Answer:
I'm having a hard time with this, I keep confusing myself but hopefully this example will help at least to get an idea:
"12 cm
Explanation:
We're pouring 12 litres of water into a container that is 40cm long and 25cm wide. Let's see how big the bottom of the container is:
40cm×25cm=1000cm2
1 litre of water fills 1000cm3, and so it would rise 1 cm (we divide the volume of the water by the surface area to arrive at the height):
1000cm31000cm2=1cm
12 litres of water can then be seen to rise 12 cm:
12×1000cm31000cm2=12cm"
Answer:adult=75
Students = 200
Children=75
Step-by-step explanation:
Let x= adult tickets, y=students, z=child
x+y+z =350
Since x=z
y+2z= 350 -----------1
20x +12y + 10z = 4650
Since y=z
12y +30z = 4650 --------2
Using elimination method to solve eqn 1&2
Multiply eqn 1 by 12
12y + 24z = 4200
12y +30z = 4650
Subtract equ 2 from 1
-6z =-450
z=75, x = 75
y=350 -(75+75)
y= 200 tickets
The answer is the 4th or 119
£42 i’m sorry i just need to ask a question but it won’t let me if i don’t answer one so hey
