What are all the factors of 42?

The definition of a factor in mathematics is one of two or more numbers that when multiplied together produce a specific product. The way to calculate the factors of 42 is to start off with the first two factors of every number, which are one and the number itself.\nThe next step is to progressively use multiplication to see if a number is divisible by 42. For instance, two is divisible by 42 and the result is 21, which means that both two and 21 are factors of 42. The same can be said for the number three, which is divisible by 42 and the result is 14, making three and 14 factors of 42.\nAs ..

How many sides does an octagon have?

In Christianity, the baptismal fonts are often octagonal in shape. This shape is to represent the eight days between the arrival of Christ in Jerusalem and His resurrection and rebirth eight days later. In Islam, an octagon is often placed in the center of a garden. The shape represents a transition between a square, which represents the earth, and a circle, which represents heaven.

How do you measure diameter?

If the area of a circle is known, the diameter is the square root of 4A/Pi, where A is the area of the circle and Pi is approximately 3.142. The diameter of the circle is the length of the line through the center of the circle that touches two of the points on its edge The center of the circle is the midpoint of the diameter. A diameter may also be referred to as a chord, which is any line that joins two points on a circle. The diameter is the longest chord on any circle.

How many pints in a unit of blood?

Brookhaven National Laboratory explains that within one unit of blood there are several components, including red blood cells, white blood cells, plasma, platelets and cryoprecipitate. Each component of blood can be stored for differing amounts of time, with plasma lasting the longest. While red blood cells carry oxygen to the body's organs and tissue, white blood cells are the body's primary defense against infection. Platelets help blood to clot. Each ill person requires differing amounts of the components that make up blood depending on his condition.

What is the equation for height, width and length?

There are several different formulas to determine the volume of different types of solid objects. For example, the volume of a cylinder is found by the equation V = pi * r^2 * h, where r is the radius of the end of the cylinder and h is the height of the cylinder. The volume of a sphere is V = (4 / 3) * pi * r^3, where r is the radius of the sphere.

What is the antiderivative formula?

1. The derivative of a constant is 0. A constant is any number that exists on its own without a variable. Therefore 3 is a constant, but 3x is not. For example, the antiderivative of f(x) = x^2dx is F(X) = X^3/3 + C. It is necessary to add the C because there's no way of knowing exactly what number is in the place of the C, but it is known that it's possible for a number to exist there.\n2. The Power Rule: Used when finding the antiderivative of a function whose variable has an exponent. So for x^n, as long as n is not equal to -1, the antiderivative is x^(n+1)/ (n + 1)+ C. For examp..

How do you get a metric converter online for free?

Students can use these metric converters by simply clicking on the type of conversion required, such as centimeters to meters, and then entering the required measurement. For example, typing in 1500 for centimeters should give an answer of 15 meters. This site provides an extensive listing of commonly used metric conversions. There are also other metric conversion tools, such as for area and volume. The area conversion tool can convert from areas that include square meters to square centimeters, square inches, square kilometers and more.The World Wide Metric is a handy converter tool, which co..

How do you calculate percentile?

Arrange the data setArrange all of the numbers in the data set into sequence from lowest to highest. This makes it easier to determine precisely which number in the set is at a specific percentile point.Calculate the percentile pointCount the number of items in the data set, and multiply the result by the percentile desired. For example, the 90th percentile of a data set of 100 numbers would require multiplying 0.90 by 100. The result is the position of the number in the data set that is in the 90th percentile place. Anything below that number is a data set containing the lowest 90 percent of ..

What are some arithmetic practice problems?

Lower elementary school-aged children can be taught math and reasoning skills by using simple arithmetic word problems. An example of a practice arithmetic word problem is a question such as "If Sally had 10 apples and she gave two of them to Bob and six of them to Ted, how many apples did she have left?" Another type of arithmetic practice problem for this age group is putting numbers on a grid in a certain pattern, with a few spaces left open. The child will then need to figure out what the missing numbers are and put the correct numbers in the blank spaces.\nChildren in higher grades will w..

What does Pi equal?

Pi, by definition, is the ratio of a circle’s circumference to its diameter (Pi = C/d). This constant is used to solve the area of a circle, with the formula “Pi r squared” or “the product of Pi and the square of the length of the radius.” The rounded-off version of Pi is accepted for general computations. Here’s Pi up to 20 decimal digits: 3.14159265358979323846.
