Answer: The answer is 190°.
Step-by-step explanation: We are to find the measure of ∠T which lies between 0° and 360° and is co-terminal with an angle of measure -170°.
We know that two angles are said to be co-terminal if one is obtained from the other by either adding or subtracting 360°.
So, angles which are co-terminal with -170° are
-170° + 360° = 190°, -170° - 360° = 530°, etc.
Since 190° lies between 0° and 360°, so measure of ∠T is 190°.
Thus, the answer is 190°.
Since we know what time Dennis' sister finished babysitting, we can calculate how much money she's made since 9p.m. Between 9 and 11 is 2 hours, so we know she made $16 ($8 per hour x 2 hours).
That means she made $22 before 9p.m. ($32 total - $16 made past 9p.m.)
So, you just need to figure out how many hours $22 is worth and subtract that number of hours from 9p.m. That will get you to the starting point of babysitting.
$22 / $5.50 = 4 so we know that $22 is 4 hours' worth of babysitting.
9p.m. - 4 hours is 5p.m., so we know that Dennis' sister started babysitting at 5p.m.

Answer:
0.67 Laps per minute
Step-by-step explanation:
4 Laps over 6 Minutes
4/6 = 0.67
Solve the equation in the bracket first.
(q+q+3-6)=(2q-3)
so,
q=63-(2q-3)
expand it out,
q=63-2q+3
q=66-2q
then bring over the -2q to get +2q
q+2q=66
3q=66
then simplify
q=22
Answer:
Let X be the number of weeks.
2x - 16 = 14
we add 16 on both sides.
2x = 30
now we divide 2 on both sides to get rid of the 2 to the x, we want to get x on its own.
X = 15
