b. Find the total number of beads in the necklace. Explain your method for finding the total number of beads.

Answers

Answer:

Step-by-step explanation:

Well, first we are going to add the beads together.

2 + 8 + 14 + 20 = 44

Next, let's multiply the sum by 18 because there are 18 rows of 44 beads.

18 x 44 = 792

Juan's class is going to construct an outdoor garden. The garden will be in the shape of a square, Juan's teacher gave the class three
options for the area of the garden: 30 square feet, 40 square feet, or 50 square feet.
Part A
Without using a calculator, approximate the side length, to the nearest tenth of a foot, for the garden with an area of 30 square fet. Show
your work.
Part B
The other two garden options have approximate side lengths of 6.3 feet and 7.1 feet. Locate and graph the three points on a horizontal
number line to show the approximation of the side length for each option.

Answers

Answer:

Part A: 5.5

Part B: Kindly refer to the attached image for the number line representation.

Step-by-step explanation:

Given that:

Possible area of the first garden = 30 sq ft

Possible area of the second garden = 40 sq ft

Possible length of the second garden = 6.3 ft

Possible area of the third garden = 50 sq ft

Possible length of the third garden = 7.1 ft

To find:

Part A: Side length of the square with area 30 sq ft to the nearest tenth.

Part B: Locating and graphing the three points on a horizontal number line.

Solution:

Formula for area of a square:

[tex]Area =(Side)^2[/tex]

Part A: Given that area = 30 sq ft

Putting in the formula to find the value:

[tex]30=Side^2\\\Rightarrow Side = 5.477 \approx \bold{5.5\ ft}[/tex]

Part B:

Kindly refer to the attached image for the number line representation of the given two lengths and the length calculated for the first square.

The three lengths are 5.5, 6.3 and 7.1 respectively.

The three numbers to located on the graph are = 5.5, 6.3 and 7.1

(4) Abdi has two electric train sets: A and B. Each train is on its own circular track. He starts both trains at the same time. Train A returns to its starting point every 12 seconds. Train B returns to its starting point every 9 seconds. If the trains continue traveling, what is the least amount of time, in seconds, that both trains will arrive at the starting points at the same time?

Answers

Answer:

The least amount of time both trains will arrive at the starting points at the same time is 36 seconds.

Step-by-step explanation:

From the question, Train A returns to its starting point every 12 seconds and Train B returns to its starting point every 9 seconds.

First, we will determine the times the trains will return to the their starting points.

For Train A,

The second time Train A will return to its starting point will be at 24 seconds,

The third time will be at 36 seconds

The fourth time will be at 48 seconds and so on.

For Train B,

The second time Train B will return to its starting point will be at 18 seconds,

The third time will be at 27 seconds

The forth time will be at 36 seconds and so on.

Since both trains arrive at their starting points at 36 seconds,

Hence, the least amount of time both trains will arrive at the starting points at the same time is 36 seconds.

A student saves money to buy a laptop. The student already has 307.50 saved and puts aside $100 each month to help pay for the laptop. After 5 months, the total amount saved is 75% of the total cost of the laptop. How much more does the student need to save to buy the laptop rounded to the nearest cent.

Answers

Answer:

The amount the student needs to save is approximately $269.167

Step-by-step explanation:

The amount the student already has saved for his laptop = $307.50

The amount the student puts aside each month to pay for the laptop = $100

The total amount saved after 5 months = 75% of the total cost of the laptop

Therefore, we have;

The total amount the student has after 5 months = $307.5 + 5 × $100 = $807.5

The total amount saved after 5 months = 75% of the total cost of the laptop

Therefore;

$807.5 = 75% of the total cost of the laptop

The total cost of the laptop = $807.5/75% = $807.5/75 × 100 = [tex]\$ \ 1076\frac{2}{3}[/tex]

The total cost of the laptop ≈ $1076.67

Therefore;

The amount the student needs to save = $1076.67 - $807.5 = [tex]\$ \ 269\frac{1}{6}[/tex]

The amount the student needs to save ≈ $269.167.

