A) 628 meters
B) 251 meters
C) 126 meters
D) 63 meters

Answers

answer : c.) 126 meters

The solution is Option C.

The total distance skated by the ice skater is 126 meters

What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the centre for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

Given data ,

Let the distance traveled by the skater be = D

Let the diameter of the circle A be = 20m

Let the diameter of the circle B be = 20m

So , the radius of circle A = 10 m

The radius of circle B = 10 m

Now , the value of π = 3.14

So , the distance traveled by the skater = perimeter of circle A + perimeter of circle B

Perimeter of Circle A = 2πr

Substituting the values in the equation , we get

Perimeter of Circle A = 2 x 3.14 x 10

Perimeter of Circle A = 62.8 m

And ,

Perimeter of Circle B = 2πr

Perimeter of Circle B = 2 x 3.14 x 10

Perimeter of Circle B = 62.8 m

Therefore , the distance traveled by the skater = Perimeter of Circle A + Perimeter of Circle B

Substituting the values in the equation , we get

The distance traveled by the skater = 2 x 62.8

The distance traveled by the skater = 125.6 meters

The distance traveled by the skater = 126 meters

Therefore , the value of D is 126 meters

Hence , The total distance skated by the ice skater is 126 meters

Mr. Case is placing boxes along one of the walls in his attic. If the wall is 11 1⁄3 feet long and each box is 2 1/2 feet long, how many boxes can he fit along the

Answers

Answer:

4 8/15 boxes

Step-by-step explanation:

From the above question:

2 1/2 feet = 1 box

11 1/3 feet = x boxes

Cross Multiply

2 1/2 feet × x = 11 1/3 feet × 1 box

x boxes = 11 1/3 /2 1/2

x boxes = 34/3 ÷ 5/2

x = 34/3 ×2/5

x = 68/15

x = 4 8/15 boxes

Hence, he can fit 4 8/15 boxes

ANSWER: FG = 69

FG = FK + KG
KG = 1/2(FK)
FK = 46

RULE: When it comes to centroids, the longer section of the line is always 2/3 of the entire line (+ the shorter section of the line is always 1/3). This means that the shorter section of the line is HALF of the longer section of the line.

FG = FK + KG
FG = 46 + 46/2
FG = 46 + 23
FG = 69

CHECK:
FK = 2/3(FG)
46 = 2*69/3
46 = 138/3
46 = 46 ✔️

or

KG = 1/3(FG)
1/2(FK) = 1/3(FG)
46/2 = 69/3
23 = 23 ✔️

Which list shows the numbers in order from least value to greatest value

Answers

The answer is H

Explanation: what I did was change all of the numbers into decimal form so that we can compare them easier, -2 1/2= -2.5, -2.47 stays the same, -2/5 becomes positive .4 because the entire fraction is negative, you can look at it like -2/-5 and a negative divided by a negative is a positive, And then 5 stays a 5, And 21/4 equals 5.25 therefore your answer is H

Oh and by the way if you don’t know how to turn a fraction into a decimal you simply divide the top number by the bottom number for example 1/2 you take 1 and divide it by 2 which gives you .5 or 12/13 = .923076 hope this makes sense and that this helped

two angles are supplementary. the measure of the larger angle is 4 times more greater than the measure of the smaller angle what is the measure of the smaller angle

Answers

Answer:

36°

Step-by-step explanation:

Let the measure of the smaller angle be x and the larger angle be 4x.

Complementary angles add up to 180°.

Smaller angle + Bigger angle = 180°

x + 4x = 180°

5x = 180°

x = 180° ÷ 5

x = 36°

Smaller angle = 36°

Read the passage.Space Junk!Imagine small pieces of debris hurtling through space at up to 22,300 miles per hourfaster than a speeding bullet. Next, envision those pieces of debris colliding with each other, explosively creating even more smashed bits, as they continue zooming through space. Now, try to imagine a cloud of this debris encircling our planet.You have just created a picture of space junk.Space junk is a term used to describe the different bits and pieces of debris that orbit earth and other planets at mind-boggling speeds.What is this junk, and how did it end up in outer space?This junk is actually debris from objects sent into space. It includes everything from parts of space shuttles to satellites. Pieces from rocket launchers, bits of metal fallen off of satellites, nuts and bolts, and even chips of paint are all considered space junk. The Space Surveillance Network, a group that keeps track of the debris, has seen garbage bags, lens caps, and even a spatula!Currently, there are around 900,000 pieces of debris between 1 centimeter and 10 centimeters in length orbiting in our space system, and this number is growing. The pieces vary in size from softball-sized to those the size of marbles, or even smaller. Additionally, there are millions of debris pieces too small to measure.But isnt space HUGE? Isnt there enough room for these little bits of junk to pass each other?Although space is extremely vast, most of the junk that is worrisome is orbiting earth. It is estimated that there are about 22,300 bits of trash the size of golf balls, in addition to half a million smaller pieces whizzing around earth in the low earth orbit. This means that the junk is within 1,250 miles of earths surface. Sharing this space are active satellites, so there is growing concern about how to keep the satellites from being hit by the debris. There have been a few incidents where this has already happened. For example, in 1996, some debris from a French rocket damaged a French satellite. Surprisingly, the rocket had been launched ten years previously! In 2009, a non-operational Russian satellite smashed into an American satellite. This collision added another 2,000 pieces of junk to the growing pile of space debris.Scientists have labored for years to try to protect both active satellites and the International Space Station (ISS), a space laboratory run by astronauts from different nations. To protect the ISS, scientists have developed the capability to maneuver the station out of harms way. There are also emergency plans in place to protect the astronauts working at the ISS. These plans would isolate the crew to another part of the station to keep them safe in the event of a collision.Still, these measures do not solve the problem of what to do about space junk.In our modern world, we have become more and more dependent on satellites to help us with many things. Among these are communication systems, weather predictions, and navigation. The more we rely on advanced technology, the more likely it is that we will send additional satellites into space. It is not realistic to assume that the number of items launched into space will decrease.Scientists are working on solutions to deal with the problem. For example, Japan has designed a device that looks like a giant rope with a 444-pound weight attached to one end. The weight could swing around and basically knock debris out of orbit. Then it would burn up in earths atmosphere. Other ideas for debris removal have included harpoons, giant magnets, and nets that would capture the debris. Some solutions propose an end-of-life plan for future launches, in which the debris would be sent farther into space or destroyed.Because humans interest in exploring space continues to grow, there is little chance that the number of objects in space will decrease. However, as people become more aware of the problem of space junk, the same energy dedicated to exploring space must be directed toward creative ways of cleaning it up.Question 1Part AAccording to "Space Junk!," what will most likely happen to the amount of junk in space?The amount will fluctuate. The amount will grow. It will stay the same.It will decrease over time.Question 2Part BWhich evidence from the text best supports the answer to Part A?"Still, these measures do not solve the problem of what to do about space junk. ""The more we rely on advanced technology, the more likely it is that we will send additional satellites into space.""In our modern world, we have become more and more dependent on satellites to help us with many things.""The weight could swing around and basically knock debris out of orbit."
