Answer:
The rectangular 5 x 10 table.
Step-by-step explanation:
To find which table the office manager needs to get so he can sit more people at it is decided by one factor, the perimeter. The rectangular one, which is 5 x 10 the perimeter is (5 x 2) + (10 x 2) = 10 + 20 = 30. The circular one can be calculated by the equation
where d = 8. Putting 
x 8 in my calculator and it comes out approximately at 25.132, having a less amount of perimeter space to work with, making the rectangular table the way to go.

Answer:
- 1 5/24 cm
Step-by-step explanation:
We'll have to get the fractions to a common denominator. the least common denominator for 3 and 80 is 240.
So - 1 1/3 = - 1 80/240 = 320/240
21/80 = 63/240
-11/80 = -33/240
-------------------------------------
-320/240 + 63/240 - 33/240 = -290/240 = - 1 50/240 = -1 5/24 cm
Answer:
The jetski is 2.28 dB loud when the person is 41 feet away.
Step-by-step explanation:
Loudness (L) ∝ 1 / Distance² (d²)
Introduce a constant 'K'
L = K (1/d²)
L = K/d²
K = Ld²
Find the K from a previously known information: If a person 8 feet from a jetski hears 60 decibels loud
∴ d = 8 ft , L = 60 db
K = 60(8²) = <em>3840</em>
How loud is the jetski when the person is 41 feet away?
Distance is now 41 ft
since: L = K/d²
∴ L = 3840 / 41²
L = 3840 / 1681
L = 2.28 db