Which of the following statements best describes the philosophy of the Progressives? rest represent silence in music which is a quarter rest Finding Your evidenceCan parents go too far in supporting their childrens dreams? This is a questionpeople sometimes ask when they hear the story of the teenage mountain climber,Jordan Romero. Between the ages of 10 and 15, Jordan climbed the highest mountainon every continentand his father and stepmother climbed them with him. They callthemselves Team Jordan.Paul Romero, Jordans father, was taken by surprise when his 9-year-old sonfirmly announced his intention to climb the seven summits. Jordan had seen a mural atschool, showing the seven peaks that make up this pantheon of mountains. When hetold his father what he wanted to do, Paul Romeros jaw dropped. Paul Romero is anexperienced mountaineer, so he knew what was involved. He also knew his son.Weve always taught him to just think big and well try to make it happen, PaulRomero said. But, as Romero later noted, there was a fine line between encouraginghis son and pushing him too far. The father began by training his son so that he couldbegin to even understand what mountaineering wasthat theres this long, hard, dirty,un-fun hours and days and weeks of carrying packs and long, extensive, brutal travel,and all this type of stuff just before you can even think of climbing a mountain.Jordan persevered, though, and in July 2006, when he was 10 years old, Jordanand his family climbed 19,300-foot-high Mount Kilimanjaro, the highest peak on theAfrican continent. This was the first rung in the amazing ladder that Jordan Romero hadset out to climb. Over the next five and a half years, Team Jordan climbed Mount Elbrusin Russia (2007), Mount Aconcagua in South America (2007), Mount McKinley in NorthAmerica (2008), Mount Carstensz Pyramid in Indonesia (2009), Mount Everest in Asia(2010), and Vinson Massif in Antarctica (2011). In many of these climbs, Jordan set aworld record as the youngest ever to climb the peak. When he completed the sevensummits at 15, he was the youngest person ever to accomplish that feat.It was the Mount Everest ascentwhen Jordan was only 13 years oldthat hascreated the greatest controversy. Jordans feat as the youngest person to reach thetop of the world was publicized around the world. How Young Is Too Young? askedone newspaper headline. Many mountain climbers and medical experts questionedwhether a 13-year-old boy could climb so high (Mount Everest is almost 30,000 feethigh) without physically harming his body. Dr. Michael Bradley, a psychologist andexpert on teen behavior, noted, Most 13-year-olds dont have the wiring to makecognitive life-and-death decisions and are not truly able to understand what theyresigning on for. Another physician, Dr. Peter Hackett, reported that there are conflictingopinions about the effects on a young brain. Some theories say that a young brain ismore resilient; others say that it may be more vulnerable.Many climbers take exception to the publicity surrounding Team Jordan. Everestclimber Todd Burleson summed it up by saying, Hes got his whole life to climbEverest. Being the youngest boy to climb is a fashionable, celebrity-oriented sort ofthing. But its not about the mountains. Its like trying to get your PhD at ten. PaulRomero claims that he is fully aware of the risks. There is a fine line betweenencouraging Jordan and pushing him too far, he says. He talked about the point whereJordan might have reached his maximum mentally, physically, and where the risk hasbecome too high. He said, Jordan has just not even come close to that point yet.And what about Jordan, now that he has accomplished his goal of climbing theseven summits before his 16th birthday? Unsurprisingly, he has a new mission. He callsit Find Your Everest. In 2012 Team Jordan set out to encourage young people to beactive and healthy and to pursue their own adventures. In the process, he is invitingyoung people to join him in climbing the highest peak in each state. (They range fromDenali or Mount McKinley at 20,320 feet to Floridas greatest height345-foot-highBritton Hill!)I feel good about what my parents have taught me about setting goals, Jordansays.
