-Dominant- [34]
Hi there!

To get the answer to this question, let's divide the diameter of the Earth by the diameter of Mercury.

\frac{1.3*10^4}{4.9*10^3}

We can change this to

\frac{1.3}{4.9}*\frac{10^4}{10^3}

Let's solve for each individual fraction

\frac{1.3}{4.9} ≈ 0.27

\frac{10^4}{10^3} = 10

Now, multiply.

0.27 * 10 = 2.7

That's your answer.

Have an awesome day/night! :)

The perimeter of a rectangle is 66 cm.if the width of the rectangle is three more than half the length,find the length of the re
hoa [83]
<span>Let us use the variable x for length. So width will be 1/2x + 3. Perimeter = x+x+ 1/2x + 3 +1/2x + 3 = 3x + 6 = 66 Therefore 3x = 66-6 = 60 So x = 60/3 = 20 The length is 20 cm. Therefore the width = 1/2 of 20 + 3 = 10 + 3 = 13 cm Check: 20+20+13+13 = 66</span>
