Micheal is 52years old today, making him 25 years older than Brain. Peter was 5 years younger than Brain and 10 years older than Jane five years ago. How old will Jane be five years from now ?

15 years old

Step-by-step explanation:

52 - 25 = 27 ( Brain's age )

25 - 5 -5 = 15 ( Peter's age 5 years ago ) so his current age is 20

5 Years Ago :

Peter was 15 and Jane was 5.

so 5 + 5 = 10

adding 5 years from now, 10 + 5 = 15

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.

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
