Answer:
3/8
Step-by-step explanation:
Find the common factor, which is 24. To make the other fractions have a denominator of 24, multiply the denominator and numerator by a factor that will have the denominator get 24 (the multiplied number has to be the same for the top and bottom). 27/24 divided by 3 is 27/24.You will get 1/4=6/24, and 5/6=20/24. 6/24 + 20/24 = 26/24 + 1/24= 27/24. Divide by 3 since there are 3 numbers. Once you are done dividing, you will get 27/72, and 3/8 is the simplified answer.
Answer:
4.99
Step-by-step explanation:
- nearest whole: 5
- nearest tenth: 5.0
- to round to the nearest hundredth, you need three or more numbers on the right side of the decimal point. with this number you can't round to the nearest hundredth.
Answer:
θ = 60° or θ = 120°, which in radians is equivalent to θ = π/3 rad or θ = 2π/3 rad.
Explanation:
The given equation is sin θ = (√3)/2
Solving that equation is finding the value of the angle, θ, whose sine is (√3)/2.
The function that returns the value of the angle whose sine is (√3)/2 is the inverse function of the sine and it has a special name: arc sine or arcsin.
Hence, θ = arcsin (√3)/2.
You can use your knowledge of the notable angles to solve for that equation.
1) The function sine is positive in first and second quadrants.
2) The angles in the first quadrant go from 0° to 90°.
3) The sine of 60° (√3)/2, Hence the first value of θ is 60°
4) The angles in the second quatrant go from 90° to 120°. 60° is the reference angle in the second quadrant, and the angle searched is
- 180° - reference angle = 180° - 60° = 120°. So, 120° is the other solution of the equation.
5) You can convert both angles to radians using the equivalence
- π radians = 180° ⇒ 1 = π rad / 180°
- 60° = 60° × π rad / 180° = π/ 3 rad
- 120° = 120° × π rad / 180° = 2π/3 rad
6) You can verify that sin 60° = (√3)/2 = sin 120° .
