Explanation

Step 1: Find the total amount

Let the total amount be x.

20% of x = 150

0.20x = 150

x = 150 / 0.20

x = 750

Step 2: Calculate 26% of the amount

26% of 750 = 0.26 × 750 = 195

Explanation

x - 1/x = 4

Square it:

x² - 2 1/x² = 16

Add 2:

x² + 1/x² = 18

Explanation

"But" is used to show a contrast between two ideas — here, talent vs. lack of confidence.

It correctly connects the opposing thoughts in the sentence.

Explanation

The discriminant D = b^2 - 4ac = 1^2 - 4(4)(1) = 1 - 16 = -15.

Since D = -15 < 0, the roots are Imaginary and unequal.

Explanation

The hypocenter is the point inside the Earth where the rocks break, causing an earthquake.

The point directly above the hypocenter on the surface is called the epicenter.

Explanation

Qualitative research explores the underlying reasons and meanings behind teaching methods and experiences.

It involves descriptive analysis, interviews, and observations to understand educational practices deeply.

Explanation

A star with an initial mass more than five times that of the Sun ends its life as a black hole after a supernova explosion.

Its gravitational pull becomes so strong that not even light can escape.

Explanation

After cytokinesis, daughter cells enter interphase, the phase where they grow to normal size and prepare for the next division.

Interphase includes G1 (growth), S (DNA replication), and G2 (preparation for mitosis) stages.

Explanation

Calculate the cube root of 32768.

³√32768 = ³√32³ = 32

Explanation

When rotating a point (x, y) 90° counterclockwise, the new coordinates are (-y, x).

For P(-5, -3), the new coordinates P' will be (3, -5).
