A local sports center charges $8 per

visit. For an annual membership

fee of $45, the cost per visit is only

$5.50. What is the least number of

visits needed in a year in order for the

membership to be a better deal?

The minimum number of visits required in a year to the local sports center for the annual membership to be a better deal is 19.

Step-by-step explanation:

The charges to a local sports center is $8 per visit.

In case of an annual membership a fee of $45 is collected and a fee of $5.50 is charged per visit.

Let x be the least number of visits required to the sports center in order for the membership to be a better deal.

Therefore we can now equate the two as shown below.

    $8 × x  = $45 + ($5.50 × x)

Now solving for x we get           ⇒ 8x - 5.5x  = 45

                                                    ⇒  2.5x = 45

                                                    ∴  

Therefore the minimum number of visits required in a year to the local sports center for the annual membership to be a better deal is 19.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
