How do you get 7 squares with 12 toothpicks?
7 squares is forty nine so you remove two toothpicks to make the digits 49
How many triangles are there in a three by three grid?
9 squares = 18 triangles * * * * * The correct answer is 76. There are 9 points in the grid. You can pick any 3 out of these 9 points in 9*8*7/(3*2*1) = 84 ways. However, 3 will form horizontal lines in the grid, 3 will form vertical lines in the grid, and 2 will form diagonal lines in the grid. None of these 8 triplets will form triangles, but all the rest will. So the answer is 84-8=76.
How many lines of symmetry does a heptagon have?
In general, a regular n-gon has n lines of symmetry (for odd n, each line goes through a vertex and the side opposite; for even n, half the lines go through two opposite vertices and half go through two opposite sides). A regular heptagon has 7 lines of symmetry. It has 7 symmetrical lines
Is 42 a square number using perfect squares?
No. The two closest squares are 49 and 36. The square root of 49 being 7 and the square root of 36 being 6. you can conclude that the square root of 42 isn't a perfect square, but it's square root is between 7 and 6.
What is the least and maximum number of lines obtainable with 7 points?
depends on the position of the points if points are collinear, we have just only one line, the minimum number. If points are in different position (if any of the two points are not collinear) we have 21 lines (7C2), the maximum number of lines.
How do you form two squares by drawing 7 lines?
Easy. Step one: Draw a long-enough straight line. Step two: Draw 3 lines on each half of it to form squares Done.
How can you draw squares divided into eights?
draw a square and then draw 7 lines in it
How do you get 7 squares with 12 toothpicks?
7 squares is forty nine so you remove two toothpicks to make the digits 49
What is 64xsquared - 49 in factored form?
There is a formula for the "difference of squares." In this case, the answer is (8x + 7)(8x - 7)
The sum of the squares of two consecutive negative odd integers is 74 Find the integers?
The two consecutive negative odd integers having 74 as the sum of their squares are -5 and -7.
How many triangles are there in a three by three grid?
9 squares = 18 triangles * * * * * The correct answer is 76. There are 9 points in the grid. You can pick any 3 out of these 9 points in 9*8*7/(3*2*1) = 84 ways. However, 3 will form horizontal lines in the grid, 3 will form vertical lines in the grid, and 2 will form diagonal lines in the grid. None of these 8 triplets will form triangles, but all the rest will. So the answer is 84-8=76.
Find two numbers whose difference is 3 and whose squares total 65?
4 and 7 -4 and -7
Is there a Quadrilateral with exactly 2 lines of symmetry?
There are 7 types of quadrilaterals: Kite, Trapezoid, Isosceles Trapezoid, Parallelogram, Rectangle, Rhombus, and Square.Quadrilaterals with 2 lines of symmetry:Rectangles (if they are not also a square)Rhombuses (if they are not also a square)Squares have 4 lines of symmetry.
What is a factoid for 8?
-- It's an odd power of an even number. -- It has only one prime factor, but two factors that are perfect squares. -- It's also the past tense of an act that every life form must do in order to survive. -- You can write it as two circles, two ellipses, two squares, or two parallelograms. -- You see it when you energize all 7 segments of a 7-segment digital display. -- It's the quantity of different numbers that you can write with three digital bits.
How do you factor m2 - 9?
-7
How many vertical lines in a rectangle?
7 horizontal lines and 10 vertical lines how many rectangles?
How can you solve the difference between the two perfect squares that end with 9?
49(7*7)-9(3*3) = 40
