Brianna typically sells candy bars for $4.70. During a sale she prices them at $3.30. What is the approximate percent discount o

Elena-2011 [213]

Answer:

30%

Step-by-step explanation:

One simple way of finding out discounts is to simplify our answer by starting with 10% and subtracting from that.

If the original price were to have a 10% discount, it would be 4.70/10 for .47 per 10% off.

10% gives us 4.23, so let's take another 10% off by doing 4.23-.47, which is equal to 3.76. While lower, it's not our answer so lets do another 10%

3.76-4.7 = $3.29

With a total of 3 10%'s taken off, or in this case, 30% off, we can conclude that the discounted prices of $3.29 is 30% of the original price.

Which of the following is defined by a line parallel to one side of a triangle

Katarina [22]

Answer:

Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.

Step-by-step explanation:

Triangular Proportionality Theorem states that:

If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.

Let us consider the triangle ΔABC as shown in attached figure.

$DE$ ║ $AC$

then

$\frac{BD}{DA} = \frac{BE}{EC}$

Therefore, Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.
