Olivia is brewing tea. She starts boiling 0.455 L of water in a kettle. The change in volume of the contents of the kettle are noted below.

First, Olivia adds tea leaves. This increases the volume of the contents by 0.056 L.
After a few minutes of brewing, evaporation brings the volume down by 0.004 L.
Finally, Olivia pours herself a cup, which reduces the volume of the contents of the kettle by 0.168 L.
What is the volume of the contents of the kettle after Olivia pours herself a cup of tea?

0.227 L
0.287 L
0.339 L
0.347 L

answer: 7270

step-by-step explanation:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

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!
