Find the value of ( 50 x 1)+(49x2)+(48x3)+(47x4)+....(1x50

Answer 1

your calculator has a percentage button, thecalculation is as follows: 40 x 25% = 10. If yourcalculator does not have a percentage button, you must first divide the percentage by 100: 25 ÷ 100 = 0.25. You can then multiply this answer by the whole to determine the part: 0.25 x 40 = 10.Apr 24, 2018
