Answer:
The tank must remain intact for 1183 years.
Step-by-step explanation:
Exponential equation for decay:
The amount of a substance after t years is given by:
In which A(0) is the initial amount and r is the decay rate.
A storage tank contains a liquid radioactive element with a half-life of 96 years.
This means that 
, and we use this to find r.
So
It will be relatively safe for the contents to leak from the tank when 0.02% of the radioactive element remains. How long must the tank remain intact for this storage procedure to be safe?
This is t for which 
. So
The tank must remain intact for 1183 years.
Answer:
The answer is B.
Step-by-step explanation:
The tank initially had 1,200 gallons of water, which is leaking at the rate of 2.5 gallons per hour.
Answer:
The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon. ... Magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave.

Answer:
$0.23
Step-by-step explanation:
Theres 16 ounces in a pound. 16-1.7=14.3
divide $3.31 by 14.3
0.23
Tan(x)= 33/105
x = arctan(33/105)
x = 17.44718842 degrees.
