2. The units of density for a rectan-
gular piece of wood are
a. grams per milliliter.
b. cubic centimeters.
c. kilograms per liter.
d. grams per cubic centimeter.

Answers

Answer 1

Answer:

d. grams per cubic centimeter

Step-by-step explanation:

The unit for density is g/cm^3 because the formula for density is mass divided by volume. The standard unit for mass is grams, and volume is cm^3. So by dividing the two numbers, the unit becomes both units divided.

You have to add like terms.

7x and 6x are like terms. If you don’t do that, the answer will be wrong

If you add them, then it would be

13x + 18 = 4
Subtract 18 from each side
13x = -14
Divide both sides by 13 to get
X = -14 / 13
they subtracted 6x from 4. you can’t do that because 6x has a variable while 4 doesn’t. x = - 14/13

JK is formed by J(-12, 3) and K(8,-5). If
line r is the perpendicular bisector of JK, write
an equation for r in slope-intercept form??

Answers

Given:

JK is formed by J(-12, 3) and K(8,-5).

Line r is the perpendicular bisector of JK.

To find:

The equation of line r is slope intercept form.

Solution:

Line r is the perpendicular bisector of JK. So, it passes through the midpoint of J and K.

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-12+8}{2},\dfrac{3+(-5)}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{-2}{2}\right)[/tex]

[tex]Midpoint=\left(-2,-1\right)[/tex]

Slope of JK is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{-5-3}{8-(-12)}[/tex]

[tex]m=\dfrac{-8}{20}[/tex]

[tex]m=\dfrac{-2}{5}[/tex]

Product of slopes of two perpendicular lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]-\dfrac{2}{5}\times m_2=-1[/tex]

[tex]m_2=\dfrac{5}{2}[/tex]

The slope of perpendicular line r is [tex]\dfrac{5}{2}[/tex] and it passes through (-2,-1). So, the equation of perpendicular line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-(-1)=\dfrac{5}{2}(x-(-2))[/tex]

[tex]y+1=\dfrac{5}{2}(x+2)[/tex]

[tex]y+1=\dfrac{5}{2}x+5[/tex]

[tex]y=\dfrac{5}{2}x+5-1[/tex]

[tex]y=\dfrac{5}{2}x+4[/tex]

Therefore, the equation of line r is [tex]y=\dfrac{5}{2}x+4[/tex].

The required equation of line "r" in slope-intercept form is y = 5/2x + 15

First, we need to find the equation of a line in slope-intercept form as

y = mx + b

m is the slope of the line

b is the y-intercept

Given the coordinate points  J(-12, 3) and K(8,-5)

Get the slope of the line

Slope  = -5-3/8+12

Slope = -8/20

Slope - -2/5

Slope of the line "r" perpendicular is 5/2

Get the y-intercept of line r

Substitute (8, -5) and m = 5/2 into y = mx + b

-5 = -5/2(8) + b

-5 = -20 + b

b = 15

Hence the required equation of line "r" in slope-intercept form is y = 5/2x + 15

What is a group of objects that share common characteristics and are well-defined?​

Answers

Answer:

The options as included in the attachment section are:

A. real numbers B.Cardinality C.element D.Set

The answer is D. Set

Step-by-step explanation:

In mathematics, a set is a group of well-defined objects that share common characteristics as rightly stated in this question. So in a mathematical calculation, the elements or objects collected as a group is called SET. The types of set include empty set, finite set, infinite set, universal set etc.

- Since set represents the whole collection or group, each object, which can be number, letter etc. in the group is an ELEMENT. Likewise, the cardinality of a set refers to the number of elements contained in a particular set.

