Milo drinks 2/5 of a bowls of water in 1/3 of an hour. How many hours will it take Milo to drink an entire bowl of water?

Answers

Answer:

It would take Milo 5/6 of an hour to drink an entire bowl of water.

Step-by-step explanation:

In this case, you can use a rule of three to find how many hours it will take to drink 1 bowl of water given that 2/5 of a bowl of water takes 1/3 of an hour:

2/5 of a bowl → 1/3 of an hour

1 bowl → x

x=(1*1/3)÷2/5

x=1/3÷2/5

x=(1*5)/(3*2)

x=5/6

According to this, the answer is that it would take Milo 5/6 of an hour to drink an entire bowl of water.

As she drove down the icy road, Mrs. Campbell slammed on her brakes. Her car did a 360. Explain what happened to Mrs. Campbell's car.

Answers

Answer:

Step-by-step explanation:

Her car doing a 360 means that the car turned in a manner akin to going round a full circle. This is because, she was moving on an icy way. Ice have been known to be slippery, and thus, stepping on the brakes unexpectedly would have made the car tilt a bit, which then increased to turning sideways, and an eventually full circle turning. This full circle turning is what is being referred to as 360

Mr Malloy wants to make sure amo and max get the best possible grade after five tests and can either give a grade based on the median or the mean

Answers

Answer:

• Median for Amo

• Mean for Max

Step-by-step explanation:

Amo's mean score:

= (97 + 92 + 89 + 55 + 90)/ 5

= 84.60

= 85

Max's mean score:

= (68 + 97 + 65 + 92 + 65) / 5

= 77

Amo's median:

First arrange the numbers in ascending order:

55, 89, 90, 92, 97

Median is middle which is 90.

Max's median:

65, 65, 68, 92, 97

Median is 68

Mr Javier should use Median for Amo and Mean for Max.

Answer:

Marta spent a total of $34.29

Step-by-step explanation:

Since she bought 3 towels for $8.50 each you would do 3 times $8.50 to get $25.50 for the towels and since she bought 5 washcloths for $1.25 each you would do 5 times $1.25 to get $6.25 then you would add the totals to get $31.75. Then you would find out the tax by finding out what 8% of $31.75 is which would be 2.54. So you would add $2.54 to $31.75 to get $34.29. So the total amount of money that Marta spent is $34.29

3 times $8.50 = $25.50

5 times $1.25 = $6.25

$25.50 + $6.25 = $31.75

BirchesBY ROBERT FROSTWhen I see birches bend to left and rightAcross the lines of straighter darker trees,I like to think some boy's been swinging them.But swinging doesn't bend them down to stayAs ice-storms do. Often you must have seen themLoaded with ice a sunny winter morningAfter a rain. They click upon themselvesAs the breeze rises, and turn many-coloredAs the stir cracks and crazes their enamel.Soon the sun's warmth makes them shed crystal shellsShattering and avalanching on the snow-crustSuch heaps of broken glass to sweep awayYou'd think the inner dome of heaven had fallen.They are dragged to the withered bracken by the load,And they seem not to break; though once they are bowedSo low for long, they never right themselves:You may see their trunks arching in the woodsYears afterwards, trailing their leaves on the groundLike girls on hands and knees that throw their hairBefore them over their heads to dry in the sun.But I was going to say when Truth broke inWith all her matter-of-fact about the ice-stormI should prefer to have some boy bend themAs he went out and in to fetch the cowsSome boy too far from town to learn baseball,Whose only play was what he found himself,Summer or winter, and could play alone.One by one he subdued his father's treesBy riding them down over and over againUntil he took the stiffness out of them,And not one but hung limp, not one was leftFor him to conquer. He learned all there wasTo learn about not launching out too soonAnd so not carrying the tree awayClear to the ground. He always kept his poiseTo the top branches, climbing carefullyWith the same pains you use to fill a cupUp to the brim, and even above the brim.Then he flung outward, feet first, with a swish,Kicking his way down through the air to the ground.So was I once myself a swinger of birches.And so I dream of going back to be.It's when I'm weary of considerations,And life is too much like a pathless woodWhere your face burns and tickles with the cobwebsBroken across it, and one eye is weepingFrom a twig's having lashed across it open.I'd like to get away from earth awhileAnd then come back to it and begin over.May no fate willfully misunderstand meAnd half grant what I wish and snatch me awayNot to return. Earth's the right place for love:I don't know where it's likely to go better.I'd like to go by climbing a birch tree,And climb black branches up a snow-white trunkToward heaven, till the tree could bear no more,But dipped its top and set me down again.That would be good both going and coming back.One could do worse than be a swinger of birches.1. What does the speaker want to think has caused the birches to bend? What really caused them to bend? Why might the speaker want to believe in the first cause?2. To what does the speaker compare the ice that falls from the birches? To what does he compare their trunks and leaves? What can you infer about the speaker's regarding the birches? What might the speaker mean when he say that "One could do worse than be a swinger of birches?3. In this poem, Frost compares life to a pathless wood.
