Answer:
<h2>50, percentage decreased by 14% (percent) of its value = 43</h2>
Answer:
2% profit
Step-by-step explanation:
x = price
50kg = 50x
30kg => 35x
20kg => 16x
35x + 16x = 51x
51x - 50x = x
50x .............. 100%
x ...................... p%
p = 1×100/50 = 100/50 = 2%
Answer:
8:27
Step-by-step explanation:
1 way to do it is...
The volume of a sphere is 4/3*pi*r^3. Plugging in 2 and 3 in for the radii you get the volumes are about 33.51 and 113.1, which is an 8:27 ratio.
Another way to do it is...
The ratio of the radii is 2:3 and a radius is 1-dimensional. The volume, however is 3-dimensional. To get from 1-D to 3-D, you have to cube the numbers. 2^3 is 8 and 3^3 is 27, so the ration is 8:27.
