Answer:
165
Step-by-step explanation: find the area or the field A=r^2
the radius is 290/2=145ft
A=145* 145* 3.14= 66018.5 sqr ft
66018.5 / 400= 165
You would need 16 because 3 × 4 = 12 and you need to do the same to the blue so you would do the equation 4 × 4 = ? which is 16.
An observation study is where nothing changes and you record what is seen. An experimental study you have a control group and a testable group.
The answer would be: .C. The groups in an experiment are chosen at random, but not in an observational study.
You would write the equation like this:
24-10n=64+8n
