Answer:
Between the 10- and 20- second marks
Step-by-step explanation:
in the first half of filling the container it started at 0- 10 and the points goes further to 30 which is 10 plus 20 equals to 30, which is between the 10- and 20- second marks.

Answer: -pi/4 and 3pi/4
Step-by-step explanation:
Whenever you're given an inverse trig function like this, think "tangent of what gives me -1?" There are multiple ways in which you can solve this; knowing how tangent work, guess checking sin/cos to get -1, or using a calculator. The only way tangent can be an integer is if the sine and cosine of the angle are equal.
The only spots on the pi circle where this happens is pi/4, 3pi/4, 5pi/4, and 7pi/4. Answers B and D are correct
Karl: k hours
Ryan: r hours
r+k=14 hrs
r = 2k-1 hrs
Then (2k-1) + k = 14 hours; 3k -1 = 14 hours; 3k = 15 hours; k = 5 hours.
Karl worked 5 hours; Ryan worked 2(5 hours) -1 hour = 9 hours.
Answer:
<em>The correct option is: 32.4 km/h</em>
Step-by-step explanation:
The fastest recorded speed of a turtle while swimming is 9 m/s.
Now, 9 m/s 
1 kilometer= 1000 meter
So, 1 meter
kilometer
and <u>9 meters</u>
kilometer
Now, 1 hour = 3600 seconds
So, <u>1 second</u> 
Thus, we will get.........

So, the speed of the turtle will be 32.4 km/h.
