Paul's income is 40% less than Rex's income, Quentin's income is 20% less than Paul's income, and Sam's income is 40% less than

irakobra [83]

Answer:

Ratio of Quentin new income to Sam new income is $\frac{11}{12}$

So option (a) will be correct option

Step-by-step explanation:

Let Rex income is 100

Then Paul income is 40 % less than Rex income 100 - 100×0.4 = 100-40 = 60

And Quentin's income is 20 % less than Paul income

So Quentin's income is 60 - 60×0.2 = 60-12 = 48

Sam income is 40% less than Paul income

So Sam income = 60 - 60×0.4 = 60 - 24 = 36

Now Rex give 60% income Sam

So Sam new income = 36 + 100×0.6 = 60+36 = 96

And Rex give 40% of his income to Quentin's

So Quentin's new income = 48 + 100×0.4 = 40+48 = 88

Now ratio of Quentin's new income to the Sam new income $=\frac{88}{96}=\frac{11}{12}$

So option (a) will be correct answer

2 of 5<br> What is the nth term rule of the linear sequence below?<br> -9,-5, -1,3,7,...<br> Tn=

icang [17]

Answer:

$T_{n}$ = 4n - 13

Step-by-step explanation:

There is a common difference d between consecutive terms , that is

d = - 5 - (- 9) = - 1 - (- 5) = 3 - 1 = 7 - 3 = 4

This indicates the sequence is arithmetic with n th term

$T_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 9 and d = 4, thus

$T_{n}$ = - 9 + 4(n - 1) = - 9 + 4n - 4 = 4n - 13
