Two friends go out to eat and order the same meal. They pay a 6% sales tax and a 20% tip on their meals. The total bill, includi
vova2212 [387]

Sales tax and tip will increase the price of an item.

The cost of each meal is: $10.89

Let the cost of both meals be x.

A 20% tip means that, the current price is:

Price = x \times (1 + 20\%)

A 6% sales tax on the meal means that, the current price is:

Price = x \times (1 + 20\%) \times (1 + 6\%)

So, we have:

Price = x \times (1 + 0.20) \times (1 + 0.06)

Price = x \times (1.20) \times (1.06)

Price = x \times 1.272

The amount paid is $27.72

So, the equation becomes

27.72= x \times 1.272

Make x the subject

x = \frac{27.72}{1.272}

x = 21.78

So, the cost of each meal is:

Each= \frac{21.78}{2}

Each= 10.89

Hence, the cost of each meal is: $10.89

How many ways can six friends be arranged around a circular dinner table?
Mice21 [21]
A question such as this one is a little tricky since the people seated are not in a straight line. 

For a circular table seating question, (n-1)! formula is used. Without restrictions 5! people can be seated. 

You might be wondering why it is not 6!, this is because the first person will the the 6 person so you are accounting for the same person twice. 

Hope I helped :)

Triangle ABC is similar to triangle LMN by the similarity postulate
likoan [24]

Answer:

Same as Angle B. 90 degrees.

Step-by-step explanation:

If triangles are similar then they have the exact same angle measures. Angle m will have the same value as angle B. If angle B's measure is not found, then find it by adding angle A and angle C together and subtract from 180.

The picture is cut off but if A =60 and C=30 then 60+30=90 and 180-90=90. Angle B and M are both 90 degrees.
