How do you check to see if a roof is square?
The frame should be checked prior to the rafters going on. Once the roof is on , you will just have to deal with what you have. The horse is out of the barn...
A new figure made after a transformation is called?
In mathematical terms, the figure that is made after a transformation is what is known as an image. Prior to the chance, the figure is called the pre-image. Changing into an image can take place after four types of mathematical transformations: translation, reflection, rotation and dilation.
What is the average labor cost for porcelain tile installation?
In southeastern PA, the cost of installing porcelain tile should begin around $4.00 per square foot. This price represents a basic installation of simple 12 X 12 tile over a smooth, flat concrete surface. Upgrades would include a large format tile (larger than 12 X 12), a patterned installation, or any special considerations such as expansion joints and transitions. If the tile is being installed over a plywood sub-floor, an approved cement or fiber-cement based subfloor must be installed prior to the installation of the tile. This labor charge usually runs about $2.00 per square foot (materials are additional). Grout installation is included in the tile installation labor charge. Installation of tile on walls in showers and kitchens is usually higher and usually requires a site visit prior to pricing.
Who popularized the Pi symbol?
The symbol for pi (π) has been used in mathematics for centuries to represent the ratio of a circle's circumference to its diameter. The use of the symbol π to represent this ratio was popularized by the Welsh mathematician William Jones in 1706. Jones introduced the symbol in his book "Synopsis Palmariorum Matheseos," where he used π as an abbreviation for "periphery." Over time, the symbol became widely adopted in mathematical literature and is now universally recognized as representing the mathematical constant pi.
Does 1 kg of wood of sawdust have a greater surface area than one large piece of wood with a mass of 1 kg?
Surface area increases when fractionating into smaller particles. The large piece of wood will have a smaller surface area than the same mass of wood in sawdust.Example of surface area:Soils: From 1 - 800 m2 g-1, dependent to clay content.Organic matter: From 20 - 600 m2 g-1.BET is a standard method (developed in 1938) for determination of surface area together with EG (ethylene glycol) method. Both require specific particle fractioning prior to analysis and have to be carried out in a Laboratory.However, a quick an accurate DIY method is to weigh a small amount of sawdust (ideally 1g) using a kitchen scale and count the amount of particles in 1g. Then using a ruler measure the area of five particles (replicates) and calculate the average particle area by multiplying by 2 (both sides of the particle). Then multiply this area by the number of particles contained in 1g (or whichever mass previously weighed) and then extrapolate to 1 kilo.Do the same with the large piece of wood for comparison.Good luckP.A.D.V.
