Answer:
B
Step-by-step explanation:
Since the triangle is right use the tangent ratio to find x
tan64° = =
Multiply both sides by 11
x = 11 × tan64° = 22.55 → B
Answer:
0.002M
Step-by-step explanation:
2.7= -log(H^+)
-2.7=log(H^+)
10^-2.7 M=H^+
0.0002M=H^+
Answer:
The answer is 6
Step-by-step explanation:
ABC is 72, 66, 42 and DEF is 12, 11, 7
simply divide the largest shape measurements by the smaller one.
72÷12
66÷11
42÷7
you get 6 in all of them, this technique may not work all the time.
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.
