soldier1979 [14.2K]

Answer:

\frac{9}{20} students.

Step-by-step explanation:

We have been given that of the students that attended Roosevelt Elementary 6/8 of the school play a sport. Of the students are playing a sport 3/5 of the students are also involved in the drama club.

To find the students are both play a sport and a part of the drama club, we need to find 3/5 part of 6/8 as:

\text{Students who play a sport and a part of the drama club}=\frac{6}{8}\times \frac{3}{5}

\text{Students who play a sport and a part of the drama club}=\frac{3}{4}\times \frac{3}{5}

\text{Students who play a sport and a part of the drama club}=\frac{3\times 3}{4\times 5}

\text{Students who play a sport and a part of the drama club}=\frac{9}{20}

Therefore, \frac{9}{20} students play sport and part of the drama club.

U=F(r+B) solve for r
irina1246 [14]
<h2>The value of r = \dfrac{U-FB}{F}</h2>

Step-by-step explanation:

We have,

U = F(r + B)

To find, the value of r = ?

∴ U = F(r + B)

Dividing both sides by F, we get

\dfrac{U }{F}=\dfrac{F(r+B) }{F}

⇒ \dfrac{U }{F} = r + B

⇒ r + B = \dfrac{U }{F}

⇒ r =  \dfrac{U }{F} - B

⇒ r = \dfrac{U-FB}{F}

∴ The value of r =\dfrac{U-FB}{F}

two comets orbit the Sun. One comet travels 30,000 miles per hour and the other comet travels 28,500 miles per hour. What is the
GenaCL600 [577]

The difference of the distances traveled by the comets for any given number of minutes is 25t.

Since the first comet travels at a speed of 30,000 miles per hour, the distance it travels in t minutes is d = 30000 mph × 1 h/60 min × t = 500t miles.

Also, the second comet travels at a speed of 28,500 miles per hour, the distance it travels in t minutes is d' = 28,500 mph × 1 h/60 min × t = 475t miles.

So, the difference in the distances traveled by the comets D = d - d'

= 500t - 475t

= 25t

So, the difference of the distances traveled by the comets for any given number of minutes is 25t.
