Finding out this kind of information can be very important to determining the other factors that must be calibrated for a restaurant to succeed. For example, understanding the average check amount can allow restaurants to increase menu items to slightly increase their average revenue from each guest they serve. While these numbers may seem small, during the course of a meal service, or a fiscal year, this small increase in the average check amount can lead to significant increases in overall revenue.Understanding how to carefully increase revenue is important for figuring out the optimal amoun..
Which is greater, the greatest whole number with five digits or the least whole number with six digits?

The set of whole numbers does not include negative numbers. If the question considers the set of integers rather than whole numbers, the lowest six digit integer would be -999,999. Since the greatest integer with five digits would remain 99,999, the answer to the question would change. The set of whole numbers is also known as natural numbers. The similar set of counting numbers is identical to the whole number set, except for the exclusion of zero in the counting numbers set.

However, the notation for integers and their symbolic representation has undergone many changes. The most commonly used symbols for integers are termed Hindu-Arabic numbers and have their origins in ancient India. They were adopted by the Arabic world and eventually replaced the Roman numeral system in Europe. The ability to use 10 symbols in combination to make every possible number makes the Hindu-Arabic system an efficient and easy-to-learn system of notation.

It is possible to calculate the area of a circle by multiplying the square of its radius by pi. In geometry, pi is used to calculate surface area and volumes of cylinders, cones and spheres.\nTrigonometry defines pi as the smallest value for which sine(x) is equal to zero, which integrates the number into wave functions for use in the natural sciences. Physicists include the value of pi in some units, such as Planck units, to eliminate their need for using it repeatedly in calculations. In statistics, distribution formulas, including the normal distribution curve and standard deviations use th..

A trapezoid is a two-dimensional shape with four straight sides and two parallel sides. The angles and lengths of the non-parallel side vary depending on the trapezoid's shape.A handbag is often designed with two trapezoids as the largest sides of the purse. The top and bottom of each side are parallel, but the top edge is usually shorter than the bottom edge.Similarly, a truss bridge often features multiple trapezoids along the sides that connect the base of the bridge to the structure overhead. The steel or aluminum supports form adjacent trapezoids, with the two parallel sides being th..

Prime numbers are whole numbers larger than 1 that can't be divided by any number other than 1 and itself and still result in a whole number. Prime numbers are always odd, because any even number greater than 2 can be divided by 1, 2 and itself. Similarly, any number ending in 5 can't be prime, because it can be divided by 1, 5 and itself.

A regular hexagon has six equal sides with six equal angles of 120 degrees between each side. The formula for the area of a regular hexagon is approximately 2.598 * s * s where s is the length of each side. All other hexagons are irregular. A hexagon is convex if it has no angles that point inwards which also means it has no interior angles greater than 180 degrees. It is concave if there is an interior angle greater than 180 degrees.

To graph a piecewise function, draw each of the function's segments individually, and then erase any part of the segment that falls outside of the limits defined by the inequality. Continue to the next segment until you have drawn all segments. The function is discontinuous wherever a vertical line drawn on the graph passes through more than one point.

Calculate like fractionsThe fractions in addition and subtraction problems must have the same denominators. If the two fractions in a math problem have different denominators, convert the fractions to equivalent fractions that share the same denominator. Add or subtract the numeratorsIn addition problems, add the numerators together to find the numerator of the sum and use the common denominator as the denominator of the sum. For subtraction problems, subtract the second numerator from the first numerator to find the numerator for the difference, and use the common denominator as the denominat..
What is a average savings of a 30 year old?

For the group aged 33 to 44, the median savings amount is $61,000, compared to only $12,000 in the 25-to-32 range. The ideal amount in savings for a 30-year-old is enough to cover expenses for one full year. Thus the right amount varies depending on personal expenses. If a person lives frugally, he potentially saves enough in one to three years to reach this goal. Savings grow with time, since age 30 is quite young in terms of a person's expected work potential.
