a. about 100,000 x 365 = 36,500,000 times a year except on leap year
b. about 1 time per second (guessing at this one)
c. about 10 days because it takes 100,000 + 100,000 10 time to equal 1,000,000

a 100,000to the 365th power.
b 100 per second.

A. It is equal to 36,400,000, because you multiply 100,000 and 364 because that is how many day are in a year.

B. It is 166.1 becauce you divide 100,000 by 60.

C. 10 days because in one day it's 100,000. So you multiply that and you get your anwser.

For number 1 is 100,000 times 365=36,500,000.
For the second one is 100,000 times 60=6,000,000.
For number 2 is 100,000 times 7=700,000.

A. is 36,500,000 times because there is 365 days in a year times 100,000 to get 36,500,000.

B. is 40 time because if you take 60 seconds into 24 hours you get 40.

C. about 10 day because if you take 100,000 time 10 you get 1,000,000.

a. 36,500,000, because if you take 100,000 times 365 (days in a year) = 36,500,000

a. is 36,500,000 because there are 365 days in a year so i took 365* 100,000.

B. is somethig but i can't figure it out because i took 100,000/ by three and it gave me a huge amount of movements so i cant get it

364 days because there are only 365 days in a year when theres leap year

c. in about 10 years

Anonymous said...

a. 36,600,000 seconds in a year becuse you take the # of days times # of seconds per day
b. 166.7 becuse 100,000/60=166.7
c. 10 days because 100,000 power of 10 is 1,000,000

Anonymous said...

a. 36,900,000 a year, because you have to multiply 100,000 by 369 and you get 36,900,000

b. about 1.2 times becaue you have to figure out how much seconds are in a day and divide it by 100,000

c. 10 days, because you divide 1,000,000 by 100,000 and you get 10

a. 36,500,000 because you take 365 (thats how may days are in a year) and then you multiply that together and get that

b.about 1 time time Beacause I took 100,000 divided by 24 (hours in a day) and got 4,166 and then I divided that by 60
(minutes in a day) then I got 69 then I divided that by 60 (seconds in a day) and got my answer of 1

c. 10 daysyou multiply 100,000 by 10 and you get 1,000,000

A= 3,650,000
Because you take 100,000 ( how many times you blink) times 365 ( days in a year) and that's what you get.
B= 1-3 Because a second isnt that long and you cant move it a million times a second because it's just not possible
C= 10 days because 100,000 times 10 is a million and you make 100,000 movments each day

Okay. First ot find out how many times it moves a year you have to know how may days are in a year. There are 365 days in a year, so you take 365x100,00. You get 36500000. thats how many times it moves in a year. (a)3650000.
For b you have to take 100000 / by how many seconds are in a day and that is 8640 seconds in a day. then you divide 10000 by 8640. that is your answer. (b) 11.57. For C you take 1,000,000 / by 100,000 and thats your answer for c. (c)10 days.

Anonymous said...

For the first answer how many times in a year I took 100000 times 365 and got 36,500,00 as my answer. For the second one I got the answer 100,000 because 100,000 times 1 = 100,000. For the third question I got 10 days because 100,000 times 10 gives you 1,000,000.

Anonymous said...

the answer for a is about 3,000,000 because estimated 30 days each money so that time 100,000 is 3,000,000
b is 25 because 60 minutes in and hour so 100,000 / 60 then again is 25 estimated
c is 10 days because 10 x 100,000 is 1,000,000

you must multiply 365 by 100,000

B.100,000/24=4166 4166/60=69 69/60=1.15
so about 1 movement


C.100,000*10=1,000,000
it takes about 10 days to make 1,000,000 movements

c.1,000,000/100,000=10 days

Anonymous said...

A. The answer is 36,500,000 because you take 100,000 x 365 because there are 365 days in one year and you get your answer.
B. There are 24hrs. in 1 day, 60min. in 1 hour, and 60sec. in 1 min. So you take 24 x 60 x 60 = 86,400 per sec. Then you take 100,000 - 86,400 = 13,600 movements per sec. is your answer.
C. The answer is 10 days because you take 1,000,000 divided by 100,000 = 10 days and that will make 1,000,000 movements is the answer.

A) in one year it moves 36,500,000 times because you have to take 100000 x 365 because that's how many days are in a year, and you get 36,500,000.
B) you have to find out how many seconds are in a day, so we know that there are 24 hrs in a day and there are 60 minutes in a hour, so you take 24 x 60 and you get 1440 minutes in a day and there are 60 seconds in a minute so you take 1440 x 60 and get 86400 so that's how many seconds are in a day and you take 100000 and divide by 86400 and you get 1.1574 and you round to the nearest tenth and get 1.2 and that's how many times it turns in one second.
C) in ten days your eye muscle will make 1000000 movements because you take 1000000 and divide by 100000 and you get 10 so it will take 10 days.
