Answer:
$10.8 is left.
Step-by-step explanation:
Given that,
Total amount = $54
Left amount = 20%
We need to find how much tip should you leave. It means we need to find 20% of 54. So,

So, $10.8 is left.
Answer:
y-6 = -7x + 21
Step-by-step explanation:
Find the slope
(-8 - 6)/(5-3)
-14/2 = -7
Now find the formula
y-6=-7(x - 3)
y-6 = -7x + 21
Another way to write it is
y= -7x + 27
Answer:80
Assume the number to be 400 for instance,
10% of 400 increased = 400 + ( 10/100 × 400 )
= 400 + 40 = 440
The resulting number decreased by its 10% = 400 - (10/100 × 400)
= 400 - 40 = 360
Now, net decrease = 440 - 360 = 80
Summary of information:
total output = 3600 units per year
split into 18 equal orders
cost per order = $40
cost to store a unit for one year = $20
lead time (i.e. storage before shipping) = 5 days
Solution:
quantity split into 18 orders, so 3600/18= 200 units per order.
Order cost = $40 * 18 orders = $720 ..........................(A)
Storage cost:
Each order has 200 units, stored for 5 days = 200*5=1000 unit-days
storage needed for 18 orders = 1000*18 = 18000 unit-days = 50 unit-years
Total storage cost = 50 unit-years * $20 / unit year = $1000...........(B)
Total ordering cost = (A) + (B) = $720+$1000 = $1720
0.999999999... indeed can be 1.
Same as 0.33333... is equal to 1/3. Though you can see it's a fraction.
Same thing is basically with 0.99999... to 1. It's just the fact that the 1 is a whole number but the 0.9999... looks messy.
The terms of the associated sequence 0.9, 0.99, 0.999,..., do "get arbitrarily close" to 1, in the sense that, for each term in the progression, the difference between the term and 1 gets smaller and smaller.
The number 0.999... (with the ellipse) means that it goes on forever, there is no stop to it meaning that it basically is, and has been proven, that it is 1.
Hope this helps :)
