The following chart shows a store's records of sales of stuffed toys for two months
Dmitry_Shevchenko [17]

Answer:

None of the above answers

Step-by-step explanation:

Form a table as shown

Months         Teddy Bears    Rabbits     Cats    Horses    Others    Totals toys

September      225                275           245      260          199        1204

October           346                 308           186      297           285       1422

Trends

Cats decreased from 245 to 186

Others increased from 199 to 285,

285-199 = 86

percent increase was = increase/original quantity *100

86/199 *100 =43.22%

Total number of stuffed toys increased from 1204 to 1422

percent increase = (1422-1204)/1204 *100 = 218/1204 *100 =18.11%

Find the area created by the overlapping circles given the following information.
lara31 [8.8K]

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.

Identify the factors of x2 − 5x − 24.
lutik1710 [3]
This seems to look like a factoring question. When factoring, one must know that the second number is the sum of the two values multiplied by x, and the third number is what happens when one multiplies those two numbers. Using these definitions, one can conclude that  the correct answer is (x-8)(x+3)
