A) 130 mins = 2 hours 10 mins or 2 and 1/6 hours... so 2 and 1/6 revolution. and 1 revolution is equal to 2*pi radians
<span>ANSWER: 13/6 (2 and 1/6) * 2*pi = 13.6 radians </span>
<span>b) 8/13.6 = x/(13/6) so x = 0.2715 hours or 16 and 1/3 minutes </span>
<span>c) if the restaurant is 21 meters, the radius is 10.5 meters, and the circumference is 2*pi*r so circumference = 65.97 meters. </span>
<span>2 and 1/6 revolution is going around the circumference 2 and 1/6 times, so simply multiply 65.97 by 13/6 </span>
<span>ANSWER: about 143 meters</span>
Answer:
A, 12.5
Putting them in order was this:
10, 11, 11, 11, 12, 13, 13, 15, 15, 17
and the median is between 12 and 13, which is 12.5
(Hope that helps you. ^^)
4.
b^-2-x^-2/b^-1+x^-1
b^-2/b^-1=b^-1
x^-2/x^-1=x^-1
As a result, the simplest form is:
b^-1-x^-1. Hope it help!
Answer:
t(12)=40 t(24)=-3.2
Step-by-step explanation:
t(12)=40 because, if you replace 12 with t in the equation, everything but 40 cancels out.
t(24)=-3.2 because, if you plug in 24 for t it will be the same as the first equation where t is 0.
