Answer:

w = 1/8t

Step-by-step explanation:

So this is basically saying that for every 1 second that passed, 8 oz of water drip steadily into the bucket which can be expressed like this:

8w = t

Since t represents x and w represents y, we can simplify the equation by moving the 8 to the other side

w = 1/8t

triumphant college is planning to increase the registration fee by 11.5%.if the registration fee is currently N$ 1000, how much
frozen [14]

Current registration fee at triumphant college = N$ 1000

Percentage by which the registration fee will be increased next year = 11.5%

Registration fee at triumphant college next year :

= Current registration fee + 11.5% of current registration fee

=\tt1000 +  \frac{115}{10 \times 100}  \:  \: of \:  \: 1000

= \tt1000 +  \frac{115}{1000}  \times 1000

=\tt 1000 +  \frac{115000}{1000}

=\tt 1000 + 115

\color{plum} = \tt \:\bold{ N\$ \: 1115}

Therefore, the registration fee at triumphant college next year = <u>N$ 1115</u>

The table shows the year groups of some students who use the canteen. Mr Ford wants to survey 50 of these students stratified by
igor_vitrenko [27]

7 more year 9 students than year 8 students should be surveyed, If Mr.Ford wants to survey 50 of these students stratified by year group.

Step-by-step explanation:

The given is,

                    Year                        Students

                       7                                 80

                       8                                 110

                       9                                 160

                    Total                              350

           Mr.Ford wants to survey 50 of these students stratified by year group.

Step:1

           Formula to find the ratio of number of grouped students to total students,

                           Ratio, r = \frac{Number of students grouped }{Total number of students}

                                         = \frac{50}{350}

                                         = 0.1428

Step:2

          Formula for Number of students surveyed from year wise,

          For year 7 students,

                                         = (Ratio) × (Students from year 7)

                                         = 0.1428 × 80

                                         = 11.424

                                        ≅ 11               (∵ For students we convert into whole number)

         For year 8 students,

                                         = (Ratio) × (Students from year 8 )

                                         = 0.1428 × 110

                                         = 15.708

                                        ≅ 16               (∵ For students we convert into whole number)

          For year 8 students,

                                         = (Ratio) × (Students from year 9 )

                                         = 0.1428 × 160

                                         = 22.8

                                        ≅ 23             (∵ For students we convert into whole number)

Step:3

          To find How many more year 9 students than year 8 students should be in the survey

                                        = ( Students from year 8 for group) -

                                                                     ( Students from year 8 for group)

                                        = 23 - 16

                                        = 7 students

Result:

          7 more year 9 students than year 8 students should be surveyed, If Mr.Ford wants to survey 50 of these students stratified by year group.
