You have seen it, a number with so many zeros that you are not sure where to start when reading it. it may be ginormous or teeny, teeny, way, it seems like it could be expressed in a manner easier to understand. in this discussion, your job is to find such a number–a number so big or so tiny that it is sure to confound your friends. round and rewrite your number so that it is in a power of 10.

example: my dad and i love to look at the night sky. i like to see how the moon changes as it moves. sometimes it is close and other times, it looks so far away. the moon's distance from the earth changes, but on average it is about 405,000 km away. the nearest power of 10 to this number would be 105.

example 2: the deepest part of the ocean is approxamately 36,200 feet. so, thats 10 to the 4th power.

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

step-by-step explanation: 4 cause 2+2=4
