Answer:
368 sq. units.
Step-by-step explanation:
We have a square of side lengths 20 units and we cut four congruent isosceles right triangles from the corners of the square.
Now, the four isosceles right triangles have one leg equal to 4 units.
Therefore, the area of four triangles = sq. units.
Now, we have the area of the given square is (20 × 20) = 400 sq. units.
Therefore, the area of the remaining octagon will be (400 - 32) = 368 sq. units. (Answer)
Answer:
The average salary of master's degree people is $ 63,000 And
The average salary of bachelor's degree people is $ 52,000
Step-by-step explanation:
Given in question as :
Let the average salary of master's degree people = $ M And
Let the average salary of bachelor's degree people = $ B
According to question ,
The average salary of master's degree people + The average salary of bachelor's degree people = $115,000
Or , $ M + $ B = $ 115,000 ............. A
Again ,
$ M = 2 × $ B - $ 41,000 ............... B
From eq A and eq B
(2 × $ B - $ 41,000 ) + ( $ B ) = $ 115,000
Or, 3×$ B = 156,000
∴ B = = $ 52,000
And M = $ 115,000 - $ 52,000
∴ M = $ 63,000
Hence The average salary of master's degree people is $ 63,000 And
The average salary of bachelor's degree people is $ 52,000 Answer
