Answer:
a
Step-by-step explanation:
Answer:
12 minutes
Option D
Step-by-step explanation:
Given that circuar gears P and Q start rotating at the same time at constant speeds.
Gear P makes 10 revolutions per minute and Gear Q makes 40 revolutions per minute.
Both gears start at the same time.
No of rotations per minute are 10 and 40
Difference is 30 in one minute
For 6 difference we must have exactly 1/5 minutes
which equals 12 seconds.
In 1/5 minutes or 12 seconds gear P would have completed 2 revolutions while Gear Q would have completed 8 revolutions thus making difference as 6.
Slope Intercept Form Equation: mx + b = y
Use the slope, like 3/2 or 4, but first plot the y-intercept, like 3, and then put the equation to these: y = 3/2x + 4 or y = 4x + 4. Plot the y-intercept on the y- axis (the vertical line). If you were to use my examples, you would plot the y-intercept by (0,4). Then if you used my first example equation, move 2 to the right of the plotted coordinates and then up by 3. If you were to use my second equation, however, then you would move to the left of the same plotted coordinates, (0,4), 1 to the right and then up 4.
Answer:
j=1.571
Step-by-step explanation:
to get j by itself you have to divide 7 by 11
so,
11/7=j
j=1.571
