Step-by-step explanation:
The ages of Raju and Ravi are in the ratio 3:4 .Four years from now the ratio of their ages will be 4:5 . Find their present ages.
Ratio of ages at present = 3:4
Age of Raju = 3x
Age of Ravi = 4x
Age after four years:
Raju's age = 3x + 4
Ravi's age = 4x + 4
Ratio of ages after four year = 4 : 5
3x +4 : 4x + 4 = 4 : 5
(4x + 4)*4 = (3x + 4)*5
16x + 16 = 15x + 20
Subtract 16 from both sides
16x = 15x + 20 - 16
16x = 15x + 4
Subtract 15x from both sides
16x - 15x = 4
x = 4
Age of Raju = 3x = 3*4 = 12 years
Age of Ravi = 4x = 4*4 = 16 years
Answer:
0, $12.40, $24.79, $37.19, $49.58
0 ≤ f(g) ≤ 49.58
Step-by-step explanation:
The cost of fill up gas, f(g) as a function of number of gallons of gas needed (g) is given by f(g) = 2.479g ........(1)
So, f(0) = $0
f(5) = 2.479 × 5 = $12.40
f(10) = 2.479 × 10 = $24.79
f(15) = 2.479 × 15 = $37.19
and f(20) = 2.479 × 20 = $49.58
And the practical range of this function is 0 ≤ f(g) ≤ 49.58
Therefore, option D is correct. (Answer)
