To what decimal place should each answer be rounded? How many significant figures does the rounded answer have? A. 9 cm+2.8 cm=1
FromTheMoon [43]

Answer:

a) rounded to the ones place and 2 significant figures.

b) rounded to tenths place and 1 significant figure.

Step-by-step explanation:

Significant figures are the number of needed place values for accuracy. Round each number according to the least number of significant figures within the problem.

A. 9 cm+2.8 cm = 11.8 cm rounds to 12 which has 2 significant figures. Round to the ones place value since 9 has the least number of significant figures.

B. 0.135 atm+0.6 atm = 0.735 atm rounds to 0.7 atm which has 1 significant figure. Zero preceding the value is not considered significant. Round to the tenths place value since 0.6 has the least number of significant figures.

Answer:

10x -  \frac{1}{x}  = 3 \\ 10x = 3 +  \frac{1}{x}  \\ 10x =  \frac{3x + 1}{x}  \\ 10x \times x = 3x + 1 \\ 10 {x}^{2}  = 3x + 1 \\ 10 {x}^{2}  - 3x - 1 = 0 \\ 10 {x}^{2}  - 5x + 2x - 1 = 0 \\ 5x(2x - 1) + 1(2x - 1) = 0 \\ (5x + 1)(2x - 1) = 0 \\  \\ 5x + 1 = 0 \\ 5x =  - 1 \\ x =  \frac{ - 1}{5}  \\  \\ 2x - 1 = 0 \\ 2x = 1 \\ x =  \frac{1}{2}
