Question writer: it's customary to keep the degree sign off of the variable names in trig.
sin y = s/8
tan y = s/t
tan y = sin y / cos y
cos y = sin y / tan y
cos y = (s/8) / (s/t) = (s/8) × (t/s) = t/8
Answer: cos y = t/8, third choice
Answer:
The window should be positioned 4 1/8 feet far from each edge of the wall.
Step-by-step explanation:
Since a construction crew is placing a square in a wall for a new window, which is 3 1/8 feet wide, while the wall has a length of 11 3/8 feet, and the crew wants to position the window at the center of the wall, to determine how far from each edge of the wall should the window be positioned, the following calculation must be performed:
1/8 = 0.125
3/8 = 0.375
(11,375 - 3,125) / 2 = X
8.25 / 2 = X
4.125 = X
Therefore, the window should be positioned 4 1/8 feet far from each edge of the wall.
If i remember correctly 500*3.2%=16 and 16*4 equals $64.
