The work that Yi did to find the greatest common factor of 42 and 63 is shown below. Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42 Factors of 63: 1, 7, 9, 63 The greatest common factor is 7. What is Yi's error? Yi did not list all the factors of 63. Yi listed multiples for each number instead of factors. Yi did not list all the factors of 42. Yi found the least common multiple.

(x + 6) (3x - 2)

x (3x - 2) + 6 (3x - 2)

3x² - 2x + 18x - 12

3x² + 16x - 12

Therefore, (x + 6) (3x - 2) as a trinomial is 3x² + 16x - 12

Answer:

BD = 12 :)

Step-by-step explanation:

Alright, we'll need the Pythagorean theorem for this!

So, the length of AC is 10. That means the lengths of AD and DC are both half of that, which is 5 :)

DC = 5

We already know that BC = 13, so we can plug in these values into the pythagorean theorem for the right triangle BDC:

BD^2 + DC^2 = BC^2

BD^2 + 5^2 = 13^2

BD^2 + 25 = 169

BD^2 = 169 - 25 = 144

BD = √144 = 12 :)

Answer:

(6,5)

Step-by-step explanation:

The coordinates of point O are (6, 5) if reflects a line such that N is the reflection of B and O is the reflection of C.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

Reflects a line such that N is the reflection of B and O is the reflection of C.

From Point C, a vertical line should be drawn downward.

Both of these lines will come together at (6, 5). These will be Point O's coordinates.

Thus, the coordinates of point O are (6, 5) if reflects a line such that N is the reflection of B and O is the reflection of C.

Answer:

Step-by-step explanation:

Since the number in question is greater than or equal to 1 but less than

10, we can choose any number between 1 and 10, lets take 3 for example.

If we take the product of 3 and an integer power of 10 number without regard to its sign, this can be expressed mathematically as shown;

[tex]3 * 10^{-5}[/tex] where the power of 10 is -5. Note that any  real number can be used as the power since we are not regarding the sign (Here we used -5). The expression formed according to the expression in question is a SCIENTIFIC NOTATION i.e [tex]3 * 10^{-5}[/tex] gives us a scientific notation.

Scientific notation is a means by which we represent very large or small numbers that are difficult to represent using a decimal notation

Answer:

36°

Step-by-step explanation:

[tex]sector \: \angle = \frac{20}{200} \times 360 \degree \\ \\ = \frac{1}{10} \times 360 \degree \\ \\ = 36 \degree[/tex]

Answer:

1) [tex]5.8\times 10^7\text{ km}[/tex]

2) [tex]2.5\times 10^{-3}\text{ cm}[/tex]

Step-by-step explanation:

To put a value into scientific notation, we need to:

1) Move to decimal place such that our new value is between 1 and 10 and

2) Multiply by 10^n, where n is the amount of spaces moved. If we moved to the left, n is positive. If we move to the right, n is negative.

1)

We have:

[tex]58,000,000[/tex]

We can view this as:

[tex]58,000,000.0[/tex]

Our new value should be between 1 and 10.

58000000

So, let's move our decimal 7 places to the left. This gives us:

[tex]5.8000000[/tex]

Since we moved 7 to the left, we need to multiply by 10^7. Note that the 7 is positive. So:

[tex]=5.8000000\times 10^7[/tex]

We can remove the trailing zeros and add our unit:

[tex]=5.8\times 10^7\text{ km}[/tex]

2)

We have:

[tex]0.0025[/tex]

Our new value should be between 1 and 10. So, move the decimal places 3 units to the right. This yields:

[tex]2.5[/tex]

Since we moved 3 to the right, we need to multiply by 10^(-3). This time, note that our exponent is negative. So:

[tex]=2.5\times 10^{-3}[/tex]

Add our unit:

[tex]=2.5\times 10^{-3}\text{ cm}[/tex]

And we're done!

Step-by-step explanation:

1. 58,000,000 km

2. 0.0025 cm

write in scientific notation:

1)

it would be more easier to read a notation in every 3 decimal places like thousands, millions, billions, etc.

we have 58,000,000 (note where the comma is placed) count every 3 to the left. just multiply by 10^6.

= 58 x 10⁶ km

2) 0.0025 (move 3 decimal places to the right)

= 2.5 x 10⁻³ cm

Answer:

x : y = 9 : 13

Step-by-step explanation:

Given that

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

Express the ratio in fractional form, that is

[tex]\frac{3x-y}{x+2y}[/tex] = [tex]\frac{2}{5}[/tex] ( cross- multiply )

5(3x - y) = 2(x + 2y) ← distribute parenthesis on both sides )

15x - 5y = 2x + 4y ( subtract 2x from both sides )

13x - 5y = 4y ( add 5y to both sides )

13x = 9y ( divide both sides by 13 )

x = [tex]\frac{9}{13}[/tex] y ( divide both sides by y )

[tex]\frac{x}{y}[/tex] = [tex]\frac{9}{13}[/tex] , that is

x : y = 9 : 13

Answer:

[tex]18432\,km/h[/tex]

Step-by-step explanation:

Given: A sound wave travels through iron at a rate of [tex]5120\,m/s[/tex]

To find: rate at which the sound wave travel in [tex]km/h[/tex]

Solution:

Use the following units conversions.

[tex]1\,m=\frac{1}{1000}\,km[/tex]

[tex]1\,s=\frac{1}{3600}\,h[/tex]

Now convert [tex]5120\,m/s[/tex] into [tex]km/h[/tex]

Therefore,

[tex]5120\,m/s=(\frac{5120}{1000})(3600)\\ =512(36)\\=18432\,km/h[/tex]

18432 is the answer

Answer:  13

Step-by-step explanation:

10x+8=12x−18

Step 1: Subtract 12x from both sides.

10x+8−12x=12x−18−12x

−2x+8=−18

Step 2: Subtract 8 from both sides.

−2x+8−8=−18−8

−2x=−26

Step 3: Divide both sides by -2.

−2x - 2

=

−26-2

So , x=13

Answer: [tex]x[/tex] = 13

1. 10[tex]x[/tex] + 8 − 12[tex]x[/tex] = 12[tex]x[/tex] − 18 − 12[tex]x[/tex]

  −2[tex]x[/tex] + 8 = −18

2. −2[tex]x[/tex] + 8 − 8 = −18 − 8

   −2[tex]x[/tex] = −26

3. Split both sides by 2.

Answer:

x = 12

Step-by-step explanation:

Given

5(x - 6) = 2(x + 3) ← distribute parenthesis on both sides

5x - 30 = 2x + 6 ( subtract 2x from both sides )

3x - 30 = 6 ( add 30 to both sides )

3x = 36 ( divide both sides by 3 )

x = 12

Answer:

Part-to-part ratios provide the relationship between two distinct groups. For example, the ratio of men to women is 3 to 5, or the solution contains 3 parts water for every 2 parts alcohol.

Part-to-whole ratios provide the relationship between a particular group and the whole populations (including the particular group). For example, 3/5 of the students in the class are girls, or the mixture is 40% rye grass (40% is equivalent to saying 40 of every 100 parts).
