Answer: The height is 4.472

Step-by-step explanation: That formula is Heron's formula.

Where "s" is calculated like this:

s = (a + b + c) / 2

In this case:

a = 14

b = 12

c = 6

replacing:

s = (14 + 12 + 6) / 2

s = 16

Now we calculate the area:

A ^ 2 = 16 * (16−14) * (16−12) * (16−6)

A ^ 2 = 1280

A = 35.777

The area of the triangle is:

A = b * h / 2

In this case we will take the base as the longest side of the triangle, that is to say = 14

Thus:

h = A * 2 / b

h = 35.777 * 2/16

h = 4.472

So the height is 4.472

Answer:

y = 4

Step-by-step explanation:

Note that A and B have the same x-coordinate:  1.  This means that AB is a vertical line through x = 1.  The perpendicular bisector of AB must be a horizontal line situated halfway between y = 3 and y = 5.  Thus, it's just y = 4.

Review:  y = 4 bisects AB and represents a horizontal line.

A system of equations is graphed on the coordinate plane.
ANTONII [103]
You have 2y=3x-1 and 4y=6x-2. first step is to get the y by itself . first equation you divide everything by 2 which gives you the equation: y= 3/2x-1/2
or y= 1.5x-.5, for the second equation you divide everything by 4, which gives you y=6/4x-2/4 (1/2) or y=1.5-.5. both equations are equal to one another: 
the answer is therefore C Infinitely many solutions.

Mis Meyer's paid $3600 all together for the equipment, furniture and decorations for her restaurant. The equipment cost $500 mor
Tju [1.3M]

Answer:

The equipment will cost $1740.

Step-by-step explanation:

Let the Cost of equipment, furniture and decoration be x, y and z.

Now, According to question,

x + y + z = 3600 ...... (1)  (cost of all items)

x = 500 + y (∵ equipment cost 500 more than furniture)

and y = 2z ( ∵ furniture twice as much as decoration)

so, z = y/2

Now substituting the value of x and z in eq (1)

x + y + z = 3600

500 + y + y + \frac{y}{2} = 3600

2y + \frac{y}{2} = 3600 - 500

\frac{5y}{2} = 3100

y = \frac{3100\times 2}{5} = 1240

So, the cost of furniture (y) = 1240

∴ Cost of equipment = y + 500 = 1240 + 500 = 1740

Therefore the cost of equipment was $1740.
