The model shows 1 over 2. Rectangle model divided into two equal sections, first section is labeled one one-half and shaded in.

Which of the following correctly models and gives the quotient of 1 over 2 divided by 3 over 10?
Rectangle model divided into ten equal sections, first three sections are labeled three-tenths and colored dark, the next two sections are colored light to complete one-half, model equals one and two-thirds.
Rectangle model divided into twenty equal sections, first three sections are labeled three-tenths and colored dark, the next seven sections are colored light to complete one-half, model equals three and one-tenth.
Rectangle model divided into twenty equal sections, first three sections are labeled three-tenths and colored dark, the next seven sections are colored light to complete one-half, model equals three and one-third.
Rectangle model divided into ten equal sections, first section is labeled three-tenths and colored dark, the next four sections are colored light to complete one-half, model equals five. + look at link

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

-3

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
