Answer:

A = 3 B = 180

Step-by-step explanation:

First you do 21/4 divided by 7/4 = 3. So 3 equals how many batches. Now since 5 dozen cookies in each batch and a dozen equals 12 cookies there are 60 cookies in each batch and since there are 3 batches you would do 60 * 3 = 180.

I’m sure this is easy but i'm gonna ask anyway
Arada [10]
No, it's always okay to ask if you don't understand a question.  Anyway, for this problem, we just have to plug in the value for <em>V </em>to solve for <em>P</em> :

P = 4V^{ \frac{1}{3}} \\ P = 4(125)^{ \frac{1}{3}}

A number to the power of 1/3 is the same as taking a cube root.

P = 4(125)^{ \frac{1}{3}} \\ P = 4(5) \\ P=20

The perimeter of one face of the cube is 20m.

Write the following series in sigma notation.<br> 7 + 16 + 25 +34 +43 +52 + 61
Solnce55 [7]

The series 7 + 16 + 25 +34 +43 +52 + 61 is an illusration of arithmetic series

The sigma notation of the series is: \sum\limits^7_{n=1} {9n - 2}

<h3>How to write the series in sigma notation?</h3>

The series is given as:

7 + 16 + 25 +34 +43 +52 + 61

The above series is an arithmetic series, with the following parameters

  • First term, a = 7
  • Common difference, d = 9
  • Number of terms, n = 7

Start by calculating the nth term using:

a(n) = a + (n - 1) * d

This gives

a(n) = 7 + (n - 1) * 9

Evaluate the product

a(n) = 7  - 9 + 9n

Evaluate the difference

a(n) = 9n - 2

So, the sigma notation is:

\sum\limits^7_{n=1} {9n - 2}
