Hamster is 8%, fish 12% and dogs are 23%. i added them together and got 0.43%. the question is- the citizens of a certain community were asked to choose their favorite pet. the pie chart below shows the distribution of the citizens' answers. if there are 100,000 citizens in the community, how many chose hamsters, fish, or dogs?

43,000 Citizens

Step-by-step explanation:

Data

Hamster    8%

Fish          12%

Dogs  23%

Sum        43%

The total population is 100,000 citizens. To find the number of citizens for each pet obtain the percentage of 100,000:

Citizens who chose hamsters are  8% of 100,000

100,000*8/100=8,000

Citizens who chose fish are  12% of 100,000

100,000*12/100=12,000

Citizens who chose dogs are  23% of 100,000

100,000*23/100=23,000

Citizens who choose hamsters, fish or dogs, is the sum of these three results

8,000+12,000+23,000=43,000

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
