A rectangular billboard is 9.35 meters wide and 6.82 meters tall what is the perimeter of the billboard in meters?

kati45 [8]

-The perimeter is the length of the line if the whole rectangle was straightened out.
-a rectangle has 2 sets of 2 even sides. The top and bottom width would be equal and the two heights would be equal

Armed with these two facts we know the perimeter would be Side A + Side B + Side C + Side D
9.35 + 9.35 + 6.82 + 6.82 = ?

The actual formula for a rectangle or even a square is
2(length + width)

How many ways are there for six dogs and four cats to sit in a row in a strawberry field so that no two cats sit next to each ot

pickupchik [31]

Answer: 5,760

Step-by-step explanation:

$\\$ It was given that each dog is distinct from other dogs and each cat is distinct from other cats, Also from the hint given, the First position is for the dogs. $\\$ Let D represent the dogs and C represent the Cat , then we have

$\\$ D C D C D C D C D D or

$\\$ D D C D C D C D C D or

$\\$ D C DD C D C D C D or

$\\$ D C D C D D C D C D or

$\\$ D C D C D C DD C D

$\\$ Each of the arrangements above could be done in

$\\$ 2 x 4! x 4! ( it is constant that D is starting , so I am only left with the arrangement of the remaining 5 D's , out of the remaining 5 D's it is also constant that tow of them will be together and this could be done in 2 ways, so I have 4! left for the D's and 4! also for the C's )

$\\$ = 2 x 24 x 24

$\\$ = 1 , 152

$\\$ The total arrangement = 5 x 1 , 152

$\\$ = 5,7 60 ways

Luis has 5 cans of soda. He will buy more cans of soda from the store. The store has 12 cases in stock and each case contains 24

-BARSIC- [3]

We are given function f(c) = 24c+5 that models the number of cans Luis will have after his purchase of more c number of cases Luis purchase.

We need to find the domain of the function in respect to the given function.

Here we used variable c. And c represents the number of cases Luis can purchase.

Minimum number of cases Luis can purchase = 0.

There are total 12 cases in stock.

Therefore, maximum number of cases Luis can purchase = 12.

<h3>So, the domain of the function is {0,1,2,3,4,5,6,7,8,9,10,11,12}.</h3>
