Answer:

Answer is 225.

We have to find the sum of 15 terms of the series

sigma 1 to 15 (2n-1)

This can be split as per summation terms as

sigma 2n - sigma 1

sigma 2n can again be simplified by taking 2 outside

sigma 2n= 2 times sum of natural numbers of 1 to 15

= 2(15)(16)/2= 240

sigma 1= 1+1+...15 times= 15

Hence final answer is

= 2 times sigma n - (n) = 240-15 = 225.

Question 2) Answer

Use Arithmetic Series Formulas:

a) Nth term = F + (N - 1) x D, where F=First term, N=Number of terms, D=Common difference

6th row = 23 + (6 - 1) x -3

            = 23 + (5) x -3

            = 23 + (-15)

            = 8 - number of boxes in the top row.

b) Sum = N/2[2F + (N - 1) x D]

            = 6/2[2*23 + (6 - 1) x -3]

             = 3  [46  +    (5) x -3 ]

             = 3  [46  +      -15 ]

             = 3  [ 31 ]

             = 93 - total number of boxes in the entire display.

Question 3) Answer


Sum of the 8 first terms of the geometric progression with the first term 50 and the common ratio of 2:


=50 + 5*2 + 50*2^2 + . . . + 50*2^7

= 50*(1 + 2 + 2^2 + . . . + 2^7) = 50*(2^8-1)

= 50*(256-1) = 50*255

= 12750 Answer


I am also attached the solved question of this assignment please check and enjoy. Thanks

Package A contains 3 birthday cards and 2 thank you notes and costs $18. Package B contains 8 birthday cards and 6 thank you not
Karo-lina-s [1.5K]
Two equations can be generated from the equation above, one for Package A and the other for Package B.
 
                 (Package A)      3x + 2y = 18
                 (Package B)      8x + 6y = 50

Solving simultaneously for the values of x and y gives, x = 4 and y = 3. Hence, each birthday card costs $4.

How do you write 1.3 × 105 in standard form?
emmainna [20.7K]

Given:

The scientific notation of a number is 1.3\times 10^5.

To find:

The standard form of the given number.

Solution:

Standard form: The normal way of writing a number is called standard form. For example: 200, 25600, 1025000 etc.

We have,

1.3\times 10^5

It can be written as

1.3\times 10^5=1.3\times 100,000

1.3\times 10^5=130,000

Therefore, the standard form of the given number is 130,000.

Tony purchases 12 water bottles. Of those bottles, 5 hold 400 milliliter each and 7 hold 1.5 liters each. How much water, in mil
Rashid [163]

Answer:

12 L 500 mL

Step-by-step explanation:

First, multiply the two types of bottles separately.

5 × 400 = 2000 mL

7 × 1.5 = 10.5 L

You can convert the volume of the first from milliliters to liters.  There are 1000 milliliters in 1 liter.  In the second volume, you can convert the decimal to milliters.

2000 mL = 2 L

0.5 L = 500 mL

Add all of the numbers together.

10 L  +  2 L  +  500 mL  =  12 L 500 mL

Tony purchased 12 L and 500 mL of water.
