What are the rules for simplifying polynomials?
top times top, bottom times bottom
How do you you cross multiply?
if youre dealing with fractions then you multiply top by top and bottom by bottom then simplify
How do you remove the negative from the denominator?
Multiply top and bottom by -1.
What shape has 6 flat faces 2 are squares 4 are rectangles 12 straight edges and 8 corners?
A square box - with top and bottom both square. (or a box with square ends)The top and bottom make two squares, the four other sides are flat and rectangular. There are eight corners - four around the top and four around the bottom. There are twelve edges, four around the top, four around the bottom, and four joining the top and bottom.A rectangular box is also called a rectangular parallelepiped.
Why does it make sense that slopes of perpendicular lines have opposite signs?
Because if one of the pair of lines is going from bottom left to top right, the other is going from bottom right to top left.
When measuring you do the measurement from the bottom of the meniscus?
You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.
What part of the meniscus do you measure from?
You measure from the bottom of the meniscus, at eye level.
When you are measuring the volume of water in a graduated cylinder do you look at the top of the meniscus or the bottom of the meniscus?
You should always measure the volume of liquid in a graduated cylinder at the bottom of the meniscus, where the curve of the liquid meets the cylinder's surface. This ensures an accurate reading of the volume contained in the cylinder.
When you measure liquid volume you measure at the bottom the?
Meniscus
What is the bottom of the bubble called that you use to measure volume?
meniscus
How do you read meniscus on a graduated cylinder?
All liquids have a surface tension. This tension creates a meniscus or curve on the surface, most noticeable in small diameter tubes or cylinders. The meniscus of water curves up the sides of the cylinder, while heavy liquids like mercury curves down the cylinder. You should always measure light liquids at the bottom of the meniscus and heavy liquids at the top of the meniscus.
How is a meniscus used in measuring?
A meniscus is used in measuring liquids in a graduated cylinder. The bottom of the meniscus is the point that should be read to get an accurate measurement. The curve of the meniscus is caused by surface tension.
Do you read at the top or bottom of a meniscus when drawing med up in a syringe from a vial?
Top
What is the bottom of the meniscus called?
The meniscus is located on the knee. It is made up of two different tissues that are known as cartilaginous tissues. One is on top, the other is on the bottom.
Where do you read the meniscus?
The meniscus of a liquid is read at the bottom of the curve that forms at the liquid's surface in a graduated cylinder or a similar container. To determine the volume of the liquid accurately, it is important to read the measurement at the lowest point of the meniscus.
What is the meniscus rule used for?
The meniscus rule is used in chemistry to accurately measure the volume of a liquid in a graduated cylinder. It involves reading the bottom of the curved surface of the liquid level to get a more precise measurement.
What is a test tube bubble called after the measurements of liquid is poured in?
The bubble is called a meniscus. It is caused by surface tension, and usually appears as a curved surface at the top of the liquid in the test tube. To accurately measure the volume of liquid, the measurement should be taken at the bottom of the meniscus.
