ABC Office Supply offers an electric typewriter for $129.95. If ABC received a 15% markup on cost by selling the typewriter at t

const2013 [10]

A 15% percent markup means that the typewriter cost was increased by 15%, or 0.15 by moving the decimal 2 places to the left. If the original price was x, and 15% of it is 0.15*x, we can add them up to get 1.15*x=129.95. Dividing both sides by 1.15, we get x=113 dollars

I need help with these please... anyone?

The total measure of the interior angles of each figure will be:

180 (n-2) = 180 (4 - 2) = 360

Now add all those angles and set them equal to 360.

41 + 133 + 86 + x = 360

x is the unknown angle.

260 + x = 360
x = 100

The missing angle that is Not labeled in any of the figure is 100°

Hope this helps :)

The sum of two consecutive integers is -239 find the two integers

xenn [34]

Answer:

The two consecutive integers are -119 and -120

Step-by-step explanation:

As we know that these two integers are consecutive, that means that they will have a difference of 1. This means that we can find the two integers by adding 1 to the sum of -239 and then dividing it by two

$1-239=-238\\\frac{-238}{2} =-119\\-119-1=-120$

Answer: 1050

Step-by-step explanation:

Number of combinations of selecting r things out of n = $^nC_r=\dfrac{n!}{r!(n-r)!}$

such that $^nC_1=n$

Given: A restaurant menu has 5 kinds of soups, 7kinds of main courses, 6 kinds of desserts, and 5 kinds of drinks.

If a customer randomly selects one item from each of these four categories, then by fundamental counting principle , the number of different outcomes are possible = $^5C_1\times \ ^7C_1\times\ ^6C_1\times\ ^5C_1 =5\times7\times6\times5=1050$

hence, total number of outcomes = 1050
