To answer the question above, first, just multiply directly the numbers. 
                                 3.278 x 4.23 = 13.86594

The rule for the significant figures for multiplication of two or more numbers is that the number of significant figures of the product should be equal to the least number of significant figures of the factors. From the given above, the first factor has 4 significant figures and the second only has 3. Therefore, the product should only have 3 significant figures. The answer is letter B. 13.9

Let us first multiply the numbers that are given in the question.
3.278 x 4.23 = 13.86594.
Now comes the important part of finding the correct answer. The first number has four significant figures and the second number has three significant figures. The result or the product of these two numbers should have three significant figures. The answer will then be 13.9. The correct option among all the options that are given in the question is option "B".

If 97 of 200 is 100% then how much of 200 is 112%
pickupchik [31]
To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 112 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 112 is 100%, so we can write it down as 112=100%.
4. We know, that x is 200% of the output value, so we can write it down as x=200%.
5. Now we have two simple equations:
1) 112=100%
2) x=200%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
112/x=100%/200%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 200% of 112

112/x=100/200
(112/x)*x=(100/200)*x - we multiply both sides of the equation by x
112=0.5*x - we divide both sides of the equation by (0.5) to get x
112/0.5=x
224=x
x=224

now we have:
200% of 112=224

Joyce saved $80 on an item that was 65<br> %<br> off. What was the original price?
Xelga [282]
The answer is 132. 132 is the original price. 80$ x 65% = 52. 80 + 52 = 132. So 132 is answer and original price.
