Answers

Answer 1

Answer: Well basically the formula for the area of the circle is pi r squared. First you square 3 which is 9 and then you times it by 3.14 which gives you 28.26.Hope this helps!

$a_6=8;\ a_(10)=13\n\na_(10)-a_6=4r\n\n4r=13-8\n4r=5\ \ \ \ /:4\nr=1.25\n\na_1=a_6-5r\na_1=8-5\cdot1.25=8-6.25=1.75\n\nS_4=(2a_1+(4-1)r)/(2)\cdot4=(2a_1+3r)\cdot2=4a_1+6r\n\nS_4=4\cdot1.75+6\cdot1.25=7+7.5=14.5$

Final answer:

The sum of the first 4 terms of the arithmetic sequence where the 6th term is 8 and the 10th term is 13 is 14.5.

Explanation:

In an arithmetic sequence, the difference between consecutive terms is constant. This difference is commonly called the common difference. Given that the 6th term is 8 and the 10th term is 13, we can calculate this common difference.

The common difference is (13 - 8) / (10 - 6) = 5 / 4 = 1.25.

The common difference is backward from the 6th term to the first term or we can say the 6th term minus 5 times the common difference will give us the first term. Therefore, the first term is 8 - 5*1.25 = 8 - 6.25 = 1.75.

The sum of the first 4 terms of an arithmetic sequence is given by the formula S = n/2 *[2a + (n-1)*d], where 'n' is the number of terms (in this case 4), 'a' is the first term, and 'd' is the common difference.

Therefore, substituting our known values into the formula gives us: S = 4/2 *[2*1.75 + (4-1)*1.25] = 2*[3.5 + 3.75] = 2*7.25 = 14.5

Melissa plans to purchase a pair of jeans for $39.95. She wants to bring enough money to pay for the jeans plus the sales tax, which is 8.25%. What is her total, including sales tax?

Answers

You have to calculate the 8.25% of $39.95, then add the numbers together.
So: 8.25% of 39.95 = 3.3 (approximately)
The total is 39.95 + 3.3 = 43.25

Another method is to simply calculate the 108.25% of 39.95, you can get this by multiplying 39.95 with 1.0825.
