The right response is Perimeter, x - 2y = 9.

The parameters listed in the question are:

A rectangle's perimeter is equal to 6 x – 2, its length to 2 x + 4, and its width to 2 y + 4.

The perimeter is calculated using the following formula: 2(L) + 2 (W)

6x - 2 = 2(2x + 4) + 2(2y +4) = 4x + 8 + 4y + 8

The result is: x - 2y = 9 and 2x - 4y = 18.

Consequently, the right response is x - 2y = 9.

The sum of a polygon's sides is what is referred to as its perimeter. For the perimeter calculation, the shape must be closed. And the polygonal shapes are either one- or two-dimensional.

The perimeter of the polygon is 232 units

From the question, we are to determine the perimeter of the regular polygon

From the diagram,

One of the polygon's side length is (4/3)x - 1/3

and another side length is x + 7

Since the figure is a regular polygon, we can write that

(4/3)x - 1/3 = x + 7

Now, solve for x

(4/3)x - 1/3 = x + 7

Multiply through by 3

4x - 1 = 3x + 21

4x - 3x = 21 + 1

x = 22

One of the polygon's side length is x + 7

∴ One side length = 22 + 7

One side length = 29

Since the polygon has 8 sides,

The perimeter of the polygon will be

8 × 29

= 232 units

Hence, the perimeter of the polygon is 232 units

A circle is a round-shaped figure that has no corners or edges. If a circular mosaic has radius 3 meters then the area is 28.26 square meters.

A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.

Given that a circular mosaic has radius 3 meters.

We need to find the area of circular mosaic.

Area of circle=πr²

Here r=3

π=3.142

Substitute the values of pi and r in Area formula

Area =3.142*3²

=3.142*9

=28.26

Therefore area of circular mosaic is 28.26 square meters.

If a function is onto, then its domain can be a set of all non negative real numbers if the function is defined as y = √ x.

It is not necessary that function that is onto should have the domain as non negative real numbers only.
It can also have negative real numbers in its domain.

If the function is of the form:

y = √ x

Then the function will have a domain that is non negative real numbers.

But if function is of the form:

y = x²

Then it can have the domain as all real numbers.

Therefore, we get that, if a function is onto, then its domain can be a set of all non negative real numbers if the function is defined as y = √ x.

Answer:

Step-by-step explanation:

In order to cancel the coefficient of P you have to divide both sides by the coefficient not add the coefficient to both sides.

-2/3p = 4

-2/3p / -2/3 = 4 / -2/3    (Multiply both sides by -2/3 to isolate p)

p = 4 / 2/3     ([tex]\frac{4}{1} (-\frac{2}{3} ) = -\frac{8}{3}[/tex])(keep change reciprocate)

If Henry and Emma want to buy a total of 0.5 yds of fabric and the fabric costs $8.72 per yard then the amount each will pay if they want to split the cost evenly is equal to $2.18.

The amount Henry and Emma will have to pay if they want to split the cost can be calculated by using division.

First, we calculate the cost of 0.5 yards of fabric.

1 yard of fabric cost = $8.72

0.5 yards of fabric cost = x

Here x is the cost of 0.5 yards of fabric

8.72 × 0.5 = x

x = $4.36

As the cost of 0.5 yards of fabric is calculated to be $4.36, the amount each will pay if they want to split the cost evenly can be found by dividing the cost of 0.5 yards by 2.

cost of 0.5 yards of fabric / 2 = 4.36 / 2 = $2.18.

Hence each one of them will pay $2.18 if they want to split the cost evenly.

The total capacity of pool in gallons is 1625.

Let us assume the water in the pool be x liters. Forming the equation according as per the statement in question -

x + 300 = 80% of total volume - Equation 1

Forming the equation according to second statement -

30% × x = 300

30/100 × x = 300 - Equation 2

Finding the initial volume of water using equation 2-

x = 300×100/30

Cancelling zero and performing division and multiplication to find the initial volume of water

x = 1000 gallons

Now finding the total volume or capacity of pool by keeping the value of x in first equation -

1000 + 300 = 80/100 × total volume

Total volume = 1300×100/80

Performing multiplication and division to find the total capacity of pool

Total capacity of pool = 1625 gallons

Hence, the total capacity of pool in gallons is 1625.

Step-by-step explanation:

yes, it is a good deal as long as you use the card before a year.

Let's see how much you will save if you pay the $150.

If you want 6 hair cuts, you need to pay $30 6 times, so the total cost will be:

C = $30*6 = $180

If instead, you prepay $150, then you get the 6 cuts only for $150, saving a total of $30 (but the downpayment is 5 times larger than in the other case), but only if you plan to use the punch card for the other cut in the year, if you don't then this option does not make sense.

The result of simplifying the expression (x²/x⁻¹¹)¹/₃ using the exponent rules is [tex]\sqrt[3]{}[/tex](x¹³)

To solve this exercise we have to resolve algebraic operations following the exponent rules.

(x²/x⁻¹¹)¹/₃

Using the quotient rule that indicates that: the exponent result will be the subtraction of these exponents, we have:

(x⁽²⁻⁽⁻¹¹⁾)¹/₃

(x⁽²⁺¹¹⁾)¹/₃

(x¹³)¹/₃

Using the power of a power rule that indicates that: the exponent result will be the multiplication of these powers, we have:

x⁽¹³*¹/₃⁾

x⁽¹³/₃⁾

As we have a fractional exponent, you must convert the exponent to root:

[tex]\sqrt[3]{}[/tex](x¹³)
