There are 9 singers. They each performance 3 songs at the recital how many songs were performed?

27 songs.

Step-by-step explanation:

There were 9 singers at this recital.

Each singer performed 3 songs each.

The total number of songs performed will therefore be the number of singers multiplied by the number of songs each of them sang:

= 9 singers * 3 songs a piece

= 27 songs.

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.
