Answer: 1200 liters per hour.

Step-by-step explanation:

Given : It takes 3 minutes to fill a 60 L bathing pool.

i.e. capacity of pool = 60 liters

Time taken to fill a 60 L bathing pool= 3 minutes

Then, the average rate in liters per minutes will be :-

\text{Average rate}=\dfrac{\text{Capacity of pool}}{\text{Time taken }}\times100\\\\ \text{i.e. Average rate}=\dfrac{60}{3}\text{ per minute}\\\\\text{i..e Average rate}=20\text{ per minute}

Since 1 hour = 60 minutes

i.e. 1 minute=\dfrac{1}{60}

Then, Average rate in liter per hour =\dfrac{20}{\dfrac{1}{60}}=20\times60\ \text{ liters per hour}=1200\text{ liters per hour}

Hence, the average rate = 1200 liters per hour.

A person has to walk 100 m to go from position X in the north of east direction to the position B and then to the west of Y to r
aleksandrvk [35]

Answer:

The distance between X and Y is 68m

Step-by-step explanation:

Consider the diagram attached:

A person starts from X, goes to Y, and then finally goes to Z, covering a total of 100m, where Z is located 60m in north of X.

We have to find distance XY.

Let the distance XY be x

Total distance covered by the person = XY + YZ

We know that total distance covered is 100m, so

100m = x + YZ

YZ = (100 - x)m

See the diagram, XZY forms a right angled triangle such that:

Hypotenuse = XY = x

Base = XZ = 60m

Perpendicular = YZ = (100-x)m

Using Pythagoras theorem

Hypotenuse² = Base² + Perpendicular²

x² = (60)² + (100-x)²

Solve the equation for x, we get:

x = 68m

A student earned grades of Upper AA​, Upper DD​, Upper AA​, Upper CC​, and Upper BB. Those courses had the corresponding numbers
dmitriy555 [2]

Answer:

  • The grade point average is 2.92
  • The student didn't make the​ Dean's list because the​ student's GPA is less than 3.0

Step-by-step explanation:

  • I take the grades as A,D,A,C,B not AA​,DD​,AA​,CC​,BB.
  • I take numbers of credit hours as 4,2,2,3,1 not as 44​, 22​, 22​, 33​, and 11.

Since quality points to letter grades are A=​4; B=​3; C=​2; D=​1; F=0, weighted mean is the sum of the qulity points times corresponding credit hours divided by the total credit hours:

\frac{(4*4) + (1*2) + (4*2) + (2*3) + (3*1)}{12} ≈ 2.92

Since 2.92<3.0, the student is not in Dean's list.

gulaghasi [49]

Answer:

Perimeter: 15 feet, Area: 15 square feet.

Step-by-step explanation:

You need this fast, so I'll spare you of much description. Add the side lengths for perimeter, and multiply the sides that aren't the hypotenuse (the legs) for the area.
