How should the computed result be reported, to the proper number of significant figures, for the following set of 0.0053 ? 2.7800 mathematical operations? (112.2 - 5.2) × A. 0.2040 B. 0.20 C. 0.204 D. 0.20399 O E. 0.2

A rectangular block of wood is measured to have the dimensions 11.2 cm, 3.4 cm and 4.10 cm. Compute the volume of the block using the rules of significant figures. O 1.645 x 10² cm² a) b) 16 x 10² m² c) 1.6 x 10² cm² d) 1.60x 10² cm² Question 8 (Mandatory) (10 points) Saved 0:21

A rectangle has a length of (5.1 ± 0.2) m and a width of (2.3 ± 0.1) m. Calculate: (a) the area and (b) the perimeter of the rectangle, Give the uncertainty in each value.

1. Multiplication or division: keep the same number of significant figures in the product or quotient as is in the least precise factor. Examples: 3.1 * 25.6=79.360000... = 79 6.7/981.0=0.0068297655... = 0.0068 keep only 2 significant digits 2. Powers or roots: keep the same number of significant figures as in the original number. Example: Sqrt(38) 6.164414... keep only 2 significant digits = 6.2 (11.6)² = 134.5600000... = 135 Exercises 3. Addition or subtraction: Round off, to the number of decimal places determined by the number with the least number of places beyond the decimal point. Example: 31.5+24.61 +3.28+1.19 +0.762 +0.003 = 61.345 1. 3.9 * 78.9= = 61.3 (correct result) 2. 32.01 +96.321 +36.98 +0.00023 +28.9= 3. 26.9/98 = 4. 421 0.003 =

How many significant figures are there in (a) 0.0210, (b) 5.060, (c) 7.10 * 10-4,(d) 1.0 * 105?

Which one of the choices below represents the preferred practice regarding significant figures when multiplying the following: (12.00)(0.811)(0.004)?   A. 0.038928   B. 0.038   C. 0.04   D. 0.039   E. 0.0389

The extraterrestrials in an exoplanet in a distant galaxy have the following units to measure distances.1 dray = 12 elim; 1 toof = 24 dray; 1 chin = 1250 toof. a. Convert 2.4 chin to elim. __________________ elim b. The alien grows vegetables in 16.0 square dray (i.e., dray2) patch. Calculate the area of the patch insquare elim (i.e., elim2).____________ clim2

1)A grocery store sells 5-lb bag of apples. A customer bought apples weekly and made a record of his purchases: The weighing scale in the grocery store has an uncertainty of 10.3 lb. The customer obtained the following measurements: Week 1: weight is 4.8 Ib Week 2: weight is 5.3 lb Week 3: weig is 4.9 Ib Week 4: weight is 5.4 lb What is the Percent Uncertainty of the bag's weight?

It's showing that b is not correct. Thank you for your help with this practice problem.

calculate the following and express the answer in the proper number of significant figures: (3.245x0.035x9.0023)/(4.076x2.01x42.3)
