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
2x-5y=16 =>10x-25y=80
5x+3y=9 => 10x+6y=18
subtract one from the other: (6-(-25)y=(18-80), 31y=-62, y=-2
plug y=-2 in 2x-5y=16 to find x: 2x+10=16, x=3
12x+y=12*3-2=34
no, they have different variables
Answer:
a1
Step-by-step explanation:
Just add the numerators if both fractions to get: a + 1 = a1
Answer:
240 inches cubed
Step-by-step explanation:
Volume = L x W x H
Take 8 x 10x 3 = 240
dont forget to put inches cubed (in.^3)
