Answer:

12 units

Step-by-step explanation:

A-------6--------B-------?--------C

Midpoint is center that divides the line segment into two equal halves.

∴    AB = BC

If line AB measures 6 units in length, then, line BC will measure 6 units in length.

     AB = BC = 6 units

     AC = AB + BC

     AC = 6 units + 6 units

     AC = 12 units

OR

We can say If B is the midpoint of AC, then AC is twice as long as AB.

     AC = 2AB

     AC = 2 × 6 units

     AC = 12 units        

Therefore, the length of line AC is 12 units.

No, because 15 x 22.3 = 334.5 so he can't travel 500 miles with one tank of gas.

An electrician needs to cut a 49 m piece of wire into two pieces so that one piece is 5 m longer than the other piece. What is t
gulaghasi [49]

The length of the shorter wire that the electrician cuts so that the difference between those two is of 5 m is 22.5.

Given to us

An electrician needs to cut a 49 m piece of wire into two pieces so that one piece is 5 m longer than the other piece.

<h3>What are the two equal parts of the wire?</h3>

We know that the length of the wire is 49 m, therefore, to cut the wire in two equal parts divide the total length of the wire by two,

\dfrac{49}{2} = 24.5

Thus, the length of each side will be 24.5.

<h3>What is the length of the shorter piece of wire?</h3>

Since we need to cut the wire such that one side of the wire is 5 less than the other, we already know the length of the equal sides deduct (5/2) from both sides to create a difference between the length of the wire.

Length of the shorter wire = 24.5 -2.5 = 22.5

Length of the longer wire = 22.5 + 5 = 27.5

Hence, the length of the shorter wire that the electrician cuts so that the difference between those two is of 5 m is 22.5.

I need some help with this worksheet! Major points !!! . (not good with percentages)
yuradex [85]

To make the equations you must first get the percents and make them into a decimal. then multiply the money by the decimal

EX: $230.76 with a profit of 30%

First make the percent a decimal to do so move the . over to the left two times resulting in the number .30

so the equation is 230.76(.30)

which equals 69.228

now simplify it making the answer $69.23

now to get the store price, add manufacture price with the %30 of the the MP resulting in the answer

$299.99
