There are six ways in which the word FOOT may be spelt starting at any letter.
<h3>What is combination?</h3>
The term combianntion offers a plausible way to carry out a selection as long as we do not give preference to the order in which the selection is made. In this case, we are told that we can start from any letter therefore order is not important.
There are four letters in FOOT and one letter is repeated twice therefore;
4C2 = 4!/(4-2)! 2!
4C2 = 4 * 3 * 2!/2! * 2 * 1
4C2 = 12/2
4C2 = 6

13 is a prime number so its only factors are 1 and 13
Every mixed number is (a whole number) + (a piece of another one).
So every mixed number must be bigger than ' 1 ', because ' 1 ' is the
smallest whole number.
77/200 is less than ' 1 ', because the numerator is less than the
denominator. So it doesn't have what it takes to be a whole number.
Every fraction is a short way to write a division problem. It means
(the top number) divided by (the bottom number).
When you actually do the division, the answer is the decimal form
of the fraction.
When you divide 77 by 200 , you get 0.385 .
Answer:
The surface area is 40
Step-by-step explanation:
It is 40 because you have to find the area of each face so you would do 3*4 which equals 12 and since there is 4 of the triangles you do 12*4 which is 48 but when it's a triangle you have to cut it in half so it would really be 24.
Then for the square on the bottom you would do 4*4 which is 16 and then you would add the totals to get 40.
