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 ÷ 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...
degree is the unit of either temperature or angle. But feet is the  unit 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 be  in cubic feet.   * Multiply this by the density of the base. If you have the density  in pounds per cubic foot, the answer will be in pounds.   * Convert...
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...
This is a very simple one to know that all triangles including  right angle triangle have 3 sides.   to get more help in mathematics jus visit acadsoc website and find  all your answers from a range of expert tutors.
Yes it does. The two bases (hexagons) are congruent, and the six  rectangular sides are congruen to each other.
Length is usually left to right, and the side that is not theheight or length is the width.
A straight edge is basically another name for a ruler, or it could  be 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...
one way is you could get rid of the fraction by the multiplying  everything denominator of the fraction and then just solving it  regularly.

If the two points are 'A' and 'B', you just told us that it's 170m . If 'A' and 'B' are not "the two points", then you've told us nothing about them. -------------------------- I trigonometry, we talk about "solving" a triangle. There are 6 pieces of information in triangle ABC: the 3 lengths AB,...
Dear Sir,   Please tell me that after completing post graduate certificate in  cyber law(PGCCL) from IGNOU can i appeared in UPPSC PCS-J  exam. 
You would divide by 2, then by 2 again, then again. (Because 2 to  the 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...
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).
x^2 +4x-32=0   (x-4)(x+8)=0   then x-4=0 x+8=0   x=4 x=-8
Arabia is the origin of algebra, because the work algebra comes from the Arabic word algibr.
x= -6 + square root of 7, -6 - square root of 7
Well if you're talking about one lap being 'swimming to the other  end of the pool and back again' , then it would be 85% of a mile or  0.85 of a mile, whichever one you prefer to call it :)
A nonagon is a 9 sided polygon and its 9 interior angles add up to  1260 degrees
Try to bring in shapes that are 3D, pyramid, cube, sphere, etc. Explain why the object you are holding is 3 Demensional. Try also asking them why a certain shape is 3 Dimensional, for instance, "What does a 3 Dimensional Square look like?" Let them get interactive and explain to them that a 3...
Write an essay on the impact of policy dynamics on policy changes  within the policy making process in the public sector
most common answer; 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! :-)
normally when people say "which of the following" there are actually choices following it below...
7.36649737 × 109 square feet.
An even function is symmetric about the y-axis. If a function is  symmetric about the origin, it is odd.
The point that moves (if none a new point is made) goes up or down  the graph.   Up is a positive number.   Down is a negative number.
By graphing the lines on the coordinated plane they will intersect  at (2, -4) which is the solution of the equations

The Hindu-Arabic positional system, as in every other country for at least 1500 years!
7b + 15= -34   First, 7b + 15 - 15 = -34 - 15   So, 7b = -49   Then, 7b/7 = -49/7   And finally, b = -7   So b = -7
You cannot convert square inches to inches. Square inches are units  used to measure area and inches are units of length. You cannot  convert one to the other.
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.

Scientific method is described as a scientific approach to a problem. To solve a problem you must first find the problem, access it, hypothesize a solution, illustrate your solution, try the solution, and then finally try it. If this does not work start over.
A regular pentagon can always be drawn through any two given points  with those two points as any two vertices of the pentagon.  (Diagonals of a pentagon connect two vertices which are not next to  each other.)
1,850 square feet equates to about 172 square meters.
If you're talking about two parrallel lines that have a line which  strikes through them then the term is congruent angles.
The total distance it 410 kilometers. After two hours, they are  halfway there which is 205 km from Tallahassee. They have therefore  moved at 102.5 kilometers/hour.   (If they had been driving at 105 km/h, after two hours they would  have moved a total of 210 km)    If they are currently...
They do not cross.   Lines that are parallel go in the same direction, but some distance  apart. Coplanar means they are in the same horizontal plane.  Therefore the two lines can never cross each other.

A vehicle @ 13 liters per gallon (~0.29MPG) will travel about 6.55 miles on a tank of 22.5 gallons of fuel.
It equals a positive 25, because a Negative times a Negative becomes a positive .
The formula for the area (A) of a circle is A = Ï r 2 - where r is the radius. The diameter (d) of a circle is twice the radius. The area of circle having a diameter of 24 ft is A = Ï 12 2 = 144Ï = 452.39 sq ft (2dp)
500 milligrams is 0.5 (1/2) gram.
One of the most common would be the roof of most homes and many  buildings. The rafters of the roof form a triangle, and most have  smaller triangles as part of the supporting structure to hold the  roof up, and withstand wind, snow load, and other external forces.
Their sum is 360 and the angles in opposite corners are congruent.
In hexadecimal, that would be 0x2E, which is equivalent to 46 in decimal, which in binary is 101110.

After rearranging the equation to y= 6x-42, we can find that the  slope is 6.
In a plane, each vector has only one orthogonal vector (well, two,  if you count the negative of one of them). Are you sure you don't  mean the normal vector which is orthogonal but outside the plane  (in fact, orthogonal to the plane itself)?
