x = 6
Step-by-step explanation:
<em>This can be written as a ratio</em>
7 : 2
21 : x
<em>If you times one side by 3, you have to multiply the other side by three too:</em>
2 × 3 = 6
∴ x = 6 when y = 21
Answer:
4

Answer:
<h3> 78%</h3>
Step-by-step explanation:
Given
Number of scientist that line in Antarctica during the winter = 1,100
Amount of scientist in the summer = 5,000
Increment = 5000 - 1100
Increment = 3900
percentage change = Increment/Original amount * 100
Percentage change = 3900/5000 * 100
Percentage change = 3900/50
Percentage change = 78%
<em>Hence the percent change in the number of scientists living in Antarctica is 78%</em>
