Answer:
<h2>The total value of all the letters in the alphabet is 676.</h2>
Step-by-step explanation:
The problem is about an arithmetic sequence where the difference is 2, the first term is 1 and we know that the alphabet has 26 letters.
To find the total sum of all values, we have to use the following formula
Where 
, 
and 
. Replacing values, we have
Therefore, the total value of all the letters in the alphabet is 676.
A=2πrh+2πr2=2·π·6·25+2·π·6^2 so the answer is D
Answer:
2 bags of topsoil.
Step-by-step explanation:
The attached figure shows a flower bed.
One bag of topsoil covers 15 square meters.
We need to find how many bags of topsoil does Tom need to cover his flower bed.
The area of the flower bed is :
Let he has to cover x bags of topsoil. So,
x = Area of flower bed/Area of 1 bag of top soil
x = 30/15
x = 2
Hence, he will need 2 bags of topsoil to cover his flower bed.
You can figure out the answer by doing this:
8% = 2300/x
and do the same for the second one
(and solve)
CosB= 7/25
tanB= 24/7
sinB= 24/25
