Hi there!
To get the answer to this question, let's divide the diameter of the Earth by the diameter of Mercury.
We can change this to
Let's solve for each individual fraction
≈ 0.27
= 10
Now, multiply.
0.27 * 10 = 2.7
That's your answer.
Have an awesome day/night! :)

<u>Answer:</u>
• Equation =
• length = 56 ft
• width = 32 ft
<u>Step-by-step explanation:</u>
The ratio of the length to width is 7:4.
∴
⇒ [Equation 1]
We know that the perimeter of the garden is 176 feet.
∴
⇒
⇒ [From Equation 1]
⇒
⇒
⇒
⇒
We know from Equation 1 that:
∴
⇒
Number of students who have sent a text message only is given by the difference between those that have sent a text message and those that have done both.
i.e. Number of students who has sent a text message only = 58 - 12 = 46
Number of students who have uploaded a selfie only is given by the
difference between those that have uploaded a selfie and those that
have done both.
i.e. Number of students who have uploaded a selfie only = 21 - 12 = 9
The total number of students surveyed is 70.
Let the number of students who have neither sent a text message nor taken a selfie today be x, then
46 + 9 + 12 + x = 70
67 + x = 70
x = 70 - 67 = 3
Therefore, 3 students neither sent a text message nor taken a selfie today.
The number of students that have sent a text message or have taken a selfie today is given by the sum of the number of students that have sent a text message and the number of students that have taken a selfie less the number of people that have done both.
i.e. number of students that have sent a text message or have taken a selfie today = 58 + 21 - 12 = 67.
