A typical work week is 40 hours. If you worked a minimum wage job in 1990, how many weeks did you have to work in order to pay for college? In 2017?
Answers
Step-by-step explanation:
For example, in the U.S in the late 19th century it was estimated that the average work week was over 60 hours per week. Today the average hours worked in the U.S. is around 33, with the average man employed full-time for 8.4 hours per work day, and the average woman employed full-time for 7.9 hours per work day.
Step-by-step explanation:
We will be using the trigonometric ratios of complementary angles to solve the given question.
sin (90° - θ) = cos θ
tan (90° - θ) = cot θ
sec (90° - θ) = cosec θ
(i) sin 18°/cos 72°
Since, sin (90° - θ) = cos θ
Here, θ = 72°
sin 18°/cos 72° = sin (90° - 72°)/cos 72°
= cos 72° / cos 72°
= 1
(ii) tan 26°/cot 64°
tan (90° - θ) = cot θ
Here, θ = 64°
tan 26°/cot 64° = tan (90° - 64°) / cot 64°
= cot 64°/cot 64°
= 1
(iii) cos 48° - sin 42°
Since, sin (90° - θ) = cos θ
Here, θ = 48°
cos 48° - sin 42° = cos 48° - sin (90° - 48°)
= cos 48° - cos 48°
= 0
(iv) cosec 31° - sec 59°
sec (90° - θ) = cosec θ
Here, θ = 31°
cosec 31° - sec 59° = cosec 31° - sec (90° - 31°)
= cosec 31° - cosec 31°
= 0
