What number is 100,00 more than seven hundred two thousand, eighty-three

$75 before tax. Disc: 10% Tax: 7%, Tip: 20% what’s the total?

ololo11 [35]

Answer:

$102.75

Step-by-step explanation:

Given the following question:

We are given a cost of 75 dollars and are being asked to find the total cost after adding a tip, tax, and disc to the cost. To find this answer we will use the formula to calculate percentages making sure we use 75 as our base for each addition to our total cost.

Formula to calculate percentages:

$\frac{p\times n}{100}$

First the disc:

$\frac{10\times 75}{100}$
$10\times75=750$
$750\div100=7.5$
$=7.5$

Next the tax:

$\frac{7\times75}{100}$
$7\times75=525$
$525\div100=5.25$
$=5.25$

Last but not least the tip:

$\frac{20\times75}{100}$
$20\times75=1500$
$1500\div100=15$
$=15$

Finally add:

$75+7.50+5.25+15=102.75$
$=102.75$

The total cost after adding the disc, tax, and the tip will be "$102.75."

Hope this helps.

A shop has 8 different types of postcards and at least 13 of each type. how many selections of 12 postcards are there if

Zolol [24]

Answer:

Answered

Step-by-step explanation:

It is a combbinatorics problem. let's think as we need to do 8 partitions

of these 13 to separate the postcards of different types. So The number of

partitions of n=13 into r=8 terms counting 0's as terms as C(n+r-1,r-1).

(a)

Here n=13 and r=8, put it in the above formula so we get C(13+8-1,8-1)= C(20,7)= 77520 selections.

b).

Here, either (i) we can choose none of type I or (ii) we choose one of type I

Case(i): r=7, n=12 (Here we have only 7 types to choose from)

Case(ii): r=7, n=11 (Here we have only 11 cards to choose and only 7 types to choose them from)

Case (i) + Case(ii) = ,C(12+7-1,7-1) + C(11+7-1,7-1) = C(18,6) + (17,6) = 18564+12376 = 30940 selections.

Someone can help me with 31 & 33? i need help

nika2105 [10]

31. It gives you the equation f(x) = -2x + 4 and asks you to solve for f(12). To solve this you must replace x in the equation -2x + 4 with 12 like so:

-2(12) + 4

Remember that when solving this use your rules of PEMDAS. In this case you will first multiply -2 and 12 then add the product with 4

-24 + 4

f(12) = -20

33. Replace x in the equation x³ - x with 5 like so...

5³ - 5

Again, remember to use the rules of PEMDAS to solve this. First take the cube of 5 then subtract 5 from the answer

125 - 5

g(5) = 120

Hope this helped!
