Answers
Errors are what makes your measurement invalid and unreliable. There are two types of error which is called the systematic error and the random error. Each error has different sources. Words that were mentioned –invalid and unreliable are very important key aspects to determine that your measure is truly accurate and consistent. Some would recommend using the mean method, doing three trials in measuring and getting their mean, in response to this problem.

Answer: I think the answer is B. measure one side with a ruler, and multiply that number by itself three times.
Explanation:
Answer;
-Measure one side with a ruler, and then cube it, or in other words multiply that number by itself and then by itself again.
Explanation;
-Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance or shape occupies or contains.
- Volume is measured in cubic units, such as the cubic meters, cubic centimeters. The SI units of volume is cubic meters.
A cube has all edges (sides) of the same length. The volume of a cube is found by multiplying the length of any edge by itself twice.

Answer:
The minute hand moves radians.
Step by step explanation:
We know that measure of complete circle is 360 degrees.
In a clock a complete circle means 60 minutes.
The minute hand move from 1:25 to 1:50, it means the minute have cover 25 minutes.
Therefore minute hand moves 150 degree.
Multiply to convert degree into radian.
Therefore the minute hand moves radians.
Calculations are done as follows:
360 ° /60 minutes = 6° per minute
1:25 to 1:50 = 25 minutes
25 minutes x 6° per minute = 150°
150° (π/180) = 5π/6

Malthus’ most famous work, which he published in 1798, was An Essay on the Principle of Population as it affects the Future Improvement of Society. In it, Malthus raised doubts about whether a nation could ever reach a point where laws would no longer be required, and in which everyone lived prosperously and harmoniously. There was, he argued, a built-in agony to human existence, in that the growth of a population will always outrun its ability to feed itself. If every couple raised four children, the population could easily double in twenty-five years, and from then on, it would keep doubling. It would rise not arithmetically—by factors of three, four, five, and so on—but geometrically—by factors of four, eight, and sixteen.
Between 1800 and 2000 the human population increased about six-fold. Has the food supply kept pace? Will there be enough food to support the projected population of 9.2 billion in 2050?If a country’s population did explode this way, Malthus warned that there was no hope that the world’s food supply could keep up. Clearing new land for farming or improving the yields of crops might produce a bigger harvest, but it could only increase arithmetically, not geometrically. Unchecked population growth inevitably brought famine and misery. The only reason that humanity wasn’t already in perpetual famine was because its growth was continually checked by forces such as plagues, infanticide, and simply putting off marriage until middle age. Malthus argued that population growth doomed any efforts to improve the lot of the poor. Extra money would allow the poor to have more children, only hastening the nation’s appointment with famine.A new view of humans
Malthus made his groundbreaking economic arguments by treating human beings in a groundbreaking way. Rather than focusing on the individual, he looked at humans as groups of individuals, all of whom were subject to the same basic laws of behavior. He used the same principles that an ecologist would use studying a population of animals or plants. And indeed, Malthus pointed out that the same forces of fertility and starvation that shaped the human race were also at work on animals and plants. If flies went unchecked in their maggot-making, the world would soon be knee-deep in them. Most flies (and most members of any species you choose) must die without having any offspring. And thus when Darwinadapted Malthus’ ideas to his theory of evolution, it was clear to him that humans must evolve like any other animal.
