Please help! A robotic vacuum cleaners can clean 2 square feet of carpet in 8 minutes. About how long does it take for it to clean a carpet covering a room with the dimensions shown below?

Answer:

They only intersect once. (Correct letter is B)

Step-by-step explanation:

Slope Intercept Form:

2x - 4y = 3

-2x        -2x

________

-4y = -2x + 3

Switch the signs of all of the numerals since you cannot have a negative 'y' value.

4y = 2x - 3

----   ---------

4         4

y= 1/2x - 3/4

-----------------------------------------------------------------------------------------------------------------

7y - 5x = 8

    +5x  +5x

----------------

7y = 5x + 8

----   ---------

7        7

y= 5/7x + 1 1/7

-----------------------------------------------------------------------------------------------------------------

After graphing the lines, you then can see that the lines only ever intersect once.

Answer: 38 yd. plz mark me brainliest

Step-by-step explanation:

Your question has confusing details. So, I will rephrase as:

How many 2' x 4' would be needed for Bottom Plates and Double Top Plates on a Building 25' x 50' ?

Answer:

12.5 plates

Step-by-step explanation:

Given

Building dimension:

[tex]Length = 25ft[/tex]

[tex]Width = 50ft[/tex]

Plates

[tex]Length = 2ft[/tex]

[tex]Width= 4ft[/tex]

To do this, we have to divide the dimension of the building by the dimension of the plates

So, we have:

[tex]n = \frac{Length\ of\ Building}{Length\ of\ Plates}[/tex]

and

[tex]n = \frac{Width\ of\ Building}{Width\ of\ Plates}[/tex]

For the length, we have:

[tex]n = \frac{25}{2}[/tex]

[tex]n = 12.5[/tex]

For the width, we have:

[tex]n = \frac{50}{4}[/tex]

[tex]n = 12.5[/tex]

So, 12.5 of the plates are needed

Answer:

Slope = 1

y-intercept = 3

Step-by-step explanation:

Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of the line passing through two points (0, 3) and (-3, 0) will be,

Slope = [tex]\frac{3-0}{0-(-3)}[/tex]

Slope = 1

y-intercept of the line = distance between the origin and point of intersection of the line with y-axis

y-intercept = 3

Answer:

5 km

Step-by-step explanation:

From. The question, the triangle formed us a right angled triangle,

h km directly from starting point is the hypotenus, h :

Hypotenus = sqrt(opposite² + Adjacent²)

h = sqrt(4² + 3²)

h = sqrt(16 + 9)

h = sqrt(25)

h = 5 km

Answer:

Step-by-step explanation:

when you use elimination you want to set two of the terms, in the different equations,  equal to each other and then subtract the entire equation from the other,  so that the two terms cancel out.    Then you have an equation with one less variable in it.  :)

Answer:

7.5

35.2

1.5

20

Step-by-step explanation:

1. vertical angles are equal

(2x+17)=(4x+2)

15= 2x

x= 7.5

2. adjacent angles equal 180

(2m+8)+(3m-4)= 180

5m+4= 180

5m= 176

m= 35.2

3. (30s+5)=(20s+20)

10s= 15

s=1.5

4. 4p+5p=180

9p=180

p=20

sorry that took so long.  I was babysitting lol

Step-by-step explanation:

BC^2 + DC^2 = AC^2

6^2 + 4^2 =AC^2

36 + 16 = AC^2

52=AC^2

√52=AC

AC=7.2111

Answer:

-9x^2+13x+8

Step-by-step explanation:

Combine like terms-

(x^2 + 8x + 8) + (-10x^2 + 5x)

8x+5x = 13x

(x^2 + 8x + 8) + (-10x^2 + 5x)

-10x^2+x^2 = -9x^2

(x^2 + 8x + 8) + (-10x2 + 5x)

and 8 is just left over, so we put that all together and get...

-9x^2+13x+8

Good luck, have a great day!

Answer: 1.5 tons

Step-by-step explanation:

Given

The recycling center collected 48,000 ounces of aluminum can

An ounce is the unit of weight and it can be expressed in tons as

[tex]1\ \text{ounce}=3.125\times 10^{-5}\ \text{tons}[/tex]

[tex]\therefore 48,000\ \text{ounces} \equiv\ 3.125\times 10^{-5}\times 48,000=1.5\ \text{tons}[/tex]

Answer:

a.

2x+4x+3x=180 sum of interior angle of the triangle is 180

9x=180

x=180/9=20

b.

x-20+x+10+x-20=180sum of interior angle of the triangle is 180

3x-30=180

3x=180+30

x=210/3=70

c.x+10+x+20+x=180 linear pair

3x+30=180

3x=180-30

x=150/3=50

Answer:

A: x=20

Step-by-step explanation:

angles in a triangle always equal 180° so knowing this 2x+3x+4x=180

9x=180

9x÷9=x

180÷9=20

Answer:

2x° = 45°, 3x° = 67.5°

Step-by-step explanation:

Sum of angles in a triangle = 180°

2x+3x+3x=180°

8x=180°

x=22.5°

2x=22.5°x2=45°

3x=22.5°x3=67.5°

Yes you are correct

Step-by-step explanation:

Answer:

Actual Length: 27 feet - Actual Width: 15 feet - Actual Area: 405 feet

Step-by-step explanation:

First, to find the length, you have to divide 9 by 2 to get 4.5 and then multiply it by 6 to get the actual amount of feet. Then you divide 5 by 2 and multiply the quotient by 6 to get the actual width. Then, you take the actual length (27 feet) and multiply it by the actual width (15 feet) and you get an area of 405 feet

Answer:

25/28

Step-by-step explanation:

Answer:

D is the correct answer

Explanation:

the following function satisfies each output to its input for the set D

f(x)=x/2

let's check each pair:

0/2=0

-1/2=-0.5

-2/2=-1

-3/2=-1.5

-4/2=-2

the reason why A, B, and C can't be pairs of inputs and outputs x and y it's because a variable x can't have more than one y (that's a behaviour of an equation not a function!)

- in A x=-1 | y=2, -2 and this wrong

- in B x=3 | y=9, 16 and this wrong

- in C x=0 | y=0, 1 and this wrong

Answer:

5/9

Step-by-step explanation:

total number of odd numbers / total numbers in the bag = 5/9

Given:

So,

Outer radius = R = D/2

=> R = (80 ft)/2

=> R = 40 ft

Inner radius = r = d/2

=> r = (40 ft)/2

=> r = 20 ft

Area of paved pathway = πR² - πr²

= π(R² - r²)

= π(R + r)(R - r)

= π(40 + 20)(40 - 20) ft²

= π(60)(20) ft²

= 3.14 * 1200 ft²

= 3768 ft²

Answer:

what's the question?

Step-by-step explanation:

what the question

Answer:

The angle is 136 degrees because the 44 degree angle adds up to 180 since it is suplementary. so that means when u minus or take away 44 degrees from 180 it gives u 136.
