Answer:

Julie will reach her goal 21 days ahead of Mary.

Step-by-step explanation:

Both Mary and Julie aim to raise $1000 for charity.

Mary collects $12 every 4 days.

In one day, Mary raises = \frac{12}{4}

= $3

Time required for Mary to accomplish her goal = \frac{1000}{3}

= 333.33  ≈ 334 days

Julie accumulates $19 every 6 days.

In one day, Julie raises = \frac{19}{6}

= $3.1666 ≈ $3.2

Time needed for Julie to reach her goal = \frac{1000}{3.2}

= 312.5 ≈ 313 days

Difference in the number of days to achieve their goals

= 334 - 313 = 21 days  

Hence, Julie will meet her goal first, 21 days prior to Mary.

Answer:

1/6 ton of fish is provided during the night feeding.

Step-by-step explanation:

The fish consumed in the morning is \dfrac{2}{15} tons, and the amount of fish served in the afternoon is \dfrac{1}{15} greater than in the morning. This means

\dfrac{2}{15} +\dfrac{1}{15}

Let’s represent the quantity of fish given at night as x, and if the total fish fed throughout the day equals \dfrac{1}{2}, we have

\dfrac{2}{15}+(\dfrac{2}{15} +\dfrac{1}{15})+x=\dfrac{1}{2}

By summing the numerators on the left side, we derive:

\dfrac{5}{15} +x=\dfrac{1}{2}

and subtracting \dfrac{5}{15} from both sides allows us to isolate x:

x=\dfrac{1}{2} -\dfrac{5}{15}

Since \dfrac{5}{15} =\dfrac{1}{3}, we derive

x=\dfrac{1}{2}-\dfrac{1}{3}

The common denominator for the fractions is 6; hence, we write the equation in the form

x=\dfrac{3}{6}-\dfrac{2}{6}

and simplifying the numerators results in:

\boxed{x=\dfrac{1}{6} }

which indicates the amount of tons fed during the night feeding.

Svet_ta [12734]

Initially, you must determine the circle's circumference since one complete rotation corresponds to one length of the circumference. The formula to calculate circumference is C=2πr or C=πd; for a diameter of 1 meter, the circumference equals π1, which is simply π. Therefore, if it makes 8000 rotations, the distance traveled would be 8000π meters.
