Given positive integer num_insects, write a while loop that prints that number doubled up to, but without exceeding 100. Follow

nasty-shy [4]

Answer:

import java.util.Scanner;

public class CocaColaVendingTest {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter value for number of insects");

int num_insects = in.nextInt();

while (num_insects<=100){

System.out.print(num_insects);

num_insects*=2;

System.out.print(" ");

}

Explanation:

In the code above written in Java.

The user is prompted to enter a positive value for the number of insects

This is stored in a variable num_insects.

Using a while loop with the condition while (num_insects<=100). The num_insects is printed out. Then it is doubled followed with a space.

It continues until the condition in the while loop is no longer true

the volume of two similar solids are 1080cm and 1715cm .if the curved surface area of the smaller cone is 840cm .fond the curved

gavmur [86]

Answer:

$A_{big} = 1143.33cm^2$

Explanation:

The given parameters are:

$V_{small} = 1080$

$V_{big} = 1715$

$C_{small} = 840$

Required

Determine the curved surface area of the big cone

The volume of a cone is:

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

For the big cone:

$V_{big} = \frac{1}{3}\pi R^2H$

Where

R = radius of the big cone and H = height of the big cone

For the small cone:

$V_{small} = \frac{1}{3}\pi r^2h$

Where

r = radius of the small cone and H = height of the small cone

Because both cones are similar, then:

$\frac{H}{h} = \frac{R}{r}$

and

$\frac{V_{big}}{V_{small}} = \frac{\frac{1}{3}\pi R^2H}{\frac{1}{3}\pi r^2h}$

$\frac{V_{big}}{V_{small}} = \frac{R^2H}{r^2h}$

Substitute values for Vbig and Vsmall

$\frac{1715}{1080} = \frac{R^2H}{r^2h}$

Recall that: $\frac{H}{h} = \frac{R}{r}$

So, we have:

$\frac{1715}{1080} = \frac{R^2*R}{r^2*r}$

$\frac{1715}{1080} = \frac{R^3}{r^3}$

Take cube roots of both sides

$\sqrt[3]{\frac{1715}{1080}} = \frac{R}{r}$

Factorize

$\sqrt[3]{\frac{343*5}{216*5}} = \frac{R}{r}$

$\sqrt[3]{\frac{343}{216}} = \frac{R}{r}$

$\frac{7}{6} = \frac{R}{r}$

The curved surface area is calculated as:

$Area = \pi rl$

Where

$l = slant\ height$

For the big cone:

$A_{big} = \pi RL$

For the small cone

$A_{small} = \pi rl$

Because both cones are similar, then:

$\frac{L}{l} = \frac{R}{r}$

and

$\frac{A_{big}}{A_{small}} = \frac{\pi RL}{\pi rl}$

$\frac{A_{big}}{A_{small}} = \frac{RL}{rl}$

This gives:

$\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{L}{l}$

Recall that:

$\frac{L}{l} = \frac{R}{r}$

So, we have:

$\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{R}{r}$

$\frac{A_{big}}{A_{small}} = (\frac{R}{r})^2$

Make $A_{big}$ the subject

$A_{big} = (\frac{R}{r})^2 * A_{small}$

Substitute values for $\frac{R}{r}$ and $A_{small}$

$A_{big} = (\frac{7}{6})^2 * 840$

$A_{big} = \frac{49}{36} * 840$

$A_{big} = \frac{49* 840}{36}$

$A_{big} = 1143.33cm^2$

<em>Hence, the curved surface area of the big cone is 1143.33cm^2</em>

HELP FOR JAVASCRIPT: 01. What is prototypical inheritance? 02. How can JavaScript be used to improve accessibility on the web? I

Vlada [557]

Answer:

Following are the answer to this question:

Explanation:

Prototypical inheritance:

This inheritance is a part of the object-oriented programming, in the JavaScript, the prototype is also an instance of an entity, on this type of inheritance an object inherits another object directly, in which an instance could be composed of several sources which enable simple selective inheritance and a flat structure of delegation[[Prototype]].

Web accessibility using JavaScript:

In the website or web page, JavaScript is usually fully accessible if another script 's implementation has been device-independent, and the components are accessible to be used in assistive devices. It enables the developers to improve web page information, which helps in communication, data processing, and regulation, and it also helps in management.
