Here is a problem that can also be solved by working backward.Alex bought twice as many pears as apples. He bought 4 more pears than oranges. He bought 6 apples.

How many oranges did Alex buy?

Final answer:

After 50 minutes, the pool has 73.74% of its initial water left, meaning it drained 26.26% of the initial water. To represent this remaining amount in gallons, it would be 0.7324 times the initial volume (in gallons).

Explanation:

To answer your question regarding the amount of water left after draining the pool for 50 minutes with a drain rate of 3% every five minutes, it is important to understand that the reduction occurs in a compound manner. This means each time we are dealing with 97% (100% - 3%) of the previous total.

So after 10 iterations (equaling to your 50 minutes since each iteration is 5 minutes long), we are left with (0.97)^10 = 73.74% of the initial total. That means 26.26% of the water has been drained.

In terms of gallons, if X represents the initial volume of water in the pool, then 0.7324 * X gallons remain after 50 minutes. Without knowing the initial volume of the pool, it is impossible to give a precise value in gallons.

Answer:

The first is a Postive slope. the Second is a Zero slope

Step-by-step explanation:

Becuase the first gradully increases. meaning positive

and the 2nd is a zero because there is no slope. it's a stright line. level ground. no up hill or down hill

Hope this helps!

Final answer:

The average change in field position per run is -2 1/4 yards. This is found by dividing the total yardage lost (6 3/4 yards) by the number of runs (3).

Explanation:

The subject of this problem is calculating the average. In this case, we are looking for the average yardage lost by the running back on each run. The running back for the Bulldogs football team has carried the ball 3 times for a total loss of 6 3/4 yards.

To find the average change in field position on each run, divide the total loss by the number of runs:

1. Convert the mixed number 6 3/4 to an improper fraction. This gives us 27/4.
2. Divide the numerator (27) by the denominator (4). This gives us -6.75.
3. Divide -6.75 by 3 (the number of runs). This gives us -2.25.
4. Convert -2.25 to a mixed number, which gives us -2 1/4.

Therefore, -2 1/4 yards is the average change in field position on each run.
