Four ninths plus nine eighteenths :]

Mathematics
1 answer:
goldenfox [79]2 years ago

Answer:  17/18

In words, this is seventeen eighteenths

==========================================

Work Shown:

4/9 + 9/18

8/18 + 9/18 ... see note below

(8+9)/18

17/18

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

note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.

The diagram below shows a visual representation of why 4/9 = 8/18.

In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.

Because it is three-dimensional, a form has these three spatial measurements: height, width, and ________.
AlexFokin [52]

Considering that it is a three-dimensional form, it's spatial measurements are height, width and length.

<h3>What are the measurements of a three-dimensional form?</h3>

A two-dimensional form has two dimensions, width and length. When there are three dimensions, the height is added.

In this case, height and width are already listed, hence the length is missing.

What is the area of the parallelogram (a) 168s sq inches b) 140 sq inches c) 130 sq inches d) 120 sq inches
irina [24]

Answer:

Step-by-step explanation:

Area of a parallelogram is given as the multiplication of its length by that of its height or breadth, however you call it.

In this question, you didn't state the length nor the breadth or height. You just listed the answers. It's very hard knowing the answer without having its dimensions. However, I can tell you that on the diagram or drawing you have there with you, multiply the two distance given to you together, it ought to give you one of the four options you listed above. Be it 168, 140, 130 or even 120 square inches.

Min Jee wants to build a small patio using either brick or paver stones.
Anvisha [2.4K]
Brick = 3.5 in by 7.5 in and costs $0.59
Paver = 8.4 in by 8.4 in and costs $1.88

The small patio's area = 3430 square inches
The Area of 1 Brick = 26.25 square inches
The Area of 1 Paver = 70.56 square inches

The # of Bricks to complete the Patio will be:

Patio's Area / the Area of 1 Brick = # of Bricks to complete the patio
3430 square inches / 26.25 square inches = 130.67 = 131

Then, multiply the # of Bricks to complete the patio by the amount that 1 brick costs:

131 * $0.59 = $77.29

It will take $77.29 to complete the Patio with bricks. 

The # of Pavers to complete the Patio:

Patio's Area / the Area of 1 Paver =  # of Pavers to complete the Patio
3430 square inches / 70.56 square inches = 48.6 = 49

Then, multiply the # of Pavers to complete the patio by the amount that 1 Paver costs:

49 * $1.88 = $92.12

Cost of Bricks to complete Patio = $77.29
Cost of Pavers to complete Patio = $92.12

To conclude, Bricks would cost less by $14.83.
