Step-by-step explanation:
I think it is subtracting fractions.
First you turn the fractions into decimals then subtract it. After, you turn the decimal to a fraction but i am having a hard time doing that... the decimals by the way is 12.5 and 0.7 according to converters
Answer: There are 863,040 possible ways
Step-by-step explanation: There are 32 members altogether in the club. So in order to elect a president from among all of them, if every one of them has a chance if being elected, there would be 32 possible chances for every single club member.
However, as long as one member has been elected as president, that leaves others with a 31 chance per person arrangement.
Therefore, all possible permutations of electing four officers from a club of 32 members can be expressed as
32! (Thirty two factorial) which can be simplified as
32 x 31 x 30 x 29 and that equals 863,040.
863,040 possible ways of electing four officers from a club of 32 members.
We have P = 3 x a (the formula of the perimeter); 26 = 3 x a ; we obtain a = 26/3;
Then, we have <span>the Pythagorean Theorem in one of two rectangular and congruent triangles :</span>
h² = a² - (a/2)² = a² - a²/4 = 4a²/4 - a²/4 =<span> 3a²/4</span>
It follows that
h = √(3a²/4) = a√3/2 ≈ 0,866*a ≈ 7,5 centimeter.
