53). 100 servings / 20 people = (100/20) (svngs/ppl)

   = 5 servings per person.

   Each person gets 1/20 = 5% = 0.05 of the pan.

54). 100 servings / 40 people = (100/40) (svngs/ppl)

   = 2.5 servings per person.

   Each person gets 1/40 = 2.5% = 0.025 of the pan.

55). 100 servings / 30 people = (100/30) (svngs/ppl)

      = (3 and 1/3) servings per person.

   Each person gets 1/30 = (3 and 1/3) % = 0.0333... of the pan.

To become a member at a local nature preserve, applicants must pay an initiation fee of $100 plus their yearly membership dues ,

Natalija [7]

The points are (2,150), (4,200).

The slope of the line joining the points is,

$\begin{gathered} m=\frac{200-150}{4-2} \\ =25 \end{gathered}$

Thus, the slope represents the increse in cost per year of membership.

List the potential rational zeros of the polynomial function. Do not find the zeros.

Archy [21]

$f(x)=\boxed{1}x^5-3x^2+3x+\boxed{14}$

The potential rational zeros are divisors of 14:

$\pm1;\ \pm2;\ \pm7;\ \pm14$

and the quotient p/q where p is a divisor of 1, and q is a divisor of 14:

$\pm\dfrac{1}{2};\ \pm\dfrac{1}{7};\ \pm\dfrac{1}{14}$

Complete Question:

Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. Which quantity depends on the other?

A. The distance traveled depends on the number of hours traveled.

B. The number of hours traveled depends on the speed of the train.

C. The speed of the train depends on the distance traveled.

D. The speed of the train depends on the number of hours traveled.

Answer:

Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. The distance traveled depends on the number of hours traveled

Step-by-step explanation:

As we know the velocity can de defined as the rate of change of position of objects in a particular time. The formula is given by,

$\text {velocity}=\frac{\text {distance}}{\text {time}}$

Here, in the question, rate of speed of train is given as 45 miles per hour. if we keep the velocity as constant one, then distance is directly proportionate to the travelled time

$\text {distance}=\text {velocity} \times \text {time}$

If 'v' is constant,

$\text {distance} \propto \text {time}$

By this we can conclude that, the distance travelled by the train depends on the time taken to travel to it. Hence option A would be the correct one.
