When we think of surface area - What real-life things do we think of?

Mathematics

zepelin [54]4 years ago

Answer:

One of my favorite examples is in starting a fire. You can't just hold a match to a log and expect it to work, even though the log and small twigs are the same material and have the same burning point. A cluster of small twigs and splinters bunched up together has a huge surface area compared to a log.

Step-by-step explanation:

6, 6, 3, 3, and 3

63,363
36,336

I just kept switching around the numbers till the sixes were separated by a factor of 1,000. This means that if the 6 is in a place, that if you multiply the 6 by 1,000, you'll get the place that the other 6 is in.

For 63,363, there is one 6 in the tens place and one in the ten thousands place. 60 x 1,000 = 60,000, which is where the first 6 is in. They are separated by x1,000. 

For 36,336, there is a 6 in the ones place and a 6 in the thousands place. 6 x 1,000 = 6,000, and there is a 6 in the thousands place. They are separated by x1,000.

(Hope the explanation helped!)

sergeinik [125]

Using the formulas:

A=hbb

2

A=s(s﹣a)(s﹣b)(s﹣c)

s=a+b+c

2

Solving for <em>hb</em>

hb=﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4

2b=﹣154+2·(15·17)2+2·(15·8)2﹣174+2·(17·8)2﹣84

Use the distributive property to write the following expression in expanded form.<br><br> 5(7h + 3m)
laiz [17]
<h3>hello!</h3>

==============================================================

The distributive property states that:-

\bigstar{\underline{\boxed{\pmb{a(b+c)=ab+ac}}}

Simplify:-

\bigstar{\boxed{\pmb{5(7h+3m)}}}

\longmapsto\sf{(5~times~7h)+)5*3m)

\longmapsto\sf{35h*15m}

===============================================================

<h3>note:-</h3>

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
