28×4/15-4/15=7.2
（40+1.2×40）×3=264
3.5×（1.5-0.5）+0.5×1.5=4.25

What's 13 out of 20 minus 3 out of 10

7 out of 20

What is 287 divided by 13 minus 101 divided by 13 minus 82 divided by 13

280÷13-101÷13-82÷13
=(287-101-82)÷13
=104÷13
=8

As shown in the figure, if ∠ 1 = 65 ° 15 ′, ∠ 2 = 78 ° 30 ′, then ∠ 3 is______ Degree

The answer is 36 ° 15 ′

Given AOB = 65 degrees and 15 minutes, AOC = 78 degrees and 30 minutes, calculate the degree of BOC

Angle BOC = 180 degrees - 65 degrees 15 minutes - 78 degrees 30 minutes = 46 degrees 55 minutes

How to translate 6 ° =? Rad?

6°=(6÷180)πrad=π/30

Radian conversion: 1 degree=______ rad,1rad=______ Degree

π / 180 degrees / π

Rad and angle conversion

1 rad is about 57 degrees

How much is 50 μ rad converted into "°"

50μrad= 50*10^-6rad
1rad=180/π °
50μrad= （50*10^-6rad）*180/π
= 0.002864°

How to convert rad / sec to RPM?

Revolutions = 2 * 3.1415 rad
1 Rad/sec = 60*1/(2*3.1415) Rev/min = 9.55 RPM
