deff fn [24]

Answer:

The sign would be 784 ft. long.

Step-by-step explanation:

The sign would be painted across the total perimeter of the building.

- the distance across the front of the store is 294 feet

- the distance from the front to the back is one third of this distance = (1/3) × 294 = 98 ft.

The perimeter of a rectangular = 2(L + B)

L = length of the building = 294 ft.

B = Breadth of the building = 98 ft.

Perimeter of the chocolate factory that the Sign would be painted across = 2(294 + 98) = 784 ft.

Hope this Helps!!!

Joe measured the diameter of a tennis ball correct to the nearest millimetre. The upper bound of his measurement was 6.75 centim
Mandarinka [93]

The lower bound of the measurement is 65.5 millimetres.

A centimetre equals 10 millimetres, a measure is expressed by the <em>measured</em> magnitude plus uncertainty, the latter one represents the grade of precision of the measure instrument. That is to say:

y = x + \epsilon (1)

Where:

  • x - Measured magnitude, in millimeters.
  • y - Possible magnitude, in millimeters.
  • \epsilon - Uncertainty, in millimeters.

If we know that y = 67.5\,mm and \epsilon = 1\,mm, then the lower bound of the measurement is:

y = 67.5\,mm - 2\cdot (1\,mm)

y = 65.5\,mm

The lower bound of the measurement is 65.5 millimeters.
