Divide 8 by 9
8 / 9 = 0.888
0.88 is greater than 0.60 so it is not between 0.45 - 0.60
My understanding it would be letter ( i ) because it is imaginary.
Answer:
H=8
Step-by-step explanation:
12.2H-7.15=90.45
12.2H=90.45+7.15
12.2H=97.6
H=8
Answer:
Part a) 
Part b) 
Step-by-step explanation:
Part a) Write an equation for T (d)
Let
d ----> the number of days
T ---> the time in minutes of the treadmill
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
The slope or unit rate is

The y-intercept or initial value is

substitute

Part b) Find T (6), the minutes he will spend on the treadmill on day 6
For d=6
substitute in the equation and solve for T
