Answer:
Step-by-step explanation:
A number doubled is the same as squaring it (to the second power).
Have a great day!
Option A. The angles do not have the same reference angle.
Explanation:
1) <u>Angle 5π / 3 radians:</u>
- Convert radians to degrees: 5π/3 × 180° / π = 300°
- 300° is in the fourth quadrant
- The reference angle for angles in the fourth quadrant is 360° - angle ⇒ 360° - 300° = 60°.
- ∴ The reference angle for this angle is 60°.
2) <u>Angle 5π / 6 radians:</u>
- Convert radians to degrees: 5π/6 × 180° / π = 150°
- 150° is in the second quadrant
- The reference angle for angles in the second quadrant is 180° - angle ⇒ 180° - 150° = 30°.
- ∴ The reference angle for this angle is 30°.
3) <u>Conclusion</u>:
- Since the reference angles are different, the tangent ratios have different values.
- tan (5π/3) = - tan(60°) = - √3
- tan (5π/6) = - tan(30°) = - (√3)/3
Note that the tangent is negative in both second and fourth quadrants.
Hi there!
In order to answer your question, you'll need to use the cross product method:
<u>(100 × 270)</u> ÷ 1,800 = X
<u>27,000 ÷ 1,800</u> = X
15 = X
= 15%
Your answer is: Isaac put 15% of his earnings into his savings.
There you go! I really hope this helped, if there's anything just let me know! :)
You have to round to the nearest whole number so it would be 500 and 70
so the equation would be 500+70<span />
Answer:
The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5
Step-by-step explanation:
Let
x ------> the number of pounds of apples
(x-2) -----> the number of pounds of grapes
we know that
Solve for x
so
therefore
The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5
