Answer:
The answer to your question is 9
Step-by-step explanation:
Data
Paramecium's length = 4.2 x 10⁻⁴ m
Ant's length = 3.8 x 10⁻³ m
Process
If we need to know how much longer is the ant than the paramecium, we just need to divide the ant's length by the paramecium's length.
Times that the length of the ant is longer than the paramecium length =

Answer:
y = 3.584
Step-by-step explanation:
Given
Variation = Inverse Proportional
When y = 7, x = 4
Required
Find y when x = 5
First, we need to represent the variation.
y varies inversely proportional to x³
This implies that
y ~ 1/x³
Convert variation to equation
y = k/x³
Make k the subject
k = x³y
When y = 7, x = 4
This gives:
k = 4³ * 7
k = 64 * 7
k = 448
To determine the value of y when x = 5;
We make use of y = k/x³
Substitute 5 for x and 448 for k
y = 448/5³
y = 448/125
y = 3.584
