What is the square root of 2025?

The number 2,025 ends with the number 5, so it can definitely be divided by 5, which makes 405. Dividing the 405 by 5 again results in 81, which is 9 squared. As the number has been divided by 5 twice, this shows that it can be divided by 25, which has a square root of 5. Because the results give two perfect squares, 25 and 81, one can simply multiply the square roots of 5 and 9, respectively. Five multiplied by 9 is 45.

Math games on TopMarks.co.uk are designed for students who are beginning to learn multiplication facts. These online games include "Hit the Button," which quizzes students on times tables. Another game teaches the 4 times table by asking students to pop multiplication fact bubbles in an undersea scene. A simple grid game encourages students to fill in multiplication facts; students may compete in a timed game or go at their own pace. A matching game lists multiplication facts for tables 1 through 9; students can follow along with the material as it is presented to them.\nMultiplication.com use..
What is 12.5 as a fraction?

To convert 12.5 to a fraction, consider the decimal portion of the number, .5. Since .5 is in the tenth spot of the decimal, it may be read as five-tenths, or 5/10. To reduce it to lowest terms, find the lowest common denominator, 5, and divide each by that number to get 1/2, or one-half. Thus, the number is now 12 1/2. To convert this mixed number into an entirely rational fraction, multiply the whole number, 12, by the denominator, 2, to get 24, then add the numerator, to end up with 25. This is the new numerator, so the rational number is 25/2. To check the work, divide 25 by 2 on a calcula..

Density-dependent factors have the greatest effect in large, dense populations. Where an area is overcrowded, for example, competition for food, water and sunlight is much more severe. Competition between species may lead to evolutionary changes over time.\nThe predator-prey relationship, predation, is one of the most well-known forms of population control.\nLimiting factors are those factors that cause the population growth to stop or decrease.

Find the whole numberDivide the numerator by the denominator to get the quotient, otherwise known as the whole number.Find the fractionExpress the remainder produced by the division as the numerator of a new fraction that has the same denominator as the old fraction.Write the mixed numberWrite the whole number as the coefficient of the fraction. For instance, if the improper fraction is 19/3, the mixed number is 6 1/3.

Reflection can also be called a flip. In a reflection, one object is transformed into a mirror image of itself; this is one of the three main methods of isometry, which is the act of moving something without changing its size or shape (within a single plane).\nIn isometry, you can rotate an object, which just means turning it; you can translate it, which is just a translation of the object's location (moving it without turning); and you can reflect it, which is just like looking at an object in the mirror. This flips the object over, creating a reverse image of the object the exact distan..

Find the length and the widthMeasure the length and the width of the square or rectangle. You only need to measure one side for a square, since all of the sides are equal in length.Calculate the areaTo calculate the area, multiply the length by the width. Add up to find perimeterTo find the perimeter, find the total measurement of the shape's outline. Find the sum of the lengths of all four sides of the square or rectangle. Alternatively, you can use this formula as a shortcut: (length x 2) + (width x 2).
How many vertices does a sphere have?

Spheres have some oddities that make them different from all other three-dimensional objects that students learn about in geometry. It always has perfect symmetry, by definition, and it is not a polyhedron (because it has no faces). On any sphere, all of the surface points are precisely the same distance from the middle.\nAmong all of the three-dimensional shapes, spheres can contain the most volume for a set surface area. This means that when comparing a pyramid and sphere with identical surface area values, for example, the sphere has more volume. To see proof of this in action, an individua..
What is frictional force?

Frictional forces are affected by the texture of the surfaces and the amount of force pushing them together. The angle and position of the objects affects the amount of frictional force. If an object is sitting flat against an object, then the frictional force is equal to the object's weight. If the object is pushed against the surface, the frictional force is increased and becomes greater than the object's weight. Objects pulled away from the surface and those at an incline with the surface have less frictional resistance.

The inverse of a number corresponds to the type of number it is reciprocating; all real numbers yield real reciprocals, rational numbers yield rational reciprocals and complex numbers yield complex reciprocals. In linear algebra, when matrix A is multiplied by matrix B to produce the identity matrix, A is said to be nonsingular or invertible with its inverse being B.
