Reference angle of -3 radians is α= - 171° 53 min 15 sec .
We know the formula for calculating circular arc
Let l=circular arc which ic according to central angle of the circle α
l=((2R π)/360)α Let l=1 radian and R=1 (unit circle with radius R=1)
1= ((2π)/360)α => α= 360/(2π)= 180/π= 57° 17 min 45sec
Angle of the 1 radian is equal to angle 57° 17min 45sec
According to this
angle of the -3 radians = -3 ( 57° 17min 45sec) = - 171° 53min 15sec
when you count in the clockwise direction.
Good luck!!!
Answer:
1=28 students 2=14students 3=40%
Step-by-step explanation:
<u>1.</u> 70 students = 100%
7 students = 10%
28 students = 40%
28 students are sixth graders!
<u>2.</u>70 students = 100%
7 students = 10%
14 students = 20%
14 students are seventh graders!
<u>3</u>.Percentage of band that is eighth graders: 40+20=60% 100%-60%=40%
40% are eighth graders!
Y= x-3 2y-2x=-6
1) add the 2x to both sides// 2y=2x-6
2) divide the 2 on both sides// y=x-3
Answer:
90.2
Step-by-step explanation:
Assuming that you can use a calculator, you would need to type in the square root symbol and type in the value 8136.04.
The square root of 8136.04 is 90.2.
Answer:
7:10:34
Step-by-step explanation:
1. Ratio outline:
Length 1:Length 2:Perimeter
2. Length 1 = 35 feet
3. Length 2 = 50 feet
4. Perimeter = Length of all sides
- Since, a ractangle has 4 sides and the opposite sides are equal, we do Perimeter = 35+50+35+50 = 170
5. Substitute the values into the ratio outline:
35:50:170
6. Convert into simplest form: Divide by greatest common factor (5)
7:10:34
