An octagonal card table has a side length of 0.67 m what is the preimeter of the table?
Octagonal table means it has 8 sides. 8*0.67 = 5.36 metres
Are the products of opposite corners of any rectangle in the multiplication table equal?
Yes.
What size rectangle table will seat 6 comfortably?
36"by 72" is a common size for six people. Two people can fit easily on the two long sides. And one person can fit on each end. If space is tight, a 30" by 60" table might also work. The key is to try to allow a minimum of 30" of table side space per person.
Why must flat- topped stoppers be laid with their flat sides on the table?
So that whatever leftover gunk happens to be on the table doesn't get all over the part of the stopper that goes into the bottle, contaminating the contents.
How do you find the other angles of a right triangle?
Using the mathematical principles of trigonometry, you will need to know the lengths of any two of the sides of the right-angled triangle in order to calculate the other angles. The ratios of the lengths can be looked up in tables (or a scientific calculator may be used) to find the angle. The three sides of a right angled triangle have names as follows:- Hypotenuse - the longest side of the triangle, opposite the right angle Adjacent - the side next to the angle you wish to know Opposite - the side opposite the angle you wish to know The ratios are named as follows:- Sine - ratio of length of Opposite divided by length of Hypotenuse Cosine - ratio of length of Adjacent dived by length of Hypotenuse Tangent - ratio of length of Opposite divided by length of Adjacent These can be remembered by the mnemonic SOH CAH TOA Depending on which sides have the known lengths, calculate the ratio and look up the value for the angle in the Sine, Cosine or Tangent table as applicable. Once the value for one angle is known, the value for the other angle is 90 minus the value of the known angle.
