Answer 1
Answer:

Answer:

2 lbs. for $4.50

Step-by-step explanation:

Do a ratio

2 : 4.50

You want to see how much it cost per pound, so divide them by 2

2 ÷ 2 : 4.50 ÷ 2

1 : 2.25

So per pound, the hamburger will cost $ 2.25

________________________________________________________

3 : 6.90

You want to see how much it cost per pound, so all you need to do is divide them by 3

3 ÷ 3 : 6.90 ÷ 3

1 : 2.3

So for the first one, it cost 2.25 per pound, and for the second one, it cost 2.3 per pound....the one that is better will be 2.25 because it cost 5 cents less than the second one

Hope this helped!

Knowing the points A(−5, 2), B(3, 4), C(−4, −3), and D(4, −1), and that segment AB parallel to segment CD, what is the length of segment AB and segment CD, and do points A, B, C, and D form a parallelogram?A) AB=8 and CD=8; therefore, ABCD is a parallelogram
B) AB=2sqrt17 and CD=2sqrt17; therefore, ABCD is a paralleogram
C) AB=4sqrt5 and CD=4sqrt5; therefore, ABCD is a parallelogram
D) AB = 2sqrt17 and CD=4sqrt5; therefore, ABCD is a parallelogram

Answers

I did a graph using the points given, based on what I drew, I choose Choice A.

AB = 8 and CD = 8 ; therefore, ABCD is a parallelogram.

Lines AB and CD are parallel, they both have the same measure which is 8. That is why they form a parallelogram.

Line AC and BD both equal 5.

How do I write a slope intercept form of an equation of a line through given points ?

Answers

you find the slope of the equation using y2-y1/x2-x1 and then you find the y intercept which is the point that crosses the y axis. Then you put that information into the slope intercept equation (y=mx+b   m=slope b=y intercept)


at least i think thats what you are asking
First you need the slope, which is easily attainable by the change of x over the change of y

ex. with coordinates (x,y)(X,Y)

m=slope
m=( rise)/(run)
   =(  change x)/( change of y)
   = (X-x)/(Y-y)

Then you will have every thing except the y intercept
 (represented by b)

Using the slope-intercept form 
and x and y being represented by the x, y values of a co-ordinate

y=mx+b
We can derive b

b= y-mx

Then when we have both m and b
Insert them into the form

ex. if m=-4, b=6

y=-4x+6

Taa daa!

$.46 is what fraction of a dollar

Answers

To find how much .46 is in a fraction of a dollar, all you do is put 46 out of a hundred, to get this:

46/100

So, 46 cents is 46/100 or 46 hundredths of a dollar.

Happy to help you!

46 is a fraction of 100 because since there is 100 pennies in 1 dollar, then the fraction can be labeled like this:

46/100
