3 There are 5 times as many boys as girls in a school.
Together the school has 810 pupils.
How many boys are there?

Answers

Answer:

Number of boys = 675

Step-by-step explanation:

Given that:

There are 5 times as many boys as girls in a school.

Number of pupils in school = 810

Let,

x be the number of girls

y be the number of boys

According to given statement;

x+y=810      Eqn 1

y = 5x         Eqn 2

Putting y=5x in the Eqn 1

x+5x=810

6x=810

Dividing both sides by 6

[tex]\frac{6x}{6}=\frac{810}{6}\\x=135[/tex]

Putting x=135 in Eqn 2

y = 5(135)

y = 675

Hence,

Number of boys = 675

y° = 70°

z° = 140°

8. y° and 70° are the measures of the angles subtended in the same arc. So, they would be equal.

Therefore, y° = 70°

Measure of central angle is two times the measure of the inscribed angle.

Step-by-step explanation:

Area of triangle equals to half of the base times height, i.e. A = 1/2 × b × h.

1/2 x 22 x 16 = 1/2 x 20 x BD

BD = (1/2 x 22 x 16) / (1/2 x 20)

the robots are powered on coffee alone. they use two bags of coffee each day.how long will 1/4 bag last?

Answers

Answer:

One robot will be powered for an eighth of a day (1/8 of a day) by one quarter (1/4) of a bag of coffee.

Answer: 3 hours

Explanation: There are 24 hours in a day, and the robots use 2 bags of coffee a day, so you gotta do 24/2 and that means 1 bag of coffee lasts 12 hours. Next, the question is how long does 1/4 bag last, so you do 12/4 and get 3, therefore the correct answer is 3 hours. Hope this helped!

Answers

Answer:

5.5

Step-by-step explanation:

Given the set of data

5, 4, 2, 1, 1, 2, 10, 2, 3, 5.

The average of the least and the greatest value is known as the midrange

The formula for calculating the midrange is expressed as shown:

Midrange = (Greatest value + Least value)/2

Given

Greatest value = 10

Least value = 1

Midrange = 10+1/2

Midrange = 11/2

Midrange = 5.5

Hence the midrange of the data is 5.5

5 1/4 - 2 5/7 = and fraction model NEGORE, THE COWARDHe had followed the trail of his fleeing people for eleven days, and his pursuit had been in itself a flight; for behind him he knew full well were the dreaded Russians, Negore fled after his fleeing tribe and came upon it this summer night by the head waters of the Pee-lat. Though near the midnight hour, it was bright day as he passed through the weary camp. Many saw him, all knew him, but few and cold were the greetings he received."Negore, the Coward," he heard Illiha, a young woman, laugh, and Sun-ne, his sister's daughter, laughed with her.Black anger ate at his heart; but he gave no sign, threading his way among the camp-fires until he came to one where sat an old man. A young woman was kneading with skillful fingers the tired muscles of his legs. He raised a sightless face and listened intently as Negore's foot crackled a dead twig."Who comes?" he queried in a thin, tremulous voice."Negore," said the young woman, scarcely looking up from her task.Negore's face was expressionless. For many minutes he stood and waited. The old man's head had sunk back upon his chest. The young woman pressed and prodded the wasted muscles, resting her body on her knees, her bowed head hidden as in a cloud by her black wealth of hair. Negore watched the supple body, bending at the hips as a lynx's body might bend, pliant as a young willow stalk, and, withal, strong as only youth is strong. He looked, and was aware of a great yearning, akin in sensation to physical hunger. At last he spoke, saying:"Is there no greeting for Negore, who has been long gone and has but now come back?""Thou art my woman, Oona," Negore said, his tones dominant and conveying a hint of menace.She arose with catlike ease and suddenness to her full height, her eyes flashing, her nostrils quivering like a deer's."I was thy woman to be, Negore, but thou art a coward; the daughter of Old Kinoos mates not with a coward!""Old Kinoos and I came among you from a strange land. Thy people took us in by their fires and made us warm, nor asked whence or why we wandered. It was their thought that Old Kinoos had lost the sight of his eyes from age; nor did Old Kinoos say otherwise, nor did I, his daughter. Old Kinoos is a brave man, but Old Kinoos was never a boaster. And now, when I tell thee of how his blindness came to be, thou wilt know, beyond question, that the daughter of Kinoos cannot mother the children of a coward such as thou art, Negore."Again she silenced the speech that rushed up to his tongue."Know, Negore, if journey be added unto journey of all thy journeyings through this land, thou wouldst not come to the unknown Sitka on the Great Salt Sea. In that place there be many Russian folk, and their rule is harsh. And from Sitka, Old Kinoos, who was Young Kinoos in those days, fled away with me, a babe in his arms, along the islands in the midst of the sea. My mother dead tells the tale of his wrong; a Russian, dead with a spear through breast and back, tells the tale of the vengeance of Kinoos."But wherever we fled, and however far we fled, always did we find the hated Russian folk. Kinoos was unafraid, but the sight of them was a hurt to his eyes; so we fled on and on, through the seas and years, till we came to the Great Fog Sea"At last we came to Pastolik, which is where the Yukon drowns itself in the Great Fog Sea."So, when there came a ship, Old Kinoos stepped forward and said he would show the way. He was an old man then, and his hair was white; but he was unafraid. And he was cunning, for he took the ship to where the sea sucks in to the land and the waves beat white on the mountain called Romanoff. The sea sucked the ship in to where the waves beat white, and it ground upon the rocks and broke open its sides. Then came all the people of Pastolik, (for this was the plan), with their war-spears, and arrows, and some few guns. But first the Russians put out the eyes of Old Kinoos that he might never show the way again, and then they fought, where the waves beat white, with the people of Pastolik."Now the head-man of these Russians was Ivan. He it was, with his two thumbs, who drove out the eyes of Kinoos. He it was who fought his way through the white water, with two men left of all his men, and went away along the rim of the Great Fog Sea into the north. Kinoos was wise. He could see no more and was helpless as a child. So he fled away from the sea, up the great, strange Yukon, even to Nulato, and I fled with him."This was the deed my father did, Kinoos, an old man. But how did the young man, Negore?"What information in the story would best support the idea that Kinoos should be called Kinoos, the brave? (1 point)Select one:a. He entered many unknown villages seeking shelter.b. He raised a child on his own.c. He travelled across the Great Fog Sea.d. He volunteered for a dangerous deed.
