Answer:
4
Step-by-step explanation:
In this experiment, there will be a total of four experimental units. This is because there will be two options either baking soda or bleach and each one of these will have two experimental units when combined with either cold or warm water. Therefore, we can create the following units as such...
Baking Soda + Cold Water
Baking Soda + Warm Water
Bleach + Cold Water
Bleach + Warm Water
These would be the 4 total experimental units in this experiment.

Answer:
(3 S.F)
Step-by-step explanation:
Diameter of circle (D) = one side of the equilateral ∆
Circumference of the circle = πD = 48 cm
Thus:
πD = 48
Divide both sides by π
D = = 15.3 cm (approximated to nearest tenth)
Since all sides an equilateral ∆ are equal, therefore, and the diameter, D, of the circle given is the same as the length of one side of the ∆, therefore, all sides of the equilateral triangle would be 15.3 cm.
Recall that the area of a triangle can be found if we know lengths of the two sides of the ∆ and the measure of the included angle between both sides.
Since an equilateral ∆ has equal angles, each measuring 60°, then we already have all the information needed to calculate the area of the ∆.
Thus:
Length of the two sides = 15.3 cm and
15.3 cm
Included angle = 60°
Use the following formula:
Where,
a = 15.3 cm
b = 15.3 cm
C = 60°
Plug the values into the formula to find the area.
