The answer of this question is 152
<span>Each team in the softball league plays each of the other teams exactly once. For every game, there is 2 team playing. The order is not important because A vs B is same as B vs A
So you just need to makes a combination of 2 that have a result of 21. If there is t number of teams, the number of matches would be:
tC2 = t!/2!(t-2)! = 21
</span>t! / (t-2)! = 21 *2
(t)(t-1)= 42
t^2 -t -42=0
(t-7)(t+6)
t=7 ; t=-6
Excluding the minus result, you got 7 teams.
Option C is correct.
try multiplying it out yourself. It should work
If ABC and DEF are complementary, then the value of x will be,
90 - ABC = x
90 - 53 = x
x = 37°
The length of the inseam to be removed from the pant is 3 2 / 3 inches.
<h3 /><h3>How to find the length to be removed?</h3>
The length of the pant he bought is 34 inches and it was too long.
He wants the length to be 30 1 / 3 inches long.
Therefore, the amount of length to be removed can be calculated as follows;
34 - 30 1 / 3

Hence,

Therefore, the number to be removed is 3 2 / 3 inches
