### How many linear feet is 18 sq.ft.

You get square feet by multiplying linear feet with another linear feet. 18 sq.ft = 3 lin ft x 6 lin ft or 2 lin ft x 9 lin feet or 4,5 lin ft x 4lin feet.
Sq ft is used to quantify surface area where linear feet quantify distance but lin ft x lin ft gives you square ft (surface area)

### What is the differance between a class 2 safety vest & a class 3 safety vest & is there a class 1

Class 1 safety vests are for workers in low impact areas, where traffic flow does not exceed 25 mph and where personnel are working a good distance away from it. Parking service attendants, delivery vehicle drivers, and sidewalk or roadside maintenance workers are examples of jobs who would qualify for a class 1 safety vest. These vests should have a mandatory minimum of 155 square inches of reflective tape. Dimensions of the reflective tape can be either 6.46 linear feet of 2 inch tape or 9.39 linear feet of 1 3/8 inch tape. The reflective stripes should be around the middle in a 360? stripe and above each shoulder. Vests should be either a safety yellow or safety orange color.
Workers who are involved in jobs where there is heavier traffic are required to wear a Class 2 vest. Jobs that require workers to work in areas where there is poor visibility due to weather will also need a more reflective Class 2 safety vest. Class 2 vests will have a minimum of 201 square inches of reflective tape that is 2 inches in diameter. Dimensions of the reflective tape can be 8.373 linear feet of 2-inch tape or 12.2 linear feet of 1 3/3 inch tape. Examples of jobs that require Class 2 vests are airport baggage handlers and ground crew, forestry workers, high-volume parking or toll-gate personnel and law enforcement personnel. Reflective stripes will be over the shoulders and round the middle in either one or two 360? horizontal stripes.
Jobs that require workers to be the most visible are ones that put personnel in close contact with heavy traffic. High risk jobs include accident site investigators, emergency responders, railway workers, utility workers, and survey and flagging crews. These workers will often be close to traffic exceeding 50 miles an hour, so it is important for them to be as visible as possible. Class 3 safety vests and garments must have a minimum of 310 square inches of reflective tape that is 12.92 linear feet and 2-inches thick. Class 3 garments also provide more coverage to the arms and legs than do class 1 and class 2 safety vests.

### How do i calculate 600 square feet of 5/4" x 6" decking into linear feet

2 Linear feet of 6" Material would make 1 Sq Ft.
so 1200 linear feet should do it.

### How many feet is 350 linear feet?

Linear feet are a measure of length (no different from feet); square feet measure area. You cannot simply convert between measures of different kinds of quantities;the connection between them will be specific to a particular problem.A practical example in which this question can arise is in buying countertops for a kitchen. Some materials are sold by the square foot; others (basically those that are extruded, so they come in standard widths) are sold by the linear foot. In order to compare the two, you need to compute the area and wall length for the countertop you want.You can't convert between the two. All you have to do is to make the appropriate measurements so you can calculate the price of each item.The terms used in the lumber industry are a bit confusing.There are two terms that I think you might be mixing up.A LINEAR FOOT is simply the length of a board. If you want to know the area or volume of the board,you need additional information. For instance, 6 linear feet of 1-by-12 has an area of 6 square feet (12 inches = 1 foot, times 6 feet), and it's 1 inch thick, so the volume is 1/2 cubic foot (6 square feet times 1/12 foot). But 6 linear feet of a 1-by-6 board would have half the area and half the volume.A BOARD FOOT is equivalent to one square foot of a 1-inch-thick board. In other words, it is a square-foot-inch (ft^2-in), or 1/12 cubic foot.Linear feet are used for the pricing of a single size such as two-by-fours. Board feet are used for larger lumber that you are more likely to want to compare directly with different size boards .To sum up, neither a linear foot nor a board foot can be converted directly to square feet. A linear foot is a linear (length) measure, and a board foot is a volume measure. You need to know your particular board to do anything more, such as find the area.an example with an" L" shaped countertop will betwo rectangles are 24 by 80 inches and 24 by 36 inches. Thus the area is: 24 * 80 + 24 * 36 = 24 * (80 + 36) = 24 * 116= 2784 sq. in.To get it in square feet, divide by 144:
2784 / 144 = 19.33 sq. ft.The linear measure of this countertop would be 60 + 80 = 140 inches = 140/12 feet = 11.67 feet

### Edit Casio FX - 9860G SD have complex equations??

Thhe Casio FX-9860G SD can solve a polynomial equation of degree 2 or 3 with REAL coefficients. If the complex MODE is set to REAL it will find the real roots. If the complex mode is set to a+ib, it will find the real and complex roots.

Apparently it will take coefficients that are real, and will give a Ma Error if any coefficient is complex.

The calculator CANNOT solve equations with complex coefficient. YOU can however convert the system of linear equations with ccomplex coefficients ( of the type you show) as a system of 4 linear equations in 4 unknowns; Split x into a real and an imaginary part, split y into a real and an imaginary part. Substitute Real(x)+iIm(x) for variable x in the equations; substitute Real(y)+iIm(y) for y in the two equations; do the algebra. In each of the original equations split the Real and imaginary parts. You should be able to derive 4 linear equations in unknowns Real(x), Im(x), Real(y), and Im(y).
Use the linear equation solver to obtain the solutions. Recompose x=Real(x)+iIm(x), and y=Real(y)+iIm(y)

Alternatively, after you create the system of 4 linear equations you can use the matrix utility to find Real(x), Im(x), Real(y) and Im(y) and recompose the x and y.

### Am trying to calculate corelation on a Casio fx-9750GII,

Use arrows to highlight STAT icon and press EXE.
Enter your data in two lists (x-values in L1, Y-values in L2)
Press F2 to activate the CALC Tab at the bottom of screen.

This is what you see.

Press F3 to activate the REGression tab.
This is what you will see: the TABs at the bottom of screen.
Each tab corresponds to a regression model: X-linear, X2 quadratic, etc.

If you press F3:X^2, you get the following

You see the parameters of the regression equation, the coefficient of determination r^2, and the Mean Square error. No correlation coefficient is defined for this regression model.
For other models like linear, logarithmic, power and exponential regressions, the correlation coefficient is defined and is thus displayed with the regression equation. It is the r-value.
