Answer:

10

Step-by-step explanation:

{14}^{2}  = ( {9}^{2}  +  {x}^{2} )

196 = 81 +  {x}^{2}

196 - 81 =  {x}^{2}

115 =  {x}^{2}

x =  \sqrt{115}

X = 10.7

Please help with the question 2 to 18
vladimir1956 [14]
Since these questions all require similar methods of solving, I will only completely work out the first question of each type.

2. To find \frac{7}{10}as a decimal, all we need to do is complete the fraction by dividing the numerator by the denominator.

\frac{7}{10} = 7 / 10 = 0.7

\frac{7}{10} as a decimal is 0.7.

3. To write a fraction as a percentage, we must first convert it into a decimal, the way we did in problem 2.

\frac{13}{20} =0.65

Then to change that number into a percentage, we can either multiply it by 100, or (my personal shortcut) just shift the decimal point over two places to the right.

0.65 = 65%

which is the answer to question 3.
\frac{13}{20} written as a percent is 65%.

4. Writing a percentage as a fraction is a bit easier than writing a fraction as a percentage. All you need to do is place the percentage in the numerator's place of a fraction with 100 as the denominator and simplify.

2%5 = \frac{25}{100}

Since 25 goes into 100 four times, we can simplify this fraction.

\frac{25}{100} = \frac{1}{4}

which is our answer.

25% written as a fraction is \frac{1}{4}.

5. This is the same as problem 3, so I won't show my work for the sake of time.

\frac{2}{5} as a percentage is 40%.

6. This is the same as problem 1, so I will not show steps again.

\frac{3}{20} as a decimal is 0.15.

7. Done similar problems in past. No work shown.

\frac{21}{50} as a percent is 42%.

8. Same as last problem.

\frac{1}{25} as a percent is 4%.

9. Same as number 4.

 6% as a fraction is \frac{3}{50}.

10. Similar in past.

\frac{3}{5} as a percentage is 60%.

11. Same as 6.

\frac{12}{25} as a decimal is 0.48.

12. Done a lot of these so far.

\frac{3}{10} as a percentage is 30%.

13. Just did one like this.

\frac{3}{4} as a percentage is 75%.

14. Same as 4 and 9.

65% as a fraction is \frac{13}{20}.

15. Plenty of these done in past.

\frac{1}{5} as a percentage is 20%.

16. Last problem, and it's just like the one just before this.

\frac{9}{10} written as a percent is 90%.

So there are the results.
Hope that helped! =)

What is the fourth term of the sequence? <br> a1 = m<br> an = 2an-1<br><br> 2m<br> 4m<br> 6m<br> 8m
harkovskaia [24]

Answer:

8m.

Step-by-step explanation:

an = 2 an-1 means that each term in the sequence( except the first) is obtained by multiplying the last term by 2, so the first 4 terms are m, 2m, 4m, 8m.
