Hello :
93-84 =84-75 = 75-66 = 66-57 = 9 ...( common diference of arithmetic <span>sequence )
Un = U1 + (n-1)d d= 9 and U1 = 57 n = 250
U250 = 57 +249(9) = 2298</span>
Answer:
471.24 m²
Step-by-step explanation:
Formula for curved surface area is;
A = 2πrh
We are given dimensions of a single pillar as;
Height; h = 7.5 m
Radius of base; r = 2.5 m
Thus;
A = 2π × 2.5 × 7.5
A = 117.81 m²
Since there are 4 pillars.
Total curved surface area is;
A_t = 4 × 117.81
A_t = 471.24 m²
Answer:
400 + 6x
Step-by-step explanation:
$400 cabin cost is fixed and doesn't change.
Food cost changes as there are more people so we can write it as 6x
Total cost is 400 + 6x
Measure of each side of a triangle can't be greater than the sum of the other two sides and can't be smaller than the difference between the two other sides. therefore the most appropriate choice is ~

Answer:
Project A: $55,000 Project B: $50,800 Contractor should choose project A
Step-by-step explanation:
The expected value of the project is the sum of products of profit and its probability:
In thousands, ...
A: (50×0.6) +(80×0.3) +(10×0.1) = 30 +24 +1 = 55 . . . thousand
B: (100×0.1) +(64×0.7) +(-20×0.2) = 10 +44.8 -4 = 50.8 . . . thousand
__
The contractor should choose Project A based on the expected value of profit.
