The _______ pair is the location of a point on the coordinate plane and contains the
x coordinate and y coordinate

Answers

Answer:

Ordered

Step-by-step explanation:

The ordered pair is the location of a point on the coordinate plane and contains the x coordinate and y coordinate

An ordered pair tells you the location of a point by relating the point's location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair). In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate.

A, C , F, G, H are the five factors

220, 550, 440, 330, 100 are the  five numbers that have 2, 5, and 11 as prime factors. Hence, options (A), (B), (E), (F), (G) are correct.

What is prime factor?

Prime factor is a constituent that is a prime number, in other words, any prime number that can be multiplied to get the original number.

Example: The first two components of 15 are three and five.

The given numbers can be written as:

the prime factor of 220 = 2 × 2 × 5 × 11

the prime factor of  550 = 5  × 2 × 5 × 11

the prime factor of 190 = 2 ×5 × 19

the prime factor of 1045 = 5 × 11 × 19

the prime factor of  330 = 3 × 2 × 5 × 11

the prime factor of 110 = 2 × 5 × 11

Hence, 220, 550, 440, 330, 100 are the  five numbers that have 2, 5, and 11 as prime factors.

In a group of 20 students, 1 studies both Art and Biology.
1 studies Biology but not Art.
7 study neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?

Answers

Answer:

1/12

Step-by-step explanation:

Total number is 20.

Distribution is:

Art + Biology = 1Biology = 1Neither = 7

The rest = 20 - 9 = 11, the Art students

Total number of Art students becomes 12

The probability would be then:

Angle 3:

Angle 4:

Angle 5:

Angle 6:

Angle 7:

Angle 8:

Answers

Answer/Step-by-step explanation:

Given:

m<6 = 40°

Required:

Measure of all the other numbered angles

Solution:

Since line a is parallel to line b, therefore:

✔️m<1 = 180° - m<6 (supplementary angles)

m<1 = 180° - 40° (substitution)

m<1 = 140°

✔️m<2 = m<6 (corresponding angles)

m<2 = 40° (substitution)

m<3 = 180° - m<6 (same side interior angles are supplementary)

m<3 = 180° - 40° (substitution)

m<3 = 140°

✔️m<4 = m<6 (alternate interior angle)

m<4 = 40°

✔️m<5 = 180° - m<6 (linear pair)

m<5 = 180° - 40°

m<5 = 140°

✔️m<7 = m<5 (vertical angles)

m<7 = 140°

✔️m<8 = m<6 (vertical angles)

m<8 = 40°

At a local ballpark a team charges $10 per ticket the team must pay its players $4000 it costs the owner $6 for each souvenir they gave away how many tickets must be sold to break even

Answers

Answer:400

Step-by-step explanation:it didn’t say it gives away and souvenirs so the 6$ can be out the equation and 4000 divided by 10 is 400

The number of tickets that must be sold to break even is 1000 if at a local ballpark a team charges $10 per ticket the team must pay its players $4000.

What is linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is:

At a local ballpark, a team charges $10 per ticket. The team must pay its players $4000. It costs the owners $6 for each souvenir they give away.

How many tickets must be sold to break even.

Let x be the number of tickets.

Let y be the total cost

From the data given in the question we can frame the linear equation in two variables:

y = 6x + 4000

y = 10x

After solving the above two linear equations in two variables.

6x + 4000 = 10x

10x - 6x = 4000

4x = 4000

x = 1000

Thus, the number of tickets that must be sold to break even is 1000 if at a local ballpark a team charges $10 per ticket the team must pay its players $4000.

Answers

Answer:

a.0       b. 33.5

Step-by-step explanation:

absolute value means everything turns positive.

5-6=-1 +1=0

b. 2(16.75)= 33.5.

everything inside the bracket turns positive.

For part A
|5-6+1|

You either calculate the sum or difference to this equation and would turn out to be 0 as your answer

|5-6+1|=0

Therefore 0 is the answer to |5-6+1| for part A

For part B
2|-16.75|
The absolute value of any number is always positive

2*16.75

You then multiply it and then come up with 33.5


Therefore 33.5 is the answer for 2|-16.75| in part B.

2|-16.75|

Need help ASAP with all 3 Do the heart serve as a artery to push blood around the body? Read the following passage carefully before you choose your answer.The following is an excerpt from an autobiography written in the third person by Henry Adams, a prominent Bostonian.The chief charm of New England was harshness of contrasts and extremes of sensibilitya cold that froze the blood, and a heat that boiled itso that the pleasure of hatingone's self if no better victim offeredwas not its rarest amusement; but the charm was a true and natural child of the soil, not a cultivated weed of the ancients. The violence of the contrast was real and made the strongest motive of education. The double exterior nature gave life its relative values. Winter and summer, cold and heat, town and country, force and freedom, marked two modes of life and thought, balanced like lobes of the brain. (5)Town was winter confinement, school, rule, discipline; straight, gloomy streets, piled with six feet of snow in the middle; frosts that made the snow sing under wheels or runners; thaws when the streets became dangerous to cross; society of uncles, aunts, and cousins who expected children to behave themselves, and who were not always gratified; above all else, winter represented the desire to escape and go free. Town was restraint, law, unity. Country, only seven miles away, was liberty, diversity, outlawry, the endless delight of mere sense impressions given by nature for nothing, and breathed by boys without knowing it.Boys are wild animals, rich in the treasures of sense, but the New England boy had a wider range of emotions than boys of more equable climates. He felt his nature crudely, as it was meant. (10)To the boy Henry Adams, summer was drunken. Among senses, smell was the strongestsmell of hot pine-woods and sweet-fern in the scorching summer noon; of new-mown hay; of ploughed earth; of box hedges; of peaches, lilacs, syringas1; of stables, barns, cow-yards; of salt water and low tide on the marshes; nothing came amiss. Next to smell came taste, and the children knew the taste of everything they saw or touched, from pennyroyal and flagroot2 to the shell of a pignut and the letters of a spelling-bookthe taste of A-B, AB, suddenly revived on the boy's tongue sixty years afterwards. Light, line, and color as sensual pleasures, came later and were as crude as the rest. The New England light is glare, and the atmosphere harshens color. (15)The boy was a full man before he ever knew what was meant by atmosphere; his idea of pleasure in light was the blaze of a New England sun. His idea of color was a peony, with the dew of early morning on its petals. The intense blue of the sea, as he saw it a mile or two away, from the Quincy hills; the cumuli3 in a June afternoon sky; the strong reds and greens and purples of colored prints and children's picture-books, as the American colors then ran; these were ideals. The opposites or antipathies, were the cold grays of November evenings, and the thick, muddy thaws of Boston winter. With such standards, the Bostonian could not but develop a double nature. (20)Life was a double thing. After a January blizzard, the boy who could look with pleasure into the violent snow-glare of the cold white sunshine, with its intense light and shade, scarcely knew what was meant by tone. He could reach it only by education.Winter and summer, then, were two hostile lives, and bred two separate natures. Winter was always the effort to live; summer was tropical license.(1918)1Syringas are ornamental shrubs.2Pennyroyal is a mint plant; flagroot is the root of a particular herb.3Cumuli are thick clouds.In context, the word "drunken" (sentence 10) is best understood to mean (2 points)excitingconfiningconsumedfrighteningstupor-inducing
