Answer: 66 yd

Explanation: It might seem like a very difficult shape to find the area, but it is actually really simple. All you have to do is split this shape in multiple squares, then find each area of each square, then add up all the square's area to get the total area of the shape.

Notice: Please take a look at the image I included to see how I divided the shape.

Step 1.) Since the shape is in a weird shape that doesn't allow us to find the area by normal means, we will split it in workable shapes. In this case, splitting it in 3 rectangles is best option (see image below).

Step 2.) Find the dimensions of each rectangle you split. Since we have new shapes, let us find the dimensions of each shape now.

Notice: Some sides of the shapes are split in half, to find the total length of a side we just add up the splits of the side. In this example our length's of the Rectangle 1 and 3 where split by 2 and 5 yards.

Rectangle 1: Length: 7yd; Width: 4yd

Rectangle 2: Length: 2yd; Width: 5yd

Rectangle 3: Length: 7yd; Width: 4yd

Step 3.) With the new dimensions of each shape, apply the correct formula for the area of each rectangle to find the area of each rectangle.

Area = Length x Width

A= L x W

Rectangle 1: Area = 28

A = L x W

A = (7) x (4)

A = 28

Rectangle 2: Area = 10

A = L x W

A = (2) x (5)

A = 10

Rectangle 3: Area = 28

A = L x W

A = (7) x (4)

A = 28

Final Step 4.) Now that we have the area of each individual rectangle, let us combine all the areas to find the total area of the shape.

Rectangle 1 + Rectangle 2 + Rectangle 3 = 66

28+10+28 = 66

Note: If you have any questions please let me know. If not, I hope this helped. Your very welcome :-)

Answer:

The answer is 66yd squared.

Step-by-step explanation:

You multiply 13 by 7 and get 91. Next, you subtract 25 by 91. This will get you 66.

Lets start:

Picture 1:-

1. Length of EH= 12cm

2. Angle G= 55 degrees

Picture 2:-

1. Scale factor= 1/4 (I'm not sure about this but this is what I think it is ;-;)

2. Value of y= 28 cm

Picture 3:- [Picture 3 is cropped so I'm guessing its the last one so imma answer those questions :D]

1. Scale factor= 5 (Again I'm not sure but its my best guess)

2. Value of z= 5

Picture 4:-

1. Scale factor= 4 (I'm pretty sure you know that my scale factor answers are guesses so yea ;-;)

It'll help you understand how we solve these questions

Well anyways i hope this clears your concepts :D

Answer:

Step-by-step explanation:

EH is 12cm as the shape has been enlarged by scale factor two (all sides have been multiplied by 2).

Angle G remains the same at 55 degrees.

PART A

Scale factor for the triangle = 1/4

Value of y = 28cm

3) z = 5, scale factor = 5

Scale factor = 4

Side b = 12cm

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Answer:

Step-by-step explanation:

Answer:

45/8

Step-by-step explanation:

You divide 3 3/4 by 1 1/2

First turn the mixed numbers into improper fractions.

Multiply the whole number by the denominator then add the numerator. Keep the denominator the same.

3 3/4:

3 x 4 = 12

12+3

= 15/4

1 1/2 :

1 x 2= 2

2+1

= 3/2

now you're dividing 15/4 by 3/2

My teacher always taught me KFC:

Keep, change flip

Keep:

Keep the first fraction don't change it. 15/4 stays the same.

Change:

Change the division sign to multiplication.

Flip:

Flip the last fraction to its reciprocal.

In this case instead of it being 3/2, it will be 2/3

Next

Multiply straight across

15/4 x 2/3

15 x 2 = 30

4 x 3 = 12

30/12

Simplified would be 5/2 as an improper fraction

or

2 1/3 as a mixed number

I am so sorry but I don't know how to explain the 2nd question without it making any sense, I hope someone else can for you! I hope I helped with the first one!

Answer:

Step-by-step explanation:

15/4 x 2/3

Answer:

Last option: Each term in the first sequence is four times the corresponding term in the second sequence

Step-by-step explanation:

This is because the numbers increase by products of the 4 times table. Here, 0+4=4 is followed by 0+8=8 and so on. This also follows the sequence 4×1=4, 4×2=8 and so on.

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

The answer is 8 so its a direct proportion

I think...

The constant of Proportionality is 8.

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

The correct answer is (D) -2x - 8.

To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:

-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3

Then we can simplify using the properties of multiplication and division:

-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3

Finally, we can combine like terms:

-2x - 5 - 3 = -2x - 8

The correct answer is therefore (D) -2x - 8.✅

Answer:

y = 70x + 35

Step-by-step explanation:

$75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)

the +35 is the tips extra/ constant that will be added after the jobs are done.

x is the amount of car washes done

y would be the profit received.

thus y = 70x + 35 (profit = value of car wash * number of cars washed + tips)

Answer:

Step-by-step explanation:

Profit = Income less outgo

         = (car wash income + tips) - (supplies)

$250 = ($75n + $35) - ($5n), or

$215  = $70n     (where n represents the number of cars washed)

This comes out to n = $215/$70, or approximately 3 car washes.

Answer:

Step-by-step explanation:

So a simple set is to find the multiplier given for the roses and use it for the carnations. 2 goes into 4 2 times, 6 3times, 8 4 times, and 10 5 times. Therefore:

8*2,8*3,8*4,&8*5

| 8 | 16 | 24 | 32 | 40 |

The answer is 10 roses and 40 carnations.

A simpler way is to say there are 4 times as many carnations as roses since the ratio is 2:8. Giving 2 roses x 5 bouquets = 10 roses.

And 10 x 4 = 40 carnations.
