Answers

Answer:

= 1 . 8 4 6 1 5 3 8 4 6

Step-by-step explanation:

I took the test yesterday and I got a 100 on the math part

Answer/Step-by-step explanation:

Combine multiplied terms into a single fraction

2.7z+1.2z−6.5=0.7

2 7 / 1 0 + 1 . 2 − 6 . 5 = 0 . 7

Combine multiplied terms into a single fraction

2 7 / 1 0 + 1 . 2 − 6 . 5 = 0 . 7

2 7 /1 0 + 6 5 − 6 . 5= 0 . 7

Find common denominator

2 7 /1 0 + 6 5 − 6 . 5= 0 . 7

[tex]\frac{27z}{10} +\frac{2.6z}{10} +\frac{10(-6.5)}{10} =0.7[/tex]

Combine fractions with common denominator

[tex]\frac{27z+2*6z+10(-6.5)}{10} =0.7[/tex]

Multiply the numbers

[tex]\frac{27z+12z-65}{10} =0.7[/tex]

Combine like terms

[tex]\frac{39z-65}{10} =0.7[/tex]

Multiply all terms by the same value to eliminate fraction denominators

[tex]10*\frac{39z-65}{10} =10*0.7[/tex]

Cancel multiplied terms that are in the denominator

39z-65=10*0.7

Multiply the numbers

39z-65=7

Add 65 to both sides of the equation

39z-65+65=7+65

Simplify

39z=72

Divide both sides of the equation by the same term

[tex]\frac{39z}{39} =\frac{72}{39}[/tex]

What's the best first step in solving-4 + 2/5 > 5/10

Answers

Answer:

B

Step-by-step explanation:

There are 2 operations happening on the left side to x.

1. x is being multiplied by -4.

2. 2/5 is being added to -4x.

If you had a number for x, and you wanted to evaluate the left side, first, you would multiply the value of x by -4. Then you would add 2/5.

To solve an equation or an inequality, you do the opposite operation in the opposite order.

Since the second operation was add 2/5, to solve, you start by doing the opposite of the second operation. That means you subtract 2/5 from both sides.

Translate the following phrase into an inequality:


"A number n minus 3.5 is less than or equal to 4."

PLEASE HELP I HAVE 6 MATH MISSING ASSIGNMENTS, I HATE HIGH SCHOOL

Answers

Answer:

The term "at least" means the lowest number you can have. In other words, you cannot have a number less than that point. So we use the greater than or equal symbol.

x - 3 ≥ - 5

Add 3 on both sides of the inequality.

x ≥ -2

x is any number greater than or equal to -2.

If the term was "at most", then that is the highest number you can have, and you can go no higher than that. In this case, we would have used the less than or equal to symbol.

These terms are important to understand when working with inequalities.

The value of the inequality form of the phrase "A number n minus 3.5 is less than or equal to 4." is (n - 3.5) ≤ 4 .

Used the concept of inequality that states,

A relation by which we can compare two or more mathematical expressions is called an inequality.

Given that;

The phrase is,

"A number n minus 3.5 is less than or equal to 4."

Now it can be written in inequality form as,

(n - 3.5) ≤ 4

Therefore, the inequality is,

(n - 3.5) ≤ 4

What trig function and angle is equivalent to sin(270°)?

Answers

Answer:

θradians sin(θ)

3π/2 -1

Step-by-step explanation:

leave a thanks if helped pls <3

The trigonometric function gives the ratio of different sides of a right-angle triangle. The trigonometric function and angle are equivalent to sin(270°).

What are Trigonometric functions?

The trigonometric function gives the ratio of different sides of a right-angle triangle.

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

Given the trigonometric function sin(270°) which can be written in the form of radian angle. So that the value of the angle is the same. Therefore, the trigonometric function and angle that is equivalent to sin(270°) can be written as,

sin(270°) = sin(3π/2)  = -1

Also, if the trigonometric function is needed to be changed then we can write,

sin(3π/2) = cos(π) = cos(180°) = -1

Hence, the trigonometric function and angle are equivalent to sin(270°).

Work out m and c for the line: ? y = x + 6​

Answers

Well your c value is already there (6) as the standard equation for a line is
y = mx + c

To find the gradient (M) plot two points on the line.

Then label each co ordinate X1 and X2 and then Y1 and Y2

Then subtract your y1 from y2 and then x1 from x2.

For example :if your coordinates were (1,2) (3,4) you would do
4-2 and 3-1

These answers become your “changes” now do change in y / change in x

In terms of the Example you would do 2/2 which would be 1 and the M value would be 1

Answer:

Parabola Graph (top-right)

Step-by-step explanation:

A graph represents a function given that none of the x-coordinates have more than one corresponding y-coordinates. Consequently, if a graph contains two or more different points with the same x-coordinate, then that graph does not represent a function.  

An easier way of finding out whether a graph represents a function is through the vertical line test. In order to perform the vertical-line test, imagine dragging a ruler held vertically across the graph from left to right. A graph is a function if the edge of the ruler crosses the graph only once for every x -value.  

