Answer:

x = 2.16

Step-by-step explanation:

Question :

[tex]\frac{3.5x}{9} =\frac{4.2}{5}[/tex]

Use cross multiplication.

3.5x × 5 = 9 × 4.2

17.5x = 37.8

Divide both sides by 17.5.

x = 2.16

The factor of the provided polynomial with the after the factorization process are similar to option C, which is

[tex](9a^3+10)(9a^3-10)[/tex]

Factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.

The given polynomial equation in the problem is,

[tex]81a^6 - 100[/tex]

The above equation has the unknown variable a and the power of this unknown variable is 6. Write down the above equation in the squared form as,

[tex](9)^2(a^3)^2 - 10^2\\(9a^3)^2-10^2[/tex]

By the difference of squared formula, the above polynomial can be written as,

Step-by-step explanation:

Let's answer Part A first.

The final cost of the rental will be called X

x = (37.45 * 10) + 78

x  = 374.50 + 78

x = $452.50

Part B:

There is no cost for mileage.

Answer:

13.4

Step-by-step explanation:

AB =2DC

So, DC=AB/2

Now, AB/AC=DE/DC

AB/28=13/(AB/2)

AB²=13×28×2

AB=√728

AB=26.98

now, DC=AB/2

=13.4

The length of DC is √182.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

DE is parallel to AB.

If AB is twice the length of DC, AC = 28, and DE = 13

We have to find the length of DC

DC/AC=DE/AB

x/28=13/2x

Apply cross multiplication

2x²=13×28

2x²=364

Divide both sides by 2

x²=364/2

x²=182

x=√182

Hence, the length of DC is √182.

Answer:

y = 3x + 1

Step-by-step explanation:

You have to use y = m x + c to find the equation of the line.

Here,

m ⇒ slope

c  ⇒  y - intercept

First let us find the slope by using the below formula.

For that, let us use the given coordinates.

( -1 , -2 ) ⇒ ( x₁ , y₁ )

(-2 , -5)  ⇒  ( x₂ , y₂ )

m = [tex]\frac{y_1-y_2}{x_1-x_2}[/tex]

m = [tex]\frac{-2-(-5)}{-1-(-2)}[/tex]

m = [tex]\frac{-2+5}{-1+2}[/tex]

m = [tex]\frac{3}{1}[/tex]

m = 3

Now we have to find the y - intercept.

For that we can use any coordinate for that.

Let us use ( -1 , -2 ) coordinate.

y = m x + c

-2 = 3 × -1 + c

-2 = -3 + c

- 2 + 3 = c

1 = c

Let us write the equation of the line now.

y = m x + c

y = 3 x + 1

Answer:

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

30% = 30/100 = 30 ÷ 100 = 0.3.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 30% of its value.

Calculate the New Value

New value =

12 + Percentage increase =

12 + (30% × 12) =

12 + 30% × 12 =
