If each 2 cm on the scale drawing equals 10 feet, what are the actual dimensions of the room? (5 points) Length = 11 feet, width = 9 feet Length = 30 feet, width = 20 feet Length = 8 feet, width = 12 feet Length = 22 feet, width = 20 feet

Answer:

Parallel = lines with the same slope

Perpendicular = lines whose slopes are negative reciprocals (i.e. product is –1)

Step-by-step explanation:

The first part: circle b, c, d, f (1 ³/₄ is another way of saying ⁷/₄), and h (a horizontal line y = b has a slope of 0)

The second part: circle a, d (1 ⁴/₇ is another way of writing ¹¹/₇, the negative reciprocal of –⁷/₁₁), and e

Hope this helps! Have a great day!

Answer:

See answers below

Step-by-step explanation:

Using the coordinates from the table (0, 12) and (1, 14)

m = 14-12/1-0

m = 2/0

m = 2

Hence the slope of the table is 2

y intercept occurs at x = 0

Substitute m = 2 and (0,12) into the equation y = mx+c

12 = 2(0) + b

12 = b

b = 12

Hence the y-intercept is 12

Get the equation

Recall that y = mx+c

y = 2x + 12

Hence the required equation is y = 2x+12

Step-by-step explanation:

Answer:

(4,-4)

x=4

y= -4

Step-by-step explanation:

We know that y is equal to and so we can plug the y value in for x into the other equation

-2x+5(-x)= -28

Solve for x

-2x-5x= -28

-7x= -28

x=4

Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y

y= -(4)

y= -4

Answer:

Conversion a mixed number 4 1/

2

to a improper fraction: 4 1/2 = 4 1/

2

= 4 · 2 + 1/

2

= 8 + 1/

2

= 9/

2

To find new numerator:

a) Multiply the whole number 4 by the denominator 2. Whole number 4 equally 4 * 2/

2

= 8/

2

b) Add the answer from previous step 8 to the numerator 1. New numerator is 8 + 1 = 9

c) Write a previous answer (new numerator 9) over the denominator 2.

Four and one half is nine halfs

Add: 9/

2

+ 12 = 9/

2

+ 12/

1

= 9/

2

+ 12 · 2/

1 · 2

= 9/

2

+ 24/

2

= 9 + 24/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 1) = 2. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 1 = 2. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - nine halfs plus twelve = thirty-three halfs.

Add: the result of step No. 2 + 5/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 7) = 14. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 7 = 14. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - thirty-three half's plus five sevenths = two hundred forty-one fourteenths.

Step-by-step explanation:

The sum of 4[tex]\frac{1}{2}[/tex] and 8[tex]\frac{3}{14}[/tex] is 12[tex]\frac{5}{7}[/tex].

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Let the required number be n.

According to the question,

the sum of 4[tex]\frac{1}{2}[/tex] and n is equal to 12[tex]\frac{5}{7}[/tex].

In numeric form,

4[tex]\frac{1}{2}[/tex] + n = 12[tex]\frac{5}{7}[/tex]

Simplifying,

9/2 + n = 89/7

Substituting constant to term one side,

n = 89/7 - 9/2

n = 115/14

n = 8[tex]\frac{3}{14}[/tex]

Therefore, the number is 8[tex]\frac{3}{14}[/tex].

Answer:

F (10,1)

Step-by-step explanation:

Answer:

See the attached images

Step-by-step explanation:

We're reflecting this image over the line y = –1, right?

This means we need to copy this image over the line like a mirror does a reflection. It isn't exactly what we got before, though—it's flipped backward, just like text when you look at it in a mirror!

First, look where points E and F are. They're two squares below the line. That means we count two squares up to reach y = –1… then count up another two squares to reflect the points across the line.

Next, look at point G. This is what I personally feel is easier: this point has a y-coordinate of –8. This makes it 7 squares below y = –1. To get its new y-coordinate, we add 7 to –1 to get y = 6.

The x-coordinates of the points don't change here; the line the shape is reflected over is a horizontal line. If the line were vertical, we'd only change the x-coordinates and not the y-coordinates. If the line were a linear function like y = x, we'd reflect our x-coordinates and y-coordinates.

Another way to think of it here: how squares below the line is each point? Then multiply that number by 2 and add it to the initial y-coordinate to find its new position.

Forgive me for the weird dots in the last image. I got frustrated and drew the triangle with my pinky finger because I can't quite draw nor write with a mouse yet!!

Hope this helps you understand! Have a great day!

Answer:

55°

Step-by-step explanation:

We know that exterior angle of a triangle is equal to the sum of two opposite interior angles

so

x = 21° + 34°

= 55°

Answer:

D

Step-by-step explanation:

To be an arithmetic sequence, the numbers have to be added or subtracted by a constant number. D is not the answer because -2+6 equals 4, but 4+6 doesn't equal -6, so D cannot be a arithmetic sequence.
