Jada walks up to a tank of water that can hold up to 12 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 8 gallons of water. Four minutes later, the tank contains 5 gallons of water.
A) 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.
B) How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
C) How many minutes before Jada arrived was the water tank completely full? Explain or show your reasoning.
Answers
2) we have 5 gallons and lose 2/3 gallons per minute
(2/3 gal/minute)(x minutes) = 5 gallons
x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons
3) There was 10 gallons when the tank is full
That is 3 gallons more than the 7 gals there when Jada arrived.
(2/3)(x) = 3
x = 3(3/2) = 9/2 = 4 1/2 minutes
The tank was full 4 1/2 minutes before Jada arrived
gallons per minute since it decreases by 2
gallons in 3 minutes
2) we have 5 gallons and lose 2/3 gallons
per minute
(2/3 gal/minute) (x minutes) = 5 gallons
X=5(3/2) = 15/2 =7.5 minutes to drain the
other 5 gallons
3) There was 10 gallons when the tank is
full
That is 3 gallons more than the 7 gals
there when Jada arrived.
(2/3)(x) = 3
x=3(3/2) = 9/2 = 4 1/2 minutes
The tank was full 4 1/2 minutes before
Jada arrived

Step-by-step explanation:
{4x−2y=102x−y=5
{y=2x−3−2x+y=−5
{2x−5y=143x+4y=10
The system of equations 2x−5y=14 and 3x+4y=10 have unique solution, so they are consistent independent.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
A) The given system of equations are 4x−2y=10 and 2x−y=5
4/2 = (-2)/(-1)=10/5
2=2=2
Since, a₁/a₂ =b₁/b₂=c₁/c₂
The system of equations have infinitely many solution, so they are consistent dependent.
B) y=2x-3 and -2x+y=-5
Here, 2x-y-3=0 and -2x+y+5=0
2/(-2)=(-1)/1≠(-3)/5
-1=-1≠(-3)/5
Since, a₁/a₂ =b₁/b₂≠c₁/c₂
The system of equations are parallel, so they are inconsistent equations.
C) 2x−5y=14 and 3x+4y=10
Here, 2x-5y-14=0 and 3x+4y-10=0
2/3≠(-5)/4≠(-14)/(-10)
Since, a₁/a₂ ≠b₁/b₂
The system of equations have unique solution, so they are consistent independent.
Therefore, the system of equations 2x−5y=14 and 3x+4y=10 have unique solution, so they are consistent independent.

A quadrilateral has 4 sides and 4 angles which both shapes do. The next 2 and the last one are correct because squares are classified with the rules. All sides are equal, all angles are the same size and have all parallel sides. Rhombuses are called rhombuses because they have all sides measuring same length, opposite angles are equal, have 4 angles, and opposite sides are parallel.
The correct statements are :
1) Both shapes are quadrilaterals.
2) Both shapes have all sides of equal lengths.
3) Both shapes have four right angles.

There were 1150 pounds of flour in the grain store. After most of the flour was sold, there were 230 pounds left. What was the percentage decrease of the grain store’s flour?
Answers
9514 1404 393
Answer:
80% decrease
Step-by-step explanation:
The percentage change is found from ...
percent change = ((new value)/(old value) -1) × 100%
= (230/1150 -1) × 100%
= -0.8 × 100%
= -80% . . . . . a negative change is a decrease
The store's flour quantity decreased by 80%.

The solution is, It is not reasonable to say they can carry 15 feet with each person taking only one turn.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
given that,
Kevin=5 feet
Rachel=3 feet further than Kevin=(3+5)=8 feet
Daniel=half as far as Rachel=(1/2)×8=4 feet
If each person takes one turn;
Total distance covered=(Kevin's distance+Rachel's distance+Daniel's distance)
Replacing;
Total distance covered=(5+8+4)=17 feet
17 feet≠15 feet
It is not reasonable to say they can carry 15 feet with each person taking only one turn.
