Elio is right in assuming the relationship between the height and the hours it burns is proportional.
Find the unit rate
14 ÷ 8 = 1.75 cm/h
Divide
21 ÷ 1.75 = 12
You can set this up as an algebraic equation to check the answer.
If the candle is 21 cm tall, it will burn for 12 hours.
Hope this helped you! :)
<span>The ratio of the corresponding side lengths of similar triangles is called the <u>scale </u>factor.
This means that </span><span> all the sides of the small figure are multiplied by the same number to obtain the lengths of the corresponding sides of the large figure.</span>
Answer:
Step-by-step explanation:
A square is a <u>shape that which all sides are equal</u>
<em>14 is one side of the square and to find the area of a square/rectangle, you do </em><u><em>length*width </em></u>
14*14=196
Answer: 84,300,000
Simply move the decimal place to the right 7 places
-7 + 4(n-1). Use this and plug in 10 for n, making it
-7 + 4(9)
-7+36
29
