Answer:
Step-by-step explanation:
Summation means that you are adding together all the numbers that result from putting in the numbers 5-11 for i:
(-7 - 6(5)) + (-7 - 6(6)) + (-7 - 6(7)) + ( -7 - 6(8)) + ( -7 - 6(9)) + ( -7 - 6(10)) + ( -7 - 6(11)) which gives you the numbers:
-37 + -43 + -49 + -55 + -61 + -67 + -73 = -385
Step-by-step explanation:
Area=Length×width
=6 5/7×7 3/5
change the improper fraction to proper
=47/7 ×38/5
=1786/35
=51.03ft²
The formula is SA =

. r is the radius and l is the slant height. In your case it would be

.

First off, why is this in the mathematics section lol. Anyways, the essay looks good, but you can remove some unnecessary information. The reader doesn't need to know that the author is 14. Knowing the age of an author won't help support your argument.
Also, you say, "For example during the pandemic situation there were some quick changes to it like the vaccines being made...".
I would say instead, "During the pandemic, there were some rapid changes that took place to correct the pandemic like the vaccines being made...". Other than that, the essay looks good!
