5 (+5=) 10 (+6=) 16 (+7=) 23 (+8=) 31 (+9=) 40 (+10=) 50
The incorrect number is 42. It should be 40.
31. 5 = 1+4 10 = 5+5 16 = 10+6 23 = 16+7 31 = 23+8 Next number will be 31+9 = 40. After that, 40+10 = 50.
If you got 7 out of 23 wrong, you answered 16 questions correctly. To find your percentage score, divide the number of correct answers (16) by the total number of questions (23) and then multiply by 100. This results in approximately 69.57%, meaning you scored around 70%.
18, 23, 10, 39, 22, 17, 16, 15 Mean = (18 + 23 + 10 + 39 + 22 + 17 + 16 + 15)/8 = 20 Lowest Number in set is 10 Highest Number in set is 39 Range = (39 - 10) = 29
8/5 + 7/10 = 16/10 + 7/10 = 23/10 = 23/10
The pattern is +5, +6, +7, so the next number will be 23 + 8 or 31.
The number 23 is 10111 in binary. The digits in a binary number are exponents of 2 rather than 10, so that for a five digit number in binary, the digit places represent 16, 8, 4, 2, 1 instead of increasing values of 10. 10111 = 16+0+4+2+1 = 23
23/10 = 23/10.
23/10 = 23/10
23 over 10 in mixed number form = 23/10
= (60 / 10) + 2(16 - 23) = 6 + 2(16-23) = 6 + 32 - 46 = -8
To find 16 percent of a number, multiply the number by 0.16. In this instance, 0.16 x 23 = 3.68. Therefore, 16 percent of 23 is equal to 3.68.
The molar mass of sulfur is 32.06 g/mol. To find the mass of 6.02 x 10^23 atoms of sulfur, first calculate the number of moles by dividing the number of atoms by Avogadro's number (6.02 x 10^23 atoms/mol). Then, multiply the number of moles by the molar mass of sulfur to get the mass in grams.
