Answer:
Graph A
Step-by-step explanation:
The graph of a proportional relationship is a straight line through the origin. Only graph A goes through the origin.
Use pythagorean theorem: 6^2+b^2=10^2; 36+b^2+=100; b^2=64;
; b=8cm=EF
Answer:
160 meters
Step-by-step explanation:
Let call dj distance run by Jess and dw distance run by Wes
By Jess courtesy Wes will be 60 meters ahead of Jess
Let call t the time in which both runners are at the same point, which in fact is when both distances are equal
dj = 8 m/sec * t and dw = 60 + 5 m/sec * t
Then we make dj = dw
8*t = 60 + 5*t
3*t = 60
t = 20 sec
Now passed 20 sec dj = 8 * 20 = 160 m
and dw = 60 + 5*20 dw = 160 m
