What this question is asking, without all the wording, is what is 75% of 1400. You can easily find this by multiplying 1400 by 0.75. This will be your sales tax.
Sales Tax: $1050
Answer:
2880
Step-by-step explanation:
The "." or · means multiplication.
"!" means multiplying every consecutive positive whole number starting from 1 until the number infront of the "!". It's called a <u>factorial</u>.
4! = 1·2·3·4 = 24 The factorial of 4
5! = 1·2·3·4·5 = 120 The factorial of 5
Substitute the values of the factorials, then multiply them to solve.
5! · 4!
= (1·2·3·4·5) · (1·2·3·4)
= 120 · 24
= 2880 Answer
Therefore 5!·4! = 2880.
Answer: less than
So you have:
-8n - 13 ≤ 27Now, solve for n:
-8n -13+13 ≤ 27 + 13-8n ≤ 40
Now, to divide both sides by a negative number (-8), you must change the inequality to ≥
-8n/-8 ≥ 40/-8n ≥ -5
Answer:
20
Step-by-step explanation:
The cost of the x mangoes was ...
c = 10(x/4)
The revenue from the sale of mangoes was ...
r = 20(x-5)/5
The profit is the difference between revenue and cost:
10 = r - c = 20(x -5)/5 -10(x/4) = 1.5x -20 . . . . substitute and simplify
30 = 1.5x . . . . . add 20
20 = x . . . . . . . .divide by 1.5
The trader bought 20 mangoes.
_____
<em>Check</em>
He paid 20(10/4) = 50 naira. He sold the 15 good mangoes for 20/5(15) = 60 naira, so made a 10 naira profit.
The first statement is correct
To calculate the distance we have to substrate the values of the Y axis only since X values are constant so the distance IS 4 - - 7=4+7=11
