Explanation

Frogs typically have 26 chromosomes in their body cells.

The number of chromosomes is species-specific and helps in maintaining genetic stability.

Explanation

To divide (2x^3 - 5x^2y + 5xy^2 - 3y^3) by (2x - 3y), let's attempt polynomial long division or factorization if possible.

Given the form of the dividend and divisor, let's try to factor or directly apply division:

(2x^3 - 5x^2y + 5xy^2 - 3y^3) ÷ (2x - 3y)

Upon inspection or performing polynomial division, one notices:

2x^3 - 5x^2y + 5xy^2 - 3y^3 can be factored or divided as follows:

2x^3 - 3x^2y - 2x^2y + 3xy^2 + 2xy^2 - 3y^3

Which can be rearranged and factored:

x^2(2x - 3y) - xy(2x - 3y) + y^2(2x - 3y)

= (2x - 3y)(x^2 - xy + y^2)

Thus, (2x^3 - 5x^2y + 5xy^2 - 3y^3) ÷ (2x - 3y) = x^2 - xy + y^2

Explanation

The correctly rearranged sentence is: "He always does his homework."

This sentence follows the proper word order for English grammar.

Explanation

Elaboration involves connecting new information to existing knowledge to deepen understanding.

It enhances memory retention by creating meaningful associations between ideas.

Explanation

L = length, W = width

Perimeter = 2(L + W) = 34 cm

If length increases by 2.5 cm:

New perimeter = 2(L + 2.5 + W)

= 2L + 5 + 2W

= 2(L + W) + 5

= 34 + 5

= 39 cm

Difference in perimeter = 39 - 34 = 5 cm

Explanation

A star with an initial mass between 1 to 5 times the solar mass expands into a red giant and then collapses into a white dwarf.

A white dwarf is a dense, Earth-sized remnant of a star that has exhausted its nuclear fuel.

Explanation

Chandragupta Maurya was the founder of the Maurya Empire.

He established the first centralized government in the Indian subcontinent.

His empire included Gandhara, which is present-day northern Pakistan and parts of Afghanistan.

Explanation

The total surface area (TSA) of a cylinder is given by:

TSA = 2πr(h + r)

Given:

h = 12.4 cm

r = 2.1 cm

TSA = 2 * π * 2.1 * (12.4 + 2.1)

= 2 * 3.14159 * 2.1 * 14.5

≈ 2 * 3.14159 * 30.45

≈ 191.226

Explanation

Explanation

To find the cost of painting, we need to calculate the surface area of the cuboid:

Surface Area = 2(lw + lh + wh)

= 2(43.5 + 46 + 3.5*6)

= 2(14 + 24 + 21)

= 2 * 59

= 118 square meters

Now, cost of painting:

Cost = Surface Area * Rate

= 118 * 43.78

= 5166.04
