In what year were there 0.5 as many states as today? year states 1792 15 1817 20 1836 25 1848 30 1863 35 1889 40 1896 45 1959 50

OpenStudy (anonymous):

i don't understand the question, clarify

OpenStudy (anonymous):

the table unit shows the number of states in the u.s. at different times in history. There are currently 50 states in the u.s. Use the info to answer the questions

OpenStudy (anonymous):

also what percent of the current number of states had joined the u.s. by the year 1863?

OpenStudy (anonymous):

in your question you mean 1/2 right

OpenStudy (anonymous):

.5 is = to half i guess

OpenStudy (anonymous):

if there are 35 states at 1863 then 70% of the states had joind by 1863

OpenStudy (anonymous):

if there are 50 states what year equals 50=2x

OpenStudy (anonymous):

here's a clue 50=2(25)

OpenStudy (anonymous):

do you understand?

OpenStudy (anonymous):

OpenStudy (anonymous):

how did you get 70%

OpenStudy (anonymous):

there are 50 states right

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

so in 1863 there were 35 states, correct

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

35(current)/50(total)

OpenStudy (anonymous):

.7= 70%, right

OpenStudy (anonymous):

yes but how'd u come up with .7

OpenStudy (anonymous):

35(current)/50(total)

OpenStudy (anonymous):

divide 35/50

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

in what year were there about 2/3 as many states as in 1896?

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

what year did you get?

OpenStudy (anonymous):

1848, any other problems

OpenStudy (anonymous):

i still don't understand what to do with the fration

OpenStudy (anonymous):

r u in algebra

OpenStudy (anonymous):

OpenStudy (anonymous):

Wow, I didn't know people took algebra that early

OpenStudy (anonymous):

Take the fraction and mulitply by x

OpenStudy (anonymous):

its 30 1848 i think i got it

OpenStudy (anonymous):

good job, that's right any other problems

OpenStudy (anonymous):

yes 2 more please.............which of the following is equivalent to 98%....0.49, 100/98, 0.98, 49/100? explain how you would write 5/6 as a percent?

OpenStudy (anonymous):

which one do you think it is

OpenStudy (anonymous):

100/98

OpenStudy (anonymous):

r u sure

OpenStudy (anonymous):

no or .098

OpenStudy (anonymous):

i divided 98 into 100 and got .98

OpenStudy (anonymous):

OpenStudy (anonymous):

not sure

OpenStudy (anonymous):

OpenStudy (anonymous):

.98

OpenStudy (anonymous):

so by dividing 100/98 is the way to get the percent

OpenStudy (anonymous):

no, up above you told me that you divided 98 into one-hundred, 100/98 is more that one-hundred you divide 98/100 not 100/98 so the answer is .98

OpenStudy (anonymous):

okay i did it backwards

OpenStudy (anonymous):

exactly

OpenStudy (anonymous):

any other

OpenStudy (anonymous):

so 5/6=?% divide 6 into 5 =1.2

OpenStudy (anonymous):

no

OpenStudy (anonymous):

percent means per one-hundred percents above one-hundred means error 1.2= 120% you divide the denomintator by the numerator and that is the percent

OpenStudy (anonymous):

so what is the correct answer

OpenStudy (anonymous):

if i divide 6 into 5 i get 1.5

OpenStudy (anonymous):

i mean 1.2

OpenStudy (anonymous):

first of all if you devide 6 into 5 you get 1.2

OpenStudy (anonymous):

second of all you are doing the opposite of what i'm telling you

OpenStudy (anonymous):

try doing the exact opposite

OpenStudy (anonymous):

5 into 6 is .83333333333

OpenStudy (anonymous):

which means the percent is?

OpenStudy (anonymous):

just so you know 5/6 means 5 into six

OpenStudy (anonymous):

i don't know the formula

OpenStudy (anonymous):

what do you mean formula?

OpenStudy (anonymous):

83.3% rounded or 83 1/3% exactly

OpenStudy (anonymous):

100 into .83=120

OpenStudy (anonymous):

you aren't doing 100 into .83 you are doing 5 into 6

OpenStudy (anonymous):

5 into 6 is .83 .83 into 100 is 120

OpenStudy (anonymous):

if that's wrong im totally confused

OpenStudy (anonymous):

no it's not wrong why do you keep saying .83 into is 120 though that has nothing to do with this problem

OpenStudy (anonymous):

the problem says explain how to get 5/6 into a percent right

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

so step 1: divide 5 into 6 step 2: mulitply by 100 now, what is the answer?

OpenStudy (anonymous):

83

OpenStudy (anonymous):

yessssss

OpenStudy (anonymous):

do you understand how to find percents now

OpenStudy (anonymous):

if you need a formula it would be x/y=z z*100=percent

OpenStudy (anonymous):

wow it seems so hard yes i do thanks i should be able to finish and get a better grade so once i divide multiply by 100 thanks again

OpenStudy (anonymous):

yes i am glad to help I remember taking pre-algebra in seventh grade it was confusing for me to once i took algebra 1 it all started making sense as long as you do the hw and keep up you should do fine if there any more questions i would be glad to help
