ANSWER REVEAL • QUESTION 01
LIFE SCIENCE
C
Correct Answer
Mitochondria

QUESTION 02 OF 15
What is the solution for \(x\) in the two-step equation: \(4x - 7 = 25\)?
A \(x = 6\)
B \(x = 8\)
C \(x = 9\)
D \(x = 5\)
Work out your steps on paper!
ANSWER REVEAL • QUESTION 02
PRE-ALGEBRA
B
Correct Answer
\(x = 8\)
Step-by-Step Solution
Step 1 (Inverse Addition): Add \(7\) to both sides of the equation: \(4x - 7 + 7 = 25 + 7 \implies 4x = 32\).
Step 2 (Inverse Division): Divide both sides by \(4\): \(\frac{4x}{4} = \frac{32}{4} \implies x = 8\).

QUESTION 05 OF 15
What geological process occurs when a denser oceanic tectonic plate collides with and sinks underneath a continental plate into Earth's mantle?
A Divergence
B Subduction
C Sea-Floor Spreading
D Transform Sliding
This process often creates deep ocean trenches!
ANSWER REVEAL • QUESTION 05

Plate Tectonics Review
At convergent boundaries, the heavier basaltic oceanic crust sinks into the asthenosphere at a subduction zone, forming trenches (like the Mariana Trench) and chains of volcanoes (like the Pacific Ring of Fire).

MATHEMATICS • GEOMETRY
QUESTION 06 OF 15
A right triangle has legs with lengths of \(6\text{ cm}\) and \(8\text{ cm}\). What is the exact length of the hypotenuse?
A \(10\text{ cm}\)
B \(12\text{ cm}\)
C \(14\text{ cm}\)
D \(16\text{ cm}\)
Hint: Recall \(a^2 + b^2 = c^2\)
ANSWER REVEAL • QUESTION 06
GEOMETRY
A
Correct Answer
\(10\text{ cm}\)
Pythagorean Theorem Proof
Formula: \(a^2 + b^2 = c^2\)
Substitute: \(6^2 + 8^2 = c^2 \implies 36 + 64 = c^2 \implies 100 = c^2\)
Take the square root: \(c = \sqrt{100} = 10\text{ cm}\). (This is a 3-4-5 Pythagorean triple scaled by 2!)

Identify which subject performs the action directly!
ANSWER REVEAL • QUESTION 07
GRAMMAR & STYLE
C
Correct Answer
Maya discovered a rare mineral inside the canyon.
