How to calculate percentage of an amount? Use the percentage formula:
Tom saw a bike for £150 with an additional 10% discount off how much did he get of the original price?
Convert the problem to the equation using the percentage formula: P% * X = Y ÷ 100 (percentage times X equal Y÷ 100) P = 10% and X = 150 so the equation is 10% x 150 = 1500 ÷ 100= 15 Therefore Y =15 therefore Tom got £15 off the original price Solution: Y= is 10% of 150 Equation: Y = P% * X Y = 10% * 150 =1500 Converting percent to decimal: Y = 1500 ÷ 100 = 15 Y = 15
Method Two find the 40% of 96 You divide your percentage by 100. So, 40% would be 40 divided by 100 . Once you have the decimal version of your percentage, simply multiply it by the given number. Pecenatge% ÷ by 100 = answers X Amount 40-100 = 0.4 x 96 = 38.40 40% of 96 = 38.40
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. There are six common triangles and sometimes children get confuse about how to differentiate these six triangles. Please read the images below and take how quiz to assess your knowledge
Formulas that are associated with triangles
Area: ½ × base × height
Perimeter: sum of side lengths of the triangle
Number of vertices: 3
Number of edges: 3
Sum of interior angles: 180
A circle is a round, regular, two-dimensional shape, shaped like the letter o. The centre of a circle is the point in the very middle. Radius: The distance from the center of the circle to its outer rim.
Chord: A line segment whose endpoints are on a circle.
Diameter: A chord that passes through the center of the circle. The length of a diameter is two times the length of a radius.
Secant: A line that intersects a circle in two points.
Tangent: A line that intersects a circle in exactly one point.
Point of Tangency: The point where a tangent line touches the circle
All points on the edge of the circle are at the same distance from the centre. Take a look at the circle below, each parts are named by a letter or combination of letters. Use the combinations of letters to identify the part of the circle by taking our quiz below.
