How many diagonal sides does a dodecahedron have?
it has 54 diaganal sides
What is the perimeter of a rhobus when one of its diagonals is 12 cm and has an area of 54 square cm showing work?
Let the other diagonal be x:- If: 0.5*x*12 = 54 Then: x = 54/6 => 9 The rhombus will consist of 4 right angles: base 4.5 cm and height 6 cm Using Pythagoras: hypotenuses = 7.5 cm Therefore perimeter: 4*7.5 = 30 cm
If the larger angle of a rhombus is 126 degrees what is the measure of the smaller angle?
180 - 126 = 54 degrees.
What are two factors of 270 whose sum is 59?
54 x 5 = 270 54 + 5 = 59 The two factors in question are therefore 54 and 5.
What is the area of a rectangle whose length is 9m and whose width is 6m?
Area = 9*6 = 54 square meters
What is the diagonal of 26.8 ft x 54 ft?
60.28 is the length of the diagonal, got through Pythagoras' Theorem.
How many diagonal sides does a dodecahedron have?

Find the area of a rhombus with diagonals of 9 cm and 12 cm?
54
What is the perimeter of a rhobus when one of its diagonals is 12 cm and has an area of 54 square cm showing work?
Let the other diagonal be x:- If: 0.5*x*12 = 54 Then: x = 54/6 => 9 The rhombus will consist of 4 right angles: base 4.5 cm and height 6 cm Using Pythagoras: hypotenuses = 7.5 cm Therefore perimeter: 4*7.5 = 30 cm
Two numbers whose sum is 54 and whose difference is 10?
32 - 22 + 10 32 + 22 = 54
What are the two numbers whose sum is 54 and whose difference is 6?
24 and 30 24 + 30 = 54 and 30 - 24 = 6
How many diagonals in 18-gon?
Using the diagonal formula: 0.5*(182-54) = 135 diagonals
If the larger angle of a rhombus is 126 degrees what is the measure of the smaller angle?
180 - 126 = 54 degrees.
Find the two numbers whose product is 54 and whose sum is 15?
9 and 6
What is the perimeter of a rhombus whose diagonals add up to 21 cm and has an area of 54 square cm showing work?
Let the diagonals be x and y:- If: x+y = 21 then y = 21-x If: 0.5xy = 54 then 0.5x(21-x) = 54 => 21x -x squared -108 = 0 Solving the above quadratic equation: x = 12 or x = 9 The rhombus will then consist of 4 right angle triangles with base 4.5 and height 6 Using Pythagoras' theorem their hypotenuses are 7.5 cm Perimeter: 4*7.5 = 30 cm
What are the 2 smallest numbers whose GCF is 9 and whose LCM is 54?
18 and 9 * * * * * Not so. LCM(9, 18) = 18, not 54. The correct answer is 18, 27.
What is the supplement of an angle whose measure is 126 degrees?
54 degrees 180 - 126 = 54
