Ratio of girls to total number of students: 4:12
Step-by-step explanation:
There are four girls, and eight boys.
In all there are 12 students.
So the ratio of girls to total number of students taking swimming lessons is 4:12
Fatima's claim that she has 0.413 kilogram of rose petals left is wrong
<h3>How to determine the amount of rose petals left?</h3>
The given parameters are:
- Amount purchased = 0.454 kg and 0.056 kg
- Used amounts = 0.02kg and 0.095 kg
The amount left is the difference between the amount purchased and the amount used.
So, we have:
Remaining = 0.454 + 0.056 - 0.02 - 0.095
Evaluate
Remaining = 0.395
This means that the remaining amount is 0.395kg, not 0.413 kg
Hence, Fatima's claim that she has 0.413 kilogram of rose petals left is wrong

<span>V(o) = 1/3 πr²h - old volume
</span>V(n) = 1/3 π(2r)²(h/2)=1/3 π(2r)²(h/2)=1/3*4/2* πr²h=1/3*2* πr²h
V(n)/V(o)=1/3*2* πr²h/1/3 πr²h=2/1
V(n)/V(o)=2/1 - ratio
the volume will be doubled
