The soil for house plants consists of 12% water. If someone wants to plant flowers
that need 28% water in the soil, how many liters of water they need to add to 5 kg of
soil?
The liters of water they need to add to 5 kg of soil is equal to
3.66 dl water.
We have given,
Anna bought soil that contains 12% of water.
She wants to plant a flower that needs 18% of water.
We have to determine, how much water does she need to pour in 5 kg of soil to plant the flower
Now, anna bought soil that contains 12% of water
5 kg of soil
Water = (12/100)2 = 0.6 kg
Let Water poured = W kg or liter
What is the total water?The addition of the amount of all water given in the question.
Therefore we get,
Total Water = 0.6 + W kg
Total Soil = 5 + W kg
18% of water
(18/100)(5 + W) = 0.6 + W
90 + 18W = 60 + 100W
30 = 82W
W = 30/82
W = 0.366 kg or 0.366 litre
or 3.66 dl
The liters of water they need to add to 5 kg of
soil is equal to 3.66 dl water.

x^2 = 100
x = sqrt(100)
x = 10 ft
Answer:
10 ft

use the pythagorean theorem:
a^2+b^2=c^2
6^2+8^2=c^2
36+64=c^2
100=c^2
square root of 100 = 10

Enter the diameter of a circle. The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle, or any two points on the circle as long as they are exactly 180 degrees apart
This is the total length of the edge around the circle with the specified diameter, if it was straightened out.
