Answers:
- pi/3 radians = 60 degrees
- pi/4 radians = 45 degrees
- pi/2 radians = 90 degrees
=======================================
Explanation:
To apply the conversion, we use the idea that pi radians is equivalent to 180 degrees
pi radians = 180 degrees
To convert from radians to degrees, we'll multiply by the conversion factor (180/pi)
This leads us to the following:
- (pi/3 radians)*(180/pi) = (pi*180)/(3*pi) = 180/3 = 60. So pi/3 radians converts to 60 degrees
- (pi/4 radians)*(180/pi) = (pi*180)/(4*pi) = 180/4 = 45. So pi/4 radians converts to 45 degrees
- (pi/2 radians)*(180/pi) = (pi*180)/(2*pi) = 180/2 = 90. So pi/2 radians converts to 90 degrees
You have to add the first year then for the 2nd year you have to add the estimated difference
Avg. speed Joanna runs: 7.5km/h
how much she runs everyday: 15km
15km/7.5= 2 hours of running time everyday
She leaves at 8:30, comes back at ?
8:30+ 2:00= 10:30
Joanna arrives back at 10:30a.m.
Answer:
The result of the division of a number by a fraction is larger than the fraction.
Step-by-step explanation:
Here,we note that value Parker divided by 0.6. =1.02
Written down result of the division = 1.02/0.6 = 0.17
However, since the numerator is 1.02, then the result of dividing it by a fraction should yield a higher number instead of 0.17
Therefore we check as follows
1.02/0.6 = 1.7
The error is apparently due to dividing 1.02 by 6 rather than 0.6
