The answer is II and III, which is the last choice from above. This is because the symbol "less than (or equal to)" indicated a conjunction, which means we have to take into account that the absolute value can be less than or equal to 15, and greater than or equal to -15. This solution set falls in between the two values, hence, the conjunction.

A certain kind of bacteria growing on your kitchen counter doubles every 30 mins.. Assuming that you start with only one bacteri

natali 33 [55]

What you can do is start with the key details in it... the main ones are that the bacteria grows every 30 minutes, you start with 1 bacteria, and the end time is 180 minutes. Basically you know that 3 goes into 18 6 times so 30 goes into 180 6 times which means that if you started with 1 bacteria you will end up with 7. Understand?

Answer:

96 $cm^3$

Step-by-step explanation:

To determine how much additional wax was needed to make the taller candle, we determine the volume of each of the candles and find the difference in their volumes

<u>First Candle</u>

Height=12cm
Length=4 cm
Width= 6 cm

Volume=Height X Length X Width

=12 X 4 X 6

=288 $cm^3$

<u>Second Candle</u>

The second candle is 4cm higher

Height=12+4=16cm
Length=4 cm
Width= 6 cm

Volume=Height X Length X Width

=16 X 4 X 6

=384 $cm^3$

Difference in Volume = 384-288 =96 $cm^3$

Therefore, 96 $cm^3$ of additional wax was used to make the second candle.
