21) The table shows a proportional relationship between x and y, What is the unit rate of y per x?
A) 1
B) 3
C) 6
D) 9

Step-by-step explanation:

the unit rate of y per x :

9/3 = 18/6 = 27/9 = 36/12

all the results = 3

the right answer is B) 3

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
