Brand W: 500 napkins for $2.87

1 answer:

3 0

The best way, in my opinion, to do this, is to find the unit rate of each napkin brand, or the cost per napkin. To do this, divide the money amount by the amount of napkin they give you.

/Brand W:2.87/500=.00574 \
\Brand X: 1.27/200=.00635 \ These are the
/Brand Y: .62/100 =.0062 / cost per napkin.
 \Brand Z: 1.37/250=.00548 /

Which one out of these 4 values is the lowest value? Obviously the two with the 6 in the thousandths place are more expensive than the ones with the 5s in the thousandths place, so that already eliminates Brand Z and Brand W.

What do we have left?

Brand X: 1.27/200=.00635
Brand Y: .62/100 =.0062
 Cool. Which of these is a smaller number? Tip: If the first number besides 0 is the same, check the next one! You should get that Brand Y is the cheapest! :) Hoped this helped!

Essentially, all interior angles = 60°

By definition of a triangle, a triangle has 3 sides. It is given that the total measurement of the sides is 12. Divide 12 with 3: 12/3 = 4

Solve for x. The triangles in each pair are similar.

KatRina [158]

Answer:

Step-by-step explanation:

You need to pay very close attention to the triangle similarity statement. This says that triangle NML is similar to triangle NVU. But if you look at the way that triangle NVU is oriented in its appearance, it's laying on its side. We need to set it upright so that angle N is the vertex angle, angle V is the base angle on the left, and angle U is the base angle on the right. When we do that we see that sides NV and NM are corresponding and exist in a ratio to one another; likewise with sides VU and ML. Setting up the proportion:

$\frac{NV}{NM}=\frac{VU}{ML}$
