Using fractions, it is found that \frac{43}{45} of a wheel still needs to be painted.

  • On the first wheel, 4 of the 9 equal parts have been painted, that is, \frac{4}{9} of the wheel has been painted, hence \frac{5}{9} has not been painted.
  • On the second wheel, 6 of the 10 equal parts have been painted, that is, \frac{6}{10} = \frac{3}{5} of the wheel has been painted, hence \frac{2}{5} has not been painted.

The total fraction that still has to be painted is:

\frac{5}{9} + \frac{2}{5} = \frac{25 + 18}{45} = \frac{43}{45}

\frac{43}{45} of a wheel still needs to be painted.

Write the interval (5,100] as an inequality and using set notation
drek231 [11]

Answer: { x | 5 < x ≤ 100 }  OR  { x ∈ ℝ | 5 < x ≤ 100 }

Step-by-step explanation:

{ x | 5 < x ≤ 100 }

This means:

"The set of all x's, such that x is greater than 5 and less than or equal to 100"

Another acceptable way to write this is

{ x ∈ ℝ | 5 < x ≤ 100 }

"x ∈ ℝ" simply means x is an element of all real numbers

A cutting tool fails due to flank wear while machining. It is observed that the tool life at a cutting speed of 160 m/min is 5 m
Ahat [919]

Answer:

The answer is:

30 minutes.

Step-by-step explanation:

We are given the following information:

at 160 m/min, tool life = 5 min.

at 120 m/min, tool life = 17 min.

This means that as the speed reduced from 160 m/min to 120 m/min, the tool life increased from 5 min. to 17 min, hence the difference between the changes are:

speed = 160 - 120 = 40 m/min

tool life = 17 - 5 = 12 min.

Therefore, it can be concluded that a change of speed of 40 m/min, increases the tool life by 12 min.

40 m/min = 12 min

∴ 1 m/min = 12/40 min.

∴ 100 m/min = 12/40 × 100 = 0.3 × 100 =30 min.
