Answer:

65%

Step-by-step explanation:

survey of 2,700 people who owned a certain type of​ car, 1,755 said they would buy that type of car again. What percent of the people surveyed were satisfied with the​ car?

Total car number of car owner= 2,700

Then the percentage that satisfied is

1,755

1755/2700*100= 65%

Answer:

11/20 ; 0.55

Step-by-step explanation:

11= 20x

20x= 11

x= 11/20 ; 0.55

Answer:

x = −9

Step-by-step explanation:

Step 1: Simplify both sides of the equation

11 = x + 20

Step 2: Flip the equation

x + 20 = 11

Step 3: Subtract 20 from both sides

x + 20 − 20 = 11 − 20

x = −9

Answer:155 hours

Step-by-step explanation:

$75+$6h=$1,000

Subtract $75 on both sides:

$75-$75+$6h=$1,000

$6h=$925

Divide 6 on both sides:

6/6h=925/6

h=154.1666667

After I rounded it and it was 155 hours

Answer:

276

Step-by-step explanation:

Answer:

If the rational number is a fraction (of course) divide it. For example, 1/2 can be divided as 1 divided by 2 which is 0.5.

If the number is an integer, you can simply just add .0 (point zero). For example, if the rational number is 12, the decimal version would be 12.0.

If the number is a fraction, you can divide the numerator by the denominator. For example, if the rational number is 1/10 (one tenth), just can divide one by zero to get 0.1 (zero point one).

Answer:

The dimensions have to be reduced by 2 inches

Step-by-step explanation:

Given that the dimensions are: 6 by 8 inches which means that the area is 48 square inches.

Let x be the amount to make a new photo which is half of the area that means

The new dimensions will be: (8-x) by (6-x) and as the area is half

The area of new photo will be: 48/2 = 24

Putting it mathematically

[tex](8-x)(6-x) = 24\\8(6-x)-x(6-x)=24\\48-8x-6x+x^2=24\\48-14x+x^2=24\\x^2-14x+48-24=0\\x^2-14x+24=0\\x^2-12x-2x+24=0\\x(x-12)-2(x-12)=0\\(x-2)(x-12)=0\\x-2=0 => x=2\\x-12=0 =>x=12[/tex]

Subtracting 12 from both dimensions will make them negative so 12 cannot be the solution.

Hence,

The dimensions have to be reduced by 2 inches

We want to see by how much we must reduce the dimensions of the photograph in order to reduce its area to half. We will find that we must reduce each measure by 2 inches.

The original measures of the photograph are:

Then the area is:

A = (6 in)*(8 in)  = 48 in^2

Now we want to define a new length and a new width:

such that:

A' = L'*W' = 24 in^2

      (6 in - n)*(8in - n)  = 24 in^2

      48in^2 - n*14 in + n^2 = 24 in^2

    n^2 - n*14 in + 24in^2 = 0

This is a quadratic equation, we can solve this for n by using Bhaskara's formula, we will get:

[tex]n = \frac{14in \pm \sqrt{(-14)^2 - 4*1*24in^2} }{2*1} \\\\n = 7in \pm 5 in[/tex]

The only solution that makes sense is:

n = 7in -  5in = 2in

This means that we need to reduce each measure by 2 inches.

Answer:

(-9,-2)

Step-by-step explanation:

The translated coordinates are (-1,4).

The process of changing the location of the image on the coordinate system will be known as the translation. The translation is done on the coordinate plane a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

Given that A sergeant received an order to relocate the squad from its current location T (3, -2) on the coordinate plane to a new location S. The movement of the squad is described by the translation (x, y)⟶(x-4, y+6).

The translated points will be calculated as below:-

( 3, -2 ) ⇒ [ ( 3 - 4 ) , ( -2 + 6 ) ]

( 3, -2 ) ⇒ [ ( -1 ) , ( 4 ) ]

Therefore, the translated coordinates are (-1,4).

The population of fish in a lake was approximately 5.4 * 10 ^ 4 in 2012.

The approximate population of fish in this in 2013 since the amount of the fish tripled is 1.62 × 10⁵

Scientific notation is the proper format of denoting and representing large numbers into simpler forms multiplied by raising them to the power of 10.

Given that:

In 2013, when the population of the fish tripled the amount it was in 2012;

Then, we can calculate the total population of fish in 2013 as:

[tex]\mathbf{=( 5.4 \times 10^4) \times 3}[/tex]

= 162000

= 1.62 × 10⁵

Therefore, we can conclude that the approximate population of fish in 2013 is: 1.62 × 10⁵

3x - 2 = 2x - 3

Subtract 2x from both sides:

3x - 2x - 2 = 2x - 2x - 3

x - 2 = - 3

Add 2 to both sides:

x - 2 + 2 = -3 + 2

x = -1

Therefore, the equation only has ONE solution.
