C = d where C is the circumference of a circle, is about 3.14, and d is the diameter.

Rzqust [24]

Answer:

Formula for Circumference of a Circle

Circumference is given by the formula C = πd where π = 3.14 and d is the diameter of the circle. Circumference is given by the formula C = 2πr where π = 3.14 and r is the radius of the circle.

What value of x satisfies the equation x/6-1/5=7/30

Makovka662 [10]

We need to isolate x in order to find x. However, we need to have common denominators first.
$\frac{5x}{30}- \frac{6}{30} = \frac{7}{30}$
$\frac{5x}{30}= \frac{13}{30}$
Multiply by 30 on both sides.
$5x=13$
Divide by 5 on both sides to isolate x.
$x= \frac{13}{5}$

There are 25 students that would like to go on a field trip, but only 18 may go. How many different combinations of students cou

Naya [18.7K]

480700. The different combinations of students that could go on the trip with a total of 25 student, but only 18 may go, is 480700.

The key to solve this problem is using the combination formula $nC_{r}=\frac{n!}{r!(n-r)!}$ . This mean the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed.

The total of students is n and the only that 18 students may go is r:

$25C_{18}=\frac{25!}{18!(7!)}=480700$
