Based on the calculations, the true statements are:

A. The angular velocity is 10π rad/sec.

E. The angular velocity is 600π rad/min.

<h3>How to calculate the angular velocity?</h3>

Mathematically, angular velocity can be calculated by using this formula:

ω = θ/t

<u>Where:</u>

  • ω is the angular velocity.
  • θ is the angle.
  • t is the time.

<u>Note:</u> 1/2 revolution = 0.5 × 2π = π radians.

Substituting the given parameters into the formula, we have;

ω = θ/t

ω = π/0.1

ω = 10π rad/s.

Next, we would convert the time in seconds to minutes:

ω = 10π × 60

ω = 600π rad/min.

A souvenir shop sells two sizes of American flags. Small flags cost $3.50 and large flags cost $6.50. On a recent day, 155 flags
Mariulka [41]

Answer:

Small flags = 108

large flags= 47

Step-by-step explanation:

Step one:

given

let the number of small lag be x

and big flags be y

so

3.5x+6.5y= 683.5----------1

x+y=155------------------------2

Step two:

from eqn 2 x= 155-y

put x= 155-y in  eqn 1

3.5(155-y)+6.5y= 683.5

542.5-3.5y+6.5y=683.5

collect like terms

3y=141

divide by 3

y= 141/3

y=47

Step three:

put y= 47 in eqn 2

x+47=155

x= 155-47

x=108

What is the measure of arc bc
aleksklad [387]

Answer:

100 deg

Step-by-step explanation:

As the property of inscribed angle on circle, angle BEC = (1/2)(arc BC)

=> arc BC = 2 x angle BEC = 2 x 50 = 100 deg
