Consider the two triangles.

brilliants [131]

The ratios StartFraction U V Over Z Y EndFraction , StartFraction W U Over Z X EndFraction , and StartFraction W V Over X Y EndFraction are equivalent.

<h3>Similarity theorem of triangles</h3>

For two triangles to be similar, the ratio of the measure of similar sides of the triangle must be equal to a constant known as a scale factor.

From the given figures, the expression that can be used to prove that the triangles are similar is as shown;

UV/ZY = WU/ZX = WV/XY

Hence the correct option is to show that the ratios StartFraction U V Over Z Y EndFraction , StartFraction W U Over Z X EndFraction , and StartFraction W V Over X Y EndFraction are equivalent.

A jeweler is dividing

Anuta_ua [19.1K]

Answer: OPTION D: $\frac{3}{32}$

Step-by-step explanation:

By definiton, fractions have the following form:

$\frac{a}{b}$

Where "a" is called numerator and "b" is the denominator. The numerator and the denominator are Integers.

In order to solve this exercise you need to remember de Division of fractions:

$\frac{a}{b}\div\frac{d}{e}=\frac{a}{b}*\frac{e}{d}=\frac{a*e}{b*d}$

In this case, according to the information given in the exercise, you know that $\frac{3}{8}\ lb$ of rubies are divided into 4 lots.

Therefore, in order to calculate the weight in pounds of each lot, you need to divide $\frac{3}{8}\ lb$ by 4.

Then, you get the following result:

$\frac{3}{8}\ lb\div4=(\frac{3}{8}\ lb) (\frac{1}{4})=\frac{3}{8*4}\ lb=\frac{3}{32} \ lb$

As you can notice, this result matches with the Option D.

Is 2(5m-4)-3(m-5)^2 equivalent to -3m^2+40m-83? Show your work.

ivann1987 [24]

$\\ \sf\longmapsto 2(5m-4)-3(m-5)^2$

$\\ \sf\longmapsto 10m-8-3(m^2-10m+5^2)$

$\\ \sf\longmapsto 10m-8-3(m^2-10m+25)$

$\\ \sf\longmapsto 10m-8-3m^2+30m-75$

$\\ \sf\longmapsto -3m^2+30m+10m-75-8$

$\\ \sf\longmapsto -3m^2+40m-83$
