73.131

Step-by-step explanation:

T=  

s(s−a)(s−b)(s−c)

​  

T=  

20.9(20.9−15)(20.9−17)(20.9−9.81)

​  

T=  

5348.14

128

Step-by-step explanation:

15 × 17 ÷ 2 = 127.5

Round to 128

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
