Answer:
This is the answer of your question.
Answer:
It would be about 1.3 a piece.
Step-by-step explanation:
If there is 8 slices and six friends i think u would divide 8 by 6 which is 1.3 repeating which rounds up to 1.3
(Brainliest plz?)
50%=1/2
2 is commonly used to convey half
15*2=30
There are 30 total student in the class
To do this you need to "complete the square" as follows:
<span>y = 2x^2 - 12x + 16 </span>
<span>y = 2(x^2 - 6x + 8) </span>
<span>y = 2(x^2 - 6x +8 +1 -1) (you "complete the square" by bringing the last term (8) up to "half of the middle co-efficient squared". Middle co-efficient is -6, half is -3, squared is 9. To get from 8 to 9 you must add 1 (+1), but if you add 1 you must subtract 1 (-1) so that you don't change the overall value of inside the bracket) </span>
<span>y = 2(x^2 - 6x +9) - 2 (bring the -1 outside of the brackets) </span>
<span>y = 2(x-3)^2 - 2 </span>
<span>and that is your final answer. I hope this helps!</span>
Answer:
The UPC is not valid..
Step-by-step explanation:
The Universal Price Code is represented in the form of bars which is scanned when we purchase something.
The last digit of the UPC is the check digit.
Give UPC = 375407370090
To check whether the UPC is valid or not.
Step 1:
Add the digits at odd positions.
3 + 5 + 0 +3 + 0 + 9 = 20
Step 2:
Multiply the number obtained in step 1 by 3
20*3 = 60
Step 3:
The digits at even positions have to be added. The last digit has to be ignored as it is a check digit.
7 + 4 + 7 +7 +0 = 25
Step 4:
Add the numbers obtained in Step 2 and step 3
60 + 25 = 85
Step 5:
The number obtained in step 5 is subtracted from the next multiple of 10.
In the above case,
85 will be subtracted from 90.
90 - 85 = 5
For a valid UPC, the answer to step 5 is equal to the last digit of UPC.
In the above case, the answer is 5 which is not equal to zero.
So, the UPC is not Valid.
