Answer:

  20 hours

Step-by-step explanation:

The volume of water when the pool is 80% full can be found using the proportion ...

  2250/75% = v/80%

  v = (80/75)(2250) = 2400 . . . cubic meters

Emptying at the rate of 120 m³/h will take ...

  time = volume/rate

  time = (2400 m³)/(120 m³/h) = 20 h

It will take 20 hours to empty the pool from 80% full.

Write the resultant of the two vectors as an ordered pair:
lubasha [3.4K]

Answer:

The resultant of the two vectors is (0,0).

Step-by-step explanation:

  • The ordered pair is : (-6,5) and (6,-5).
  • The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together.
  • The vector resultant is calculated as:

                            Abscissa of resultant= -6 + 6 = 0

                           Ordinate of the resultant= 5- 5= 0

  • Hence the resultant has the co ordinate of (0,0).

Question 27 Mike is remodeling his kitchen. The countertop he wants costs $2.80 per square foot. How much will Mike have to spen
kolezko [41]

Mike has to spend $67.20 on his remodeling project.

Explanation:

6 ft = (4 + x) ft

4+x = 6

   x = 6-4 = 2

Area 1:

S1 = 2 × (4+2)

    = 2 × 6

    = 12 ft²

Area 2:

S2 = 2 × (4+2)

     = 2 × 6

     = 12 ft²

The area of his kitchen is S1 + S2 = 12 + 12 = 24ft²

               = 24 × 2.80

               = $67.20

The image is given below for the area of the house.
