compare the expressions
3 X 10 and 15 x 20 without multiplying them. Explain how she
could compare the factors to compare the expressions without
multiplying them.

Answers

Answer 1

Answer:

yes

Step-by-step explanation:

Well 3 is a factor of 15, and 10 a factor of 20. So 15/3 is 5, and 20/10 is 2.

5*2 is 10, which means that 15*20 is 10 times greater than 3*10.

If you actually did multiply them, 15 by 20 is 300 and 3 by 10 is 30. It would logically be correct.

What is the slope of the line that is perpendicular to the line that passes through the points (-1,3) and (2,-4)?

Answers

Hey there! Remember that perpendicular lines are the negative reciprocal to the original slope. With that in mind, the best way to find the slope is by using equation m=y2-y1/x2-x1, so then if we plug this in we get:

-4-3/2-(-1)

As -4 is our y2, -3 is our y1, 2 is our x2, and -1 is our y1.

You should get -7/3, that’s the original slope. Since this is a perpendicular line we MUST FLIP it and CHANGE THE SIGN.

So our FINAL answer would be: 3/7

Unicorns love eating jelly beans! If a unicorn eats 410.7 ounces of jelly beans 6 times a day, how many ounces does it eat in one day?

Answers

Answer:

2464.2

Step-by-step explanation:

you multiply 410.7 by 6 to get this

The ounces of jellybean eaten in a day is required.

The amount of jellybean the unicorns eats in one day will be 2464.2 ounces.

The ounces of jellybean eaten at one time is 410.7 ounces

The number of times jellybean is eaten during one day is 6 times.

[tex]1\ \text{time}=410.7\ \text{ounces}[/tex]

Answer:

y=1/2x - 2.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

We can use the point-slope formula to write an equation for this line. The point-slope formula states :

where m  is the slope and (x1   y1)  is a point the line passes through .

We can substitute the slope and values from the point to give:

(y-1) = 8 (x-7)

We can also transform this equation to the slope-intercept form by solving for  

y

. The slope-intercept form of a linear equation is: y=mx+b

where the m is the slope and b s the y-intercept value.

y-1= (8 times x) - ( 8 times 7)

y-1=   8x - 56

y-1 + 1= 8x- 56 + 1

y-0=  8x- 55

y= 8x - 55

∠ FCE and ∠ C are vertically opposite angles and are congruent , then

∠ C = 150°

∠ FCE and ∠ ECB are adjacent angles on a straight line and sum to 180°

∠ ECB = 180° - ∠FCE = 180° - 150° = 30°

∠ E = 180° - (30 + 45)° ← sum of angles in a triangle

∠ E = 180° - 75° = 105°

The basketball team scored 49 points in thechampionship game. This is 12 points more than
half of their score in the first round game. How many points did the team score in their first round game?

Answers

49 - 12 = 35
35 * 2 = 70

They scored 70 points in their first round game.

You start with the Championship Game score. This score is 12 points MORE than Half of the first round games score. So if you subtract 12 from the 49 points they got in the championship game then you would get 35 which is half of the first round games score.

Since 35 is half the score, if you multiply 35 by 2 you would get the total First Round Game score of 70.

the slope of a line is the ratio y/x.

that means when going from one point to the other, how many units is y changing, when x changes a certain number of units.

so, going from one point to the other here, x changes by 30 units (from -12 to +18). and y changes 15 units (from -9 to 6).

therefore, the slope is

Step-by-step explanation:

We actually don't care what amount of paper is white, we just need the amount per truck. If there were 2 trucks, they would each take half of the total amount of paper. If there were 3 trucks, they would each take a third of the total amount of paper. And so on for 4,5,6,etc.

For 28 trucks, they would each take a twenty-eighth of the total amount of paper. So, the amount each truck takes is just [tex]952/28=34[/tex].

considering the line negative x -6 y equals -6 what is the line perpendicular with a slope of a line perpendicular to this line what is the slope of the line parallel to this line​

Answers

9514 1404 393

Answer:

  perpendicular: undefined

  parallel: zero

Step-by-step explanation:

The line y = -6 is a horizontal line. Between any two points on the line, the difference in y-values is zero, and the difference in x-values is non-zero. The slope of this horizontal line is the ratio of these differences:

  slope = 0/(non-zero) = 0

Any parallel line will have the same slope. The slope of a parallel line is 0.

__

A line perpendicular to a horizontal line is a vertical line. It will have the equation x = constant. Between any two points on the line, the difference in y-values is non-zero, and the difference in x-values is zero. The slope of this vertical line is the ratio of these differences:

  slope = (non-zero)/0 = undefined

The slope of the perpendicular line is undefined.

Part A = 14 and Part B = 18 are numerators for each fraction.

The fractions are then:

Meaning:
Part A is 14/32 of the whole

An Excerpt from Optimismby Helen Keller1 Could we choose our environment, and were desire in human undertakings synonymous withendowment, all men would, I suppose, be optimists. Certainly most of us regard happiness asthe proper end of all earthly enterprise. The will to be happy animates alike the philosopher, theprince and the chimney-sweep. No matter how dull, or how mean, or how wise a man is, he feelsthat happiness is his indisputable right.2 It is curious to observe what different ideals of happiness people cherish, and in what singularplaces they look for this well-spring of their life. Many look for it in the hoarding of riches, somein the pride of power, and others in the achievements of art and literature; a few seek it in theexploration of their own minds, or in the search for knowledge.3 Most people measure their happiness in terms of physical pleasure and material possession.Could they win some visible goal which they have set on the horizon, how happy they would be!Lacking this gift or that circumstance, they would be miserable. If happiness is to be someasured, I who cannot hear or see have every reason to sit in a corner with folded hands andweep. If I am happy in spite of my deprivations, if my happiness is so deep that it is a faith, sothoughtful that it becomes a philosophy of life,if, in short, I am an optimist, my testimony tothe creed of optimism is worth hearing....4 Once I knew the depth where no hope was, and darkness lay on the face of all things. Thenlove came and set my soul free. Once I knew only darkness and stillness. Now I know hope andjoy. Once I fretted and beat myself against the wall that shut me in. Now I rejoice in theconsciousness that I can think, act and attain heaven. My life was without past or future; death,the pessimist would say, a consummation devoutly to be wished. But a little word from thefingers of another fell into my hand that clutched at emptiness, and my heart leaped to therapture of living. Night fled before the day of thought, and love and joy and hope came up in apassion of obedience to knowledge. Can anyone who has escaped such captivity, who has feltthe thrill and glory of freedom, be a pessimist?5 My early experience was thus a leap from bad to good. If I tried, I could not check themomentum of my first leap out of the dark; to move breast forward is a habit learned suddenlyat that first moment of release and rush into the light. With the first word I used intelligently, Ilearned to live, to think, to hope. Darkness cannot shut me in again. I have had a glimpse of theshore, and can now live by the hope of reaching it.6 So my optimism is no mild and unreasoning satisfaction. A poet once said I must be happybecause I did not see the bare, cold present, but lived in a beautiful dream. I do live in abeautiful dream; but that dream is the actual, the present,not cold, but warm; not bare, butfurnished with a thousand blessings.
