First, we determine the volumes of the posts may it be cylindrical in shape or rectangular prism.
(A) cylindrical:
( π(26.7/100)² - π(24.2/100)²)*(7.5) = 0.3 m³
(B) rectangular prism:
(40/100)²(7.5) - (35/100)²(7.5) = 0.28125 m³
Then, we calculate for the amount of substance
(A) cylindrical: (0.3 m³)(2700 kg/m³) = 810 kg
(B) rectangular prism : (0.28125 m³)(2700 kg/m³) = 759.375 kg
Then, calculate for the costs
(A) (810 kg)($0.38/kg) = $307.8
(B) (759.375 kg)($0.38/kg) = $288.56
Thus, the answer for A is rectangular post
B. About $19.24 can be saved.
The answer is 23 because you would substitute in the 4 for the X and multiply 5 times 4 = 20 then add 20 plus 3 and you get 23
Answer:
NO triangle exists.
Step-by-step explanation:
Given that the sides of the triangle are a=43 ,b=82 , and c=28
To solve for unknown angles of the triangle
PLease refresh the triangle rule of inequality that the sum of any two sides is always greater than the third side
Before solving the triangle, let us check whether this is true.
a+b >c
b+c>a
But a+c is not greater than b.
Hence there cannot be any real triangle with these sides given.
Answer is no triangle exists.
