How many decades are there in a millenuim? explain

1 answer:

8 0

A millennium = 1000 years.

A decade =10 years.

So the number of decades in a millennium = 1000 / 10 = 100

So there are 100 decades in a millennium.

Hope this explains it.

A large mixing tank initially contains 1000 gallons of water in which 30 pounds of salt have been dissolved. Another brine solut

serg [7]

Answer:

(B) $\dfrac{dA}{dt}=8-0.004A$

Step-by-step explanation:

Volume of fluid in the tank =1000 gallons

Initial Amount of Salt in the tank, A(0)= 30 pounds

Incoming brine solution of concentration 2 pounds of salt per gallon is pumped in at a rate of 4 gallons per minute.

Rate In=(concentration of salt in inflow)(input rate of brine)

$=(2\frac{lbs}{gal})( 4\frac{gal}{min})=8\frac{lbs}{min}$

The resulting mixture is pumped out at the same rate, therefore:

Rate Out =(concentration of salt in outflow)(output rate of brine)

$=(\frac{A(t)}{1000})( 4\frac{gal}{min})=\frac{A}{250}$

Therefore:

The rate of change of amount of salt in the tank,

$\dfrac{dA}{dt}=$Rate In-Rate out\\\dfrac{dA}{dt}=8-\dfrac{A}{250}\\\dfrac{dA}{dt}=8-0.004A$

Brian made a tasty burger. the diameter of the burger was 5cm. what was the area of burger

Vadim26 [7]

19.625cm squared because you have to divide the diameter by 2 to get the radius.
area of circle=pi times radius times radius
=3.14 times 2.5 times 2.5
=19.625cm squared
