Apr 11, 2018 · See below: >Finding 1/10 of a number is the same as dividing it by 10. To find a tenth of something simply multiply it by 1/10 and then simplify. That will be a tenth of it: What is 1/10 of 20? 20 can be put over 1, since anything divided by 1 is itself. So do that and multiply: 1/10 xx 20/1 rarr 20/10 rarr 2 Here are a couple more examples: What is 1/10 of 45? 1/10 xx …

Aug 6, 2018 · Convert it into a decimal 1/10=0.1 Change a decimal to a percentage by multiplying by 100 0.1=10% so 1/10=10%

Oct 10, 2015 · It will be easier for you to see if you first write it as a rational number, then as a decimal number. 10^-6 means we take 6th power of 10, then take the reciprocal of it. 6th power of 10 is 1000000, and reciprocal of it is 1/1000000 If we write it as a decimal number, the answer would be 0,000001

Jun 7, 2018 · 0.001 through rewriting the expression in scientific notation We can rewrite the expression as 1*10^-3 This is in scientific notation. Since we have a negative exponent, we loop the decimal three times to the left. We get 0.001 Hope this helps!

Oct 14, 2015 · This is a trick question: a bat and a ball cost $1.10 together. If the bat costs $1 more than the ball, then how much does the ball cost?

Conjugate acids and conjugate bases are the acids and bases that lose or gain protons. NH4+ is the conjugate acid to the base NH3, because NH3 gained a hydrogen ion to form NH4+.The conjugate base of an acid is formed when the acid donates a proton.

Mar 22, 2014 · You divide the final volume by the initial volume. "DF" = V_f/V_i EXAMPLE 1: What is the dilution factor if you add a 0.1 mL aliquot of a specimen to 9.9 mL of diluent?

Feb 8, 2017 · a_n = 1/2n(n+1) These are recognisable as triangular numbers, but let's use a general method for finding matching polynomial formulas...

May 2, 2016 · 5 cents If the ball costs x cents, then the bat costs 100 + x cents and the total is 100+x+x = 100+2x cents. We are told that the total is 110 cents, so 2x = 110 - 100 = 10 and hence x=5. Footnote Though this is not a difficult algebra question, it seems very intriguing psychologically. I find myself wanting to say the bat cost $1.00 and the ball $0.10. I think part …
