Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?

Answers

Answer:

2/3

Step-by-step explanation:

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?

1 decametre = 10 metres

Hence,

10 meters = 6 pieces of ribbon

1 meter = x pieces

Cross Multiply

10x = 6

x = 6/10

x = 2/3 (1 meter pieces of ribbon)

When doing decimals, what does a dot over a number mean? For example, take 24.671, but theres a small dot over the numbers 6 and 1. What do I do and what does it mean?

Answers

Step-by-step explanation:

The dot is called a decimal point. It is also called the decimal separator. It separates whole numbers from fractional numbers.

In this example;

24.671

The numbers before the point, 24 is the whole number

The numbers after the point, 671 are the fractional portion of the number. They represent 6 tenths, 7 hundredths and 1 thousandths.

Also, the number of digits after the point tells you how many decimal place the number is in. In this example the number of decimal places is 3.

Step-by-step explanation:

Hope this helps! :)

Answer:

1. 8x + 3y - x - 2y

= 8x - x + 3y - 2y

= 7x + y

2. 3n - 7n - 2n + x + 8x

= 3n - 9n + 9x

= - 6n + 9x

3. 2r - 5n + 9y - 3r + n

= 2r - 3r - 5n + n + 9y

= -r - 4n + 9y

4. 12y - 6x + 5y - 3n

= 12y + 5y - 6x - 3n

= 17y - 9n

5. - 13n + 4n - r

= -9n - r

6. 7xy - 8x + 6xy - y

= 7xy + 6xy - 8x - y

= 13xy - 8x - y

7. - 14r - 10n - 3r - 9n

= -14r - 3r - 10n - 9n

= - 17r - 19n

8. 6r + 9r - 2r - 13n

= 6r + 7r - 13n

= 13r - 13n

9. n + r + x - 3x +4r

= n + r + 4r + x - 3x

= n + 5r - 2x

10. 15y - 7x + 9z + 4z - 3x

= 15y - 7x - 3x + 9z + 4z

= 15y - 10x + 13z

What is the area, in square meters, of the shaded region in the diagram?

Answers

Answer:

Notice that the side length of the square is  38 m.

area of square  =  (side length)2  =  (38 m)2   =   1444 m2

Notice that the diameter of the circle is  38 m .

And its radius  =  diameter / 2   =   38m / 2   =   19 m

area of circle  =  pi * radius2  =  pi * (19m)2  =  pi * 361 m2   ≈   1133.54 m2

So......

area of shaded region  =  area of square - area of circle

area of shaded region  ≈       1444 m2     -  1133.54 m2

area of shaded region  ≈    310.46 m2

Step-by-step explanation:

Notice that the side length of the square is  38 m.

area of square  =  (side length)2  =  (38 m)2   =   1444 m2

DOES THIS LOOK GODD??The people of ZincWritten by: Ava.NCharacters by: Ava. NOne of the most desolate days of Zincs was in 2000 on Friday, Jan 1. It was a new years day, everybody was having fun, running around playing, and singing. The Zinc always invited people that came into their village. The people of Zink were the nicest and smartest of the village. They didn't even know what was going to happen next when they invited Zandar. Zandar the ruler of kings. He wore a black robe, and went straight to the church on Friday, Jan 1. I was there. I knew what he looked liked and I didnt like him at first. Napkin followed him to the church, trying to stay behind him but not too close but not too far. He took off his robe, then some weird muscler cats came out of nowhere. Man those are some big cats, I wonder if they're just here to worship their gods or something. Napkin whispered. Is the ship here yet? Zandar mumbled Yes my king. The minion bowed his head in approval, to the king. A starved cat wobbled up the stairs with bloat pink eyes. My king may you spare us some food. The starving swollen cat whimpered. My people are bringing some food right now and it's filled with crates of bread and fish. Tell all your friends to come over and get some bread and fish. The more friends you bring the more bread and fish you get. Zandar said in a happy tone. Yes my lord! I shall hurry off and get all my family and friends. The starving cat, not looking starving anymore, ran off behind an open alley. I can see the crates from here, you may go get more cats. Zandar hesitated. For our feast.A few minutes later, a large number of boxes, and crates were everywhere around the church. It never smelled like fish or bread anywhere, it was mostly smelled like powder. Napkin snuck behind the church getting to one of the boxes. The smells stinged his nose, making him almost sneeze. He tried all his strength to open one of the boxes. AHH! Napkin screamed. What was that! Zandar whispered, biting his lip hard. Almost making it bleed. Probably just some kids chasing each other. One of the minions said.Napkin ran in front of the church, almost rolling over on his back.HE HAS GUNS! Napkin screamed.It felt like the whole village turned quiet for one second. Zandar let his claws out, gripping them to the church, almost breaking the stone cobbla. His eyes were furious. Africa ran to bite his brother on the neck grabbing his scruff. Sorry for my little brother, he just had too much milk today! Africa apologized I'm telling the truth! Please listen to me! You'll all die! Napkin was trying to struggle to get out of his brothers grip. Zandar smiled evilly at Napkin, being pulled away by his brother. Napkin could not hear what Zandar was saying to his Minions but...Happy New year! Zandar laughed.The pulling of Napkins brother stopped. Napkin ran as fast as he could, seeing bodys drop left and right of him. Hearing bullet guns drop. He stopped running pushing the dirt and gravel in the air, running back to his brother.No! Napkin yelled. Pushing his head against the dead body of his brother. He felt pain in his head and in his stomach. Zandar punched on Napkin. He rolled over hitting the gravel upside down making his nose bleed. Zander's hand unleashed his long claws in the air. Swinging down, if flet slow in Napkins brain. He rolled over and ran as fast as he could. Getting from under Zandar.Everyone I know is dead, everyone I talked to is dead, EVERYONE.. Napkin thought in his head tears rolling down from his eyes running away from the church. Anywhere away from him, ANYWHERE!Chapter 1: The Invitation Napkin sprinted from the bushes chasing the rabbit. Sweat came down from his fur trying not to lose the rabbit. Mouse brain! Napkin yelled. A hawk had grabbed the rabbit with their sharp talons, flying off into the distance. Dang it. Napkin kicked dirt across the grass. That's the third one today! I'm going to start to get dizzy at some point in the day. Napkin walked to the right bank of a river, drinking some water. Got to stay hydrated I guess? Napkin felt a pain in his left shoulder, he fell back on his stomach, looking near the left of his eye seeing blood flow down his left shoulder. He stood shaking in pain as he looked up, seeing a black figure approaching him out of the blushes, walking towards him in the river. He couldn't keep his eyes open any longer, his eyelids got heavier and heavier. 8.What type of biographer/subject relationship does the following passage represent?Throughout her career, Beverly Cleary has won many awards for her writing, including the 1975 Laura Ingalls Wilder Award and the Newbery Medal in 1984 for Dear Mr. Henshaw.A. autobiographyB. firsthand biographyC. biographer did not personally know the subject Please help me I will give you the brain thing and extra points please it's for ELA please help me, I can make the points double? 2And this was the reason that, long ago, In this kingdom by the sea,A wind blew out of a cloud, chilling My beautiful Annabel Lee;So that her highborn kinsmen came And bore her away from me,To shut her up in a sepulchre In this kingdom by the sea.Which word best describes the MOOD of the passage?Question 2 options:A.joyfulB.confusedC.relaxedD.sorrowful Which organelle is like the brain of the cell? vacuole O endoplasmic reticulum O cytoplasm O nucleus (03.02 MC)Rachel needs a car to get to work and school.
