Answer:
12 hours
Step-by-step explanation:
Create a proportion where x is how long the 21 cm candle can burn for:
= 
Cross multiply and solve for x:
14x = 168
x = 12
So, the 21 cm tall candle can burn for 12 hours
Are you asking a question or are you just making a statement?
The answer is A. ( reflection over the x-axis ) because the points start in quadrant 1 and when you flip those points across the x-axis they land in quadrant 3. hope this helps !!
Answer:
9.2
Step-by-step explanation:
you get 9.1651513... but it says round to the nearest 10th which would be 9.2
<em>Directed numbers</em> are numbers that have either a <u>positive</u> or <u>negative </u>sign, which can be shown on a <em>number line</em>. Therefore, point F is Fifteen-halves of line <em>segment</em> DE.
A <u>number line</u> is a system that can show the positions of <em>positive</em> or <em>negative</em> numbers. It has its <em>ends</em> ranging from <em>negative infinity</em> to <em>positive infinity</em>. Thus any <em>directed</em> number can be located on the line.
Directed numbers are numbers with either a <u>negative</u> or <u>positive </u>sign, which shows their direction with respect to the <em>number line.</em>
In the given question, the <u>distance</u> between points D and E is <em>9 units</em>. So that <em>dividing</em> 9 units in the ratio of 5 to 6, we have;
x 9 = 
= 
Therefore, the <em>location</em> of point F, which <u>partitions</u> the directed line segment from d to E into a 5:6 ratio is
. Thus the<em> answer</em> is <u>Fifteen-halves.</u>
