How do you solve I = prt?

The fundamentals behind simple interest assume that the same amount of interest is paid every year on a debt, until the debt is paid off. For example, Stephen has a car loan of $30,000 for 5 years with a 3 percent interest rate. Using the formula for simple interest, the equation appears as I = 30,000 x .03 x 5.It is important to remember to designate the percentage as a decimal. In this case, 3 percent is represented as .03. The answer to the above equation is 4,500. This means that Stephen will pay $4,500 in simple interest over the course of 5 years.Another example of the formula for simple..

What is a triangular pyramid?

A triangular pyramid has four faces, four corners (or vertices) and six edges in total. It falls under the designation of a tetrahedron because it has four triangular faces. If all the triangles are identical equilateral triangles, then it is a regular tetrahedron. To calculate the volume of a triangular pyramid, a person would multiply the base area by the height of the pyramid and then divide by 3.

How do you round a number to the place value of an underlined digit?

The first step is to determine whether the digit located directly to the right of the one that is underlined is less than five, or is greater than or equal to five. If that digit is less than five, leave the underlined digit as it is. If the digit is greater than or equal to five, increase the underlined digit by one. In either case, change all numerals to the right of the underlined digit into zeros.\nFor example, if the numeral three was underlined in the number 13,579, the focus would be placed on the digit directly to its right. According to the rules for rounding, because the next digit t..

What is 15 percent as a decimal?

To find this fraction as a decimal, divide the numerator P by the denominator 100. For 15 percent, this is rewritten as 15/100 and expressed as 0.15.\nIn math, students can express decimal numbers by place values. In this positional system, a digit’s position before or after the decimal point determines its place value. The second place value to the right of the decimal point is the hundredth position. Students can also write this decimal in word form as fifteen-hundredths.

How many sides does a pyramid have?

The different types of pyramids are named after the shape of their polygonal base. For example, a pyramid with an octagon shaped base will be an octagonal pyramid. When the shape of the base is not specified, it is typically assumed to be a square. A pyramid with a triangular base is generally referred to as a tetrahedron.\nA pyramid whose apex is located directly above the center of the base are known as right pyramids, while the opposite is called an oblique pyramid. If the base of the pyramid is not a regular polygon, it's called an irregular pyramid; otherwise it's a regular p..

How do you use basic geometry worksheets?

Examining pictures presented on worksheets give students the opportunity to gain hands-on skills by drawing and measuring figures and angles in two-dimensional geometry. Students find it much easier to understand concepts such as length, perimeter, area, angle measurement and transformation when they take pencil to paper.\nStudents should take advantage of the ability to draw on worksheets when studying coordinate geometry. They are no longer required to go through the tedious process of drawing the grid, allowing them to focus on working exercises.\nIn three-dimensional geometry, students sho..

How can you calculate the distance between two cities?

In addition to the air distance, Timeanddate.com provides a map of the shortest path between cities, latitude and longitude of the cities, and local time comparisons.\nDistancetofrom.net provides less overall detail than Timeanddate.com, but allows users to select driving or air distance. Driving distance uses mapped roads to calculate distance, instead of theoretical air distance, and is only available for two cities that are connected by land.

How do you divide rational expressions?

Factor all terms of the expressionsFor example, if you have the expression (x^2 - 5x + 6)/(x^2 + 3x - 2) divided by (x^2 + 3x + 2)/(x + 1), the expressions simplify to (x - 2)(x + 3)/(x - 1)(x - 2) / (x + 1)(x + 2)/(x + 1).Cancel out all like termsAny term divided by itself equals one, so those terms can be canceled out. Doing this leaves the expressions written as (x + 3)/(x - 1) / (x + 2)/1.Multiply the first expression by the reciprocal of the second oneThe reciprocal is the result of the numerator and denominator switching places. Doing this yields the result to be (x + 3)/(x - 1)(x + 2). ..

What is survey of calculus?

The general concepts that people learn in a basic calculus class include limits, indefinite and definite integrals and derivatives. The primary computational techniques students learn include differentiation formulas, integration rules, derivative of standard functions and the fundamental theorem of calculus. The derivative formulas typically include the chain rule, product rule and quotient rule. Students typically take survey of calculus after taking a precalculus class, but not all schools require this prerequisite.

What is a recursive pattern in math?

The numbers in a recursive sequence build off of each other, which is why they must be determined one at a time, and you can't determine the 100th number without first knowing the 99th and numbers before it. A famous example of a recursive sequence is the Fibonacci sequence, where each number is equal to the two before it being added together.
