Answer:

D) 5

Step-by-step explanation:

This is the median of the trapezoid.  It is the line segment that connects the midpoints of the non-parallel sides of the trapezoid.

The length of the median of a trapezoid is equal to 1/2 the sum of the bases; this makes ours

1/2(3.3+6.7) = 1/2(10) = 5

Answer:   D. 5

Step-by-step explanation:

In the given figure , we have give a trapezioid ABCD with parallel sides BC= 3.3 units and AD= 6.7 units.

Also, E and F appears as the mid points of non parallel sides AB and CD and parallel to the bases BC and AD.

⇒ EF would be the median of trapezioid ABCD.

Also, we know that , the length of the median of a trapezoid equals to one-half the sum of the lengths of the two bases.

i.e. length of EF = \dfrac{1}{2}(AD+BC)

i.e. length of EF = \dfrac{1}{2}(6.7+3.3)

i.e. length of EF = \dfrac{1}{2}(10)

i.e. length of EF = 5 units.

Suppose you are given a cube made of magnesium (mg) metal of edge length 2.15 cm. (a) calculate the number of mg atoms in the cu
SVETLANKA909090 [29]

solution:

a) To calculate the volume of cube of edge 1.0cm

Volume= (edge)³

=(100cm) ³

= 1cm³

To find the mass of MG atoms  

Density = mass/volume

Mass of mg = 1.74g/cm³ x 1cm³

       = 1.74g

To find the number of mg atoms,

Molar mass of mg = 24.31g

24.31g mg contain 6.022 x 10²³ atoms of mg  

1.74g mg contain = 6.022 x 10²³mg atoms/24.31g mg x 1.74g mg

    = 0.4310 x 10²³mg atoms

    = 4.31 x 10²² mg atoms

B) to find the volume occupied by mg atoms  

    Total volume of cube = 1 cm³

    Volume occupied by mg atoms  

  = 74% of 1cm³

=74/100 x 1cm³= 0.74cm³

To find the volume of 1 mg atom  

4.31 x 10²² mg atoms occupy 0.74 cm³

1 atom will occupy 0.74cm³

1 atom will occupy = 0.74cm³/4.31 x 10²²mg atoms x 1mg atom

volume of 1 mg atom = 0.1716 x 10⁻²²cm²

Volume of 1 mg atom = 4/3 π³ in the form of sphere.

4/3πr³ = 0.1716 x 10⁻²²cm³

R³ = 0.1716 x 10⁻²²cm³x 4/3 x 7/22

R³ = 0.04095 x 10⁻²²cm³

R = 0.1599 x 10⁻⁷cm

1 = 10⁻¹⁰cm

 = 0.1599 x 10⁻⁷cm

 = 1pm/1 x 10⁻¹⁰cm  x 0.1599 x 10-7cm

= 1.599 x 10² pm  

R= 1.6 x 10²pm
