If 5 liters cost $2.50, then how much would it cost for 9 liters?
damaskus [11]

5:$2.50

9:?

divide 5 by both sides cause you wanna see how much is 1 liter so you can multiply that with 9.

5 divided by 5 is 1.

$2.50 divided by 5 is $0.50

1:$0.50

each liter costs  $0.50

Multiply $0.50 with 9 and that is $4.50

you work for a telecommunications company and need to analyze the outcome of a proposed new cell tower project. cell phone radio
umka21 [38]

Answer:

The equations describing the area which each tower covers are given as

Tower A : x^{2} + y^{2} = 16

Tower B : (x - 5)^{2} + (y - 4)^{2} = 9

Tower C : (x - 4)^{2} + (y + 4)^{2} = 25

Step-by-step solution:

Cell phone radio towers broadcast a cell phone signal in circular pattern

Tower A at Adele Acres have position co-ordinates  as (0,0) and a coverage radius of  4 ml. So, the area which it covers is given by the equation,

x^{2} + y^{2} = 16 -------------------------------(1)

Tower B at Brown Lake have position co-ordinates  as (5,4) and a coverage radius of  3 ml. So, the area which it covers is given by the equation,

(x - 5)^{2} + (y - 4)^{2} = 9 -------------------------------(2)

Tower C at Cady City have position co-ordinates  as (4,-4) and a coverage radius of  5 ml. So, the area which it covers is given by the equation,

(x - 4)^{2} + (y + 4)^{2} = 25 -------------------------------(2)

There are 20 entries in the chess tournament. How many ways can they finish in first, second,
Romashka [77]

Answer:

6840

Step-by-step explanation:

Here, the order matters (1st, 2nd, and 3rd), so we need to use permutations.

There are 20 people who can get in first place.  After that, there are 19 people who can get in second place.  Finally, there are 18 people who can get in third place.  So:

20 * 19 * 18 = 6840
