Jada walks up to a tank of water that can hold up to 15 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 12 gallons of water. Five minutes later, the tank contains 10 gallons of water. Type your answers in the blanks below.

At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.

How many more minutes will it take for the tank to drain completely?

minutes

How many minutes before Jada arrived was the water take completely full?

minutes

A) -2/5 gal/min

B) 25 minutes

C) 7.5 minutes

Step-by-step explanation:

A) We are told that the tank contains 12 gallons of water when Jada first sees it.

5 minutes later, it loses two gallons to become 10 gallons.

Thus, rate at which the amount of water in the tank changing = -2/5 gal/min

B) After 5 minutes it contains 10 gallons. Since it drains at 2/5 gal/min, let us say the time to finish draining all is x, thus;

2/5 • x = 10

x = 10 × 5/2

x = 25 minutes

C) When full, it can hold up to 15 gallons. This is 3 more than the 12 she saw when she arrived.

Thus;

2/5 • y = 3

y = 5 × 3/2

y = 7.5 minutes

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
