the width of the vegetable garden is 1/3 times its length. if the length of the garden is 7 3/4, what is the width in simplest f

Valentin [98]

w = width

l = length

w = 1/3 length

l = 7 3/4

w = 1/3 * length

w = 1/3 ( 7 3/4)

change the mixed number to an improper fraction

7 3/4 = (4*7+3)/4 = 31/4

w = 1/3 ( 31/4) = 31/12

12 goes in to 31 2 times with 7 left over

w = 2 7 /12

A cyclist is riding a bicycle whose wheels have a diameter of feet. Suppose the wheels turn at a rate of revolutions per minute.

SCORPION-xisa [38]

Answer:

a.2010 rad/min

b.2412 feet/min

Step-by-step explanation:

We are given that

Diameter of wheel,d=2.4 feet

Radius,r= $\frac{d}{2}=\frac{2.4}{2}=1.2feet$

a.Rate=320 rev/minute

1 rev= $2\pi$ radian

320 rev/minute= $320\times 2\pi=640\pi radian/minute$

Where $\pi=3.14$

Angular speed= $640\times 3.14=2010 rad/min$

b.Speed,v= $r\omega$

$v=2010\times 1.2=2412 feet/min$
