Answers

The height of the tree is 5.7m

What is angled of elevation?

Angle of elevation is the angle between the horizontal line and the line  of sight.

Analysis:

The height of the tree and the tree's shadow form a right angle triangle with the line of sight.

let the height of tree be h

tan 50 = h/4.8

h = 4.8 x tan 50

h = 4.8 x 1.191 = 5.7m

In conclusion, the height of the tree is 5.7m

Emma bought 2kg of fruit. 25% of the weight was pineapple. 10% of the weight was bananas. The rest was apples. How many grams of apples than bananas did emma buy?

Answers

Answer:

1.1kg

Step-by-step explanation:

weight of fruit = 2kg

percentage of weight of fruit = 100%

percentage of weight of pineapple = 25%

weight of pineapple = 25/100 ×2

= 0.5kg

percentage of weight of bananas = 10%

weight of bananas = 10/100 × 2

= 0.2kg

weight of apples = weight of fruit - ( weight of pineapple + weight of bananas)

= 2kg -(0.5 + 0.2)kg

= 2kg -0.7kg

= 1.3kg

The weight of apples than bananas emma bought was =1.3kg-0.2kg

=1.1kg

therefore emma bought 1.1kg of apples than bananas.

What fraction of 250 gallons is 144 L? Give your answer in simplest form. 1 gallon = 45L.
HELP URGENT FUE IN 10 mins

Answers

Answer:

0.0128

Step-by-step explanation:

Given that: 1 gallon = 45 L

Then,

x gallons = 144 L

So that,

x gallons = [tex]\frac{144}{45}[/tex]

               = 3.2

i.e 3.2 gallons = 144 L.

The fraction of 250 gallons that is 144 L can be determined as;

The fraction = [tex]\frac{3.2}{250}[/tex]

                    = [tex]\frac{8}{625}[/tex]

                    = 0.0128

The fraction of 250 gallons that is 144 L is 0.0128.

Check: 250 gallons = 250 x 45

                                 = 11250 L

Fraction required = [tex]\frac{144}{11250}[/tex]

                             = 0.0128

Scattered groups were hurrying from the direction of Woking, and one or two persons were returning. The crowd about the pit had increased, and stood out black against the lemon yellow of the skya couple of hundred people, perhaps. There were raised voices, and some sort of struggle appeared to be going on about the pit. Strange imaginings passed through my mind. As I drew nearer I heard Stent's voice:Keep back! Keep back!A boy came running towards me.It's a-movin', he said to me as he passed; a-screwin' and a-screwin' out. I don't like it. I'm a-goin' 'ome, I am.I went on to the crowd. There were really, I should think, two or three hundred people elbowing and jostling one another, the one or two ladies there being by no means the least active.He's fallen in the pit! cried some one.Keep back! said several.The crowd swayed a little, and I elbowed my way through. Every one seemed greatly excited. I heard a peculiar humming sound from the pit.I say! said Ogilvy; help keep these idiots back. We don't know what's in the confounded thing, you know!I saw a young man, a shop assistant in Woking I believe he was, standing on the cylinder and trying to scramble out of the hole again. The crowd had pushed him in.The end of the cylinder was being screwed out from within. Nearly two feet of shining screw projected. Somebody blundered against me, and I narrowly missed being pitched onto the top of the screw. I turned, and as I did so the screw must have come out, for the lid of the cylinder fell upon the gravel with a ringing concussion. I stuck my elbow into the person behind me, and turned my head towards the Thing again. For a moment that circular cavity seemed perfectly black. I had the sunset in my eyes.I think everyone expected to see a man emergepossibly something a little unlike us terrestrial men, but in all essentials a man. I know I did. But, looking, I presently saw something stirring within the shadow: greyish billowy movements, one above another, and then two luminous diskslike eyes. Then something resembling a little grey snake, about the thickness of a walking stick, coiled up out of the writhing middle, and wriggled in the air towards meand then another.A sudden chill came over me. There was a loud shriek from a woman behind. I half turned, keeping my eyes fixed upon the cylinder still, from which other tentacles were now projecting, and began pushing my way back from the edge of the pit. I saw astonishment giving place to horror on the faces of the people about me. I heard inarticulate exclamations on all sides. There was a general movement backwards. I saw the shopman struggling still on the edge of the pit. I found myself alone, and saw the people on the other side of the pit running off, Stent among them. I looked again at the cylinder, and ungovernable terror gripped me. I stood petrified and staring.A big greyish rounded bulk, the size, perhaps, of a bear, was rising slowly and painfully out of the cylinder. As it bulged up and caught the light, it glistened like wet leather.

Einstein's idea of gravity had big consequences. It helped explain some observations that Newton's idea didn't account for. It also opened our minds to amazing new possibilities. For example, taking his cue from Einstein's idea that space bends, scientist Karl Schwarzschild began to think about what would happen if a place in space were extremely distorted. His answer: light would follow the hyper-bent space, never to turn away from it. This was the first prediction of a black hole. At first, some scientists (including Einstein!) rejected Schwarzschild's ideas. Others were intrigued and began searching the skies for real black holes. Just decades later, they found the first of them. It just goes to show: sometimes, as Einstein himself once said, "Imagination is more important than knowledge." O Einstein's was a more enlightened thinker than Isaac Newton. O Einstein's ideas about gravity affected the way scientists viewed space. O Karl Schwarzschild could never have succeeded without Einstein's assistance. O Karl Schwarzschild's predictions were the most impressive scientific thinking in history.