Out of all the given options, the graph of an upward-facing parabola represents a function (top-right graph), as each vertical line contains only one point. Please see the attachment, where I performed the vertical line test.

3) Abhasra and Lisa each improved their yards by planting rose bushes and geraniums. They
bought their supplies from the same store. Abhasra spent $219 on 30 rose bushes and 11
geraniums. Lisa spent $420 on 6 rose bushes and 44 geraniums. Find the cost of one rose bush
and the cost of one geranium.

(EXPLAIN HOW DONE)

Answers

Answer:

Step-by-step explanation:

Let R and G stand for the prices of rose bushes and geraniums, respectively.

We are told that:

Abhasra:  30R + 11G = $219

Lisa:  6R + 44G = $420

Two equations and two unknowns.  Eliminate one of the variables by substitution:

Let's start with

6R + 44G = $420

and try to eliminate the G.  We note that the first equation,  30R + 11G = $219, can be multiplied by 4 to bring the geraniums up to the same as in the second equation:

6R + 44G = $420

4*(30R + 11G = $219) = 120R + 44G = 876

Now subtract this equation from the first:

   6R + 44G =  $420

-120R - 44G = -$876

 -114R           =  -456

  R = 4:   Rose bushes are $4 each.

Now use R= $4 in either equation to find G:

6R + 44G =  $420

6($4) + 44G =  $420

 $24 + 44G =  $420

44G = $396

    G = :  Geraniums are $9.00 each.

Read the story.The Speech A hush fell over the crowd as Samir approached the stage; he took a deep breath and tried to still the tremble in his hands. He had rehearsed the speech for days, practicing late into the night when the house was quiet. The night before, he had been putting the finishing touches on the speech when his mother snuck up the stairs and stopped by his bedroom door with a mug of tea. It looks like you will need this. Hows it coming? She tucked the long end of her sari under her leg and sat on his bed. The familiar smell that reminded him of trips to India tickled his nose as he took the warm mug from her; he pressed it to his lips and took a long sip. I dont think theyre going to understand it. Its okay if they dont understand it in their brains; its more important that they feel it here. She pressed her hand to his heart. My friends dont know what you went through to get here, and I want to get it just right because I need them to like the story. Your friends will like you no matter what. Practice it one more time, and then you need to get some sleep. He stared at the words that he had painstakingly crafted to tell the story of how his parents had immigrated to the United States from India. Even though he hadnt been born at the time, he could feel the heat on their skin as theyd packed up their belongings in Mumbai and boarded the plane for their new lives. After a twenty20-hour flight, they landed in the chill of Chicago; they hadnt brought enough heavy clothes with them and had to buy sweatshirts from the airport store before stepping out into snow for the first time. His mother had danced around in the swirling white like a fascinated child, tasting flakes on her tongue before the cab whisked them away to their new lives. He didnt know how his parents got by in those early days of loneliness and isolation, when they didnt know their neighbors and couldnt find their favorite spices or flavors in the local grocery store. He imagined his homesick mother making pungent curry in the tiny kitchen of the apartment that was their first homecurry that she didnt share with anyone except her husband because he was the only person she knew. Eventually they had made a life there, and one year after theyd brought Samir home as a newborn, his younger sister Aarti was born, and they became a family of four. Each year that his parents lived in Chicago, they spoke about Mumbai like it was more of a memory. Samir grew up hearing stories of Mumbai and taking summer trips where he heard his parents speak a language that was clumsy on his own English-speaking tongue. He couldnt imagine leaving his life and moving herefar away, but he knew that his parents had done it for him and his sister. It was the ultimate sacrifice, his mother had said, but it was worth it. When he had finished rehearsing his speech for his mother, she dabbed her face, and he knew she was crying. He didnt need to ask how the speech washer expression told him that it was perfect. Samirs thoughts came back to the present moment as he cleared his throat and stepped onto the stage in front of the entire middle schoolhis friends and teachers were all here. He had often felt different from his peers and wanted so much for them to understand his story. But looking out into the crowd at all the different faces he realized that his peers must have their own stories to tell as well. Perhaps they wanted to be understood, too. He realized the only way to be understood is to share those stories. Perhaps if he shared his own story, others would share theirs, too. Perhaps it would help them to understand one another. He found his moms eyes in the middle of the front row. When she nodded, he began. Im going to tell the story of how my parents became American citizens.How does the theme that stories can help us understand one another develop in "The Speech"?The theme develops through the author's depiction of how Samir changes from feeling different and separate from his peers to feeling not so different and comfortable with them after his mother tells him their family story.The theme develops through the author's depiction of how Samir learns to appreciate his classmates' different stories by listening to what their families went through.The theme develops through the author's depiction of how Samir feels more comfortable and confident delivering his speech after his mother offers him some tea and listens to what he has to say.The theme develops through the author's depiction of how Samir feels different and misunderstood before giving his speech but feels more comfortable and accepted once he realizes that everyone has a story of their own.
