To calculate the interest on a bank loan, use the formula: Interest = Principal × Rate × Time. Here, the principal is ₱30,000, the annual interest rate is 12% (or 0.12), and the time is 8 months (or 8/12 years).

Calculating:
Interest = ₱30,000 × 0.12 × (8/12) = ₱30,000 × 0.12 × 0.6667 = ₱2,400.

Thus, the interest paid on the loan for 8 months at the specified rate is ₱2,400.

To find the total area of Hacienda Tress, multiply the number of tenants by the area awarded to each tenant. Since there are 22 tenants and each receives 6 hectares, the calculation is 22 tenants × 6 hectares/tenant = 132 hectares. This total area represents the entire land that is being divided among the tenants.

Charles Darwin is renowned for his groundbreaking work, "On the Origin of Species," published in 1859. In this book, he presented the theory of evolution by natural selection, arguing that species evolve over time through a process where traits that enhance survival and reproduction become more common in successive generations. This work fundamentally changed the understanding of biology and laid the foundation for modern evolutionary theory, making Darwin a pivotal figure in the history of science.

Light travels at its highest speed in a vacuum because it does not encounter any medium to impede its motion, allowing it to reach approximately 299,792 kilometers per second. In contrast, sound requires a medium (solid, liquid, or gas) to propagate, and it travels fastest in solids due to the close molecular arrangement, which facilitates quicker energy transfer. Thus, while light's speed is maximized in a vacuum, sound's speed is maximized in solids.

To simplify the expression, start with the innermost parentheses: \(7y - 6x\) simplifies to \(7y - 6x\). Then, substitute this back into the expression, yielding \(2x - (3y - [5x - (7y - 6x)])\). Distributing the negative sign throughout the brackets and combining like terms leads to \(2x - 3y + 5x + 6x - 7y\). Collecting all \(x\) and \(y\) terms gives \(13x + 10y\). Thus, the final simplified expression is \(13x + 10y\).

The p-sublevel consists of three orbitals, each capable of holding a maximum of two electrons with opposite spins. Since there are three orbitals (px, py, and pz) in the p-sublevel, the total capacity is calculated as 3 orbitals multiplied by 2 electrons per orbital, resulting in a maximum of 6 electrons. This configuration is part of the broader principles of quantum mechanics and the structure of electron shells in atoms.

Mendel is considered the father of genetics due to his pioneering work with pea plants in the 19th century. Through meticulous experiments, he discovered the fundamental principles of heredity, including the concepts of dominant and recessive traits. His formulation of the laws of segregation and independent assortment laid the groundwork for modern genetics, establishing how traits are inherited from one generation to the next. Mendel's insights were largely unrecognized during his lifetime but later became foundational to the field, earning him recognition as a key figure in understanding genetic inheritance.

Emilio Aguinaldo, the first President of the Philippines, is recognized as the longest-living president, passing away at the age of 94. His long life spanned significant historical events, including the Philippine Revolution against Spanish rule and the subsequent American occupation. Aguinaldo's contributions to the country's independence and governance left a lasting legacy, and his longevity reflects not only his personal resilience but also the enduring impact of his leadership on Philippine history. His life and presidency are emblematic of the struggles and triumphs of a nation seeking sovereignty.
