11m
The area of a triangle is bh/2. If we know the height (8m), we can plug it into a=bh/2 for a=8h/2 or a=4h or a/4=h
Since we know the area (44m^2), we can put that in for 44/4=h or h=11 metres.
Answer:
Marty's function has larger slope as compared to Ethan's slope.
Step-by-step explanation:
Marty function:
y plus 3 equals StartFraction 1 Over 3 EndFraction left-parenthesis x plus 9 right-parenthesis.
Writing in mathematical form: 
Marty has written expression in point-slope form:
where m is slope
So, comparing Marty's equation with general point-slope form equation we get slope 
Now, Ethan has a table
x y
-4 9.2
-2 9.6
0 10
2 10.4
We can find slope using formula: 
Using any two points, we can find slope of Ethan's equation

So, we get Marty's slope = 0.3
Ethan's slope = 0.2
So, Marty's function has larger slope as 0.3 is greater than 0.2
Y=.3x+25(z) z= number of days
y=.3(50)+25(1)
y=15+25
y=40
3/4 is .75
There are 60 minutes in an hour
Multiply .75 by 60 to get 45 minutes
