Answer:
3.6 hours or 3 hours and 36 minutes.
Step-by-step explanation:
If the first pipe can fill the pool in 9 hours that means that in 1 hour it fills 
of the pool, we use the same logic for the second pipe and conclude that in 1 hour it feels up 
of the pool. If both were to fill the pool together that means that in 1 hour they would fill...
of the pool in 1 hour.
Now to find how many hours it will take divide the pool by the speed with which it is getting filled.
hours
3.6 hours in other words is 3 hours and 36 minutes.
Answer:
0.88m²
Step-by-step explanation:
Area of a trapezium = 1/2(a+b)h
a and b are the parallel sides
h is the height
Given
a = 1m
b = 1.2m
h = 0.8m
Substitute
Area of the trapezium = 1/2(1+1.2)(0.8)
Area of the trapezium = 1/2(2.2)(0.8)
Area of the trapezium = 1.1 * 0.8
Area of the trapezium = 0.88m²
Mei has 8 jars and each is 300ml
so she will need to times 8 by 300ml = 2400ml.
She needs a pot that holds 2400ml at least
(Actually, she needs a bigger pot because it needs to hold 2400ml so if the pot is that size the liquid will spill)
