Best ResponseYou've already chosen the best response.0How many significant figures would be re tained in the solution to [(2 + 0.0031) + (413 / 12)]×(2.45×1.83) = 1. three 2. two 3. zero 4. five 5. one 6. four

Best ResponseYou've already chosen the best response.0I know is not 5 even though the 2 is one digit

gahm8684

Best ResponseYou've already chosen the best response.0also know is not zero because there are numbers with higher digits than 0

Best ResponseYou've already chosen the best response.0and finally I know is not five just because

Best ResponseYou've already chosen the best response.0so my only possible answers are: number 1, or number 2

Best ResponseYou've already chosen the best response.1According to the link above the following information is relevant to your problem. When adding or subtracting numbers, count the NUMBER OF DECIMAL PLACES to determine the number of significant figures. The answer cannot CONTAIN MORE PLACES AFTER THE DECIMAL POINT THAN THE SMALLEST NUMBER OF DECIMAL PLACES in the numbers being added or subtracted. When multiplying or dividing numbers, count the NUMBER OF SIGNIFICANT FIGURES. The answer cannot CONTAIN MORE SIGNIFICANT FIGURES THAN THE NUMBER BEING MULTIPLIED OR DIVIDED with the LEAST NUMBER OF SIGNIFICANT FIGURES. This information tells exactly how to figure out the correct answer. Takes a bit of work on your part, but yes you can figure it out.

Best ResponseYou've already chosen the best response.0yeah I know, so the answer would be to solve the equation, and since the 2 has only 1 digit or significant figure the answer would be round to one digit

gahm8684

Best ResponseYou've already chosen the best response.0this means the equation would equal to 200

Best ResponseYou've already chosen the best response.1What equation? Equations have equal signs.

Best ResponseYou've already chosen the best response.1Explain how you went about eliminating options.

Best ResponseYou've already chosen the best response.0I tried #5, and it was wrong. I know that it is not five digits because there is no number with 5 digits, and if there was there is numbers with less digits.

Best ResponseYou've already chosen the best response.0and I'm not sure why it can't be three, two, or four digits

Best ResponseYou've already chosen the best response.1What was the result you got before rounding up to 200 (which you should not have done).

Hero

Best ResponseYou've already chosen the best response.1Mind showing how you got that step by step?

Best ResponseYou've already chosen the best response.0I plot the whole problem in the calculator

gahm8684

Best ResponseYou've already chosen the best response.0but I know I first would have to solve whats inside the keys

gahm8684

Best ResponseYou've already chosen the best response.0or i don't know what they are called in english

Best ResponseYou've already chosen the best response.1You have to perform each operation one step at a time while following the rules for significant digits.

gahm8684

Best ResponseYou've already chosen the best response.0alright so: ((2+0.0031)+(41/12)=40

gahm8684
 one year ago
Best ResponseYou've already chosen the best response.0because i had to round up

gahm8684
 one year ago
Best ResponseYou've already chosen the best response.0now I solve the whole thing 40×(2.45×1.83)=179.34

gahm8684

Best ResponseYou've already chosen the best response.0then I have to round up to 1 digit since 40 mis the lowest significant figure and it only has one digit

gahm8684
 one year ago
Best ResponseYou've already chosen the best response.0this means 179.34 rounds up to 200

Best ResponseYou've already chosen the best response.1You should follow ORDER of OPERATIONS. Multiply BEFORE adding from left to right.

Best ResponseYou've already chosen the best response.0(2 + 0.0031) + (413 / 12)]×(2.45×1.83) =[(2+0.0031)+(413/12)]x(4.4835)

gahm8684

Best ResponseYou've already chosen the best response.0is that what you meant?

Hero

Best ResponseYou've already chosen the best response.1Okay, yes, we should keep track of parentheses as well. You should have gotten 4.48 for (2.45×1.83)

gahm8684

Best ResponseYou've already chosen the best response.0oh right because there is 3 digits in there

Best ResponseYou've already chosen the best response.1The result can only be accurate to two decimal places.

Best ResponseYou've already chosen the best response.0[(2.0031)+(34.42)]x(4.4835)

Best ResponseYou've already chosen the best response.1The result of an operation can only be accurate to the number with the least amount of decimal places. In other words, you should not have decimal places when dividing whole numbers.

Best ResponseYou've already chosen the best response.0[(2+0.0031)+(34)]x(4.4835)

Best ResponseYou've already chosen the best response.0now I add the ones inside, right?

Hero

Best ResponseYou've already chosen the best response.1Yep, but add according to the rules.

gahm8684

Best ResponseYou've already chosen the best response.0the lowest is 2 thats why, so 2+34=36=40

Hero

Best ResponseYou've already chosen the best response.1What rule says to round 36 to 40?

gahm8684
 one year ago
Best ResponseYou've already chosen the best response.040 has only 1 digit. I rounded to one digit because of the two

Hero

Best ResponseYou've already chosen the best response.1How many significant figures does 4.48 have?

Hero
 one year ago
Best ResponseYou've already chosen the best response.1By the way, you shouldn't round 36 to 40.

Hero
 one year ago
Best ResponseYou've already chosen the best response.136 has two significant digits which means our result should have only two significant digtts.

Hero

Best ResponseYou've already chosen the best response.1The calculator does not know how to deal with significant digits unless you program it to do so.

gahm8684

Best ResponseYou've already chosen the best response.0but i guess there is some calculators that do, right?

Hero

Best ResponseYou've already chosen the best response.1Perhaps Wolfram Alpha does, but you would still have to use a special program for it. It won't do it automatically.

Hero

Best ResponseYou've already chosen the best response.1The calculator doesn't know you want to round to significant digits.
