30% of 40 is equal to 30 X 40 / 100 = 12 25% of 20 is equal to 25 X 20 / 100 = 5 answer together is 30X40+25X20 / 100 = 17
the number = 20 Let N = the number 30% of N = 15% of 40 30% * N = 15% * 40 0.30N = 0.15* 40 0.30N/0.30 = 6/0.30 N = 20
20% first day, 40% second day, Total percent of rain over the two days is (20+40)/2 = 30% per day
40% = 400
40 - 20 percent = 820% of 40= 20% * 40= 20%/100% * 40= 8
40 (+20, -10, +30 ,-20)
it will be (30*300/100)-(40*400/100)+(50*500/100)=500. hope it will help.
well... 10 percent of 400 is 400 divided by 10, which is 40. times 40 by 2 (as 10 times 2 is 20) which is 80.Basically the answer is 80.get it? got it? GOOD!
10% = $40
(0.3 x 40) + (0.25 x 20) = 17
12 and 5
30% of 40 is equal to 30 X 40 / 100 = 12 25% of 20 is equal to 25 X 20 / 100 = 5 answer together is 30X40+25X20 / 100 = 17
40% of 400 = 400*40/100 = 160
the number = 20 Let N = the number 30% of N = 15% of 40 30% * N = 15% * 40 0.30N = 0.15* 40 0.30N/0.30 = 6/0.30 N = 20
20% first day, 40% second day, Total percent of rain over the two days is (20+40)/2 = 30% per day
12 and 5 respectively
20/0.5 = 40 x 0.75 = 30 Seventy-five percent of the number is therefore 30.
