<span>The correct answer is: 800
Explanation:
If the threatre holds 1200 people, it means that there are total 1200 seats in the theatre.
2/3 of the total seats are sold; mathematically we can write it as:
(Total-number-of-seats) * (Fraction-of-seats-sold)
1200 * 2/3 = 800
Hence there are 800 tickets are sold.</span>
60 x 5 = 300 days
So five half-lifes = 300 days
Starting amount = 500mg
<span>Amount after 1st half-life = 250 mg</span>
<span>Amount after 2nd half-life = 125 mg</span>
<span>Amount after 3rd half-life = 62.5 mg</span>
<span>Amount after 4th half-life = 31.25 mg</span>
<span>Amount after 5th half-life = 15.625 mg</span>
<span>Hence after 300 days, the amount of iodine-125 will be 15.625 mg out of 500 mg.</span>

Answer: 615.4mm cube
Step-by-step explanation:
The volume of a cylinder is given as πr^2h
where r= radius
h = height
π = 3.14
From the question, diameter is 14mm and height is 4mm.
To get the radius, we divide the diameter by 2 which will give:
= 14mm/2 = 7mm
Volume= πr^2h
= 3.14 × 7^2 × 4
= 3.14 × 49 × 4
= 615.4mm cube
The volume of the cylindrical barrel is 615.4mm cube.
Answer:
yes
