This number represents the equal number of parts that equal a whole in a fraction

The denominator

Step-by-step explanation:

A fraction is composed of two elements, the nominator at the top and the denominator at the bottom.  

The numerator represents how many parts are divided.

The denominator represents the number of equal parts that make up the whole.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

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:
