We know that angles t and s are supplementary angles, so we can find angle s by subtracting 158 from 180. 180-158=22. Angle s is equal to 22.
Answer:
B. 0 ≤ x ≤ 6
Step-by-step explanation:
The horizontal grid lines are 10 °C apart, so 45 °C corresponds to a vertical position halfway between the 4th grid line and the one marked 50.
The graph intersects that position at the 2nd vertical grid line. The vertical grid lines are 3 minutes apart, so the 2nd grid line represents 6 minutes.
If Peter conducted the experiment from its start until the temperature reached 45 °C, he conducted it over a period of 0 to 6 minutes, inclusive:
0 ≤ x ≤ 6
The second machine would print 750 books in 30 hours that week.
