The line segments labeled 8, 9, and form a right triangle, so Pythagoras' theorem holds:
None of the provided choices are correct...
This can be solved using the Combined Gas Law. The formula for that is
Let's go ahead and fill in our known values. Since pressure remains the same, it doesn't matter what number we use, so let's assume 1 atm on both sides. For temperature, remember to convert it to Kelvin first (K = C + 273).
Go ahead and simplify both sides.
Multiply both sides by 573.
0.7095 = x L
So, at 300° C, your gas will occupy 0.7095 L.
This problem can be solved using the Combined Gas Law. The formula for it is
Let's go ahead and plug in the known values. Since pressure remains the same, it does not matter what value we plug in, so let's assume 1 atm for both sides.
Now, we just need to solve for the unknown. Start by simplifying the left side and right numerator.
Multiply both sides by x.
0.001x = 0.140
Divide both sides by 0.001.
x = 140 K
Convert that to Celsius (K = C + 273)
140 = C + 273
C = -133
So, the volume of your gas will be 0.140 L at -133° C.
the remaining unknown angle = 180-90-45 = 45deg.
so the right-angled triangle is also isosceles
the remaining unknown side = 6
Any questions? Hope this helps!
There is a theorem which states equal angles in a triangle have their opposite sides equal...hence base is also 6 ...then by Pythagoras Theorem x=√72=6√2
16.60 - 12.45 = 4.15m
The height is 1.65m, set up a proportion:
Divide 4.15 to both sides:
So the height of the flagpole is 6.6 meters tall.
