A kid's pool had a small opening though which water leaked out sometimes. Water was poured into the pool from time to time. The graph below shows the amount of water in the pool (y), in gallons, at a certain time (x), in hours:Graph of first line going through ordered pairs 0, 40 and 2, 10. Graph of second line going through ordered pairs 2, 10 and 4, 10. Graph of third line going through ordered pairs 4, 10 and 7, 50.
Which of the following statements best describes the amount of water in the pool?
It is increasing during the time interval 4 < x < 7 hours.
It is increasing during the time interval 10 < x < 50 hours.
It is decreasing during the time interval 4 < x < 7 hours.
It is decreasing during the time interval 10 < x < 50 hours.

Answers

Answer 1

Answer:

the correct answer would be A. It is increasing during the time interval 4 < x < 7 hours.

this is because when you look at the graph, the line starts to increase at 4 on the x line and stops at 7. It (if the line goes up this mean it is increasing, if the line was going down it would be decreasing)

Allentown got 2 feet less than twice the amount of snow Georgetown got . Allentown got 3 feet more snow than Georgetown. How many feet of snow dis Allentown(x) and Georgetown (y) each get

Answers

Answer:

Allentown(x) got 8 feet of snow and Georgetown(y) got 3 feet of snow

Step-by-step explanation:

Allentown got 2 feet less than twice the amount of snow Georgetown got . Allentown got 3 feet more snow than Georgetown.

Allentown = x and Georgetown=y

To solve this we need to represent this information mathematically;

'Allentown got 2 feet less than twice the amount of snow Georgetown got' can be written mathematically as; x = 2y - 2

and

'Allentown got 3 feet more snow than Georgetown' can be mathematically written as x = y + 3

x= 2y - 2 ----------------------(1)

x = y + 3 --------------------------(2)

Subtract equation (2) from equation (1)

[ x-x=0 2y-y = y -2-3=-5]

0 = y - 5

To get the value of y, add 5 to both-side of the equation

0+ 5 = y-5+5

5=y

y=5

Substitute y=5 into equation (2)

x = y+3

x=5+3

x=8

Therefore Allentown(x) got 8 feet of snow and Georgetown(y) got 3 feet of snow

x=2y-2

x=y+3

Substitute the second equation into the first

y+3=2y-2

solve for y

y=5

plug into original

x=y+3=5+3=8 or x=2(5)-2=8

Allentown got 8 ft of snow, Georgetown got 5 ft of snow.

If a robot can travel at 4.5 meters per second, how many yards can it travel per minute

Answers

Final answer:

The robot can travel approximately 295 yards per minute, after converting its speed from meters per second to yards per minute using the conversion factor.

Explanation:

To answer this question, we need to convert the robot's speed from meters per second to yards per minute. First, we know 1 yard is approximately equivalent to 0.9144 meters. Secondly, there are 60 seconds in a minute.

The robot moves at a speed of 4.5 meters per second, multiplying that by 60 will give us the distance in meters it can cover in a minute, which equals 270 meters.

To convert 270 meters to yards, we divide by the conversion factor which is 0.9144. Thus, the robot can travel approximately 295 yards per minute.

Final answer:

To convert the speed from meters per second to yards per minute, multiply the speed in meters per second by 1.09361 (conversion factor for meters to yards) and then multiply by 60 (conversion factor for seconds to minutes).

Explanation:

To convert meters to yards, we need to use the conversion factor: 1 meter = 1.09361 yards. First, let's find out how many meters the robot can travel in one minute. Since there are 60 seconds in a minute, the robot can travel 4.5 x 60 = 270 meters in one minute. Now, let's convert meters to yards by multiplying the number of meters by the conversion factor: 270 x 1.09361 = 295.5687 yards. Therefore, the robot can travel approximately 295.5687 yards per minute.

8 + 6t - 3t + t would equal 12t^3? First one gets Brainliest Answer!

Answers

               8 + 6t - 3t + t = 12t³
                       8 + 3t + t = 12t³
            8 + 4t = 12t³
          -12t³ + 4t + 8 = 0
   -4(3t³) - 4(t) - 4(2) = 0
          -4(3t³ - t - 2) = 0
       -4 -4
            3t³ - t - 2 = 0
   3t³ + 3t² - 3t² + 2t - 3t - 2 = 0
   3t³ + 3t² + 2t - 3t² - 3t - 2 = 0
t(3t²) + t(3t) + t(2) - 1(3t²) - 1(3t) - 1(2) = 0
      t(3t² + 3t + 2) - 1(3t² + 3t + 2) = 0
      (t - 1)(3t² + 3t + 2) = 0
         t - 1 = 0 or 3t² + 3t + 2 = 0
      + 1 + 1 t = -(3) ± √((-3)² - 4(3)(2))
      t = 1 2(3)
   t = -3 ± √(9 - 24)
   6
   t = -3 ± √(-15)
      6
   t = -3 ± i√(15)
       6
   t = ⁻¹/₂ ± ¹/₆i√(15)
   t = ⁻¹/₂ + ¹/₆i√(15) or t = ⁻¹/₂ - ¹/₆i√(15)

Solution Set: {1, ⁻¹/₂ ± ¹/₆i√(15)}
