Step-by-step explanation:

at a concert, the number of security guards needed is based on the average density of people in an area of 25' x 25'called a block. The concert space measures 350' by 200'. The number of security guards is based on a number of blocks necessary and each security guard can only be responsible for one block. 12,000 people are expected to attend the concert. How many security guards will be needed? How many people, rounded to the nearest 10, will be in each block?

Answers

1 block = 25' x 25' = 625’

Concert space = 70,000’

1 security guard per block

70,00’/625’ = 112’ = number of security guards

12000*625 = 7,500,000’

7,500,000’/7000 = 1071.43 or 1070 people can fit into the block

What is 16.403 round to the nearest tenth?

Answers

Well, since there is a 0 in the hundredths place, the 4 in the tenths place would stay the same! Ignore the 3.
Your answer:16.4
I hope this helps!

16.4 is 16.403 rounded to the nearest tenth because tenths are the number right after the decimal point and if the number right after it is 5 or above you round the place above up. If the tenths are below 5 you round down.

Someone please help me graph! And I can someone please give me the 5 short answers at the bottom ?

Answers

y = (2/3)x - 1/3
y + 1/3 = (2/3)x
(3/2)*(y+1/3) = x
(3/2)y + 1/2 = x

f^-1(x) = (3/2)x + 1/2
This is the inverse you need to graph.  You can plot this yourself, or use a graphing calculator.

The domain of f^-1(x) is all real numbers
The range of f^-1(x) is all real numbers

For the next 2, just plug in the values and solve:

f(2) = 1
f^-1(-19) = -28

Tyler returned $500 worth of merchandise within the discount period. The entry to record the return would be placed into what account?

Answers

Tyler purchased something on account. I'm using the gross method of recording.

1) Purchases  xx
         Accounts Payable       xx

2) Return of merchandise w/in discount period
 
     Accounts Payable   500
                  Purchases         500

3) Payment of remaining merchandise w/in discount period
      Accounts Payable  xx
                     Cash                             xx
                     Purchase discounts   xx

Merchandise that can be discounted but returned w/in the discount period should be recorded with its original value.
The answer to your question is "Debit Accounts Payable/Suppliers Name for $500; credit Purchases Returns and Allowances for $500."
