What is the value of x?
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

If paper products accounted for 33% of the total MSW recycled in 2010 and about 7m3 of landfill space is saved for each metric ton of paper products recycled, calculate how much landfill space was saved by recycling paper products in 2010 in the United States.
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.
What is a proportion?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.

Answer:
July 16
Step-by-step explanation:
The way to solve this problem is to look carefully at the question and then work through each statement in turn and see what we can deduce from it.
From the question we know that Albert has been told May, June, July or August.
Bernard has been told 14, 15, 16, 17, 18, or 19.
Albert: I don't know when Cheryl's birthday is, but I know that Bernard does not know too.
Bernard has been told the day of Cheryl's birthday. There are only two days, 18 and 19 that appear once on Cheryl's list. This means that Cheryl's birthday cannot be May 19th or June 18th as if it was then Bernard would know the answer.
Remember that Albert has been told a month and from the statement he knows that Bernard does not know the birthday. For Albert to be certain that Bernard does not know Cheryl's birthday, the month Albert had been told must not have been May or June.
Therefore Cheryl's birthday must fall in July or August.
Bernard: At first I don't know when Cheryl's birthday is, but I know now.
Based on the above Bernard has worked out that Cheryl's birthday is in July or August.
If Bernard now knows Cheryl's birthday the day he must have been told would be 15, 16 or 17. It cannot be 14 as this falls in both July and August and as such he wouldn't know Cheryl's birthday for certain.
Albert: Then I also know when Cheryl's birthday is.
Based on the above Albert has worked out that Cheryl's birthday is one of the following:
July 16
August 15
August 17
If Albert now knows for certain when Cheryl's birthday is he must have been told the month of July, as if it was August there would be two possible options.
Therefore the answer is July 16.

Which is the graph of y=[x]-2?
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.
Calculate the sum of the first 20 terms of an arithmetic sequence with the 3rd term 8 and the 8th term 143.
Answer:
4670
Step-by-step explanation:
that is the workings above
If the third term is 8 and eighth term is 143 then the sum of first 20 terms is 4210.
What is arithmetic progression?Arithmetic progression is a sequence in which all the terms have equal differences. Nth term will be a+(n-1)d in which a is first term, d is difference and n is number of term.
How to calculate sum?We have been given that third term is 8 and eight term is 143 and we have to calculate the sum of first 20 terms.
[tex]A_{3}[/tex]=a+(3-1)d
8=a+2d-----1
[tex]A_{8}[/tex]=a+(8-1)d
143=a+7d---2
Subtract equation 1 from equation 2.
a+7d-a-2d=143-8
5d=135
d=27
Put the value of d in equation 1.
a+2d=8
a+2*27=8
a+54=8
a=-46
We know that,
[tex]S_{n}[/tex]=n/2[2a+(n-1)d]
=20/2[2*(-46)+(20-1)*27]
=10(-92+19*27)
=10(-92+513)
=10*421
=4210
Hence if the third term is 8 and eighth term is 143 then the sum of first 20 terms is 4210.

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 139 millimeters, and a variance of 49. If a random sample of 34 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by greater than 1.8 millimeters
The probability that the sample mean would differ from the population mean by more than 1.8 millimeters is approximately 0.0668.
What is the standard deviation?A standard deviation (σ) is a measure of the distribution of the data in reference to the mean.
The standard deviation of the population is [tex]$\sqrt{49} = 7$[/tex] millimeters. The standard error of the sample mean is then
[tex]$\frac{7}{\sqrt{34}} = \frac{7}{5.874} \approx 1.2$[/tex]millimeters.
The probability that the sample mean would differ from the population mean by more than 1.8 millimeters is the probability that it falls outside of the interval [tex]$(139 - 1.8, 139 + 1.8)$[/tex]. We can use the standard normal distribution to approximate this probability.
First, we need to convert the difference between the sample mean and the population means to standard units.
The difference of 1.8 millimeters is :
[tex]$\frac{1.8}{1.2} = 1.5$[/tex] standard units.
Then, we can use the standard normal distribution to find the probability that the sample mean falls outside of this interval.
This probability is equal to [tex]$1 - 2\Phi(-1.5) \approx 0.0668$[/tex],
where [tex]$\Phi$[/tex] is the standard normal cumulative distribution function.
Therefore, the required probability is approximately 0.0668.

Find the mean absolute deviation (MAD) of the data in the pictograph below. home runs - 1 home run Home runs hit by each team in a baseball league
The mean absolute deviation of the data in the image given is: 1.5.
What is the Mean Absolute Deviation?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

Company is preparing budgets for the quarter ending June 30, 2019.
Budgeted sales in units for the next five months are:
April 20,000
May 50,000
June 30,000
July 25,000
Required:
a. Prepare Sales budget for April, May & June assuming selling price per unit is 15.
b. Prepare production budget for April, May & June if the company wishes ending inventory as 10 % of next month sales units.
Answer:
Results are below.
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
