Answer:

check your math

Step-by-step explanation:

The first subtraction was correct:

36 -7 3/4 = 28 1/4

The second subtraction needs to be revisited.

28 1/4 -6 2/4 = 27 5/4 -6 2/4 = 21 3/4

You can do what you did, but you need to pay attention to the signs.

28 1/4 -6 2/4 = (28 -6) +(1/4 -2/4) = 22 - 1/4 = 21 3/4

The result of subtracting 2/4 from 1/4 is -1/4, not +1/4.

_____

The length of the first cut piece was 21 3/4 inches.

levacccp [35]

Answer:

2, 3

1.01, 1

Percentage uncertainty

Step-by-step explanation:

a) The significant figures in the number 99 is 2

The significant figures in the number 100 is 3

b) Uncertainty in each of the numbers for both the numbers is 1

Percentage uncertainty

$\text{Percentage uncertainty}=\frac{\text{Uncertainty}}{Value}\times 100 \\\Rightarrow \text{Percentage uncertainty}=\frac{1}{99}\times 100=1.01$

Percentage uncertainty = 1.01

100

$\text{Percentage uncertainty}=\frac{\text{Uncertainty}}{Value}\times 100 \\\Rightarrow \text{Percentage uncertainty}=\frac{1}{100}\times 100=1$

Percentage uncertainty = 1

c) Percentage uncertainty is a better way to express the numbers as the significant figures do not show the actual value of the numbers.
