Answer:

\large\boxed{\sf \ \ \ 1757 \ km^2 \ \ \  }

Step-by-step explanation:

Hello,

<em>I would recommend that you checked the answers I have already provided as this is the same method for all these questions, and maybe try to solve this one before you check the solution.</em>

<u>At the beginning the area is 2100</u>

<u>After one year</u> the area will be

   2100*(1-3.5%)=2100*0.965

<u>After n years</u> the area will be

   2100\cdot0.965^n

So after 5 years the area will be

   2100\cdot0.965^5=1757.34027...

So rounded to the nearest square kilometer is 1757

Hope this helps

Answer: 1757 km²

Step-by-step explanation:

Because 3.5% = 0.035, first do 1-.035 to get .965.  Then do 2100*.965*.965*.965*.965*.965 to get 1757.34027.

Sarah scored an 8/10 on the spelling test and Jonathan scored 75% of Sarah’s score on the spelling test. What is the score of Jo
Fudgin [204]

\frac{3}{5} is the score of Jonathan.

<h3 /><h3>What is percentage?</h3>

Percentage, which may also be referred to as percent, is a fraction of a number out of 100%. Percentage means "per 100" and denotes a piece of a total amount.

To calculate the percentage , Use the percentage formula:

X * \frac{Percentage}{100} = Y

According to the question:

Sarah scored on the spelling test  = \frac{8}{10}

Jonathan scored  = 75%

By formulating both the values;

\frac{8}{10}  * \frac{75}{100}

= \frac{3}{5}

Therefore , \frac{3}{5} is the score of Jonathan.

(5t^3)^-4<br><br> 1. 625/t^12<br> 2. 20/t^7<br> 3. 1/625t^12<br> 4. 1/20t^7
rusak2 [61]

Answer:

\large\boxed{3.\ \dfrac{1}{625t^{12}}}

Step-by-step explanation:

\text{Use}\\\\(ab)^n=a^nb^n\\\\(a^n)^m=a^{nm}\\\\a^{-n}=\dfrac{1}{a^n}\\---------------\\\\(5t^3)^{-4}=\dfrac{1}{(5t^3)^4}=\dfrac{1}{5^4(t^3)^4}=\dfrac{1}{625t^{(3)(4)}}=\dfrac{1}{625t^{12}}
