B.) , ratio of 20:1C.) , There are 11 costumers per tower and 11000 costumers in total

Step-by-step explanation:

Please mark brainliest...

multiply each value of the C. by 1,000 to get the # of C.s divide the # of C.s / T.s this gives you C.s per T.Convert to ratio formatthere is on average 15 to 20 C.s per T.5250/273 = 14.0756250/325 = 19.2307250/377 = 19.2309250/273 = 19.230    6250  =  y  

             377        572

    2.  multiply both sides by 572

    3. 572 .  6250 = y

                   377

   4. divide known pair

572 x 19.230 = y

   5. solve for y

   6. y = 10999.56

   7. divide y value by 1000

   8. 10.99956

These are linear equations, so there is x and y. On number one the first thing they plotted was (3,8) so in a function table the 3 would be on the left side and the 8 would be on the right side. I’ll leave you with the rule of the first one, if the rule is times 2 plus to the how would you put it in a function table.

The first thing that you would put into the function table on the first question would be as I said earlier 3 and then 8. The rule is the rate. Using a function table will be very helpful (That’s why I keep mentioning one). Let me know if this helps.

5 cookies
1.5 cookies
50 cookies
48 cookies

Answers

Answer:

just do this 24.76min. 23.24 then see what u have got for

Answer:

c - 23.24 = 24.76 (the first option)

48 cookies

Explanation:

Profit is equal to revenue(amount made) minus costs, or r - cost = p. The revenue is 1*cookies sold, or c. So, c - 23.24 = 24.76.

Solving is relatively simple,

c - 23.24 = 24.76

c = 48 (add 23.34 to both sides)
