solve for x: 3(2x+54)-(27x-3)=56

Answers

Answer:

x = 109/21

Step-by-step explanation:

Step 1: Write equation

3(2x + 54) - (27x - 3) = 56

Step 2: Solve for x

Distribute: 6x + 162 - 27x + 3 = 56Combine like terms: -21x + 165 = 56Subtract 165 on both sides: -21x = -109Divide both sides by -21: x = 109/21

8. At the fabric store, Marisela spends $9.00
on 1 1/8yards of fabric. How much does one
yard of fabric cost?​

Answers

Answer:

6.55

Step-by-step explanation:

We know that 11/8 yards of fabric cost 9$

We need to first find what 1/8 yard of fabric costs

So you do 9/11 which gives the amount of 1/8 which is 0.818181812 and multiply that by 8 to find what the cost of one yard equals

What is the equation of the line that passes through the point (8,-8) and has a slope of -1

Answers

Answer:

y= (-1)*x

Step-by-step explanation:

lets assume that the line equation is

y=m*x +b

where m is the slope and b the independent variable that intercept Y axis.

then replacing the value of m:

y=(-1)*x + b

after that we have to look for the value of b. Its obtained replaicing the given point (8,-8):

-8 = (-1)*(8) +b

-8 = -8 + b

0 = b

Therefore the equation of the line is:

y= (-1)*x

the estimated world population in 2011 was 7 x 10^9. Of the total population, 682 million of those people were left handed. Approximately what percentage of the world population is left handed according to the 2011 estimation

Answers

Answer:

9.7 %

Step-by-step explanation:

estimated world population in 2011 = 7x10⁹

left handed = 682,000,000

find:

Approximately what percentage of the world population is left handed according to the 2011 estimation

percentage = left handed population

                           total population

B. The oxygen atoms are released from the atmosphere into space.
C. The oxygen atoms diffuse through the atmosphere and are

D. The oxygen atoms diffuse through the atmosphere and are reused
as a reactant for photosynthesis.

Answers

Answer:

I believe your answer is C, the oxygen atoms diffuse through the atmosphere and are

inhaled by animals.

Step-by-step explanation:

Plants take in water that later splits to create hydrogen and oxygen. Since plants don't need oxygen, it gets released into the atmosphere for us and other animals to breathe.

Step-by-step explanation:

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Tobias got a score of 74.7; this version has a mean of 61.7 and a standard deviation of 13. Norma got a score of 351; this version has a mean of 291 and a standard deviation of 25. Vincent got a score of 7.38; this version has a mean of 6.9 and a standard deviation of 0.4. If the company has only one position to fill and prefers to fill it with the applicant who performed best on the aptitude test, which of the applicants should be offered the job?

Answers

Answer:

Norma performed best on the aptitude test and should be offered the job.

Step-by-step explanation:

We are given that three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Tobias got a score of 74.7; this version has a mean of 61.7 and a standard deviation of 13. Norma got a score of 351; this version has a mean of 291 and a standard deviation of 25. Vincent got a score of 7.38; this version has a mean of 6.9 and a standard deviation of 0.4.

Now, to find which of the applicants should be offered the job, we have to find the z-score of each of the applicants, and the one who gets the highest z-score will get the job.

The z-score probability distribution for the normal distribution is given by;

                            Z = [tex]\frac{X-\mu}{\sigma}[/tex]  ~ N(0,1)

where, [tex]\mu[/tex] = mean and [tex]\sigma[/tex] = standard deviation

Firstly, we will find the z-score for Tobias;

The z-score of 74.7 = [tex]\frac{X-\mu}{\sigma}[/tex]

                                 = [tex]\frac{74.7-61.7}{13}[/tex] = 1

Now, we will find the z-score for Norma;

The z-score of 351 = [tex]\frac{X-\mu}{\sigma}[/tex]

                               = [tex]\frac{351-291}{25}[/tex] = 2.4

Now, we will find the z-score for Vincent;

The z-score of 7.38 = [tex]\frac{X-\mu}{\sigma}[/tex]

                                 = [tex]\frac{7.38-6.9}{0.4}[/tex] = 1.2      

As we can clearly see that the z-score is highest for Norma which means that Norma performed best on the aptitude test and should be offered the job.

The smaller angle = 20

The larger angle = 70

Step-by-step explanation:

1/4 of a circle is  90 degrees

90 = 10x+ 20x+30

Combine like terms

90 = 30x+30

Subtract 30 from each side

90-30 = 30x+30-30

60 = 30x

Divide each side by 30

60/30 = 30x/30

2= x

10x = 10*2 = 20

20x+30 = 20*2 + 30 = 30+30 = 70

It can be answered with only a few words. It reveals background information about the subject. It draws out interesting information about the topic. Consider two neighboring island countries called Euphoria and Bellissima. They each have 4 million labor hours available per week that they can use to produce jeans, corn, or a combination of both. The following table shows the amount of jeans or corn that can be produced using 1 hour of labor.Country Jeans Corn (Pairs per hour of labor) (Bushels per hour of labor)Euphoria 5 20Bellissima 8 16Initially, suppose Bellissima uses 1 million hours of labor per week to produce jeans and 3 million hours per week to produce corn, while Euphoria uses 3 million hours of labor per week to produce jeans and 1 million hours per week to produce corn. Consequently, Euphoria produces 15 million pairs of jeans and 20 million bushels of corn, and Bellissima produces 8 million pairs of jeans and 48 million bushels of corn. Assume there are no other countries willing to trade goods, so in the absence of trade between these two countries, each country consumes the amount of jeans and corn it produces.Euphorias opportunity cost of producing 1 pair of jeans is of corn, and Bellissima's opportunity cost of producing 1 pair of jeans is of corn. Therefore, has a comparative advantage in the production of jeans, and has a comparative advantage in the production of corn.Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. In this case, the country that produces jeans will producemillion pairs per week, and the country that produces corn will producemillion bushels per week.In the following table, enter each country's production decision on the third row of the table (labeled "Production"). Euphoria Bellissima Jeans Corn Jeans Corn (Millions of pairs) (Millions of bushels) (Millions of pairs) (Millions of bushels)Without TradeProduction 15 20 8 48Consumption 15 20 8 48With TradeProduction Imports/Exports Consumption Gains from TradeIncrease in Consumption Suppose the country that produces jeans trades 18 million pairs of jeans to the other country in exchange for 54 million bushels of corn.In the previous table, use the dropdown menus across the row labeled "Imports/Exports" to select the amount of each good that each country imports and exports. Then enter each countrys final consumption of each good on the line labeled "Consumption."When the two countries did not specialize, the total production of jeans was 23 million pairs per week, and the total production of corn was 68 million bushels per week. Because of specialization, the total production of jeans has increased bymillion pairs per week, and the total production of corn has increased bymillion bushels per week.Because the two countries produce more jeans and more corn under specialization, each country is able to gain from trade.Calculate the gains from tradethat is, the amount by which each country has increased its consumption of each good relative to the first row of the previous table.
