⦁ Find the sum of the series . 15 sigma n=1, (2n-1) Show your work
sergejj [24]

Answer:

225

Step-by-step explanation:

The sum of this series is given by the formula:

S_n=\frac{n}{2}[2a+(n-1)d]

Where

S_n is the sum

a is the first term (we get this by plugging in n = 1 into "2n-1", we have 2(1) - 1 = 1)

n is the number of terms (the sum is defined for n = 1 to n = 15, so 15 terms)

d is the common different (the difference is successive terms. Here, 2nd term would be 2(2) - 1 = 3, and first term was 1, so d = 3 -1 = 2)

<em>plugging in the info, we will get the sum:</em>

<em>S_n=\frac{n}{2}[2a+(n-1)d]\\S_{15}=\frac{15}{2}[2(1)+(15-1)(2)]\\=225</em>

<em>The sum is 225</em>

Frank is using a cookie recipe that calls for 2 ¼ cups of flour. The recipe yields 20 cookies. How much flour would be needed to
larisa86 [58]

Hey there! I'm happy to help!

How many times does 20 go into 48?

48/20=2.4

So, we multiply our amount of flour for 20 cookies by 2.4.

2.25×2.4=5.4

Therefore you would need 5.4 or 5 2/5 cups of flour to make 48 cookies.

Have a wonderful day! :D
