A group of college DJs surveyed students to find out what music to plan for their upcoming parties. Thirty percent of the studen

Aneli [31]

Answer:

Thus, option “c” 10% is correct.

Step-by-step explanation:

The percentage of students that like dubstep = 30%

The percentage of students that like trance music = 25%

The percentage of student that wants only house music = 20%

The percentage of students that like bot dubstep and trance = 15%

Now we have to find the percentage of students that like trance music but nor dubstep.

The percentage of students that like the trance music but nor dubstep = 100% - 30% – 25 % - 20% - 15%

The percentage of students that like trance music but nor dubstep = 10%

Thus, option “c” 10% is correct.

Let V be the volume of a right circular cone of height h=14 whose base is a circle of radius R=2. An illustration a right circul

Alla [95]

Answer:

The area of a horizontal cross section at a height is $\pi\times(2-\dfrac{y}{7})^2$

Step-by-step explanation:

Given that,

Height = 14 m

Radius = 2 m

Let V be the volume of a right circular cone

We need to calculate the value of R

Using given data

$\dfrac{h}{r}=\dfrac{h-y}{R}$

Put the value into the formula

$\dfrac{14}{2}=\dfrac{14-y}{R}$

$7R=14-y$

$R=2-\dfrac{y}{7}$

We need to calculate the area of a horizontal cross section at a height y

Using formula of area

$A=\pi R^2$

Put the value into the formula

$A=\pi\times(2-\dfrac{y}{7})^2$

Hence, The area of a horizontal cross section at a height is $\pi\times(2-\dfrac{y}{7})^2$
