Rachel uses 7.9 pints of white paint and blue paint to paint her bedroom walls. 3 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?

the sum of all the angles = 180

13x-11 + 8x-9 + 30x-4 =180

51x-24 = 180

51x = 204

x=4

w= 8x-9= 8×4-9

= 2e°

Answer:

23°

Step-by-step explanation:

First, note that the sum of angles in a triangle is 180°.

So, m∠W + m∠B + m∠T = 180°

Substitute the measures.

(8x - 9) + (13x - 11) + (30x - 4) = 180

Simplify.

8x + 13x + 30x - 9 - 11 - 4 = 180

51x - 24 = 180

Add 24 to both sides.

51x = 204

Divide both sides by 51.

x = 4

Then, substitute x = 4 into m∠W

8x - 9 = 8 * 4 - 9 = 32 - 9 = 23°

So, m∠W = 23°

Answer:

1 = 3

2 = 6

3 = 9

Step-by-step explanation:

for every # it is multiplied by 3 (ex. 7 • 3 = 21, 8 • 3 = 24, ect.)

therefore if it is multiplied by 3 each time

then 1 • 3 = 3

2 • 3 = 6

and 3 • 3 = 9

hope this helps :)

Answer: 4311/9900 or 479/1100

Step-by-step explanation:

Okie so in order to do this, we need to get rid of the repeating part of the decimal

==============================================================

Right now we have x = 0.435454545454...

If we multiply this by 100, we get

100x = 43.545454545454

And if we multiply by 10000 we get

10000x = 4354.5454545454

==============================================================

Subtract the two equations

10000x = 4354.5454545454

100x = 43.545454545454

------------------------------------------------- (notice: the repeating part will cancel out)

9900x = 4311

x = 4311/9900

If you simplify the fraction you get: 479/1100

The fraction that represents the repeating decimal is

[tex]\frac{479}{1100}[/tex]

Given :

A repeating decimal  [tex]0.4354545454...............[/tex]

there is bar at 54 , so 54 is repeating

We need to convert this decimal into fraction

54 is repeating so we multiply by 100

Let x= [tex]0.4354545454...............\\[/tex]

[tex]100x=43.54545454...............[/tex]

Now we subtract x from 100x

[tex]100x=43.54545454...............\\ x= 0.4354545454...............\\-----------------------------------------\\ 99x=43.11[/tex]

Now divide both side by 99

[tex]x=\frac{43.11}{99} \\[/tex]

multiply top and bottom by 100 to remove the decimal

[tex]x=\frac{4311}{9900} \\Divide \; top \; and \; bottom \; by 9\\x=\frac{479}{1100}[/tex]

Answer:

D) 5.52

Step-by-step explanation:

[tex]\frac{AB}{BC} =\frac{DE}{EF} \\\\\frac{x}{2.3} =\frac{2.4}{1} \\\\x=5.52[/tex]

Answer: 5.52

Step-by-step explanation:

Answer:

See below for the matrix

D = 100

Step-by-step explanation:

[tex]\left[\begin{array}{cccc}3&2&1&-8\\-1&-2&4&7\\1&-6&-3&15\end{array}\right][/tex]

         3    2    1

D =   -1    -2    4    =   3(-2)(-3) + 2(4)(1) + 1(-1)(-6)  

         1    -6   -3

                                    - 1(-2)(1) - 3(4)(-6) - 2(-1)(-3)

                           =  18 + 8 + 6 + 2 + 72 - 6

                           =  100

Answer: 28

Step-by-step explanation:

Let the number of balloons that she had last party be represented by x.

Since Mrs.Hines has 40 ballons for a party which was 12 more balloons than she had for her last party. The number of ballons had last party will be formed into an equation as:

x + 12 = 40

Collect like terms

x = 40 - 12

x = 28

She had 28 balloons last year

Answer:

1.25π

Step-by-step explanation:

Hello There!

The area of a sector can be found using this formula

[tex]A=\frac{0}{360} \pi r^{2}[/tex]

where 0 = angle and r = radius

so given the measures r = 3 and 0 = 50 all we have to do is plug in the values into the formula

so...

[tex]A=\frac{50}{360} \pi 3^{2} \\3^{2}=9 \\\frac{50}{360} 9=1.25[/tex]

so the area of the sector = 1.25π

Note: it says to leave your answer in terms of pi so we do not have to apply pi

Answer:

The common factor is 5x.

The factored polynomial is: [tex]5x(7x - 2)[/tex]

Step-by-step explanation:

Factor of the numbers:

The common factor of the numbers 5, 30 and 10 is 5, as it is the greater common divisor of them, as found below:

5 - 30 - 10|5

1 - 6 - 2

Factor of the exponents:

Between [tex]x^2, x^2[/tex] and [tex]x[/tex], the common factor is the x with the lowest exponent. So x

Common factor

Number multiplied by exponents, so 5x.

Factoring the polynomial:

[tex]5x^2 + 30x^2 - 10x = 5x(\frac{5x^2}{5x} + \frac{30x^2}{5x} - \frac{10x}{5x}) = 5x(x + 6x - 2) = 5x(7x - 2)[/tex]

The factored polynomial is: [tex]5x(7x - 2)[/tex]

Step-by-step explanation:

Answer:

x= 154°

Step-by-step explanation:

since the interior angle sum of a triangle is 180°, we can subtract the interior angles we already have from 180°

so, 180-108-46= 26° which gives us our missing interior angle.

then, we see the straight line is 180° where we need x.

so, we subtract 26 from 180 which leaves us with 154.

therefore, x= 154°
