Janet jumped 156 in in the long jump competition at the high school track meet her personal record is 13 ft 1 inch Did Janna beat her personal record at the track meet? Explain.

No

Step-by-step explanation:

Based on the information provided within the question, we can make this determination but must first convert both scores into the same unit of measurement. In this case we can convert her old record into inches. Since there are 12 inches in each foot, we can multiply her record by 12 and add the 1 extra inch, like so...

(13 * 12) + 1 = 157 inches

Therefore since here old record was 157 inches, Janet did not beat it with her new score of 156 inches.

what is your question that you ask

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
