Formula:
V = 1/3 * b^2 * h
Plug in what we know:
V = 1/3 * 7^2 * 16
Simplify the exponent:
V = 1/3 * 49 * 16
Multiply all 3 numbers together:
V = 261.3cm^3
Answer:
B) Experiment: you imposed a treatment (new fertilizer on some plants, old on others) to determine its effect.
Step-by-step explanation:
In this situation, the fertilizer developer wants to evaluate a hypothesis, not just observe, by subjecting plants to two different treatments (new and old fertilizer) in order to determine which treatment provides a more desirable effect (more plant growth).
This process configures an experiment.
The answer is alternative B)
Only D is correct, it intersects at 90 degrees so it cant be obtuse or acute and never intersecting would be parallel lines <span />
<span><u><em>The correct answer is:</em></u>
2.
<u><em>Explanation</em></u><span><u><em>:</em></u>
20 hundreds =20*100=2000;
this is two thousand, so it is made of 2 thousands.</span></span>
