320,000 / 3,840 = 730,000 / x
cross multiply because this is a proportion
(320,000)(x) = (3,840)(730,000)
320,000x = 2,803,200,000
x = 2,803,200,000 / 320,000
x = 8760 <====
Answer:
10 / 26
Step-by-step explanation:
cos <Z = adjacent / hypotenuse
= YZ / XZ
= 10 / 26
Dividend means the number to be divided, the divisor is the number you divide with.
It sounds like you just need to divide a three-numbered integer by a number between 10 and 20.
Example: Dividend --> 333÷16 <-- Divisor
The area of a circular sector of central angle α (in radians) in a circle of radius r is given by
... A = (1/2)r²×(α - sin(α))
Your area is expected to be computed as the sum of the areas of a sector with angle π/3 in a circle of radius 8 and a sector with angle π/2 in a circle of radius 6.
... A = (1/2)8²×(π/3 - sin(π/3)) + (1/2)6²×(π/2 - sin(π/2))
... A ≈ 16.07
Radii are in inches so the units of area will be in². The appropriate choice is
... 16.10 in²

It should be noted that the geometry described is impossible. Chord CD of circle A will have length 6√2 ≈ 8.4853 inches. Chord CD of circle B will have length 8 inches. They cannot both be the same chord.
