Answer:

Option 3. (2π + 40) mm².

Step-by-step explanation:

Area of the composite figure = area of MKCD + area of ABCD + area of semi circle with AB as diameter.

Then Area A = (DC + MK)/2 × DN + AB² + (1/2)×π×2²

                     = (4 + 8)/2 × 4 + 4² + (1/2)×π×4

                     = 24 + 16 + 2π = (2π + 40) mm²

Therefore option 3. (2π + 40) mm².

Congruent means they are the same size 

To prove the two triangles are congruent you would need to know the length of at least two of the sides. If two sides were not known you would need to know the length of one side and at least one of the unknown angles.

Due to the economy and not wanting to eliminate any jobs, all state employees were asked to accept a 4.5% reduction in their sal
jeka94

Answer: The secretary's salary prior to the reduction was $42,000.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The original secretary's salary (x) multiplied by the percentage reduction in decimal form (4.5/100) must be equal to the amount of the reduction (1890)

Mathematically speaking:

x (4.5/100)= 1890

Solving for x:

x (0.045)= 1890

x = 1890/ 0.045

x = 42,000

The secretary's salary prior to the reduction was $42,000.
