Answer:

Dimensions of rug:

Length = 28 ft

Width =  27 ft

Step-by-step explanation:

The given dimensions of the room is:

Length = 30 ft

Width = 29 ft

Area of carpeting = 756 sq ft

Kindly refer to the attached image.

Let the uniform strip around floor is of length = [tex]x[/tex] ft

This [tex]x[/tex] feet will be 2 times along the length and

2 times along the width of room.

So, length of rug = 30 -2 [tex]\times[/tex] [tex]x[/tex] and

Width of rug = 29 -2 [tex]\times[/tex] [tex]x[/tex]

It will be rectangular in shape.

Area of a rectangle is given as:

[tex]A = Length\times Width[/tex]

[tex]756 = (30-2x) (29-2x)\\\Rightarrow 756 = 870 - 118x+4x^2\\\Rightarrow 4x^2-118x+114=0\\\Rightarrow 2x^2-59x+57=0\\\Rightarrow 2x^2-57x-2x+57=0\\\Rightarrow x =1, -\dfrac{57}{2}[/tex]

Negative length not possible.

So,Length of strip,  [tex]x = 1\ ft[/tex]

Dimensions of rug:

Length = 30 -2 = 28 ft

Width = 29 -2 = 27 ft

Answer:

Step-by-step explanation:

Answer:

[tex]f^{-1}[/tex](x) = (x - 2)² - 6

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = [tex]\sqrt{x+6}[/tex] + 2 ( subtract 2 from both sides )

y - 2 = [tex]\sqrt{x+6}[/tex] ( square both sides )

(y - 2)² = x + 6 ( subtract 6 from both sides )

(y - 2)² - 6 = x

Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus

[tex]f^{-1}[/tex](x) = (x - 2)² - 6

Answer:

Domain (-3, 4, 5)

Range (1, 2, 6)

Step-by-step explanation:

Domain is your x so all of the values that can go into a relation or function (which is your input) are called Domain. Domain is also all of the set of elements of ordered pair ( which is the x coordinates).

Range is your y so all the values that can go into a relation or function ( which is your output) are called Range. Range is also all the set of second elements of ordered pair ( which is the y coordinates).

So, basically you just look at all the number that come first so say you have

(1,2), (2,3), (3,4)

Your first numbers to each point are (1, 2, 3) which is your Domain

then look at the second number which are (2, 3, 4) which is your Range.

Hope this helps!

Hi

7 = 14.70

15= X

so :  X =  15*14.70 /7 = 31.5

15 liters  of petrol cost  31.5

The cost of 15 liters of petrol if 7 liters cost $14.70 is $31.50

To calculate the cost of 15 liters of petrol if 7 liters of petrol cost $14.70,

First, we will determine the cost of 1 liter of petrol.

From the question,

7 liters of petrol cost $14.70

That is,

7L = $14.70

Then,

1 L = $14.70 ÷ 7

1 L = $2.10

∴ The cost of 1 liter of petrol is $2.10

Now, for the cost of 15 liters of petrol, we will multiply the unit price ($2.10) by 15

That is,

The cost of 15 liters of petrol = 15 × $2.10

∴ The cost of 15 liters of petrol = $31.50

Hence, the cost of 15 liters of petrol if 7 liters cost $14.70 is $31.50

Answer:

The number of yellow skittles in the bag is 15 yellow skittles

Step-by-step explanation:

The ratio of yellow to blue skittles in the bag is 5:9

The number of blue skittles in the bag = 12 + The number of yellow skittles in the bag

From the ratio of yellow to blue skittles in the bag, we have;

Fraction of the total skittles that are yellow = 5/(5 + 9) = 5/14

Fraction of the total skittles that are blue = 9/14

Whereby placing the number of yellow skittles as Y, and the number of blue skittles as B we have;

The number of blue skittles = Y + 12

The total number of skittles = Y + Y + 12 = 2·Y + 12

Whereby the fraction of the total skittles that are blue = 9/14, we have

9/14 × (2·Y + 12)  = Y + 12

9 × (2·Y + 12) = 14 × (Y + 12)

18·Y + 108 = 14·Y + 168

18·Y - 14·Y = 168 - 108 = 60

4·Y = 60

Y = 60/4 = 15

∴ The number of yellow skittles in the bag = 15

The number of blue skittles is given as = Y + 12 = 15 + 12 = 27.

Answer:

Step-by-step explanation:

Given the numbers 37.5%, 1/3, 0.3, 40%, 3/5, before we can order the numbers from the least to greatest, we need to first express al the values in percentage.

For 1/3;

= 1/3 * 100

=  100/3

= 33.3%

For 0.3:

= 0.3 * 100

= 3/10*100

= 30%

for 3/5;

= 3/5 * 100

= 300/5

= 60%

Hence the numbers in percentage are . 37.5%, 33.3%, 30%, 40%, 60%

The values from the least to the greatest in terms of percentage is 30%, 33.3%, 37.5%, 40%, 60%

In term of the given values from least to greatest is;

0.3, 1/3, 37.5%, 40%, 3/5
