Answer:
2 2/5
Step-by-step explanation:
Given 4/5÷1/3
Multiply 4/5 with the reciprocal of 1/3 as shown;
= 4/5 × 1/(1/3)
= 4/5 × 3/1
= 12/5
= 2 2/5
The quotient is 2 2/5
So 2 weeks mean
250x 2= 500
Then .50 per mile so 500 miles mean
.50 x 500= 250
In total it will be
500+250= 750
Answer:
is one to one mapping, it is not onto mapping
Step-by-step explanation:

f₁(x) is one to one mapping
Let 
f₁(x) = f₁(y):
x₁³ = y₁³
f₁(x) is not onto mapping
Example: If f₁(x) = 7,
x₁³ = 7
![x_{1} = \sqrt[3]{7}](https://tex.z-dn.net/?f=x_%7B1%7D%20%3D%20%5Csqrt%5B3%5D%7B7%7D)
x₁ is not an element of Z
is one to one mapping, it is not onto mapping
