Answer:

71 %

Step-by-step explanation:

Paper 1 :

65% of 120 = 0.65 X 120 = 78

Paper 2 :

80% of 80 = 0.8 X 80 = 64

Total Percentage:

Add the two scores 78 + 64 = 142

Add the what it was out of 120 + 80 = 200

Use (Score / Total marks available) X 100

(142 / 200) X 100 = 71

Which ordered pair in the form (x, y) is a solution of this equation?
Natasha2012 [34]

(3, 1)

substitute each ordered pair into the left side of the equation and if equal to the right side then it is a solution

(4, 1 )

(4 + 6) × 1 = 10 × 1 = 10 ≠ 9 ← not a solution

(2, 1 )

(2 + 6 ) × 1 = 8 × 1 = 8 ≠ 9 ← not a solution

(3, 1 )

(3 + 6 ) × 1 = 9 × 1 = 9 ← hence a solution

(12, 2 )

(12 + 6 ) × 2 = 18 × 2 = 36 ≠ 9 ← not a solution

olga nikolaevna [1]

Answer:

The volume of water remaining in the pool = 16 ft³

Step-by-step explanation:

To Determine:

What is the volume of water remaining in the pool?

Information Fetching and Solution Steps:

  • As the statement suggests the Ming family has a backyard kiddie pool with the dimensions 2 × 4 × 4 .
  • After a lot of splashing one afternoon, the pool is only half full.

As the pool contains the dimensions: 2 × 4 × 4

Volume of water in pool = length × width × depth

                                         = 2 × 4 × 4

                                         = 32 ft³

As it is stated that after a lot of splashing one afternoon, the pool is only half full.

So, the volume of water remaining in the pool will be: 32/2 = 16 ft³

                                                                               

Therefore, the volume of water remaining in the pool = 16 ft³
