Explain how you could use a hundred chart to find the missing number 63+? =87

Step-by-step explanation:

Alright, lets get started.

The given is :

Suppose the asked number is x, so

It means we need to find x.

If we subtract 63 from both sides, the give equation will become:

So the missing number is 24   :    Answer

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:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
