When should kids use bar graphs?

Bar graphs work well when plotting data that covers a number of days, weeks or years. This is especially true if the data that is being plotted shows significant changes during the specific time period. The graph has an x-axis that runs horizontally along the bottom of the graph and a y-axis that extends vertically. The x-axis of the graph is typically used to show the time period the graph spans or what is being measured, while the y-axis typically shows the amount of the item that is being measured.

How many tablespoons are in 90 ml?

Tablespoon measurements vary by location or style. Volumes in a US or UK tablespoon vary slightly from the metric measurement. Both US and UK tablespoons are slightly smaller — 90 milliliters equals 6.33 UK tablespoons and 6.08 US tablespoons. These volumes generally apply to liquid measurements.\n\nRecipes may call for level or heaped tablespoons when measuring dry ingredients. A level tablespoon is measured by scraping across the top of the spoon to create a level, full spoon. Sixteen level tablespoons of dry or liquid ingredients equals a cup.

What are non-coplanar points in a plane?

While an individual point has no characteristics, when grouped, points can become collinear, non-collinear, coplanar, or non-coplanar. Any two points have a line that runs through them, and are therefore automatically collinear. To get a non-collinear point, a third point that lies not on the line of the first two is needed. This point is non-collinear with the first two. However, in the same way that any two points are collinear, any three points are automatically coplanar, as it takes three points to define a plane. A fourth point is coplanar with this plane if it also lies in the same plan..

How do solar-powered calculators work?

Solar cells can be found on satellites as well as calculators and can even help to power homes and street lights. The solar cells work by using the photoelectric effect, which is the ability of matter to emit electrons whenever light is shone on the solar cell.Silicone is a semi-conductor and is found within a solar cell. When sunlight is shone on to a solar cell, the minuscule particles called photons hit the silicon atoms in the solar cell and help transfer the energy to loose electrons. These then work to make an imbalance with the silicon atoms as silicon atoms are tightly bound in their ..

Where is a list of Roman numbers from 1 to 100?

The main Roman numerals from one to 100 include I for one, V for five, X for 10, L for 50 and C for 100. With these five Roman numerals, you can form the rest of the Roman numerals from one to 100 by adding and subtracting.\nThe maximum times a Roman numeral can appear in succession is three. I is one, II is two and III is three. To make four, however, you must subtract one from five. When a number is subtracted, it appears to the left of the number from which it is taken. For example, four is IV.\nSix is written as five plus one. When a number is added to another, it appears to the right of i..

What is the sum of the first 100 even numbers?

The calculation for the first 100 numbers is based on a legend of mathematician Carl Friedrich Gauss. According to the story, as a child his teacher asked the class to find the sum of the first 100 numbers to keep them busy. Gauss was able to determine it was 5,050 in a few seconds. He realized that the sum of the first and last number was 101, the second number and the second to last number was 101, and so on, resulting in 50 pairs of 101. He then multiplied 50 by 101 to get 5,050. Since the sum of the first 100 even numbers is double that of the first 100, a person can multiply 5,050 by 2 to..

What is a non-rigid transformation?

A transformation describes any operation that is performed on a shape. Simple transformations, such as moving the object to the left, do not change the size or shape of the object. These types of transformations are known as rigid transformations. Another common type of transformation is a reflection, where the object is flipped to reveal its mirror image, which is another rigid transformation. The final type of rigid transformation is rotation, where the object is rotated in either direction.

How can you find the equation of a parabola?

The equation for a vertical parabola is y=a(x-h)2+k and the equation for a horizontal is x=a(y-k)2+h. The steps to solve the equation remain the same.Step 1: Use the right formula and plug in the numbersDetermine whether the parabola is vertical or horizontal. Substitute the coordinates for the vertex into h and k in the formula. Choose a point on the figure, other than the vertex, and substitute those coordinates into x and y in the formula.Step 2: Solve for the value of aOnce all of the numbers have been plugged in, use simple algebra to solve for the value of a in the formula.Step 3: Rewrit..

What is the cosine of 0?

For a zero-degree angle, the hypotenuse and the adjacent side of the right triangle are the same line, and when a number is divided by itself, the resulting quotient is one. The lengths of the sides of the right triangle used in the function cosine are calculated by using the Pythagorean theorem. The sine of a zero-degree angle has a zero in the numerator and is infinite.

What are some example solutions of linear programming?

In general, a solution to a linear programming problem is the set of variable values for which the problem's linear function is maximized. Problems may have no solution in cases where the problem constraints make this infeasible. A trivially infeasible problem would be one with the constraints "x < 1" and "x > 2," because clearly no value of x could satisfy this.\nAlgorithms that provide general solutions to linear programming problems, such as the simplex method, are detailed on Wikipedia. These are often used to solve problems involving numerous constraints and variables, such as in sol..
