A square has four equal sides a, so the perimeter is 4a.

The side of the square is 5 ft long.

The length is increased by 2 ft -> 5+2=7 ft.

The width is decreased by 1 ft -> 5-1=4 ft.

The new figure is a rectangle with the dimensions 4 ft x 7 ft.

The area of a rectangle is the product of the length and the width.

The area of the new figure is 28 ft².

The side of the square is 5 ft long.

The length is increased by 2 ft -> 5+2=7 ft.

The width is decreased by 1 ft -> 5-1=4 ft.

The new figure is a rectangle with the dimensions 4 ft x 7 ft.

The area of a rectangle is the product of the length and the width.

The area of the new figure is 28 ft².

$32.072 ≈ $32.07

20% of $38 is equal to $7.60

$38 - $7.60 = $30.40

5.5% of $30.40 = 1.672

$30.40 + $1.672 = $32.072

20% of $38 is equal to $7.60

$38 - $7.60 = $30.40

5.5% of $30.40 = 1.672

$30.40 + $1.672 = $32.072

Given problem : You increased form 5 dollars to 8 dollars. Find the percentage increase of this given number.
=> Original number = 5 dollars
=> Increased number = 8 Dollars.
First, let’s find how much did it increased
=> 8 – 5 = 3 – thus it increased 3 dollars which is more than 50%
Let’s start solving to get the percentage.
=> 3 / 5 = 0.6 * 100 = 60%
Thus, it increased for 60%. Lets check if we have the correct answer.
=> 5 * .6 = 3.

Yolanda had 47 customers on Saturday from 6 to 7 pm. Then on Monday she only had 20 customers from 5pm to 6pm.
Question: Let’s find how much percentage rate did Yolanda’s customer’s decreased over time.
Solution
=> Saturday = 47 customers.
=> Monday = 20 customer.
Let’s start solcing
=> 47 – 20 = 27
There are 27 customer that were lost over time.
=> 27 / 47 = 0.57 * 100 = 57%
Let’s try checking our answer:
=> 47 * .57 = 26.79 or round off to 27, since we rounded off also our percentage.

Use trigonometry to get the side of the square. The diagonal of a square creates two right triangles. These right triangles are consistent - meaning their angles have 90, 45 and 45 degrees.

Getting the length of the side can either be used a cosine or sine function, that is

cos 45 = (3 radical 2)/x

x = (3 radical 2)/cos 45

x = 6

The perimeter of the square is 4*sides. Therefore,

**P = 4*6 = 24 cm**

Getting the length of the side can either be used a cosine or sine function, that is

A.

Let

5x = number of games won

2x = number of games lost

The total number of win and lose is 154. So

5x + 2x = 154

Solving for x,

7x = 154

x = 22

Therefore, the number of games won is 5*22=110 and the number of games lost is 2*22 is 44.

b.

Let

6x = first side of the triangle

7x = second side of the triangle

9x = third side of the triangle

The perimeter of a triangle is the total of all sides. So,

6x + 7x + 9x = 88

22x = 88

x = 4

Therefore, the three lengths of the side are 6*4=24, 7*4=28, and 9*4 = 36

Let

5x = number of games won

2x = number of games lost

The total number of win and lose is 154. So

5x + 2x = 154

x = 22

Therefore, the number of games won is 5*22=110 and the number of games lost is 2*22 is 44.

Let x for the altitude and y for the temperature.

Determine the value of slope:

m = (y - y1)/(x - x1)

Given two points (8200, 203.34) and (4700, 207.89),

m = (207.89 - 203.34)/(4700 - 8200) = -0.0013

Make a linear equation for this case.

y - y1 = m(x - x1)

y - 203.34 = -0.0013(x - 8200)

y - 203.34 = -0.0013x + 10.66

y = -0.0013x + 214

At x = 2100 ft

y = -0.0013(2100) + 214 = 211.27 F

To get a percent rate, let the value of the car based on two consecutive years. The variable x represents a year. You can set any two numbers of year as long as they are consecutive; say x = 0 and x = 1.

Use the calculator to get instantly the values of V(x).

For V(x = 0)

V(x = 0) = 107,000(1.009)^[2/3(0)] = 107,000

For V(x = 1)

V(x - 1) = 107,000(1.009)^[2/3(1)] = 107,641

Another way of getting the percentage between two values is called the "relative change."

(107,641 - 107,000) / 107,000 = 0.0060 = 0.60%
