how to use a punett square?
78968
A Punnett Square, for those unaware, is the box used for determing allel (trait) combination in genetics.  A 2x2 box is the most commonly seen.  I'll use this as my example:\nDraw a square. Inside, draw a plus sign, so that you get 4 identical squares inside the larger square.\nNow, we need two 'breeders.'  Let's say Dad has brown hair, with resessive blond; Bb.  Mom is the same way; Bb.\nAt the top of the square, write Dad's alleles (the big and little 'b')...one per column.  On the left side, place Mom's alleles...one per row.\nNow, multiply.\nIn the four squares, you should end up with the following:\n1 BB\n2 Bb\n1 bb\n\nWhat does this mean?\nIt means that if Mom and Dad have 4 kids, the odds are they will have 3 with brown hair and one blond.  (Hopefully Dad understands recessive alleles, or Mom might have some explaning to do.)\n\nWill every 4th kid be blond?  No.  But, each kid will have a 1 in 4 chance of being blond, and 3 in 4 chance of being brunette.

since this starts as a square.  when we place the diagonal line from the bottom right corner to the upper left corner we end up with two right triangles.  This is the perfect set up to use the Pythagorean theorem, which states "the square of the hypotenuese is qual to the sum of the squares of the base and height. you may have seen it as \n       h^2 = x^2 + y^2\nwe started with a square so we know the base (x) and height (y) are each 7 sq rt 2.\nsquare the values then add them together.  this will give you that diagonal's square. ****remember to take the sqrt of the answer to find the length of the diagonal.

You have to find an area.  If ou have one foot by one foot, it is one square foot.  If the area is circular, find the area of the circle.

This is impossible:\nProof. Let the area of each identical square equal n^2 (so each side is n). Since the large square is has 3 of these pieces, its area is 3n^2. Thus, each of its side is sqrt(3)n. However, you can never divide the square to do this (since sqrt(3) is irrational).

We can do this 2 different ways.\n\nFirst: Use the Pythagorean Theorem. Since all angles are right angles, the diagonal (measure from corner to corner) is the hypotenuse of the right triangle formed.\n\nBy the Pythagorean Theorem, 10^2 + 10^2 =x^2, where x=diagonal\n\nx^2=200\nx=sqrt(200)\nx=10 sqrt 2\n\n2nd way: use 45-45-90 Triangles\n\nWhen you draw any diagonal in a square, you get a 45-45-90 degree right triangle. This is because the 2 sides are the same, so the 2 base angles must be also. The top is 90, so the others must be 45 and 45 to equal each other.\n\nThe sides to a 45-45-90 right triangle are always in the ratio 1:1: sqrt(2) where sqrt(2) is the hypotenuse.\n\nYou know that the sides are 10 feet. Therefore the hypotenuse is 10 sqrt2 feet

Cut a 2x2 piece off. Cut the remaining 2x3 piece in half lengthwise.  Put the two resulting 1x3 pieces one atop the other and cut the stack diagonally.  You now have 4 triangles with sides = 1, 3 and sqrt(10).  Arrange them with their right angles touching the corners of the 2x2 square piece, 3-meter sides parallel to and touching the sides of the square piece, and all "pointing" in the same direction, clockwise or counterclockwise.  The result is a square that is sqrt(10) on a side.  Area = 2x5 = sqrt(10)^2 = 10 square meters.  Three cuts were used to make five pieces.\nTo solve this I started with the requirement of the large square being sqrt(10) on a side.  Sqrt(anything) suggests the hypotenuse of a right triangle.  A little mental fiddling produced the sides of 1 and 3 meters.  Luckily a 2x2 piece remained.

I assume the shape to be rectangle.\n\nMeasure the longer side in feets and name it L\nand the shorter side as B\n\nThen multiply L*B you get measure in square feets.\n\nIf it is irregular in shape, you have to cut it into parts and draw lines and measure each area separately.

Find some 6 x 24 graph paper, or take two pieces of lined notebook paper and place them so they form squares and place them on a light box (or window).  You may need to open the curtains first.\n\nHold your 6 x 24 graph so that the 6 part runs along the bottom.  That is, hold your graph paper in "portrait mode".\nthat is like this: |, not like this __.\n\nNow label the X axis on your graph paper.  You need to know that the next whole number after -1 is 0, and then 1 and so on.  This part labels the vertical lines on the graph, and the numbers run horizontally.\n\nNow label the Y axis on your graph paper.  You need to apply the same funny rule for adding 1 to a negative number to know that the next number after -4 is -3, and so forth.  These labels are for the horizontal lines, and the numbers run vertical next to each other.\n\nYou now have a graph that labels 6 * 24 points, from (-1,-4) to (5,20).  Now you are ready to plot some of the points:\n\ny = 3x.  Substitute 0 for X.  y then = 3*0 = 0.  Thus (0,0) is a point to plot.  Place a big black spot on (0,0).\n\ny = 3x.  Substitute 1 for X.  y then = 3*1 = 3.  Thus (3,1) is a point to plot.  Place a big black spot on (3,1).\n\nRepeat this for the infinitely many solutions where y=3x fits on your graph.  You may be able to fool your teacher that you have done it infinitely many times by noticing a pattern that the spots fall on and FAKE the rest.

I'll help set it up\nbut, honesty, it isn't that hard and the only way you'll learn it is to do some on your own so that at test time, you can do it yourself...\nI'll start your homework....you finish....\n\nthe essential idea is to complete the square for each variable\nfirst reorder the terms \nx^2 - 2x +____  - 9y^2 - 18y + ___ = 9\nfactor out where possible\nx^2 - 2x + ___ - 9 (y^2  + 2y + ___) = 9\ncomplete the sq for both terms\nin case you were wondering why I put a "space" for the constant term in the working\nx^2 - 2x + 1  - 9(y^2 +2y + 1) = 9 + 1 + (-9)\nfactor\n(x - 1)^2 - 9(y+1)^2 = 1\n\nOK?????\nyou take it from here...it's almost in standard form

I can remember upto 4 to 5 ways of doing it and not more than that.  btw you are talking about halving a square (diagram)! Right ?

First pick what you want your area to be.\nLet A = 100.\nThe first one is easy, just let it be a square with all side lengths of 10\nNow pick two other numbers that when you multiply them you get 100.\n4 times 25 = 100\nA rectangle with width 4 and length 25.\nKeep picking more\n2*50 = 100\nwidth = 2 and length = 50\nYou can find more.\nAlso, you don't have to use 100, just pick any number you want for the area.

My husband and I just used geometry the other day to estimate how much tile to buy for our 2 bathrooms.  Our bathrooms have a lot of irregular spaces, so we had to measure the entire perimeter of each bathroom.  We then split the bathrooms into different geometric shapes to find the area.  We had to work our formulas for several squares, rectangles, and triangles.   Then we added them all together to come up with the square footage.  After that, we had to estimate how many 12 inch by 12 inch tiles we needed.  It was pretty tricky, but my husband is a math whiz, so it's easy for him.  He's an engineer, go figure...

just divide the inside by a perfect square (i.e. 4,9,16) and write it like this\n(this is the first problem you have)\nV(3X9) because 3X9=27\ntake the square root of the perfect square and move it to the outside\n3V3\nwhen you already have a number outside the radical, multiply it by the number you just simplified from the inside of the radical\n3V32\n3V(16X2)\n3X4V2\n12V2
