We are interested in the dimensions of a certain square. A rectangle has a length of 5 units more than the side of the square an

JulijaS [17]

Lets consider the side of square be 'x' units
So as per data,
Length of rectangle is x+5
Breadth of rectangle is x/2

and also as per data, the areas of rectangle and square are equal.
Area of rectangle = Length * Breadth = (x+5)*x/2 = $( x^{2} +5x)/2$ <- equation1
Area of square = Side* Side= x*x = $x^{2}$ <- equation2

As per given data, Equation1 and equation 2 are equal
so
$( x^{2} +5x)/2$ = tex] x^{2} [/tex]
$x^{2} +5x = 2 x^{2}$
$2 x^{2} - x^{2} = 5x$
$x^{2} = 5x$
x = 5

So the side of square = 5 units

For Square, both dimensions are equal.

A group orders 3 large veggie pizzas. Each slice represents 1/8 of the entire pizza. The group eats 3/4 of the pizza. How many s

anyanavicka [17]

The first step is to calculate the total number of pizza slices there are.

We know each slice is 1/8 of the pizza. (think of 1/8 as 1 out of 8 pieces)
This means each pizza has 8 slices.
There are 3 pizzas so there are 8 x 3 = 24 slices total

Next we want to figure how many slices of pizza they ate which will help us figure out how many are left.

They ate 3/4 of the pizza, so in other words only 1/4 of the pizza is left.

In order to figure out how many slices are left, all we need to do is find out what 1/4 of the total number of slices are.

# of slices left = Total number of slices x 1/4 (1/4 of the pizza is left)

# of slices left = 24 x 1/4 = 24÷4 = 6

This means there are 6 slices of pizza left.

The population of retired citizens in Memphis is 54000. If the population decreases at a rate of 5.9 % each year. What will the

kobusy [5.1K]

We will have the following:

First, we construct the exponential decay function, that is:

$P(x)=54000(1-0.059)^x\Rightarrow P(x)=54000(0.941)^x$

Now, we will determine the population after 6 years:

$P(6)=54000(0.941)^6\Rightarrow P(6)=37491.38638$

So, the population after 6 years will be of approximately 37491 people-
