When people buy wood to burn in a stove they purchase it in units of cords (stacks that are 128 cubic feet). Camilla had 3 cords of wood delivered and stacked. She noticed that the people stacking the wood could stack 3/10 of a cord in 2/5 of an hour. (a) Find the unit rate that the water is evaporating at, in terms of inches per hour. (b) If the water evaporates at the rate in (a) for 12 hours, how many inches will evaporate? Express your answer as a mixed number. (a) What is the rate they are stacking the wood in cords per hour? (b) At the rate in (a), how many hours will it take for them to stack all 3 cords?

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
