The width of this rectangle is measured as 19.4mm correct to 1 decimal place.
Afina-wow [57]

Answer:

reducing 9.35  to  19.44  is rounded to 19.4  

Step-by-step explanation:

9.35  to  19.44  is rounded to 19.4  

19.35  = 19.4

19.36  = 19.4

19.37 = 19.4

19.38 = 19.4

19.39 = 19.4

19.40 = 19.4

19.41  = 19.4

19.42 = 19.4

19.43 = 19.4

19.44 = 19.4

Hence Lower bound of   of the rectangle  = 19.35 mm

Complete the statements about these similar pyramids.
Goryan [66]
  • The ratio of the heights of the pyramid given at the end of the answer is of: 1:3.
  • The ratio of the surface areas of the pyramid given at the end of the answer is of: 1:9.
  • The ratio of the volumes of the pyramid given at the end of the answer is of: 1:27.

<h3>How to obtain the ratios?</h3>

The first step in obtaining the ratios is finding the ratio of the heights, which is given as follows:

5:15 = 1:3.

The heights are measured in units, while the surface area is measured in units squared, hence the ratio is squared, as follows:

(1:3)² = 1:9.

The volume is measured in cubic units, hence the ratio is cubed, as follows:

(1:3)³ = 1:27.

<h3>Missing Information</h3>

The pyramid is given at the end of the answer.

For different dimensions, the procedure of taking the ratio of the heights, then the surface area is squared and the volume is cubed remains.
