Amethod of estimating the number of people participating in a march is to assign someone to a spot on the sidewalk with the job of counting the number of marchers who pass in 1 minute. then multiply this number by the minutes it takes for all marchers to pass that spot. susan counts 500 people walk by her in one minute. marchers will take 25 minutes to all pass her. how many people are participating in the march?

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

answer: 7

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
