Step-by-step explanation:
39, 40, 44, 49, 50, 54, 56, 61, 62, 68
39, 40, 44, 49, <u>50, 54,</u> 56, 61, 62, 68

21%
210 is 10.5% of the amount that is for 6 months doubling it will make it 420 that is 21% of the total amount of 2000.
1block=2cm
1cm=10mm
therefore 1block=2×10=20
1000÷20=50
=50blocks
(f-v)/a = t
f = v + at
Subtract v from each side
f-v = v-v + at
f-v = at
Divide each side by a
(f-v)/a = at/a
3/12 really is 1/4 (Divide top and bottom by 3) 3/3 = 1 and 12/3 = 4
1/5 + 1/4 = 4/20 + 5/20 = 9/20
There is something we don't know about this question. If you put a remark, I will come back and look at it.
