how ,any 2s are in a deck of cards?
There are four 2s in a deck of cards, one of each suit.
How many 2's are in a deck of 52 cards?
There are four 2s in a standard deck of playing cards.
Why is it easier to count by 5s or 10s and 2s instead of counting by 3s or 4s?
It is only because we count in tens - and 5 10 and 2 are factors.
How do you determine the equation for the perpendicular bisector of the straight line joining the points s 2s and 3s 8s?
A = (s, 2s), B = (3s, 8s) The midpoint of AB is C = [(s + 3s)/2, (2s + 8s)/2] = [4s/2, 10s/2] = (2s, 5s) Gradient of AB = (8s - 2s)/(3s - s) = 6s/2s = 3 Gradient of perpendicular to AB = -1/(slope AB) = -1/3 Now, line through C = (2s, 5s) with gradient -1/3 is y - 5s = -1/3*(x - 2s) = 1/3*(2s - x) or 3y - 15s = 2s - x or x + 3y = 17s
How many even numbers are there in a 52 card pack?
we have the numbers 1-10 on each of 4 suits of cards, the others are Jack,Kind and Queen. So there are fours 2s, fours 4s four 6s four 8s and four 10s which is 4x5 or 20 even cards.. There are also 20 odd ones, so 40 even and odd then add 4x3=12 J,K, Q and you have 52 cards
