Answer:
Independent Variable- size of aquariums
Dependent variable - number of surviving fish
Controls: nil
Step-by-step explanation:
In every experiment, the independent variable is manipulated and its effect on the dependent variable is observed as certain factors are kept constant.
In this study, the independent variable is the size of the aquariums. As this factor is manipulated, the number of surviving fish (dependent variable) changed accordingly. There was no mention of a control group in the experiment.
However, temperature, amount of food and type of food were held constant for all the experimental groups.
Answer:
The correct ans is...
3 x square + 5 x - 5
Step-by-step explanation:
U can only subtract or add if u hv the same variable..
here -2x and 7x have the same variable...
so -2x + 7x = 5x
Therefore the ans is....
3 x square + 5 x - 5
Hope this helps....
Have a GOOD DAY !!!!
Pls mark my ans as brainliest
If u mark my ans as brainliest u will get 3 extra points
Sry to say....
U really need to read ur Math TBK
Answer:
172.70 sq. ft.
Step-by-step explanation:
The surface area of a circular cone is
r = radius of base l = slant height
r = 4.4 and l = 8.1
SA = 3.14(19.36) + 111.9096
= 60.7904 + 111.9096
= 172.70 sq. ft.
