When subtracting, the result should be rounded to the least number of decimal places. 5.00 has two decimal places and 2.1 has one, so the result should be rounded to one decimal place: 5.00 - 2.1 = 2.90 becomes 2.9.

Using the property of exponents, we combine the exponents: 5^(2 + (-3)) = 5^(-1).

6.022 rounded to 3 significant figures is 6.02.

6.022 rounded to three significant figures is 6.02 × 10^23.

60 ÷ 3 = 20; 4 × 5 = 20; 20 + 20 = 40.

First, calculate 12 ÷ 3 = 4. Now, 7 × 4 - 4 = 28 - 4 = 24.

The result should be rounded to one decimal place, giving 12.4.

When adding, the result should be rounded to the least number of decimal places. 12.11 has two decimal places and 0.3 has one, so the result should be rounded to one decimal place: 12.41 becomes 12.4.

Adding 1011 and 1101 in binary results in 11110.

When adding the polynomials, combine like terms: (2x^2 + 3x + 4) + (3x^2 - x + 2) = 5x^2 + 2x + 6.

When adding the polynomials, combine like terms: (2x^2 + x^2) + (3x - 5x) + (-4 + 6) = 3x^2 - 2x + 2.

Adding the two polynomials gives (3x^2 + 4x^2) + (2x - x) + (1 + 5) = 7x^2 + x + 6.

Adding the two polynomials gives (3x^2 + 4x^2) + (2x - 3x) + (-1 + 5) = 7x^2 - x + 4.

Adding the coefficients of like terms gives 6x^2 + 2x + 5.

Adding the two polynomials gives (2x^2 + 5x^2) + (3x - x) + (4 + 2) = 7x^2 + 2x + 6.

Adding the polynomials gives (3x^2 + x^2) + (2x - x) + (1 + 4) = 4x^2 + x + 5.

Cytokinesis results in the physical separation of the cytoplasm, leading to the formation of two daughter cells.

Destructive interference occurs when two waves of equal amplitude meet out of phase, resulting in an amplitude of zero.

In division, the result should have the same number of significant figures as the measurement with the least significant figures. 100.0 has 4 significant figures and 4.00 has 3 significant figures, so the answer should be 25.0 with 3 significant figures.

150.0 has four significant figures and 3.00 has three significant figures. The result should be reported with three significant figures: 50.0.

In division, the result should have the same number of significant figures as the measurement with the least significant figures. 6.38 has 3 significant figures and 2.0 has 2 significant figures, so the answer should be rounded to 2 significant figures: 3.19 becomes 3.2.

In division, the result should have the same number of significant figures as the measurement with the least significant figures. 8.0 has 2 significant figures and 2.00 has 3 significant figures, so the answer should be 4.0 (2 significant figures).

Cutting a circle from the folded edge results in two identical circles when unfolded.

Folding a rectangular paper in half lengthwise results in a smaller rectangle.

Folding lengthwise creates a smaller rectangle.

When two waves of equal amplitude and opposite phase meet, they cancel each other out, resulting in destructive interference.

When two waves of equal amplitude and opposite phase combine, they cancel each other out, resulting in destructive interference.

When light passes through a polarizer and then an analyzer at 90 degrees, no light passes through due to the orthogonal orientation.

Mixing equal volumes of 0.1 M HCl and 0.1 M NaOH results in a neutral solution with pH = 7.

The equal volumes of HCl and NaOH will neutralize each other, resulting in a pH of 7.
