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?

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 do you need me to answer?

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
