Lin and Andre used different methods to find the area of a regular hexagon with 6-inch sides. Lin decomposed the hexagon into six identical triangles. Andre decomposed the hexagon into a rectangle and two triangles.


Find the area of the hexagon using each person’s method. Show your reasoning.

Answers

Answer:

108inches^2

Step-by-step explanation

.............................................

Divide the hexagon in identical triangles.

Triangle area = length × width / 2

6 × 6 = 36

36/2= 18

The area of a regular hexagon is 85.28 square inches.

Given that, Lin and Andre used different methods to find the area of a regular hexagon with 6-inch sides.

We need to find the area of a hexagon using both methods.

What is the area of a regular hexagon?

The formula for the area of a regular hexagon is (3√3 s²)/2, where 's' is the length of the side of the hexagon. Since we are talking about a regular hexagon, it should be noted that all sides are of equal length. When one side of the regular hexagon is known, the area can be calculated with the formula, Area of the hexagon = (3√3 s²)/2, where 's' is the length of the side of the hexagon.

We know that, the area of an equilateral triangle=√3/2 × a².

So, the area of an equilateral triangle= √3/2 × 6²

=18√3 square inches

Now, the area of a hexagon=6×18√3

=108√3=187.06 square inches

Area of the rectangle = length × width = 10.4 × 6 = 62.4 square inches

Area of a triangle= 1/2 × Base × Height = 1/2 × 10.4 × 2.2 = 11.44 square inches

Now, 11.44 × 2=22.88

Area of a regular hexagon =  62.4+22.88 =85.28 square inches

Therefore, the area of a regular hexagon is 85.28 square inches.

Malik jogs twice every day in a 7-day week with his friend. In the afternoon, they jog 3/5 as far as they do in the morning. At the end of one week they have jogged a total of 20 4/25 miles. How far do Malik and his friend jog in the afternoon?

Answers

Answer:

1.08 miles

Step-by-step explanation:

Given: They jog a total of 20 4/25 miles in a week.

Therefore they jog (20 4/25)/7 = 2.88 miles a day.

If x is how many miles they jog in the morning, they jog 3/5x miles in the afternoon. So 1.6x = 2.88. Divide 1.6 on both sides to get x = 1.8.

1.8 * 3/5 = 1.08 miles

3. A woman put $580 into a savings account for one year. The rate of interest on the account was 6½%. How much was the interest for the year in dollars and cents?


4. A student earned a grade of 80% on a math test that had 20 problems. How many problems on this test did the student answer correctly?


5. There are 28 students in a class. Sixteen of those students are men. What percent of the class are women?

Answers

Answer:

1 multiply 12,800 x 15 = 192,000 then divide 192,000 by 100 = 1,920 so the answer is $ 1,920

2 He paid $7200 for the wrecked car which is about 65% of the original price.

3Hence, interest over a year is $ 37.7 or 3770 cents.

4 The student answered 16 problems correctly on a math test that had 20 problems.

5 Total students in the class = 28

Number of students that are men = 16

Number of student that are women = 28 - 16 = 12

percentage of women in the class = 12 / 28 × 100

percentage of women in the class = 1200 / 28

percentage of women in the class = 42.8571428571

percentage of women in the class ≈ 42.9 %

How Lift-Offs Lift Our Spirits, by Miranda Sharon Americas space program does not get the attention it once did. It certainly doesnt generate the same excitement. From the 1950s through the 1970s, astronauts were national heroes. Children dreamed of traveling through space. Adults looked to the moon with a sense of national pride. Those days couldand shouldreturn.If average Americans search their brain, it is not hard to find arguments against space travel. It costs money. Its dangerous. We have enough problems on our planet. However, if the same Americans search their hearts, the results are different. Deep within us, we all have similar desires. Space exploration fulfills all these desires.Lets begin with curiosity. We all have it. From the time we are small children we longed to know what is in the next room, down the street, or in the next town. We are nomads, wanting to explore. We are detectives, trying to solve a mystery. We are students of life, seeking answers. The space program gives us a chance to be all those things and more. Even if we dont travel ourselves, the excitement of discoveries would again feed our thirst for something new.Another benefit of returning to space is the inspiration it provides. In the early days of space travel, America had a goal. We wanted to reach space safely and quickly. The country responded spectacularly. Teamwork and creativity reached all-time highs. Students delved deeper into science and math hoping to contribute. Heroes stepped up to bravely accept challenges. We were attempting the impossible and determined to succeed. Think of the amazing things Americans would accomplish if that inspiration returned.Perhaps the largest thing lost with a shrinking space program is perspective. Exploring space reminds us how small and fragile our planet truly is. It encourages collaboration with other countries which helps cultural differences disappear. It can reveal the effects of abusing natural resources. Looking at our Earth from a great distance gives us a unique view of our world and the effect we have upon it.Plans for Americas space program should be revisited. Exploration of our solar system should continue not for science or power or money, but the benefit of mankind. It gives us an outlet for our curiosity. It inspires our souls. It offers a perspective to help us understand our place in the universe. The benefits are as vast as space itself.Article 2: The Sky Has No Limits, by Roger T. Reynolds The state of NASAs space program has been the subject of much speculation in recent years. Debates have raged among members of Congress, business owners, and the general public. the president has expressed his thoughts on numerous occasions as well. The conversations seem to boil down to one question: Do the benefits of space travel outweigh the cost? A logical look at the question makes the answer quite apparent. NASAs space program is worth preserving at any cost.Put simply, NASA creates jobs. Jobs, in return, help the economy. A single space project can employ hundreds of workers from a high level, top security jobs to the lower level, yet important role players. Scientists are assigned to solve problems. Engineers are contracted to build prototypes. Truckers are hired to transport materials. Large corporations are paid for contributions, earning profits so they may hire more employees.The work of NASA also pays huge dividends to the environment. Studying Earth from space provides keen insight into many areas. Scientists monitor the ozone layer. They track the effects of global warming. They study patterns of dangerous storms. They test the possibility of space colonies. All of these activities offer hope to our increasingly overcrowded planet. The work of NASA often leads to advances in technology. Solving the mysteries of space creates solutions that help elsewhere. The Jaws of Life save victims in car accidents. The technology came from NASA research. The artificial heart did, as well. The list goes on. Architects, athletes, and autoworkers have benefited from space-related discoveries. NASA has enhanced everything from shoes to food. You likely come into contact with something improved by NASA nearly every day.It is impossible to list all the benefits of a thriving space program. It is equally impossible to predict how many new benefits are within our grasp. To find them, we must keep reaching for the stars. -100 points, please answer both parts-The data modeled by the box plots represent the battery life of two different brands of batteries that Mary tested.(a) What is the median value of each data set?(b) Compare the median values of the data sets.
