Answer:
x =
Step-by-step explanation:
given
=
( cross- multiply )
5(x + 1) = 33
5x + 5 = 33 ( subtract 5 from both sides )
5x = 28 ( divide both sides by 5 )
x =

Answer:
The diameter of the hole is 20.04 ± 0.01 cm
The diameter of the piston is 19.92 ± 0.04 cm.
We are given that The clearance is one-half the difference between the diameters.
So, Clearance =
=
Uncertainty in the estimate =
=
So, Clearance with uncertainty is
Hence the clearance is 0.06 and the uncertainty in the estimate. is 0.025
Check the picture below.
so, if we add all the arcs provided, we have a total of 153° + 60° + 53°, which gives us 270°.
keeping in mind that a circle has a total of 360°, the shaded region has to be a sum of 360° - 270°, or 90°.
now, notice the tickmarks on those angles in the graph above, meaning those two angles are twins, and 90°/2 is 45°, so each of those twins is 45°.
arcYW = 60° + 45°.
