Two gardens are being fenced in. Both gardens will require the same amount of fencing (both gardens have the same perimeter in

Tresset [83]

Answer:

Dimensions of the square garden = 9 meters by 9 meters

Dimensions of the triangular garden = 12 meters

Step-by-step explanation:

Let the measure of a side of the square garden = x meters

Perimeter of the square = 4x meters

Since each side of the triangle is 3 meters longer than each side of the square, side of the triangle will measure = (x + 3)

Perimeter of the equilateral triangle = 3(x + 3) meters

Perimeter of the square = perimeter of equilateral triangle

4x = 3(x + 3)

4x = 3x + 9

4x - 3x = 9

x = 9 meters

Dimensions of the square garden = 9 meters by 9 meters

Dimensions of the triangular garden = 12 meters

The vertex of this parabola is at (3,5) when the y-value is 6 the x value -1 what is the coefficient of the squared term in the

ale4655 [162]

Answer:

1/16

Step-by-step explanation:

Here,

Vertex =(3,5)

x= -1, y=6

Simply,eqn of parabola is given by ax^2+bx+c=y

So, coefficient of squared term (x^2) is 'a'

Therefore, we've to find the value of a

Moving on to solution:

a-b+c=6 ___(i) (by putting the given values of x and y in eqn of parabola )

We know that,

Vetex=(-b/2a, ( 4ac-b^2)/4a)

(3,5) = (-b/2a , (4ac-b^2)/4a)

Equating corresponding sides,we get

3= -b/2a

b=-6a___(ii)

Again,

5=(4ac-b^2)/4a

5=(4ac/4a) - (b^2/4a)

5= c- (36a^2/4a) (by putting value of b from eqn ii )

5= c-9a___(iii)

Now,moving back to the first eqn

a+6a+5+9a=6

16a=1

therefore,a=1/16

Hence ,the required value of coefficient of squared term is 1/16.

I tried my best to give clear explanation as much as I know. It's just we've have to find the value of a . For that, you can use any method you find easier.

Need help on question please!

Bogdan [553]

Answer:

Bart lives 9 1/6 miles from Quickie Mart.

Step-by-step explanation:

So, 2.5 is equal to 2 1/2.

So first turn each mixed number into a improper fraction.

3 2/3 becomes 11/3 and 2 1/2 becomes 5/2.

11/3 * 5/2 = 55/6

55/6 is simplified to become 9 1/6
