$25 a lamp
Step-by-step explanation:
First divide $10,000 by 500 lamps to find how much one of them cost

Answer:
1708.58658058
Step-by-step explanation:
Total surface area formula = (π×r²)+(π×r×s)
r = radius
s = slant height
So we substitute the values into the formula (π×r²)+(π×r×s)
(π×14.2²)+(π×14.2×24.1) = 1708.58658058
Answer:
36
Step-by-step explanation:
the first sequence starts
4 12 (3*4) 36 (3*12) 108 (3*36) ...
the second sequence starts
20 28 (8+20) 36 (8+28) 44 (8+36) ...
so, just by writing down a few elements you can see it already.
I knew it already before that just by thinking "the first sequence has only numbers that can be divided by 3. what is the first number of the second sequence that can be also divided by 3 ? oh, yeah, 36 !"
