B is the answer bc it the only one that makes sense
4/12 equals 2/6 which is smaller than 4/6 so the correct answer is 4/12 <4/6
Answer:
i think it is y = -4/5x + 4
Step-by-step explanation:
4x + 5y = 20
Subtract 4x on both sides
5y = -4x + 20
Divide 5 on both sides
y = -4/5x + 4
Answer:
1) Correct
2) Wrong
3) Operate Within Parentheses
4) 60°
Step-by-step explanation:
The original equation is correct because 180 - (60 + 60) = 180 - 120.
180 - 120 = 60
If Puzzled Penguin operated within the parentheses first he would have arrived at the correct answer.
Hope this helped.
Taking the observation point as a vertex. The line to the observed window is the hypotenuse of a right triangle formed with the horizontal distance between the two buildings and the opposite leg to the angle of elevation.
The tangent of this angle is the ratio between the opposite leg and the adjacent leg. And the opposite leg is also the height from the height of the observation window to the observed window.
If h is the height from ground level to the second window, we will call h - 40 to the opposite leg and d to the adjacent leg that is also the horizontal distance between the buildings.
tangent(43º) = 0,93251509 = (h - 40)/d
h = tangent(43º)*d + 40 feet = 0,93251509*110 feet + 40 feet = 142.58 feet
Answer = C.) = 140 feet above the ground level is the second window.
