Answers

Answer: D

Step-by-step explanation:

Segment MP is a diameter of circle O.


Circle O is shown. Line segment M P is a diameter. Line segment N O is a radius. Angle N O P is 150 degrees.


Which equation can be used to find mArc M N?

mArc M N – 150 = 360

Answers

Answer:

[tex]arc\ MN + 150 = 180[/tex]

Step-by-step explanation:

Given

[tex]\angle NOP = 150^\circ[/tex]

See attachment for circle O

Required

Find [tex]arc\ MN[/tex]

The sum of angles in a semi-circle is 180 degrees.

So:

[tex]arc\ MN + \angle NOP = 180[/tex]

This gives:

[tex]arc\ MN + 150 = 180[/tex]

Hence, the equation is: [tex]arc\ MN + 150 = 180[/tex]

Answer:

4 8.95h + 10 < 115

Step-by-step explanation:

Answer: 4) 8.95h + 10 < 115

Step-by-step explanation:

We know the inequality will be equal to less than 115 since it states that the order was less than $115.

The equation would look like: some amount of shin guards times 8.95 each + $10 shipping = less than $115

8.95h + 10 < 115

(h in the given equation is the amount of shin guards)

Simplify the expression.

A person whose eyes are 5 feet above the ground is standing on the runway of an airport 100 feet from the control tower. That person spots one of the air traffic controller at the window of the 132 foot tall tower. What is the angle of elevation to the nearest tenth of a degree?

Answers

Answer:

132-5 therefore the height from the eyes to the window is 127

100 feet away from the base of the tower  

This forms two legs of a triangle

trying to find the degrees of this triangle.

Since its the two legs, you can use tanx which = to opposite side/adjacent side

Therefore, it is tanx = 127/100

But you are looking for x so arctan(1.27)

Must use calculator to find x.
