Answer:

745.44 square mm

Step-by-step explanation:

The figure can be decomposed into ...

a semicircle of radius 12.5 mm
a rectangle 12.5 mm by 25 mm
a triangle 12.5 mm by 30 mm

The relevant area formulas are ...

Semicircle: A = 1/2πr² = 1/2π(12.5 mm)² ≈ 245.437 mm²

Rectangle: A = LW = (12.5 mm)(25 mm) = 312.500 mm²

Triangle: A = 1/2bh = 1/2(12.5 mm)(30 mm) = 187.500 mm²

Total area of the figure is ...

245.437 +312.500 +187.500 = 745.437 . . . mm²

The area of the figure is about 745.44 square mm.

Part (i)

1) AB is perpendicular to BC, ED is perpendicular to CD, BC = CD (given)

2) Angles ABC and CDE are right angles (perpendicular lines form right angles)

3) Angles ABC and CDE are equal (all right angles are equal)

4) Angles ACB and DCE are equal (vertical angles are equal)

5) Triangles ABC and EDC are congruent (ASA)

Part (ii)

Jon, Leroy, and Simon are having a free-throw shooting contest. Each boy

Zolol [24]

Answer:

Step-by-step explanation:

If you arrange a statistics in order from least to greatest, the middle number is the median.

If there is even number of numbers in a list, let it be n numbers, then we take the average of n/2th and n/2 + 1 th terms.

Here, all of them have 6 numbers, so 6/2 = 3 and 4th, we take average of 3rd and 4th number to find the median.

Since they are arrange in order we check each:

Jon = average of 6 and 7, (6+7)/2 = 6.5

Leroy = average of 6 and 8, (6+8)/2 = 7

Simon = average of 5 and 6, (5+6)/2 = 5.5

Leroy's median is the greatest (7).
