Which situation represents a proportional relationship between the number of laps run by each student and their time. desmond's time (s) 146 292 584laps 2 4 8maria's time (s) 150 320 580laps 2 4 6?

Desmond's time

Step-by-step explanation:

Given,

Desmond's time (s)    146      292      584

laps                               2        4           8

Maria's time (s)          150      320      580

laps                               2         4       6

By the first table,

Thus, the situation of Desmond shows the proportional relationship between time and number of laps,

By the second table,

Thus, the situation of Maria does not show the proportional relationship between time and laps.

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3
