Arwa is playing 'Guess my number'. Arwa says: 'If I add 0.4 to my number, divide the answer by 8, then multiply that answer by 9, I get 0.9.' What is Arwa's number?

Answers

0.4 is the answer because you if you work backwards and use inverse operations you get 0.4.
meaning, if you divide 0.9 by 9, you get 0.1. when you multiply 0.1 and 8 you get 0.8. and when you subtract 0.4 from 0.8 you get your answer, 0.4.

The semicircle below has a diameter of 20. Find the area of the blue region.

Answers

Answer:

61

Step-by-step explanation:

Use the area of semicircle minus the area of the triangle. Area of the semicircle is 10^2 * pi / 2 = 50 pi, the area of the triangle is 12*16/ 2 = 96. The the area for the blue part is 50 pi - 96 = 61.07963268 or 61.

If it is helpful, plz give me Brainliest.

Answer:

50pi - 96

Step-by-step explanation:

The radius of the semicircle is 10, so the area of the entire semicircle is 1.2*10^2 pi = 50pi

The white triangle has an area of 1/2*12*16 = 96 so subtracting it shows that the blue area is 50pi-96

Please please find the area for this polygon!

Answers

Answer:

508

Step-by-step explanation:

28*16= 448

6*6= 36

4*6= 24

448+36+24= 508

In order to find the area of a polygon, all you have to do is follow the formula: area = 1/2 x perimeter c apothem. To sum it together, perimeter = the sum of the lengths of all the sides. So add 6, 16, 16, 6, 4, 6, 28, and 18! And then you have 100! Then multiply it by 1/2! So your answer should be 50. Please consider brainliest.

A $20 $???

B $??? $14

C $60 $???

D $??? $59

Answers

Answer:

See missing answers bold

$20 original = $5 final paid           as $15 was s/p before -10 was added

$30 original = $14 final price        as $24 was s/p before -10 was added

$60 original = $35  final price    as $45 was s/p before -10 was added

$92 original  = $69 final price       as $59  was s/p before -10 was added  

Step-by-step explanation:

Ans in bold  

A) = f(x) = 20(0.75) -10 =  15 - 10  = $5                 = £5 final paid

B)= f(x)  30 (0.75) = 24 - 10 = 14                           = $30 original price

C)  = f(x) = 60(0.75) -10 = 45 -10 = $35               = $35 final price

D)     = f(x) = 92 (75) = 69 -10 = $59                    = $92 original price

Answer: for the first one it is 22 percent

Step-by-step explanation: first I found out that 14.08 is In-between 64 and 78.08 . Then I devided 14.08 by 64 so I got 0.22 then i made that a percentage by multiplying it by 10. So the answer is 22 percent. Please mark me brainiest.

Answer:

65°

Step-by-step explanation:

the angle of a straight line has to add up to 180°

if it doesn't, it's not a straight line

115° and x are supplementary angles

meaning we know they have to add up to 180°

so simply subtract

180- 115 =

65°

you can check work by adding

115+65= 180

Answer: 65

180-115=65

Step-by-step explanation:

A straight line is always 180 so I subtracted 115 from 180.

When Gregor Samsa woke up one morning from unsettling dreams, he found himself changed in his bed into a monstrous vermin. He was lying on his back as hard as armor plate, and when he lifted his head a little, he saw his vaulted brown belly, sectioned by arch-shaped ribs, to whose dome the cover, about to slide off completely, could barely cling. His many legs, pitifully thin compared with the size of the rest of him, were waving helplessly before his eyes.Whats happened to me? he thought. It was no dream. His room, a regular human room, only a little on the small side, lay quiet between the four familiar walls. Over the table, on which an unpacked line of fabric samples was all spread out--Samsa was a traveling salesman--hung the picture which he had recently cut out of a glossy magazine and lodged in a pretty gilt frame. It showed a lady done up in a fur hat and a fur boa, sitting upright and raising up against the viewer a heavy fur muff in which her whole forearm had disappeared.Gregors eyes then turned to the window, and the overcast weather--he could hear raindrops hitting against the metal window ledge--completely depressed him. How about going back to sleep for a few minutes and forgetting all this nonsense, he thought, but that was completely impracticable since he was used to sleeping on his right side and in his present state could not get into that position. No matter how hard he threw himself onto his right side, he always rocked onto his back again. He must have tried it a hundred times, closing his eyes so as not to have to see his squirming legs, and stopped only when he began to feel a slight, dull pain in his side, which he had never felt before.Evaluate the excerpt from Metamorphosis.
