B) 64, because all these numbers have a difference of 14, and it you keep going, the 10th term will be 64.
What do u mean I’ll answer I just don’t understand wht u mean
My answer is: P/2a = 2b
if that's wrong then im sorry I got it by dividing 2a on each side so 2b would be alone
Answer:
10%
Step-by-step explanation:
The computation of the percentage of bulbs that switched on incandescent is as follows;
Let us assume the incandescent be I
And, the fluorescent be F
Now the equation is
0.4I + 0.9F = 0.8 (I+F)
0.41I + 0.9F = 0.8I + 0.8F
So here
0.4I = 0.1F
Now the percentage would be for incandescent in the case of switched on is
= 0.4I ÷ 0.8(I+F) × 100
= 0.1F ÷ 1F
= 10%
