It has been 1 hour and 20 minutes.
HOW I FOUND MY ANSWER:
7:10 to 8:10 = 1 hour
8:10 to 8:30 = 20 minutes
(1 hour + 20 minutes = 1 hr and 20 min.)
HOPE THIS HELPED

Answer:
<h3>
x=60</h3>
Step-by-step explanation:
5=k×
k=180
3=180×
x=60
Let's assign a variable that is the number when multiplied by 10% it is equal to 0.1.
Well let that be x.
Now we want to convert the 10% into a decimal. To convert a percent into a decimal, simply move the % sign two places to the left and make it into a decimal point.
When we say "of" in mathematics what we really mean is to multiply.
0.10 * x = 0.1
That is the equation we need to find the value of x for.
Divide both sides by 0.10
0.10 * x = 0.1
The 0.10 on the left side cancels out.
x = 1
So, the answer to this question is if we multiply 10% by 1 we will get 0.1.
When you add 2pi to the angle, the amount is still the same. Therefore, you can make -17pi/4 positive by adding 6pi to it.
6pi + (-17pi/4)
= 24pi/4 - 17pi/4
= 7pi/4
