Answer:

5.667 yards of fabric was used to make a cape

Step-by-step explanation:

(Total Yard of Fabric)1/3 = (What's Used)

Total Yard Fabric = 17

What's Used = x

1 third = 1/3

(17)1/3 = x

x = 17/3 or about 5.667 yards of fabric used

Double Check:

5.667/17 = 0.3334 which is about 1/3

If you want to find how much he has left:

1 - 1/3 = 2/3

17(2/3) = x

x = 34/3 or about 11.333 yards of fabric left.

Double Check:

11.333/17 = 0.6666 which is about 2/3

Step-by-step explanation:  sin β = [tex]\frac{oposite }{hypotenuse}[/tex] ; cos β = [tex]\frac{Adjacent}{Hypotenuse}[/tex]

10) sin [tex]32^{0}[/tex] = [tex]\frac{x}{18}[/tex]

18 sin [tex]32^{0}[/tex] = x

18 (0.53) = x

x= 9.5 units

cos [tex]32^{0}[/tex] = [tex]\frac{y}{18}[/tex]

18 cos [tex]32^{0}[/tex] = y

y = 18 (0.85)

in Mike’s house are broken now. His father replaced 3/14 of the broken) .4 windows. Uncle Jack replaced 1/7 of the broken windows. Who replaced the greater fraction of the broken windows?

Answers

Answer:

Mike's father produces a greater fraction.

Step-by-step explanation:

Amount of windows replaced by Mike's father = 3/14

Amount of windows replaced by Uncle Jack = 1/7

This 1/7 can also be expressed as 2/14

Now, since they both have the same denominators, it means that the higher the numerator the greater than the other fraction.

Thus, 3/14 is greater than 2/14.

Hence, Mike's father replaced a greater fraction of the broken windows.

factorise 49m²-84mn+36n² using the identity x²+(a+b)x+ab=(x+a)(x+b)​

Answers

Answer:

(7m-6n)(7m-6n)

Step-by-step explanation:

Given the expression 49m²-84mn+36n², this can also be written as;

49m²-84mn+36n²

= 7²m² - 84mn + 6²n²

= (7m)²-2*7m*6n+ (6n)²

= (7m-6n)²

= (7m-6n)(7m-6n)

Hence the expanded form is  (7m-6n)(7m-6n)

Where was his tea, he wondered? He looked around to see whether the servants were arriving with the longed-for cup of steaming liquid. Dipping his fingers languidly into the cool pond, he delicately plucked out an oval-shaped purple leaf with fine-toothed edges, then let it drop so he could capture a newer one, a larger, brilliantly red leaf whose crinkled surface curled like the palm of a hand. Behind him, at the edge of the wide, sloping lawn, the tall, green fronds of bamboo waved, as mild as grazing sheep, and the politely clicking melody of wooden wind chimes wafted from the weathered pine balcony of his twelve-bedroom cottage. He would write a poem, he decided, for the leaf-watching festival, the Emperors favorite week of the year. A poem, perhaps about the bare slopes of Mount Atu, and a lone climber struggling up the mountainside as a late spring snow began to cover his shoulders. I am that climber, he thought, remembering the recent power struggles at the palace.All the nobles and royals of the court would be present at the poetry reading contest, returning from their summer retreats to begin the excitement of the new social season. Cranes would fly picturesquely across the face of the full moon; toy paper boats carrying small-flamed candles would drift like glad-eyed children on the palaces artificial lake. Sighing with expectation, the prince inhaled deeply the thin, tickling tang of pine-needle incense. Yes, the Emperor would approve of his poem, and perhaps grant him an honor such as the green sash of the Keeper of the Park! Our civilization, the prince thought, has reached a glorious peak.How does this passage convey a sense of the time during which the scene occurs?It specifies that the poem will be about a late spring snow.It mentions a full moon, cranes, and toy boats floating on a stream.It shows the prince's thoughts about certain events.It describes objects in nature that indicate the season. ***98 POINTS *** someone please help Dario is finding the percent of change from the original price of $75 to new price of $125. what is the range of possible sizes for x?
