The use of letters to substitute unknown numbers to form an equation. Solve the equation to get the unknown number using different methods such as simultaneous equations and more.

The length of a midsegment is half that of the parallel side of the triangle; assuming the midsegment is parallel to the [given] base, then its length is 27 Ã· 2 = 13.5 units.

0.25 no, 0.25 (or 1/4), is the reciprocal of 4. the reciprocal of 25 is 1/25

A ratio is a comparison between two quantities. Ratio is the quantitative relation between two different amountsshowing the number of times one value is contained within theother. To solve, you have to make each side of the ration equal,like an even scale. Adding further it is the value of relation...

You bring it straight down.

degree is the unit of either temperature or angle. But feet is theunit of length. So no relation between these two

You can calculate as follows: * Convert the 4 inches to feet. * Multiply the area by the thickness. The result, so far, will bein cubic feet. * Multiply this by the density of the base. If you have the densityin pounds per cubic foot, the answer will be in pounds. * Convert that to pounds.

-- square the point's x-coordinate -- square the point's y-coordinate -- add the two squares together -- take the square-root of the sum -- the answer is the distance of the point from the origin. This works because if you draw a line down from the point to thex-axis (length is y-coordinate), then...

An asymptote of a curve is a line where the distance of the curveand line approach zero as they tend to infinity (they get closerand closer without ever meeting) If one zooms out of a hyperbola, the straight lines are usuallyasymptotes as they get closer and closer to a specific point, yetdo not...

In referring to blood, the four major components that make up wholeblood are RBC's, WBC's, Plasma and Platelets. Fractions areincluded in each of the 4 components. Examples include: ImmuneGlobulins, Albumin, Clotting Factors etc.

This is a very simple one to know that all triangles includingright angle triangle have 3 sides. to get more help in mathematics jus visit acadsoc website and findall your answers from a range of expert tutors.

Yes it does. The two bases (hexagons) are congruent, and the sixrectangular sides are congruen to each other.

Length is usually left to right, and the side that is not theheight or length is the width.

The radius is directly related to the circumference of a circle by C=Ï 2R so it would get proportionately larger as the circumference grows. If you start with C=Ï 2R where 2R=C/Ï then change C to C 2 =3C then 2R 2 becomes C 2 /Ï or 3(2R)/Ï

You need to know the density o f Mg D = Mass/Volume Mass = Density * volume Density= 1.74 grams per cubic centimeter Volume = 2.5 * 3.5 * 1.5 Mass = Density * volume

A straight edge is basically another name for a ruler, or it couldbe anything that makes straight lines.

Because when there is a positive and a negative in the same problem, it gives you a negative. An easy way to solve problems like that is if there is an odd number of negative signs, then your answer is going to be negative. If there is an even number of negative signs, then your answer is going to...

36 square units. You can't express a perimeter in square units; a perimeter is a length expressed in ordinary units. If the perimeter of this square is 24 units then the answer above is correct.

one way is you could get rid of the fraction by the multiplyingeverything denominator of the fraction and then just solving itregularly.

You would divide by 2, then by 2 again, then again. (Because 2 tothe 3 is 8)

Feet to Linear Feet? Question not Clear .
100 Feet IS 100 Linear Feet..
If you wanted to know how many linear feet would give you 100 square feet, you would take the square root of 100, which is 10... SO a 10 x 10 linear foot area would be 100 square feet, and a 100 x 100 Linear foot area would...

I am not really sure what you are asking for, but any intercept onthe x -axis has a y value of 0, so for any particular x value N , the intercept is at ( N , 0).

The '0' value is correct - a constant speed or velocity (notsynonyms) is one of no acceleration or deceleration - but it's notthe "most common" answer, it is THE answer! :-)

One of the most confusing and misleading metrics in the homebuilding and home selling business is area - the "size" of ahouse. The problem is that there's no adopted standard; everyone measuresit differently. There has been a move in the past few years tocreate a universal standard like the one...

7b + 15= -3 4 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7

Parallelogram

You cannot convert square inches to inches. Square inches are unitsused to measure area and inches are units of length. You cannotconvert one to the other.

Multiply 9*16 to see how much it would measure in square meters.Then, multiply it by 1.25 which is the cost of each square meter.

No. Work and power are different. There is quite a good chance that the one with twice the power will do more work, though.

if x = -6 and y = 4 - x, then y = 4 - (-6) = 4 + 6 = 10.

1,850 square feet equates to about 172 square meters.

Circumference is pi times diameter. If the radius is 24, the diameter (twice the radius) is 48, making the circumference 48pi, or approximately 150.72 units.

If you're talking about two parrallel lines that have a line whichstrikes through them then the term is congruent angles.

Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.

They do not cross. Lines that are parallel go in the same direction, but some distanceapart. Coplanar means they are in the same horizontal plane.Therefore the two lines can never cross each other.
