1/12 pieces is shaded. You can divide the hexagon to have 6 equal triangles in the middle. The total triangles would be 12.

A pyramid has a rectangular base with edges of length 10 and 24. The vertex of the pyramid is directly 13 units above the center

laiz [17]

Answer:

Step-by-step explanation:

It is given that A pyramid has a rectangular base with edges of length 10 and 24. The vertex of the pyramid is directly 13 units above the center of the base.. then The total surface area = area of rectangular base + area of 2 isosceles triangles with a base of 24 units + area of 2 isosceles triangles with a base of 10 units.

Area of rectangular base = $24{\times}10=240 sq units$

The slant height of isosceles triangles with a base of 24 units = $(\frac{10}{2})^{2}+(13)^{2})^\frac{1}{2}=(25+169)^{\frac{1}{2}}=13.928units$ .

The area of 2 isosceles triangles with a base of 24 units= $\frac{2{\times}24{\times}13.928}{2}=334.281 sq units$

The slant height of isosceles triangles with a base of 10 units = $((12)^{2}+(13)^{2})^\frac{1}{2}=(144+169)^\frac{1}{2}=17.691 units$

The area of 2 isosceles triangles with a base of 10 units= $\frac{2{\times}10{\times}17.691}{2}=176.918 sq units$

The total surface area of the pyramid = 240 + 334.281 + 176.918 = 591.97 sq units.

If a=-2 and b=-3 and c=2 and x=2.1 and y =3 and z=-4.2 what is the this answer? 4a-| 3b - 8c | -3

MakcuM [25]

Answer:

-36

Step-by-step explanation:

plug in the letters for the numbers, then you get, -8 - 25 - 3. -8 - 25 is -33, then you subtract that to 3. so it should look like, -33 - 3. then simplified even more is -36.

Consider the reaction. Upper n subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper N upper H subscript 3

umka2103 [35]

The equilibrium constant of the reaction is 0.0030.

The equation of the reaction is given as;

N2(g) + 3H2(g) ⇆ 2NH3 (g)

We have the following information at equilibrium;

[NH3] = 0.105 M

[N2] = 1.1 M

[H2] = 1.50 M

Hence, we can calculate the equilibrium constant using the relation;

K = [NH3]^2/ [N2] [H2]^3

Substituting values;

K = [0.105]^2/[ 1.1] [1.50]^3

K =0.011025 /3.7125

K= 0.0030
