Mr Rodgers is organising a trip to a football match for 84 children. The ratio of teachers on the trip to children on the trip is 1:6 Each bus holds 30 passengers. Show four buses are needed

84/6=14

84+14=98

98/30=3.2

4 buses are needed

Step-by-step explanation:

d.192

step-by-step explanation:

12*16=192

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
