She has to walk 60 minutes more to reach her goal.
Given: Flo sets a goal of walking 12,000 total steps per day. Flo's normal routine involves walking 6,000 steps per day.
To find: To Determine how many extra minutes should she walk per day beyond her normal routine?
Formula: Number of extra minutes = she walks per day beyond her normal routine / number of steps per minute
flo's normal routine involves walking steps per day= 6,000
If flo walks 100 steps per minute:
she walks per day beyond her normal routine = 
= 
Extra minutes = 
= 60 minutes
Therefore, she has to walk 60 minutes more to reach her goal.

Answer:
24 feet
Step-by-step explanation:
First, I used the proportion method to set up the numbers. I used x for the height of the tree.
x/45 = 6/11.25
Notice that the x and the 6 are both the heights of the tree and Dimitri and that they are both on the top of the fractions.
45 and 11.25 are the lengths of the shadows and they are both on the bottom of the fractions.
Next, I did 6 times 45 and got 270. Then I did 270 divided by 11.25 and got 24.
You're welcome! :)
Answer:
You sold 20 student tickets.
Step-by-step explanation:
Given that:
Total tickets sold = 27
Total amount collected = $170
Cost of student ticket = $5
Cost of adult ticket = $10
Let,
x be the number of students tickets sold
y be the number of adult tickets sold
x+y = 27 Eqn 1
5x+10y=170 Eqn 2
Multiplying Eqn 1 by 10
10(x+y=27)
10x+10y=270 Eqn 3
Subtracting Eqn 2 from Eqn 3
(10x+10y)-(5x+10y)=270-170
10x+10y-5x-10y=100
5x=100
Dividing both sides by 5

Hence,
You sold 20 student tickets.
First you differentiate to find the gradient
dy/dx = (6 - - 8) / (-4 - 7)
= 14 / -11
= - 14/11
Then you use this formula
y - y1 = m (x - x1)
y1 being the y coordinate
x1 being the x coordinate
m being the gradient (or slope)
y - 6 = -14/11 (x - - 4)
y - 6 = -14/11x - 56/11
y = -14/11x + 10/11
