Jack’s bicycle tires have a diameter of 24 inches. If he rides at 15 miles per hour, what is the angular velocity of the wheels
Oksanka [162]

Answer:

Option 3 ⇒ 210.08 rpm

Step-by-step explanation:

The relation between the angular velocity ω and the linear velocity v is v=ωr

Where r is the radius of the tire.

Given that a diameter of 24 inches. If he rides at 15 miles per hour.

∴ r = diameter/2 = 24/2 = 12 in.

And v = 15 miles/hour

Converting the speed to inches per minutes where mile = 63,360 inches and hour = 60 minuted

∴ v = 15 * 63,360/60 = 15,840 inches/minute

∴ ω = v/r = 15,840/12 = 1,320 rad/minute

Converting ω from rad per minutes to revolutions per minute

Where 1 revolution = 2π

∴ ω = 1,320 / (2π) = 210.08 rpm

Eureka Math : 5 ÷ 1/3= ____. There are ___ thirds in 1 whole. There are ___ thirds in 5 wholes. If 5 is 1/3, what is the whole?
oksian1 [2.3K]

Let me edit your question to simplify it.

Eureka Math :

A)5 ÷ 1/3= ____.

B) There are ___ thirds in 1 whole.

C) There are ___ thirds in 5 wholes.

D) If 5 of 1/3, what is the whole? ___

E) 3 ÷1/5= ____ .

F) There are ___ fifths in 1 whole.

G) There are ___ fifths in 3 wholes.

H) If 3 of 1/5, what is the whole?___

Answer:

A) 15

B) three thirds

C) 15 wholes

D) whole is 2

E) 15

F) five fifths

G) 15 fifths

H) whole is 1

Step-by-step explanation:

A)

  • 5÷\frac{1}{3} =5*\frac{3}{1}
  • 5÷\frac{1}{3}=15

<u>Third:</u>

  • third means \frac{1}{3}<u> </u>

B)

  • To make 1 whole from thirds, we need three thirds i.e. \frac{1}{3}+\frac{1}{3}+\frac{1}{3}=\frac{3}{3}=1\ Whole

C)

  • In 1 whole there are three thirds, so in 5 wholes there are 5*3=15 wholes.

D)

  • In 5\ of\ \frac{1}{3}=5*\frac{1}{3} =\frac{5}{3}
  • \frac{5}{3}=1.6
  • The whole of 1.6 or \frac{5}{3} is 2 (rounding 1.6 to 2)

E)

  • 3÷\frac{1}{5}=3*5=15

<u>Fifth:</u> means \frac{1}{5}

F)

  • To make 1 whole of fifths we need five fifths i.e. \frac{1}{5} +\frac{1}{5} +\frac{1}{5} +\frac{1}{5} +\frac{1}{5}=\frac{1+1+1+1+1}{5}=\frac{5}{5}=1

G)

  • In 1 whole we have 5 fifths, so in 3 wholes we have 3*5=15 fifths

H)

  • 3\ of\ \frac{1}{5}=3*\frac{1}{5}=\frac{3}{5}=0.6
  • rounding 0.6 equals to 1
  • thus whole is 1.
