Let's go through each question visible in the image:

1. Q7: "What is each angle size in a triple junction?"
   Answer: 120°.
   A triple junction occurs when three angles meet at a point. Since the sum of angles around a point is 360°, dividing that by 3 gives 120° per angle.

2. Q8: "6 - 5/8 = 5.375"
   This is a subtraction of a fraction from a whole number. The result, 5.375, is correct. Converting 5/8 to decimal gives 0.625, and subtracting from 6 results in 5.375.

3. Q9: "Find 400% of $40."
   Answer: $160.
   400% of a number is 4 times the original number. So, $40 \times 4 = 160$.

4. Q10: "A quadrilateral with two pairs of congruent adjacent sides is called a kite."
   Answer: Kite.
   A kite is defined as a quadrilateral with two distinct pairs of adjacent sides that are congruent.

5. Q11: "The volume of a coffee tin 10 cm deep and 20 cm in diameter is ______ cm³."
   To calculate the volume of a cylindrical object:
   Volume = π × r² × h, where r is the radius and h is the height.
   Here, the diameter is 20 cm, so the radius is 10 cm. The height (depth) is 10 cm.
   Volume = $\pi \times 10^2 \times 10 \approx 3141.59$ cm³.

6. Q12: "Is a triangle with sides of 3, 4, and 5 a Pythagorean triple?"
   Answer: Yes.
   A Pythagorean triple consists of three positive integers that satisfy the equation $a^2 + b^2 = c^2$. For sides 3, 4, and 5:
   $3^2 + 4^2 = 9 + 16 = 25 = 5^2$, so the triangle is a Pythagorean triple.

7. Q13: "Two sisters share an inheritance of $1 million dollars by a ratio of 2:3. How much does each sister inherit?"
   The total ratio parts are $2 + 3 = 5$.
   The first sister receives $\frac{2}{5} \times 1,000,000 = 400,000$, and the second sister receives $\frac{3}{5} \times 1,000,000 = 600,000$.

Tip: When calculating volumes of 3D shapes like cylinders, always double-check your units to ensure consistency (e.g., cm for both height and radius).
