Answer:

1 light year \approx 6.02 \times 10^4 astronomical unit

Step-by-step explanation:

ratio

$=\frac{9.5 \times 10^{12}}{1.5 \times 10^8}\\=\frac{19}{3} \times 10^{12-8}\\\approx 6.01666 \times 10^4 \\\approx 6.02 \times 10^4$

Whats the answer to this question plz work it out

IrinaVladis [17]

This is very easy. 5 - 1 is 4. Take one away to reserve for the fraction. 9 - 4 = 5. 1 = 6/6. 6/6 = 4/6 is 2/6 or 1/3. It is 5 2/6 or 5 1/3

Solve for x.

Afina-wow [57]

X = 18

Steps:

Remove the parenthesis...

4x-6+x = 12+4x

Then cancel out 4x...

-6+x = 12

Then regroup the terms...

x - 6 = 12

Add 6 to both sides...

x = 12 + 6

Then you get...

x = 18

I need help on ratio of x-coordinates and ratio of y-coordinates

ad-work [718]

Answer:

Ratio of x-coordinates:

$\frac{-1}{-2}=\frac{1}{2}$

$\frac{2}{4}=\frac{1}{2}$

$\frac{-2}{-4}=\frac{1}{2}$

Ration of y-coordinates:

$\frac{2.5}{5}=\frac{1}{2}$

$\frac{1}{2}=\frac{1}{2}$

$\frac{-2}{-4}=\frac{1}{2}$

Step-by-step explanation:

The table is asking for the ratio of x-coordinates for each point (A, B, C and D) for both the image and pre-image. The ratio is the image 'x' or 'y' value ÷ the pre-image 'x' or 'y' value. Each ratio should be expressed in simplest form and should show the same pattern of dilation, or same scale factor. In this case, the second figure is 1/2 the size of the original figure.
