Amy earns $0.16 per unit for the work she does. For all units she produces in a week over 1,000, she receives $0.26. What were her weekly earnings if she produced 1,725 units in one week?
Answer: The number of units produced by Amy in one week 
For the first 1000 units, she earns $0.16 per unit. Therefore, her total earning's for the first 1000 units is $0.16 x 1000 = $160
For the remaining 1725 - 1000 = 725 units, she earns $0.26. Therefore, her total earning for the 725 units is $0.26 x 725 = $188.5
Therefore, Amy's total for one week = $160 + $188.5 = $348.5
Hence, the option b. $348.50 is correct
False. Although, I'm not 100% sure.
Answer:
The scientist can calculate the distance between the moon and the sun using trigonometric ratio of Cosine.
Step-by-step explanation:
We have been given that the moon forms a right triangle with the Earth and the Sun during one of its phases.
We can see from our graph that the distance between Sun and Moon is the hypotenuse of the right triangle as it is the opposite side of right angle formed with the Earth.
The distance between Earth and Sun (y) is the adjacent side for our angle x degrees.
Since we know that the cosine of an angle is the trigonometric ratio of the adjacent side to the hypotenuse of a right triangle containing that angle.



Therefore, using trigonometric ratio Cosine, the scientist can calculate the distance between the Moon and the Sun.
If it's a regular polygon, find the angle measures. If it equals 90degrees then they're perpendicular
