The price of the shoe pair in us dollars will be $50. The correct option is C.
<h3>What is unit conversion?</h3>
Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.
It is given that shoes sell for 400 Hong Kong dollars in Hong Kong and the exchange rate is $0.125 per Hong Kong dollar. The cost of the same shoes in the united states will be calculated as below:-
Cost of shoes in the US = Cost in Hongkong x Exchange rate
Cost of shoes in the US = 400 x 0.125
Cost of shoes in the US = $50
Therefore, the price of the shoe pair in us dollars will be $50. The correct option is C.

Answer:
Im not sure but i think the answer is 7 9/15
Step-by-step explanation:
Answer:
y=x
Step-by-step explanation:
In this graph, all the x values are the same as the y values
y=x
(1,1)
(2,2)
(3,3)
(4,4)
etc..
An even function can be reflected about the y axis and map onto itself
example: y=x^2
an odd function can be reflected about the origin and map onto itself
example: y=x^3
a simple test is the following
if f(x) is even then f(-x)=f(x)
if f(x) is odd then f(-x)=-f(x)
so
even function
subsitute -x for each and see if we get the same function
remember to fully expand these
g(x)=(x-1)^2+1=x^2-2x+1+1=x^2-2x+2 is the original one
g(x)=(x-1)^2+1
g(-x)=(-x-1)^2+1
g(-x)=(1)(x+1)^2+1
g(-x)=x^2+2x+1+1
g(-x)=x^2+2x+2
not same because the original has -2x
not even
g(x)=2x^2+1
g(-x)=2(-x)^2+1
g(-x)=2x^2+1
same, it's even
g(x)=4x+2
g(-x)=4(-x)+2
g(-x)=-4x+2
not the same, not even
g(x)=2x
g(-x)=2(-x)
g(-x)=-2x
not same, not even
g(x)=2x²+1 is the even function
