Determine which of the lines,if any, are parallel or perpendicular. Explain.

Answer:

35:15

Step-by-step explanation:

7:3=10 (7+3)

14:6=20 (14+6)

21:9=30 (21+9)

28:12=40 (28+12)

35:15=50 (35+15)

There is a more mathematical way to solve this but it isn't coming to mind rn so

Answer:

Slope intercept form is y = mx + b

m is slope

b is y intercept

y = -4/5x + -9

I only know that first one sry

Step-by-step explanation:

Answer:

yes.

Step-by-step explanation:

slope intercept form is y=mx+b

b is the y intercept, m is the slope, and x is x.

for

1. it would be

y= -4/5x -9

2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)

it would look like:

(5- -3) / (3-0) = (8/3)

Then plug in one of the sets of numbers for x and y, to get y intercept.

5=8/3(3)+b

b=-3

So.. slope intercept would be y=8/3x -3

Answer:

  about 106.5 units

Step-by-step explanation:

The length of each side is found using the distance formula:

  d = √((x2-x1)^2 +(y2-y1)^2)

For example, the length of side AB is ...

  d = √((9 -2)^2 +(1 -3)^2) = √(7^2 +(-2)^2) = √53 ≈ 7.28

The other side lengths are calculated the same way. The sum of side lengths of the given triangle is ...

  AB +BC +CA = 7.28 +13.34 +14.87 = 35.49

__

Multiplying each coordinate by 3 effectively dilates the triangle by a factor of 3 about the origin. That increases the perimeter by a factor of 3, so it is ...

  3(35.49) ≈ 106.5 . . . . units

_____

I find it convenient to use a calculator or spreadsheet to do the tedious calculations.

Answer:

area = m²/2π

Step-by-step explanation:

∵ circumference of circle = 2πr = m

∴ r = m/2π

∵ area of circle = πr²

∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π

Answer:

zero

Step-by-step explanation:

The computation of the remainder when the number would be divided by 35

Let the number be x

So if x is divided by 5 gives the remainder 0

x = 0

And, if x is divided by 7 gives the remainder 0

x = 0

So if x is divided by 35 so the remainder is also zero

Answer:

1 ÷ 2 pounds

Step-by-step explanation:

The computation is shown below:

As we know that

1 pound = 0.454 Kg

Peanut starting weight = 3 ÷ 4 of a pound.

In the case when  the bag is 2/3 full, so the weight is  

= 2 ÷ 3 × 3 ÷ 4

= 1 ÷ 2 pounds

Answer:

l = (x+7) units

Step-by-step explanation:

Given that,

Breadth of the rectangle, b = (x+7) units

Area of the rectangle, [tex]A=x^2+14x+49[/tex]

The area of a rectangle is given by :

[tex]A=lb\\\\l=\dfrac{A}{b}\\\\l=\dfrac{(x^2+14x+49)}{(x+7)}\\\\l=\dfrac{(x+7)^2}{(x+7)}\\\\l=(x+7)\ \text{units}[/tex]

So, the length of the land is (x+7) units.

Answer:

It has no solution, unless there's a specific way it needs to be solved

Step-by-step explanation:

Answer:

What is the concentration of H+ ions at a pH = 2?

⇒ 0.01 mol/L

What is the concentration of H+ ions at a pH = 6?

⇒ 0.000001 mol/L

How many more H+ ions are there in a solution at a

pH = 2 than in a solution at a pH = 6?

⇒ 10,000

Step-by-step explanation:

Answer:

What is the concentration of H+ ions at a pH = 2?

0.01

What is the concentration of H+ ions at a pH = 6?

0.000001

How many more H+ ions are there in a solution at a

pH = 2 than in a solution at a pH = 6?

10,000

Step-by-step explanation:

You have shaded 4/7=8/14

6/7=12/14

So you need to shade 12 boxes

Answer:

224/100 = 2 24/100

= 2 6/25

308/100 = 3 8/100

= 3 2/25

125/1000 = ⅛

444/1000 = 111/250

The equation is less than 30 so any number smaller than 30 are correct.

Answer:

58 markers

Step-by-step explanation:

52 + 6 = 58

Answer:

58 markers

Step-by-step explanation:

x-6=52 Set up the problem. "x" represents the number of markers.

 +6 +6 Add 6 to both sides to isolate x

x    =58

Answer:

1. $16

2.$61.75

3. $222

4.$130

Step-by-step explanation:

1.     20% of $20 is $4.

$20-$4=$16

2.    35% of $95 is $33.25.

$95-$33.25=$61.75

3.    $55.50 divided by 1-.75=222

4.     $78 divided  by 1-.40=130
