53.9

Step-by-step explanation:

you add all of the sides up

178.07

Step-by-step explanation:

First you have to multiply 13 x 16 = 208. After that you have to find the area of the missing piece, to find that you have to add 5.7 + 6.2 = 11.9, and then subtract by 16 to get 4.1. Then you multiply 7.3 x 4.1 = 29.93.

29.93 is the area of the missing piece

So you would subtract the area of the whole thing (208) by the area of the piece (29.93)

To get the answer 178.07

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.
