Answer:

Part = \frac{19}{20}

Lessons = 23

Step-by-step explanation:

Given:

Dancing\ Lessons = 24

April = \frac{3}{4}

May = \frac{1}{5}

Required:

Determine the part she took

To solve this, we simply add up the part she took in April and May.

Part = \frac{3}{4} + \frac{1}{5}

Take LCM

Part = \frac{15 + 4}{20}

Part = \frac{19}{20}

Hence, she took \frac{19}{20} of the dancing lesson.

However, to calculate the number of lesson.

We have to multiply \frac{19}{20} by the total dancing lessons.

Lessons = \frac{19}{20} * 24

Lessons = \frac{19* 24}{20}

Lessons = \frac{456}{20}

Lessons = 22.8

Lessons = 23 ---- Approximated

Answer:

5.5

Step-by-step explanation:

2,3,3,4,5,7,8,8,8,10,10,12

The mean of this data is 7.5.  So what you are trying to figure out is the mean between 2 and 7.  Since that is 3 and 4 it would be 3.5.  So 3.5 is the Q1.  Now you have to figure out the mean between 8 and 12.  That is 9.  This is Q3.  You have to subtract 9-3.5 and that is the interquartile range. So 5.5 is the answer.  I hope that made sense.

1. The formula for the volume of a cone is
Andre45 [30]

Answer:

r=\sqrt{\frac{3V}{\pi\ h}}

Step-by-step explanation:

The volume of cone is given by:

V=\frac{1}{3}\pi\ r^2\ h

where r is the radius of the base and h is the height of the cone.

We need to solve for r

we have V=\frac{1}{3}\ \pi\ r^2\ h

Multiplying both sides by 3 to remove \frac{1}{3}

⇒ 3\times V=3\times \frac{1}{3}\ \pi\ r^2\ h

⇒ 3V=\pi\ r^2\ h

dividing both sides by \pi\ h

⇒ \frac{3V}{\pi\ h}=\frac{\pi r^2 h}{\pi\ h}

⇒ \frac{3V}{\pi\ h}=r^2

Taking square root both sides:

⇒ \sqrt{\frac{3V}{\pi\ h}}=\sqrt{r^2}

⇒ \sqrt{\frac{3V}{\pi\ h}}=r

∴ r=\sqrt{\frac{3V}{\pi\ h}}
