Solve for x.

1. 15.9

2. 12

3. 7.29

4. 20.8

5. 11.0

Step-by-step explanation:

We can use the Pythagorean Theorem to solve for x (a squared minus b squared equals c squared)

Example number 1 is solved by  17 squared - 6 squared equals 253

You do square root and get 15.90

Number 4 is you have to divide 24 by 2 because it is one of the sides

So it is 24 squared minus 12 squared

You find square root and get 20.80

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

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:
