Answer:
Step-by-step explanation:
First convert km to meters
143000 km = 143,000,000m = 1.43*10^8 m
Now convert 10 billion to scientific notation1 00
10 billion = 1 * 10^10
What this means is that 1 * 10^10 meters in outer space = 1 meter for the scale model.
Now show what the ratio is for
1.43*10^8
======== Divide by the denominator
1 * 10^10
1.43 * 10^(8 - 10)
1.43 * 10 ^ - 2 meters
Answer: 0.0143m or B
<u>Given</u>:
Given that the sides of the shape.
The given shape consists of 8 sides.
We need to determine the perimeter of the given shape.
<u>Perimeter</u>:
The perimeter of the figure can be determined by adding all the lengths of the sides of the shape.
Thus, we have;

Adding the values, we get;

Thus, the perimeter of the given shape is 36 feet.
Answer:
a and d is the correct answer
Step-by-step explanation:
10 + (-5) = 10 - 5 = 5
-11 + 20 = 20 + (-11) = 20 - 11 = 9
102 + (-1) = 102 - 1 = 101
<span>-20 + 60 = 60 + (-20) = 60 - 20 = 40</span>
