The number of birds is an illustration of ratio and proportions, and Emma is 5 years old
<h3>How to determine Emma's age?</h3>
From the complete question, Emma's age is the sum of the simplified ratio between the number of birds.
The ratio can be represented as:
Birds = 200 : 300
Simplify the ratio
Birds = 2 : 3
Add the numbers in the above ratio
Emma = 2 + 3
Emma = 5
Hence, Emma is 5 years old

Answer:
13 levels
Step-by-step explanation:
Direct variation can be expressed using the formula:
y = kx, where 'k' is the constant of variation
Since Michael can move up 5 levels in 55 minutes:
n = km, where 'n' is the number of levels and 'm' is the number of minutes:
5 = 55k
k = 1/11
To find the number of levels after 143 minutes:
n = (1/11)(143)
n = 13 levels
