If a cable is 42 ft long and is divided into lengths of a ratio of 3 to 4 what are the two lengths into which the cable is divded?
If a cable is 42 ft long and is divided into lengths of a ratio of 3 to 4 what are the two lengths into which the cable is divided?
Ratio 3:4
= 3 parts of 42: 4 parts of 42 Total number of parts = 7
= (42/7)x3 : (42/7)x4
= 18ft : 24ft
Soln: the two lengths of cable are 18ft and 24ft.

The ratio of the lengths of corresponding parts in two similar solids is 4 1 what is the ratio of their surface areas-?
The ratio of their surface areas is the square of the ratio of the lengths. Since the ratio of the lengths is 4-1, then the ratio of the surface areas is 4^2-1^2 or 16-1.
What is the ratio for the volumes of two similar spheres given that the ratio of their radii is 3 4?
ratio of volumes is the cube of the ratio of lengths radii (lengths) in ratio 3 : 4 → volume in ratio 3³ : 4³ = 27 : 64
If two cylinders are similar and the ratio between the altitude lengths is 23 what is the ratio of their volumes?
The ratio of their volumes is 23^3 = 12167.
What is the ratio for the volumes of two similar pyramids given that the ratio of their edge lengths is 5 to 7?
The ratio is 57 cubed. This answer does not depend on the fact that you are comparing two similar pyramids; it works the same for two cubes, two spheres, etc. - in general, for any two similar 3D objects.
The ratio of the corresponding edge lengths of two similar is 3 7 what is the ratio of their volumes?
27:343
What happens to the area of a pentagon if the sides are doubled?
The ratio of areas is the square of the ratio of lengths. Ratio lengths = 1 : 2 → ratio areas = 1² : 2² = 1 : 4 → if the lengths are doubled, the areas of quadrupled (multiplied by 4).
The ratio of the lengths of corresponding parts in two similar solids is 4 1 what is the ratio of their surface areas-?
The ratio of their surface areas is the square of the ratio of the lengths. Since the ratio of the lengths is 4-1, then the ratio of the surface areas is 4^2-1^2 or 16-1.
What is the ratio of 5474 divded by 1850?
It is 5474/1850 = 2737/925 which cannot be simplified further.
If two cylinders are similar and the ratio between the lengths of their edges is 2 5 what is the ratio of their volumes?
As volume is length x length x length, cube the ratio of the lengths, thus: Ratio of lengths = 2 : 5 ⇒ Ratio of volumes = 23 : 53 = 8 : 125
The two solids below are similar and the ratio between the lengths of their edges is 35. What is the ratio of their surface areas?
If the lengths are in the ratio 3:5, then the surface areas are in the ratio 9:25.
What is the ratio of the corresponding edge lengths of two similar solids is 49 what is the ratio of their volumes?
If the ratio of side lengths is 49 (that is 49 to 1) then the ratio of their volumes is 493 to 1, which is 117,649 to 1.
What is the ratio for the volumes of two similar spheres given that the ratio of their radii is 3 4?
ratio of volumes is the cube of the ratio of lengths radii (lengths) in ratio 3 : 4 → volume in ratio 3³ : 4³ = 27 : 64
The ratio of the lengths of corresponding parts in two similar solids is 41 What is the ratio of their surface areas?
Area = length x length Therefore the ratio of areas of two similar objects is the square of the ratio of lengths. Lengths - 1 : 41 Areas - 12 : 412 = 1 : 1681
