Jana wants to build a pyramid by stacking cups upside down on each other. If the top of the pyramid has 1 cup and the bottom of the pyramid has 6 cups, how many rows of cups are in Jana's pyramid?

Step-by-step explanation:

Given:

At the top:

1 cup

At the bottom:

6 cups

Using arithmetic progression,

First row, a = 1

Common difference = 1

Final row, an = 6

We are assuming n = number of rows.

Therefore the arithmetic progression, an = ao + (n - 1)d

Inputting values,

6 - 1 = n - 1

n = 6

= 6 rows.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
