A) how many significant figures are in the numbers 99 and 100? (b) if the uncertainty in each number is 1, what is the percent uncertainty in each? (c) which is a more meaningful way to express the accuracy of these two numbers, significant figures or percent uncertainties?

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

99

Percentage uncertainty = 1.01

100

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.

the answer is stop cheating on things stoopid

step-by-step explanation:

im eatin up the 44

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
