Answer:

Percentage error = 25 %

Step-by-step explanation:

Given  : Roger has a nail that is 12 centimeters long. He measures and records the length of the nail as 15 centimeters.

To find : What is the percent error in Roger's measurement?

Solution : We have given that

Length of roger nail = 12 cm.

He measures length =  15 cm.

Error = 15 cm - 12 cm.

Error in length =  3 cm .

Percentage error = \frac{Measured-exact}{exact}*100.

Percentage error = \frac{15- 12}{12}*100.

Percentage error = \frac{3}{12}*100.

Percentage error = 25 %

Therefore, Percentage error = 25 %

Alina is able to swim at a rate of about 2.5 miles per hour. Talia is able to swim at a rate of 1.8 meters per second. Which sta
kirza4 [7]

Remark

Without being given choices, we can get answers but they may not be listed among your. The important think is to be working in the same units

Convert miles/hour to m/sec

\frac{2.5 mi}{h}*\frac{1 h}{3600 sec}*\frac{1.6 km}{1 mi}*\frac{1000 m}{1 km}

Now just multiply all the numerators together and divide by all the denominators.

<em><u>Numerators:</u></em> 2.5 * 1.6 * 1000 = 4000

<em><u>Denominators:</u></em> 3600

numerator/denominator = 4000/3600 m/s = 1.111 m/s

Conclusion

Talia is a much faster swimmer than Alina because 1.8 is greater than 1.11. Both numbers are in m/s.

2.5 miles / hour = 1.
