The amount of matter an object has is called it's mass.
Mass does not depend on gravity, so the mass ALWAYS stays the same.
So 1/12 of all dogs are in hound
of the hound gropu, 3/10 is english foxhounds
find what fraciton of all adogs are english foxhounds
so 3/10 of 1/12
in math 'of' means multiply with fractions so
3/10 times 1/12=(3 times 1)/(10 times 12)=3/120=1/40
1/40 of the dogs were english foxhounds
Answer:
I think acute angle
hope it will helpful to you
You can write this ratio in two other ways:
7 to 13
7 : 13
What you don't want is the value of r(t) becoming negative. Surely that would represent water escaping the reservoir.
How big can (t) get before water actually starts escaping the reservoir?
Essentially, to figure this out r(t) would have to be equal to 0.
700 - 40t = 0
40t=700
t=700/40=17.5
So the first answer is 17.5 seconds. After this amount of time has elapsed the reservoir will start to lose water as r(t) would become negative.
---------------
The reservoir had the least amount of water in it before it was being filled. That was when t=0. The volume of water in the reservoir wasn't negatively impacted as not enough water had escaped it during the 17.5 to 30 second period.
