determine whether each of the strings of 12 digits is a valid upc code. a) 036000291452 b) 012345678903 c) 782421843014 d) 726412175425

Answers

Answer 1

a) 036000291452: Yes, this is a valid UPC code. b) 012345678903: Yes, this is a valid UPC code. c) 782421843014: No, this is not a valid UPC code. d) 726412175425: No, this is not a valid UPC code.

a) The string 036000291452 is a valid UPC code.

The Universal Product Code (UPC) is a barcode used to identify a product. It consists of 12 digits, with the first 6 identifying the manufacturer and the last 6 identifying the product. To check if a UPC code is valid, the last digit is calculated as the check digit. This is done by adding the digits in odd positions and multiplying the sum by 3, then adding the digits in even positions. The resulting sum should end in 0. In the case of 036000291452, the check digit is 2, which satisfies this condition, so it is a valid UPC code.

b) The string 012345678903 is a valid UPC code.

To check the validity of the UPC code, we calculate the check digit by adding the digits in odd positions and multiplying the sum by 3, then adding the digits in even positions. The resulting sum should end in 0. In the case of 012345678903, the check digit is 3, which satisfies this condition, so it is a valid UPC code.

c) The string 782421843014 is not a valid UPC code.

To check the validity of the UPC code, we calculate the check digit by adding the digits in odd positions and multiplying the sum by 3, then adding the digits in even positions. The resulting sum should end in 0. In the case of 782421843014, the check digit is 4, which does not satisfy this condition, so it is not a valid UPC code.

d) The string 726412175425 is not a valid UPC code.

To check the validity of the UPC code, we calculate the check digit by adding the digits in odd positions and multiplying the sum by 3, then adding the digits in even positions. The resulting sum should end in 0. In the case of 726412175425, the check digit is 5, which does not satisfy this condition, so it is not a valid UPC code.

There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter.
To the nearest meter, how many meters are in 275 inches? Enter the answer in the box.
meters
0

Answers

Answer:

7 m

Step-by-step explanation:

We are told that;

100 cm = 1 m

Thus; 2.54 cm = 2.54 × 1/100 = 0.0254 m

This means that;

1 inch = 0.0254 m

Thus; 275 inches will give; 275 × 0.0254/1 = 6.985 m

Approximating to the nearest metre gives 7 m

w is directly proportional to u if w=5 when u=3,find u when w is =2/7​

Answers

Answer:

u = 6/35

Step-by-step explanation:

w = k * u

w = ku

Where

k = constant of proportionality

if w=5 when u= 3

w = ku

5 = k * 3

5 = 3k

k = 5/3

find u when w is =2/7​

w = ku

2/7 = 5/3 * U

2/7 = 5/3u

u = 2/7 ÷ 5/3

= 2/7 × 3/5

= (2*3)/(7*5)

= 6/35

u = 6/35

A teacher purchased 20 calculators and 10 measuring tapes for her class and paid $495. Later, she realized that she didn't order enough supplies. She placed another order of 8 of the same calculators and 1 more of the same measure tape and paid $178.50.The system represents the situation

`20c+10m=495`

`8c+1m=178.50`

Find the cost of one calculator and the cost of one measure tape using one of our methods of solving systems.

Answers

Answer:

Equations are

20c + 10m = 495..............(1)

8c + 1m = 178.5.................(2)

Now ,  equation (2) * 10 = 80c + 10m = 1785...........(3)

So, Eq. (3) -  Eq(1) =

80c + 10m - 20c - 10m = 1785 - 495

60c = 1290

c= 21.5

********************************************************

Now place the value of c in Eq (2)

So , m =6.5

Find the area of a vertical cross section through the centers of the bases of a cylinder with height of 27 inches and a circumference of about 47.1 inches. Use 3.14 for π.

Answers

Answer:

405 in^2

Step-by-step explanation:

Given data

Height= 27in

Circumference= 47.1 in

let us find the radius and the diameter of the base of the cylinder

from

C=2πr

47.1= 2*3.142*r

47.1= 6.284r

r= 47.1/6.284

r= 7.5 in

Diameter= 2r

D= 7.5*2

D= 15in

Hence the area of the cross-section

=H*D

=27*15

=405 in^2
