You find the area of a rectangle by multiplying length times width. I don't know how else to explain that all of the answers are incorrect.

Answer:

100m^2

Step-by-step explanation:

square has equal sides.

To find the area of the square, the formula is:

Area= length times width

So for square ABCD, 10*10=100m^2

Answer: It is 250

Step-by-step explanation: you would add 40 and 70 together which is 110 and then you would subtract 360 from 110 and you answer would be 250.

Answer:

x = 125

Step-by-step explanation:

Kindly check the image below

The problem we are looking at gives us the value of two intercepted arcs and wants us to find x ( which is an interior angle )

According to the image we can find an interior angle by adding the two intercepted arcs and then dividing the sum by 2

( Note that we are not given the direct intercepted arcs  of x. We are given the intercepted arcs of x's supplementary angle )

That being said we need to find x's supplement in order to find x

Using the image below as a reference

x's supplement = [tex]\frac{70+40}{2}[/tex]

[tex]70 + 40 =110\\\frac{110}{2} =55[/tex]

So x's supplement = 55

Now to find x

Remember that supplementary angles have a sum of 180°

That being said we can find the missing angle (x) by subtracting the given angle (55) from 180

so x = 180 - 55

180 - 55 = 125

Hence x = 125

The answer is B! I'm 100% sure!

Step-by-step explanation:

8% of $72.60 means 0.08*72.6 which equals 5.808. 20% of $72.60 means 0.2*72.6 which equals 14.52. 14.52+5.808=20.328. 20.328+72.6=92.928 which rounds up to $92.93. I hope this helps! Have a great rest of your day!

Answer:

She paid a total of $92.93 at the salon

Step-by-step explanation:

Well it costed $72.60 but then she did the sales tax which is 8% of 72.60 and then she did a tip which was 20% of 72.60. 8% of $72.60 is 5.81 and 20% of 72.60 is 14.52. Then you would add them to get $20.33 and then you would add the $20.33 to the $72.60 to get $92.93. SO she paid a total of $92.93 at the salon.

$5.81 + $14.52 = $20.33

$20.33 + $72.60 = $92.93

Answer:

28.26

Step-by-step explanation:

A = area of a sector

π = 3.14

r = 9

θ = 40

A=πr²*θ/360=3.14*81*40/360=28.26

Answer: B I believe

Step-by-step explanation:

AB = CD

So option C is right

Option (3) is correct. The slope of CD = 1/2.

"A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees, opposite sides are parallel and adjacent sides are perpendicular.

For the given situation,

Consider the rectangle ABCD,

The slope of [tex]AB=\frac{1}{2}[/tex]

The slope of parallel sides are equal. Here AB and CD are parallel sides.

So, slope of [tex]AB=CD[/tex].

Hence we can conclude that the slope of CD = 1/2. So, option (3) is correct.

Answer:

I remember taking this too. So, the correct answer is A! I SWEAR ITS RIGHT!

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

First, you look at which way it is going. From left to right, the line is going down, so the slope is negative. Change in y is 3 and change in x is 1. From any two points on the line, the y value changes by 3 every time the x value changes by 1.

Answer:

-3

Step-by-step explanation:

slope = rise/run

rise = vertical distance

run = horizontal distance

Step 1. Find two easy to read points on the line. Use points on intersections of grid lines.

For example, choose points (0, -3) and (-1, 0).

Step 2. Start at one point, say (0, -3). We must go to the other point using only vertical and horizontal moves. Go up 3 units. That is a rise of +3. It's positive 3 since up is positive. Now go left 1 unit. That is a run of -1. It is negative because going left is negative.

Step 3.

slope = rise/run

slope = 3/(-1) = -3

Answer: slope = -3

Answer:  2:3=5

$50=5 units

divide both sides by 5

$10=1unit

times 2 both sides

$20=2 unit

if we times 3 of $10=1 unit

$30=3 unit

divided it is $20:$30

The scale of drawing is 1 inch : 27 inch

The scale factor is a measure for similar figures, who look the same but have different scales or measures. The scale factor states the scale by which a figure is bigger or smaller than the original figure.

Given that, the measurement of the tile = 27/4 inches

Side of the drawing = 1/4 inches

The scale of the drawing =

1/4 inch of drawing = 27/4 inch of tile

That means, 1 inch of the drawing = 27 inch of the tile

Therefore,

The scale of the drawing is 1 inch : 27 inch

Answer:

The cost for 1 necklace is $3.

Step-by-step explanation:

With the information provided, you can say that the amount spent in bracelets and necklaces is equal to the price per bracelet for the number of bracelets plus the price per necklace for the number of necklaces, which is:

c=3x+2y, where:

c is the total cost

x is the price per bracelet

y is the price per necklace

Now, you can say that c=21 and x=5 and solve for y to find the price per necklace:

21=(3*5)+2y

21=15+2y

21-15=2y

6=2y

y=6/2

y=3

According to this, the answer is that the cost for 1 necklace is $3.
