The area of a certain square is 900 square inches. What is the perimeter of this square in inches?
finlep [7]

Answer:

The perimeter of a square with an area of 900 square feet is 120 ft.

Step-by-step explanation:

Calculation of the perimeter of the square:

Since the area is 900 square feet

We know that

The area of square =

So, length of one side should be 30

Now the perimeter should be

= 4(30)

= 120 ft.

Hence, The perimeter of a square with an area of 900 square feet is 120 ft.

What is the value of x? 6.75 + 3/8 x = 13 1/4
wolverine [178]
6.75 + 3x/8 = 13.25
3x/8 =13.25 - 6.75
3x/8 = 6.5
3X = 6.5 x 8
3x = 52
x= 52/3

So your answer would be 52/3 :)

Awarding road contracts. A state Department of Transportation (DOT) recently claimed that each of five bidders received equal co
Sveta_85 [38]

Answer:

a) Hence, the probability of this event occurring if, in fact, the DOT's claim is true

= 3/10 = 0.3

Step-by-step explanation:

a) The concept applied here is combinatorics ; nCr = n!/(n - r)!r!

we are told that out of 5bidders, Three of the bidders were large construction conglomerates

and two were small specialty contractors.

selecting two recipients with tree of the bidders were large construction conglomerates 3C2

= 3!/(3-2)!2!

= 3

Similarly, selecting the two small casualty contractor from the total of 5bidders = 5C2

= 5!/(5-2)!2!

= 10

Hence, the probability of this event occurring if, in fact, the DOT's claim is true

= 3/10 = 0.3

b) if DOTs claim is not true ( probability of failure) = 1 - 0.3

= 0.7 , this value implies that the probability 0.3 is largely compatible and a compliment of the 0.7 and as such it is consistent with the DOTs claim that the selection was random.
