A motorcycle tire with a radius of 16 inches rotates at a rate of 150 revolutions per minute (rpm).
a) Find the linear speed of the tire in inches per minute.
b) Find the angular speed of the tire in radians per minute.

Answers

Answer: (a)942.85 rad/s

(b) 15,085.71 inches per minute

Step-by-step explanation:

Given

the radius of tire r=16 inches

N=150 revolution per minute(rpm)

So, the angular speed of the tire  [tex]\omega=2\pi N=2\times \frac{22}{7}\times 150=942.85\ rad/minute[/tex]

The linear speed of the tire [tex]v=\omega r[/tex]

[tex]v=\dfrac{6600}{7}\times 16=15,085.71\ \text{inches per minute}[/tex]

A 30 foot ladder is leaned against a wall, and the base of the ladder is 2 feet from the
base of the wall. What is the angle of inclination of the ladder? (Round to the nearest
whole degree)

Answers

answer: 86°
explanation:
we can assume the ground makes a 90° angle with the wall. We can use primary trig ratios to determine the angle of inclination, which is between the ladder and the ground.
The hypotenuse is the length of the ladder, 30ft, and the adjacent side of our theta angle, (the angle we’re looking for) is 2ft.
Use the ratio Cosine and set up the equation
cosx = 2/30
cosx = 0.066667
x = 86°

Answers

Answer:

y = 5

Step-by-step explanation:

The triangle is an isosceles triangle, which means that it has two equal sides and two equal angles.

Therefore, angles B and C are both equal to 75°.

A triangle measures 180°.

75 + 75 + x = 180

150 + x = 180

x = 30°

Angle A has to equal 30°.

(4y + 10)° = 30

4y + 10 - 10 = 30 - 10

4y = 20

y = 5

Hope that helps.
