Step-by-step explanation:
- here is the anewer then change in fraction
First you need the midpoint formula. (x1+x2 divided by 2)and (y1+y2 divided by 2) Which would look like this.. 13+-6=7 and 7 divided by 2 is 3.5.... 8+-6=2 And 2 divided by 2 is 1. so your answer is (3.5, 1)
Answer:
a. 25.9% b. $.76 per pound
Step-by-step explanation:
For part a. the formula for percent decrease is
% dec = 
We are solving for % dec. Filling in:
% dec =
simplifies to
% dec =
which gives us, rounded to one decimal place:
% dec = 25.9%
For part b. we are going to use that percent decrease and fit it into a new equation to solve for the new price of tomatoes when we know the original price. Filling in:
which could be written instead as

Now you can see what will happen on the right when we divide by 100...they cancel out. That looks like this, when we divide both sides by 100, as we must because this is an equation:

Simplifying on both sides:

Now we will multiply both sides by 1.03:
.26677 = 1.03 - new and
-.76323 = -new so
the new price is .76 per pound
Skateboard: $60.00
Equipment only: $1.50
Skateboard + Equipment: $5.50
In this case, you would take the cost of the skateboard: $60 and divide $5.50 (all items) to get the number of hours.
Which would be "10.9090"... If we round it we get 11 hours...
This should be correct. <3