Answers

Answer:

y2 -y1 =4 - y  = 2      y has to = 2 because your slope m= - 2/7

Step-by-step explanation:

( 10 , y )  (3 ,  4)

We have that for the Question "(10, y) and (3, 4); m= -2/7 find missing value" it can be said that

The value of y is

From the question we are told

(10, y) and (3, 4); m= -2/7 find missing value

Generally the equation for the slope m  is mathematically given as

[tex]m=\frac{y2-y1}{x2-x1}\\\\Therefore\\\\m=\frac{y2-y1}{x2-x1}\\\\-2/7=\frac{4-y}{3-10}\\\\-2/7*-7=4-y\\\\y=4((-2/7)*-7)\\\\[/tex]

Answer:

c 60.5 ft x 2ft

Step-by-step explanation:

60.5 ft x 2 = 121 ft

The required possible side length of the tablecloth is 11ft x 11ft.

Given that,
Mrs. Sullivan wants to make a square tablecloth for her dining room table. She has 121 ft? of fabric. What are the possible side lengths of the tablecloth to be determined.

What is the square?

A square is for sided regular polygon, where the length of all sides is identical and the angle between the adjacent side is 90°.

Here,
She has 121 ft² of fabric.
She wants to make a square tablecloth for her dining room table.\

Area of the square = a²
121 = a²
a = √121
a = 11 ft

What best describes the relationship between the following two lines?
y = 2x +4
y = –2x +
4
Parallel
Perpendicular
Neither parallel nor perpendicular

Answers

Answer:

Neither parallel nor perpendicular

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Define lines

y = 2x + 4

y = -2x + 4

Parallel lines have the same slope but different y-intercepts. If the 2 lines were parallel, their m value would be the same. If the original line's slope is 2, the parallel line's slope would also be 2. Therefore, they aren't parallel.

Perpendicular lines have the negative reciprocal of the original slope. If the 2 lines were perpendicular, one slope would be 2 and the other slope would be -1/2. Therefore, they aren't perpendicular.

Therefore, our answer is neither parallel nor perpendicular.

Answer:

Neither parallel nor perpendicular.

Step-by-step explanation:

y =  2x +4

y = -2x + 4

The 2 slopes are 2 and -2.

If they were equal the 2 lines would be parallel.

If  they had the relationship  slope1 * slope2 = -1 they would be perpendicular.

They are neither so its the last choice.

Yes. 8° with a rise of negative 7 would look like this 8+-7= 1.

I'm not familiar with the iniger game but here's my best take on the questions

1) no because a positive plus a positive is positive

2) yes, positive plus negative can be negative if the negative is bigger than the positive ex.(5-15=-10

3) yes, negative plus negative is negative

sorry if this took too long but tried my best to hurry

OKOKOKOKOKOKOKOK

When the table says that there has been a RISE, that means that you should ADD. When the table says there has been a FALL, that means you should SUBTRACT.

The second row and the second column is saying a RISE, meaning that you should ADD 8 and 2. 8 + 2 = 10. So the answer for that one would be 10 degrees celcius (third column, second row.) The numbers in bold are your equation for the second row and fourth column.

Here are the rest: AT MEANS AFTERNOON TEMPERATURE :)

3rd row: AT = -8 [degrees celcius] EQUATION: -2 - 6 = -8

4th row: AT = 3 [degrees celcius] EQUATION: -4 + 7 = 3

5th row: AT = -3 [degrees celcius] EQUATION: 6 - 9 = -3

6th row: AT = -10 [degrees celcius] EQUATION: -5 - 5 = -10

7th row: AT = 0 [degrees celcius] EQUATION: 7 - 7 = 0

Woohoo! We're done with that part now.

(b) So, as I said before, a RISE means you must ADD. If you have a rise in -7 degrees celcius, how would you write that mathematically? You would write it like this: + ( - 7 ). You are ADDING NEGATIVE SEVEN. I know it sounds weird, but it is what it is. NOW. Adding negative 7 IS THE EQUIVALENT of saying subtract seven. Here's an example:

10 + ( - 7 ) = 3 (this is true)

10 - 7 = 3 (this is also true)

Therefore, for b you would say that you agree because +(-7) is the equivalent of say 'minus 7'.

Hopefully, you can use what I explained to help you with number 2. If you need more help you can just comment on this post and I'll help you. :))
