A teacher asked has three students, Tom, Helen and Sandy to complete 200 exercises. The ratio of the exercises completed by Tom to the exercises completed by Helen to the exercises completed by Sandy is 3:3:4. Tom receives 8 points for each exercise. If the three students altogether receive 1240 points, how many points does Helen receive for a completed exercise?

step-by-step explanation:

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.

answer is because 4×10=40

and 98×4= is 392

40,392

35%
