I WILL GIVE BRAINLIEST PLS HELP ME I NEED HELP, Samantha drew a scale drawing of the floor area covered by her couch on a grid that represented the floor area in her living room. She used the scale 1 cm = 1.25 ft.
To the nearest hundredth of a square foot, What is the floor area covered by Samantha's couch?

Answer:

87˚

Step-by-step explanation:

Since they have equal angles we can make this equation:

3x + 57 = 8x + 7

5x = 50

x = 10

now we can substite x back into one of the equations

8x + 7

8(10) + 7

80 + 7

87

Answer:

116.67 m

Step-by-step explanation:

Two triangles are said to be similar if their corresponding angles are equal and the ratio of their sides are in the same proportion.

From the image attached:

∠A = ∠C = 90° (right angled triangle).

∠ABE = ∠CBD (vertically opposite angles are equal to each other)

The angle-angle similarity postulate states that If two angles of one triangle are equal to two angles of another triangle, then both triangles must be similar. Hence:

Since, ∠A = ∠C and ∠ABE = ∠CBD, we can say that ΔABE and ΔCBD are similar triangles. Since they are similar, the ratio of their corresponding sides is equal. Therefore:

BC / AB = CD / AE

BC = 140 m, AB = 30 m, AE = 25 m

substituting:

140 / 30 = CD / 25

CD = (140 / 30) * 25

CD = 116.67 m

The width of the canal = CD = 116.67 m

Answer:

It is proportional

Step-by-step explanation:

y=Kx

because it crosses the orgin

CRoC=Cop

Answer:y=-2x+6

Step-by-step explanation:

You want to find the equation for a line that passes through the point (4,-2) and has a slope of -2.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was -2. So you can right away fill in the equation for a line somewhat to read:

y=-2x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(4,-2). When x of the line is 4, y of the line must be -2.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the -2 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (4,-2).

So, why not plug in for x the number 4 and for y the number -2? This will allow us to solve for b for the particular line that passes through the point you gave!.

(4,-2). y=mx+b or -2=-2 × 4+b, or solving for b: b=-2-(-2)(4). b=6.

Answer:

112%

Step-by-step explanation:

The percentage of its capacity is calculated as

Number of people / Maximum Occupancy × 100%

Number of people = 84 people

Maximum Occupancy = 75 people

Hence:

84 people /75 people × 100

= 1.12 × 100

= 112%

Therefore, the percentage of its capacity that is 84 people is 112 %

Answer:

Nothing

Step-by-step explanation:

There is no real question or graph

Answer:

40 units

Step-by-step explanation:

This question is essentially asking the perimeter of the traingle

We can easily find the sides AC and BA and while you can use the distance formula to find the last side this is a right triange so we will take an easier approach

So because AC has the same y we can very easily figure out how far apart they are by subtracting (or counting) the x values

For me I got AC= 15

AB is kind of the same deal but instead subtract the y value

I got BA= 8

We can now use the a^2+b^2=c^2 formula to get the length of the last side

8^2+15^2=c^2

This means that 289=c^2

take the square root of both sides to get

c=17

The final step is to get the perimeter which is 17+8+15 or 40  

Answer:

The man or woman that entered the room was 55 years of age.

Step-by-step explanation:

If we add up all the ages together, it is 95. When the other person walks in, the mean changes to 25. If you do the math, or if you count, the man or woman that enters is 55, which when added together, gives 150. divided by 6 equals 25.

Answer: The explanatory variable goes in the horizontal axis.

Step-by-step explanation:

The explanatory variable is the variable that can be manipulated in an experiment. This is also called (and more commonly) the independent variable. This is the variable we usually "input" in a system, with the objective of observing the change in the response variable (also called the dependent variable, because it depends on the independent variable).

Usually, we write the explanatory variable on the horizontal axis and the response variable on the y-axis.

Then the correct answer would be C: /.

This is only because m is defined ONLY as a response variable, there are a lot of experiments with two variables, where we can use each of the variables as the explanatory variable.

And also there are some cases where in order to make the graph easier to read, we do not use the explanatory variable in the horizontal axis, instead, we may use some transformation or something alike, but those are really special cases.

Answer: B

Answer:

x = 17

Step-by-step explanation:

4x-10 and 58 are alternate interior angles since the lines are parallel

Alternate interior angles are equal.

4x-10 = 58

Add 10 to each side

4x-10 +10 = 58+10

4x = 68

Divide each side by 4

4x/4 = 68/4

x = 17

(2x - 5) (x + 1)

Step-by-step explanation:

2x2 - 3x - 5 = 0

(2x - 5) (x + 1) = 0

Answer:

x+4

Step-by-step explanation:

If you plug in the answer choices (x+4, x-4, x+2, x-2) into (x-1) (insert solution), x+4 gives you x^2+3x-4. :)
