Density=mass/volume
given mass=120g and volume=200cm3
density=

or abot 0.6
the density is
The ratio of low-top to the total number of shoes is 4:15
Ratio A is 26/169, and when simplified it is 2/13.
Ratio B is 36/78, and when simplified it is 6/13.
Hope this helped!
Sorry but I don’t think you can simplify a repeating number all you can do is round it to 2.83:)
Given:
Length of the ladder = 20 ft
Distance between base of the ladder and wall = 4 ft
To find:
The angle measure of the ladder to the ground to the nearest degree.
Solution:
Ladder is the hypotenuse of a right triangle. Here, we have,
Hypotenuse = 20 ft
Base = 4 ft
In a right angle triangle,



Taking cos inverse on both sides, we get



Therefore, the correct option is A.
