If you had 30 single socks how many pairs could you make?
If you have 30 single socks, you would be able to make 15 pairs. This is because each pair consists of two socks. So, when you divide 30 by 2, you get 15 pairs.
How many pairs of parallel sides does a circle have?
A circle does not have any pairs of parallel sides. In geometry, parallel sides are defined as sides that are always the same distance apart and will never intersect. Since a circle is a curved shape with no straight sides, it does not have any pairs of parallel sides.
Two rectangles have the same area 480m2 The difference in their lengths is 10m The difference in their widths is 4m Determine the lengths?
I would list all the factors of 480 (as pairs of numbers whose product is 480). Then find two pairs of numbers (L1,W1 and L2,W2) satisfying these properties. (It won't take long, since there are at most sqrt(480) (rounded down) pairs of numbers whose product is 480, ie. just try the numbers 1,2,3,...,21.) Hope that helps!
Find four ordered pairs for the equation x equals -5?
This first number in an ordered pair is x. And since x is always -5, all these work. (-5,0),(-5,1),(-5,2),(-5,3),(-5,4)
How many pairs of different counting numbers add to give 16?
1) 15 + 1 = 16 2) 14 + 2 = 16 3) 13 + 3 = 16 4) 12 + 4 = 16 5) 11 + 5 = 16 6) 10 + 6 = 16 7) 9 + 7 = 16 8) 8 + 8 = 16 There are 8 pairs since "0" is not counting number.
