In a plane, if two lines are each parallel to a third line, then they are _________ to each other.
iogann1982 [59]
Parallel. This is pretty simple if you either a) Picture it in your head, or b) look at each option logically. lets try out b)

The last option does not really apply to lines, and is for angles. (unless your talking about the adjecent sides of an angle, but this would mean they meet at a vertex) Perpendicular, doesnt make sense because if they were perpindicular on a plane, (2-d) then it would be immpossible for BOTH to be parallel to a third line. This leaves the first option, which makes sense.

(05.03)Calculate the area of the regular pentagon below: A regular pentagon with side length of 22.3 inches and dotted line from
Marat540 [252]

Answer:

The area of the regular pentagon is A=858.55\ in^{2}

Step-by-step explanation:

we know that

The area of a regular polygon is equal to

A=\frac{1}{2}Pa

where

P is the perimeter of the regular polygon

a is the apothem

Find the perimeter P

P=5(22.3)=111.5\ in ----> the regular pentagon has five equal sides

a=15.4\ in ---> distance from center to middle of side

substitute

A=\frac{1}{2}(111.5)(15.4)

A=858.55\ in^{2}

-15x=-4x... How to move the x to the left?
Delvig [45]
-15x=-4x

We know that adding zero wouldn’t change the value

-15x=-4x+0

Now we can add 4x (since that’s the opposite of the negative sign) to the other side

-11x=0

0 divided by 11 is 0

x=0

The production cost, represented by y, of a Bluetooth device, is equal to the product of labour cost (m) and number of devices (
pogonyaev

It should be noted that the equation to represent the production cost will be y = mx + q.

<h3>How to calculate the equation</h3>

From the information given, the production cost, represented by y, of a Bluetooth device, is equal to the product of labour cost (m) and number of devices (x) in addition to a constant equipment renting fee (q). This will be: y = mx + q.

Changing the subject of the formula to m will be:

y = mx + q

y - q = mx

m = (y - q)/x
