Other leg^ 2 = 20^2 - 12^2
other leg^ 2 = 400-144 = 256
then other leg = √256 = 16
The distance traveled by Mr.Nersin = 4 miles
The time for which Mr.Nersin rode first = 1/2 hour
The time for which Mr.Nersin rode after a short rest = 1/10 hour
Then
The total time for which Mr.Nersin rode = (1/2) + (1/10) hour
= (5 + 1)/10 hour
= 6/10 hour
= 3/5 hour
So
Average speed of Mr. Nersin = Distance traveled / Time taken
= 4/(3/5) miles/hour
= (4 * 5)/3 miles/hour
= 20/3 miles/hour
= 6 2/3 miles/hour
= 6.67 miles per hour
So the average speed at which Mr.Nersin traveled is 6 2/3 or 6.67 miles per hour.
Answer:
40%
Step-by-step explanation:
2/5 as a decimal is 0.4, and 0.4 as a percentage is 40% hope this helped!
Answer:B
Step-by-step explanation:
4E and LA are right angles; therefore, these angles are congruent since all right
angles are congruent. Is - 15 over 5 and 12 over 4shows the corresponding sides are proportional;
therefore, ABC ~ AEDC by the SSS Similarity Postulate.
