I would choose a hat, because it is stylish and can keep me warm. My opportunity cost would be a ball, because it is useful for boring, lonely days. This is what I would write, Idk if you like it or not.
Answer:
A=30,32,44,48
B=22,34
intersect=26
numbers going outside is 24,28,36,38,40,42,46
b) 1/14
Step-by-step explanation:
a)The numbers that will go into the A bracket will be 30,32,44 and 48. The numbers that will go into the B bracket will be 22 and 34. The number that will go into the intersect will only be 26. And finally the numbers going on the outside of the venn diagram will be 24,28,36,38,40,42,46.
b)The answer will be 1/14
Answer:
3x + y - 3
Step-by-step explanation:
<u>Like Terms</u>: In algebra, like terms are terms that have the same variables and powers.
To simplify this expression and get an expression that is eual to 5x + 3y - 2x - 2y - 3 I used <em>like terms</em> :
(5x - 2x) + (3y - 2y)
(5x - 2x = <em>3x</em>) + (3y - 2y = <em>1y or y</em>)
3x + y
Then we add the <em>- 3 </em>at the end giving us:
<u><em>3x + y - 3</em></u>
Salt flows in at a rate of
(2 g/L) * (4 L/min) = 8 g/min
and out at a rate of
(<em>B</em>/(200 + <em>t</em>) g/L) * (3 L/min) = 3<em>B</em>/(200 + <em>t</em>) g/min
where <em>B</em> is the amount of salt in the tank at time <em>t</em>.
Then the net rate at which <em>B</em> changes is governed by the ODE,
Multipy both sides by :
Integrate both sides:
The tank starts with 30 g of salt, so <em>B</em>(0) = 30, which gives
