The equation 60 = 90e-0.025t can be solved to determine the amount of time needed for a bowl of soup to cool to a temperature safe for a child to comfortably eat. How much time, t, is needed for the soup to cool to a safe eating temperature?

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

78.59 is the mean

step-by-step explanation:

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
