When Vlad moved to his new home a few years ago, there was a young oak tree in his backyard. He measured it once a year and foun
Nonamiya [84]

> How tall was the tree when Vlad moved into the house?

We know that the tree grew by 26 cm per year, the current height is 292 cm and 4.5 years have already passed, therefore the original height was:

original height = 292 cm – (26 cm / year * 4.5 years)

original height = 175 cm

 

> How many years passed from the time Vlad moved in until the tree was 357 centimeters tall?

Calculate for time using the formula:

time = (current height – original height) / 26

time = (357 cm – 175 cm) / (26 cm/ year)

<span>time = 7 years</span>

Explain why 2-81273-05213-8 is an invalid UPC number.
sammy [17]

Answer:

Part 1) Is not a valid code

Part 2) The last digit should be 6 in order to make it a valid code

Step-by-step explanation:

we have

2-81273-05213-8

we know that

The last number is the check digit (8)

<em>Verify the UPC number</em>

step 1

Sum the digits in the odd positions, starting at the left

so

2+1+7+0+2+3=15

step 2

Multiply the answer in step 1 by 3

15(3)=45

step 3

Sum the numbers in the even positions, ignoring the last (12th) digit because that is the check digit that you are verifying

Do not multiply this number by 3.

8+2+3+5+1=19

step 4

Add the results from steps 2 and 3

45+19=64

step 5

Subtract the number in step 4 from the next higher multiple of 10. In this example, the next multiple of 10 after 64 is 70, so subtract 64 from 70:

70-64=6

This number is not equal to the check digit (8)

therefore

Is not a valid code

The last digit should be 6 in order to make it a valid code
