Solve For X For A And B

Answers

Answer 1

Answer:

A. x = 3B. x = 3

Step-by-step explanation:

Question A

Using the proportions of similar triangles:

(7x + 4 + 15)/(12 + 20) = 15/12(7x + 19)/32 = 5/47x + 19 = 407x = 21x = 3

Question B

(6x - 3)/(6 + 4) = (6x - 3 - 6)/63(2x - 1)/10 = 3(2x - 3)/66(2x - 1) = 10(2x - 3)3(2x - 1) = 5(2x - 3)6x - 3 = 10x - 1510x - 6x = 15 - 34x = 12x = 3

If a original image is 2 inches and a scale drawing is 3.5 inches what is the scale factor?

Answers

Answer:

Step-by-step explanation:To find the scale factor of an original and a scale drawing, set up a ratio of the original length and the length of the drawing. Then simplify the ratio. A scale factor may be expressed by the ratio or by a positive number.A scale factor expresses the relationship between two lengths. It can be expressed as a ratio or a positive number. Let's look at some examples. If the original image is 4 inches, and the scale drawing is 8 inches, we can say that the scale factor is 4:8, but we must simplify that ratio, making it 1:2. We can also write the scale factor as a number by dividing 8 by 4 for a scale factor of 2.

That example is pretty straightforward, but let's look at something a bit more complicated. Let's say we have an original image that is 4 inches and a scale drawing that is 9.5 inches, and we want to find the scale factor. We cannot write the ratio 4:9.5, because ratios do not allow decimals or fractions. We must simplify the ratio. This involves getting rid of the decimal. To do this, we multiply 9.5 by 2 and get 19. What we do to one element of the ratio, we must do to the other, so we multiply 4 by 2 for 8. Our ratio looks like this: 8:19. Because 19 is a prime number, we cannot simplify further. This scale factor of 8:19, then, tells us that for every 8 inches in the original, the scale drawing will have 19 inches. We can also express the scale factor as 2.375 (19 divided by 8).

We'll try one more example. We have an original image that is 1.25 inches and a scale drawing that is 4 inches. Again, we cannot write a ratio with decimals, so we can't leave our scale factor as 1.25:4. We must simplify. This time, we must get rid of the decimal by multiplying each side by 4, so we have 5:16. We cannot simplify this ratio any further, but we can express it by the number 3.2 (16 divided by 5).

What is the ratio of point E to DC?

please answer with step by step explanation​

Answers

Answer:

[tex]3:5[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that:\\AB\ is\ a\ Line\ Segment\ that\ has\ Points\ A\ and\ B,\ that\ are\ it's\ two\ End-Points.\\Now,\\Point\ C\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AC\ and\ CB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:2.\\\\Point\ E\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AE\ and\ EB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:3.\\\\Point\ D\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AD\ and\ DB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:4.\\\\[/tex]

[tex]Now,\\For\ Point\ C,\\Total\ no.\ of\ parts=1+2=3\\Length\ of\ AC=\frac{1}{3}x\\Length\ of\ CB=\frac{2}{3}x\\\\For\ Point\ E,\\Total\ no.\ of\ parts=1+3=4\\Length\ of\ AE=\frac{1}{4}x\\Length\ of\ EB=\frac{3}{4}x\\\\For\ Point\ D,\\Total\ no.\ of\ parts=1+4=5\\Length\ of\ AD=\frac{1}{5}x\\Length\ of\ DB=\frac{4}{5}x\\[/tex]

[tex]Now,\\Lets\ move\ onto\ some\ REAL\ calculations!!\\We\ firstly\ observe\ that,\\AD+DC=AC\\Hence,\\\frac{1}{5}x+DC=\frac{1}{3}x\\DC=\frac{1}{3}x-\frac{1}{5}x\\DC=\frac{5-3}{15}=\frac{2}{15}[/tex]

[tex]We\ secondly\ observe\ that,\\AD+DE=AE\\Hence,\\\frac{1}{5}x+DE=\frac{1}{4}x\\DE=\frac{1}{4}x-\frac{1}{5}x\\DE=\frac{5-4}{20}=\frac{1}{20}[/tex]

[tex]Now,\\We\ know\ that,\\DE+EC=DC\\Hence,\\\frac{1}{20}x+EC=\frac{2}{15}x \\EC=\frac{2}{15}x-\frac{1}{20}x\\EC=\frac{40-15}{300}x\\EC=\frac{25}{300}x=\frac{1}{12}x\\\\By\ comparing\ DE\ and\ EC,\\Length\ of\ DE=\frac{1}{20}x\\Length\ of\ EC=\frac{1}{12}x\\The\ ratio\ of\ Lengths\ of\ DE\ to\ Length\ of\ EC=\frac{1}{20}x:\frac{1}{12}x\\We\ know\ that,\\Ratio's\ are\ merely\ fractions\ represented\ by\ ':'.\\Hence,\\\frac{1}{20}x:\frac{1}{12}x\\=\frac{\frac{1}{20}x}{\frac{1}{12}x}\\[/tex]

Answer:

y = 4x

Step-by-step explanation:

formula is y=kx, where k is factor of proportionality

Looking at the graph where y and x meet...

2/0.5 = 4 so 2 = 4(0.5)

Therefore, 4 is k (constant)

4=4(1)

[tex]\huge\boxed{\tt{x = 11 , y = 1}}[/tex]

Step-by-step explanation:

x + y = 12 -------------------------(1)

2x + 5y = 27 --------------------(2)

Multiply (1) by 2

2(x+y) = 12 * 2

2x + 2y = 24 --------------------(3)

Subtract (3) from (2)

2x + 5y - ( 2x + 2y ) = 27 - 24

2x + 5y - 2x - 2y = 3

5y - 2y = 3

3y = 3

Divide 3 to both sides

y = 1

Put y = 1 in (1)

x + 1 = 12

x = 12 - 1

x = 11

So,

x = 11 , y = 1

Find the perimeter and area of this shape

Answers

Answer:

Area: 38.48u²   Perimeter: 24.995u

Step-by-step explanation:

This is a quarter of a circle. You can use the formula to find the area of a full circle and then divide it by 4 to find the area of a quarter circle.

The radius is 7. So..

A = πr²/4 = π × 7²/4

= π × 49/4

= 12.25π

≈ 38.48u²

You have to find the circumference of the full circle in order to find the perimeter of this shape. The circumference is πd.

To find the diameter of a circle you multiply the radius by 2.

7 × 2 = 14

P = π14

≈ 43.98

Then, you divide that number by 4 because the arc (the curved part) is a quarter of the circumference.

43. 98 ÷ 4 = 10.995 - This is the length of the arc.

Now you add all the measurements:

7 + 7 + 10.995 = 24.995u

I hope this helps! :)

Answers

Math can help you if you ever wanna build a desk in the future;)

Maths can be used in the day-to-day shopping at home groceries and vegetables etc.

What is maths?

Numbers, formulae, and related structures, shapes, and the spaces in which they are contained, as well as quantities and their variations, are all covered in the field of mathematics.

An example of daily life is if you are going to the market to purchase fruits the cost of 1 kg of apple is 200rs but you want to buy 30 rs apple only. Then the amount in kg for the 30rs apple will be calculated by using maths.

200rs apple  = 1 kg

1 rs apple = 1 / 200 kg

30 rs apple = ( 1 x 30 ) / 200

30 rs apple = 0.15 kg or 150 grams

In this way, you will get the exact amount of apple for 30 rupees amount by using mathematics

Therefore, maths can be used in the day-to-day shopping at home groceries and vegetables, etc.
