What is the steps for Discount

Mathematics
1 answer:
Inga [223]3 years ago
3 0

1.) Divide the percentage discount by 100 to convert it into decimal. For example, if a shop offers a 40 per cent discount, divide 40 by 100 to get 0,4.

2.) Multiply the decimal number by the original price to find the discount percentage. For example,if the original price is $120, 120 is multiplied by 0,4 to find the discount which is $48.

3.) <span>Subtract the discounted amount to the original price to find the actual price with the discount subtracted. For example, subtract $48 to $120 to find that the price with the discount is $72.</span>

A restaurant menu has five kinds of soups, seven kinds of main courses, six kinds of desserts, and five kinds of drinks. If a cu
ryzh [129]

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

Does this relation represent a function why or why not?
Serga [27]

Answer:

This is a function and it's because there's only one input for every output.

Step-by-step explanation:

Note: Although 5 and 1 both point to the same number this doesn't take away the validity of the function. :)

PLEASE HELP 20+ POINTS!! What is the cosine equation of the function shown?
noname [10]

Answer:   \bold{y=7\ \cos\bigg(x-\dfrac{\pi}{4}\bigg)-4}

<u>Step-by-step explanation:</u>

y = A cos (Bx - C) + D

  • A (amplitude) = max - D
  • B = Period/2π  --->   Period is the distance from max to next max
  • C = B · Phase Shift  ---> Phase shift is distance from y-axis to max
  • D (vertical shift) = (max + min)/2

D = (max + min)/2     =     (3 - 11)/3      =  -4

A = max - D               =     3 - (-4)         = 7

Period = 9π/4 - π/4   =    8π/4            = 2π

B = Period/2π           =    2π/2π          = 1

Phase Shift = π/4 - 0 =     π/4

C = B · Phase Shift    =  1 · π/4            = π/4

Equation:

           y = 7 cos (1·x - π/4) + (-4)
