explanation
Step-by-step explanation:
8. well each time, the number is going up by 6 per every 1 right? so the rate would be 1:6 type thing.
10. now this one is going down 1000 every 2 minutes. so the rate would be 2—1000, or 1:-500.
this is just written out ones to make it look like it makes sense...
8. 1 to 6
10. 1 to -500
All this is more or less a proportion type of question.
2/X = 8/64
8/4 = 2
64/4 = 16
The value of X is 16 cubic metres.
Okay, what are you asking?
