Answer:

Step-by-step explanation:

Area of a rectangle is given as length times breadth. Mathematically,

A = l * b

If the length is halved and the breadth is constant, then we have

A = l/2 * b

A = lb/2

From the above, the area of a rectangle is lb, while the area of the hypothetical rectangle will be lb/2

This means that, if the length is halved, and the width is constant, then the area of the rectangle reduces by half.

Step-by-step explanation:

Let $p$ and $q$ be two <em>propositional statements</em>.

The disjunction $p\vee q$ is true if either $p$ or $q$ is true or both are true.

In the given options;

The statement;

$7-4=11$ is false

But;

$6+3=9$ is true.

Hence,

Alik [6]

Step-by-step explanation:

Let the number of singing act be x

Let the number of comedy act be y

If the total act is 14, then;

x+y = 14..... 1

If singing acts are 4.5 minutes long and comedy acts are 3.5 minutes long and the acts lasts 59 minutes, then:

4.5x + 3.5y = 59 .......... 2

Solve both equation simultaneously for x and y

x+y = 14

45x+35y = 590

.................................

x+y = 14......... *9

9x+7y = 118....... 1

...............................

9x+9y = 126

9x+7y = 118

Subtract both equations

9y-7y = 126-118

2y = 8

y = 8/2

y = 4

Substitute y = 4 into equation 1;

From 1: x+y = 14

x+4 = 14

x = 14-4

x =10

Hence there are 10 singing acts and 4 comedy acts in the show
