Carmen is playing with blocks. She arranges stacks of blocks so that each successive level of blocks how 1 fewer block than the block below it and the top level has 1 block. Such a stack with 3 levels shown is below. Carmen wants to make a such a stack with 12 levels. How many blocks would she use to build this stack?

what is the information provided?

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
