<h3>
Answer: 50</h3>
==========================================================
Explanation:
We simply multiply the two values given to us
600*(1/12) = 600/12 = 50
We expect about 50 bulbs to be defective.
Note how if we had 50 bad bulbs, then 50/600 = (1*50)/(12*50) = 1/12 of the batch of 600 bulbs is defective.

Answer:
<h2>
The area of the sheet needed is </h2><h2>
3m^2 approx.</h2>
Step-by-step explanation:
Step one:
given
height h= 1m
diameter= 70cm= 0.7m
radius r= d/2= 0.7/2= 0.35m
<em>The surface area or the total surface of a cylinder is equal to the sum of the base area times two and the area of the curved surface.</em>
The formula is
T.S.A.=2πrh+2πr^2
Required is the T.S.A
Step two:
substitute our given data we have
T.S.A.=2*3.142*0.35*1+2*3.142*0.35^2
T.S.A.=2.199+0.769
T.S.A.=2.96m^2
T.S.A.=3m^2 approx.
Answer:
$1.60
Step-by-step explanation:
100% represents the marked price thus
100% + 3.3% = 103.3% represents the purchase price
100% ---------------$1.55
1%--------------$1.55 / 100 = $0.0155
103.3%-------------------$0.0155 x 103.3 = $1.60115
