The perimeter of a rectangle is 60 m and its length is twice its width. find the length of the rectangle
GREYUIT [131]
Length = 2W

P= 2L + 2W
60 = 2(2W) + 2W
60= 4W +2W
60 = 6W
60/6W = 6W/6W
w = 10
Length = 2(10)
Length = 20

P= 2L + 2W
60= 2(20) + 2(10)
60= 40 +20
60 = 60

Y=x^2+bx+c;(-2,3)
Maksim231197 [3]
<h3>Answer:  b = 4 and c = 7.</h3>

===============================================

Explanation:

Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.

The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.

Plug those three values into the vertex form below

y = a(x-h)^2 + k

y = 1(x-(-2))^2 + 3

y = (x+2)^2 + 3

Then expand everything out and simplify

y = x^2+4x+4 + 3

y = x^2+4x+7

We see that b = 4 and c = 7.

the hypotenuse of a right triangle is 3 cm and one of the legs is 1 cm what is the length of the other leg ?
Afina-wow [57]

Answer:

2\sqrt{2}

Step-by-step explanation:

let the other leg be x

Using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 1² = 3²

x² + 1 = 9 ( subtract 1 from both sides )

x² = 8 ( take the square root of both sides )

x = \sqrt{8}

  = \sqrt{4(2)}

  = \sqrt{4} × \sqrt{2} = 2\sqrt{2} ← exact value

Brenda has 5/6 of a pie to divide evenly amount 4 people. what fraction of a pie does each person get
yulyashka [42]

The fraction of the pie Each person will get from Brenda = ( 5 / 24 ) of the pie.

Given,

Brenda has 5/6 of pie with her.

The total number of persons = 4

Now, the fraction of the whole pie each person will take :-

( Number of pie ) / ( total persons )

= ( 5 / 6) / 4

= ( 5 / ( 6 x 4 ) )

= ( 5 / 24 )

Therefore, the fraction of the pie each person get from Brenda = ( 5 / 24 )
