pic is there answer 20 points

Answer:

20

Step-by-step explanation:

You can write the equation x+(3x+1)+(x-11)=90 and then isolate x

x+(3x+1)+(x-11)=90

5x-10=90 (combine like terms)

5x-10+10=90+10 (add 10, addition property of equality)

5x=100

5x/5=100/5 (divide by five, division property of equality)

x=20

The answer will be option D. -6

Answer:

  9°, 9°, 162°

Step-by-step explanation:

Let x represent the measure of the first angle. Then the sum of all of the angles in the triangle is ...

  x + x + 9(x+x) = 180°

  20x = 180° . . . . . . . . . . collect terms

  x = 180°/20 = 9° . . . . . divide by 20

  9(x+x) = 162° . . . . . . . find the third angle

The three angle measures are 9°, 9°, and 162°.

Circumference= 2 pi x r

Diameter= 9 (double the radius)

Radius= 4.5

Pi= 3.14

2 x 3.14= 6.28

Step-by-step explanation:

First, we need to determine the sales budget for April, May, and June:

Sales budget April:

Number of units sold= 20,000

Sales revenue= 20,000*15= $300,000

Sales budget May:

Number of units sold= 50,000

Sales revenue= 50,000*15= $750,000

Sales budget June:

Number of units sold= 30,000

Sales revenue= 30,000*15= $450,000

Now, the production budget using the following formula:

Production= sales + desired ending inventory - beginning inventory

Production budget April:

Sales= 20,000

Desired ending inventory= 50,000*0.1= 5,000

Beginning inventory= 0 (assuming no beginning inventory)

Production= 25,000

Production budget May:

Sales= 50,000

Desired ending inventory= 30,000*0.1= 3,000

Beginning inventory= (5,000)

Production= 48,000

Production budget June:

Sales= 30,000

Desired ending inventory= 25,000*0.1= 2,500

Beginning inventory= (3,000)

Production= 29,500

Answer:

45 degree

Step-by-step explanation:

3x - 9 + 24 + 30 = 180 degree (being sum of interior angles of a triangle)

3x + 45 = 180

3x = 180 - 45

x = 135/3

x = 45 degree

Answer:45 độ

Step-by-step explanation:

3x - 9 + 24 + 30 = 180 độ (là tổng 3 góc của tam giác)

3x + 45 = 180

3x = 180 - 45

x = 135/3

x = 45 độ

Answer:

Volume of landfill space saved by recycling paper products in 2010 in the United States = 175.56 million m³ of land space

Note: The Table in the attachment below Shows The Total MSW (in Metric Tons) And Percent MSW Recycled Over Time In The United States.

Step-by-step explanation:

Step 1: Determining the amount in metric tons of paper products recycled

In the year 2010, a total of 76 million metric tons of MSW was recycled.

Recycling of paper products accounted for 33% of the total MSW recycled in 2010.

The amount of paper products recycled in millions of metric ton = 0.33 × 76 million  = 25.08 million metric tons of paper products.

Step 2: Determining the volume of landfill space saved in 2010 by recycling paper products

7m³ of landfill space is saved for each metric ton of paper products.

Volume of landfill space saved by recycling paper products in 2010 in the United States = total amount of paper products recycled  × 7 m³/metric ton

Volume of landfill space saved = 25.08 million metric tons  × 7  m³/metric ton

Volume of landfill space saved = 175.56 million m³ of land space

Therefore, volume of landfill space saved by recycling paper products in 2010 in the United States = 175.56 million m³ of land space

Using proportions, it is found that about 21 cubic metres of landfill space was saved by recycling paper products in 2010 in the United States.

A proportion is a fraction of a total amount.

In this problem, 33% of the total amount is equivalent to 7 cubic metres, hence:

0.33t = 7

t = 7/0.33

t = 21

21 cubic metres of landfill space was saved by recycling paper products in 2010 in the United States.

Expression for area of triangle

The equation becomes

[tex]Area = \frac{1}{2} * 5* 2[/tex]

Answer:

The function y = ⌊x⌋ is called the "greatest integer value" function.

it works as follows: the input is any number x, the output is the greatest  

integer smaller or equal to x.

For example:

⌊0.1⌋=0

⌊0.26⌋=0

⌊0.4678⌋=0

⌊0.8989⌋=0

⌊0.999⌋=0

⌊1⌋=0

⌊1.0001⌋=1

so, the value of ⌊x⌋, for the entire interval (0, 1] is 0.

Similarly,  

the value of ⌊x⌋, for the entire interval (1, 2] is 1.   and so on,  

thus the graph of  y = ⌊x⌋ is as shown in picture 1

the graph of   y = ⌊x⌋ – 2   is the graph of   y = ⌊x⌋   shifted 2 units down.

check picture 2.

Answer and Step-by-step explanation:

The answer is 2 (which is equal to x).

If you were to plug 2 in to the function, the result if 30.

[tex]x^{3}+ 6x^{2} -x\\\\\\\\(2)^3+6(2)^2 - 2 = 30 = f(2)[/tex]

Step-by-step explanation:

Volume of a cuboid is given by

V = l*w*h

924 = 4 (x+1) (x+11)

FOIL

924 = 4(x^2 +11x+x+11)

924 = 4(x^2+12x+11)

Divide each side by 4

231 = (x^2+12x+11)

Subtract 231 from each side

0 = x^2 +12x +11-231

0 = x^2 +12x - 220

Factor

0 = (x+22) (x-10)

Using the zero product property

x+22 =0  x-10 =0

x=-22  x=10

We cannot have a negative length

x=10

The side lengths are 4, 10+1, 10+11

4,11,21

The longest is 21

Answer:

y = 4x+3x^2

Step-by-step explanation:

For an equation to be linear, x must have a power of 1

y = 4x+3x^2 has a power of x that is not x  ( x^2) so this is not linear  ( it is quadratic)

t > 20

Step-by-step explanation:

14 - 0.6t > 2

14 - 14 - 0.6t > 2 - 14

- 0.6t > - 12

- 0.6t ÷ - 0.6 > - 12 ÷ - 0.6

t > 20

Answer:

t<20

Step-by-step explanation:

move the constant to the right- hand side and change its sign

-0.6>2-14

calculate the differnce

-0.6> -12

divide both sides of the inequality by -.06 and flip the inequality sign

t>20

The mean absolute deviation of the data in the image given is: 1.5.

The mean absolute deviation can be described as the average distance between each data value of a data set and its mean.

Thus:

Let's find the average of the data set:

Each data in the data set are 7, 2, 4, 3.

Mean = (7 + 2 + 4 + 3)/4

Mean = 4

Therefore:

Mean absolute deviation = (|x1 - mean| + |x2 - mean| + ...)/N

(|x1 - mean| + |x2 - mean| +...) = (|7 - 4| + |2 - 4| + |4 - 4| + |3 - 4|) = 6

N = 4

Thus:

Mean absolute deviation = 6/4 = 1.5

Therefore, the mean absolute deviation of the data in the image given is: 1.5.
