However, the dosimeter is actually worn by the worker to determine the personal noise dose during the workshift or sampling period (Figure 21). Noise dosimetry is a form of personal sampling, averaging noise exposure over time and reporting results such as a TWA exposure or a percentage of the PEL.
Hello!
The ground, building and ladder are making a triangle, and since the ladder is tilted and is the longest side, it is the hypotenuse. We know how long the floor (leg) and ladder (hypotenuse) are. We need to solve for how tall the third floor window is from the ground. To do so we will use the Pythagorean Theorem (c²-b²=a²).
100-25=75
√75≈8.66
The third story window is about 8.66 meters from the ground.
I hope this helps!
<span>length = 7x
</span><span>width = 2x
2(7x + 2x) = 72
7x + 2x = 72/2
9x = 36
x = 36/9
x = 4
</span>
width = 2x = 2 * 4 = 8 units<span>

Answer:
A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.
Step-by-step explanation:
the additive inverses are basically opposite numbers. when you add a number to its additive inverse, it equals 0. example: -5 and 5...and 2 and -2.
