The graph shows the career interests of the students at Linda’s school. Suppose there are 400 students at the school. How many of them want to be an athlete? (Example 1)

Answers

Step-by-step explanation:

Percentage of students who want to be an athlete

= 12%.

400 students * (12%/100%) = 48 students.

Hence 48 students want to be an athlete.

The number of athletes students which are 12% of 400 students will be 48.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The graph shows the career interests of the students at Linda’s school. Suppose there are 400 students at the school.

From the graph, the percentage of athletes is 12%.

The number of athletes students which are 12% of 400 students will be given as,

⇒ 12% x 400

⇒ 0.12 x 400

⇒ 48

The number of athletes students which are 12% of 400 students will be 48.

Find the value of x that will make L parallel to m

Answers

Answer:

x = 7

Step-by-step explanation:

If L is parallel to M, therefore:

7x - 7 = 4x + 14 (alternate interior angles are congruent)

7x - 7 - 4x = 4x + 14 - 4x (subtraction property of equality)

3x - 7 = 14

3x - 7 + 7 = 14 + 7 (addition property of equality)

3x = 21

Divide both sides by 3

x = 7

Step-by-step explanation:

Put each term in 6+(-9-6 x)/3-x over the common denominator 3: 6+(-9-6 x)/3-x  =  18/3+(-9-6 x)/3-(3 x)/3:

18/3+(-9-6 x)/3-(3 x)/3 = 0

18/3+(-9-6 x)/3-(3 x)/3 = (-3 x+(-9-6 x)+18)/3:

(-3 x-6 x-9+18)/3 = 0

Grouping like terms, -3 x-6 x-9+18 = (18-9)+(-6 x-3 x):

((18-9)+(-6 x-3 x))/3 = 0

-6 x-3 x = -9 x:

(-9 x+(18-9))/3 = 0

18-9 = 9:

(9-9 x)/3 = 0

Multiply both sides of (9-9 x)/3 = 0 by 3:

(3 (9-9 x))/3 = 3×0

(3 (9-9 x))/3 = 3/3×(9-9 x) = 9-9 x:

9-9 x = 3×0

0×3 = 0:

Answers

Answer:

12.5

Step-by-step explanation:

We can turn this into a cross - multiplication problem.

n / 7.5 = 25 / 15

All we have to do is cross multiply to get 15n = 7.5*25

As a result, we get 15n = 187.5

Divide by 15 on both sides to get 12.5

Double check

We can double check this answer by dividing 15/7.5 and 15/7.5, because ratios are the same if they are just multiplied versions of themselves

So, we get 2 for both answers, meaning that 12.5 is correct

Which is the equation of the line that passes through the point (-4,3) and (2,6)

Answers

Answer:

[tex]\displaystyle y = \frac{1}{2}x + 5[/tex]

Step-by-step explanation:

Equation of a Line

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

Suppose a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:

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

We'll use the points (-4,3) and (2,6), thus:

[tex]\displaystyle m=\frac{6-3}{2+4}=\frac{3}{6}=\frac{1}{2}[/tex]

Now we use the point-slope form using the point (2,6):

[tex]\displaystyle y - 6 = \frac{1}{2}( x - 2 )[/tex]

Operating:

[tex]\displaystyle y - 6 = \frac{1}{2}x - 1[/tex]

[tex]\displaystyle y = \frac{1}{2}x - 1 + 6[/tex]

[tex]\boxed{\displaystyle y = \frac{1}{2}x + 5}[/tex]

Answers

Answer:

z = 66

Step-by-step explanation:

RS = z

QT = z - 33

Based on the midsegment theorem, QT = ½(RS)

Plug in the values

z - 33 = ½(z)

Multiply both sides by 2

2(z - 33) = z

2z - 66 = z

Add 66 to both sides

2z = z + 66

Subtract z from both sides

2z - z = 66

z = 66

To obtain information about the employment status of the workforce, the U.S. Bureau of the Census conducts what is known as the Current Population Survey. Each month interviewers visit about 59,000 of the 98 million households in the United States and question the occupants over 14 years of age about their employment status. Their responses enable the Bureau of the Census to estimate the percentage of people in the labor force who are unemployed (the unemployment rate). In the figure, solve for x and y. The Ancient Chinese were famous for their inventions and technology. Many of their inventions had lasting impact on the entire world. Other inventions led to great feats of engineering like the Grand Canal and the Great Wall of China.Firing a rocket using gunpowder The Diamond Sutra is the world's oldest Printed BookHere are some of the notable inventions and discoveries made by the engineers and scientists of Ancient China:Silk - Silk was a soft and light material much desired by the wealthy throughout the world. It became such a valuable export that the trade route running from Europe to China became known as the Silk Road. The Chinese learned how to make silk from the cocoons of silkworms. They managed to keep the process for making silk a secret for hundreds of years.Paper - Paper was invented by the Chinese as well as many interesting uses for paper like paper money and playing cards. The first paper was invented in the 2nd century BC and the manufacture later perfected around 105 AD. (Modern paper, not papyrus paper).Printing - Wood block printing was invented in AD 868 and then moveable type around 200 years later. This was actually hundreds of years before the invention of the printing press by Gutenberg in Europe.The Compass - The Chinese invented the magnetic compass to help determine the correct direction. They used this in city planning at first, but it became very important to map makers and for the navigation of ships.Gunpowder - Gunpowder was invented in the 9th century by chemists trying to find the Elixir of Immortality. Not long after, engineers figured out how to use gunpowder for military uses such as bombs, guns, mines, and even rockets. They also invented fireworks and made great beautiful displays of fireworks for celebrations.Boat Rudder - The rudder was invented as a way to steer large ships. This enabled the Chinese to build huge ships as early as 200 AD, well before they were ever built in Europe.Other - Other inventions include the umbrella, porcelain, the wheelbarrow, iron casting, hot air balloons, seismographs to measure earthquakes, kites, matches, stirrups for riding horses, and acupuncture.Fun Facts Gunpowder, paper, printing, and the compass are sometimes called the Four Great Inventions of Ancient China. Kites were first used as a way for the army to signal warnings. Umbrellas were invented for protection from the sun as well as the rain. Chinese doctors knew about certain herbs to help sick people. They also knew that eating good foods was important to being healthy. Compasses were often used to make sure that homes were built facing the correct direction so they would be in harmony with nature. The Grand Canal in China is the longest manmade canal or river in the world. It is over 1,100 miles long and stretches from Beijing to Hangzhou. They invented the abacus in the 2nd century BC. This was a calculator that used sliding beads to help compute math problems quickly. A clear coating called lacquer was made to protect and enhance certain works of art and furniture.
