Most paper is cut to internationally agreed sizes: A0, A1, A2, ...A7 with the property that the A1 sheet is half the size of the AO sheet and has the same
shape as the AO sheet, the A2 sheet is half the size of the A1 sheet and has
the same shape and so on.

Explain what it means that all sheets have the same shape.​

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

i think the correct option is the second option.
