Answer:
C
Step-by-step explanation:
Parallel and opposite sides of a parallelogram are equal. Hence, we can say:
x + 30 = 2x - 10
and
2y-10 = y +10
Solving first one, we get:
x + 30 = 2x - 10
30+10 = x
x = 40
Also
2y - 10 = y + 10
y = 10 + 10
y = 20
Now, z = x - y, so
z = 40 - 20 = 20
Answer C is right.
<u>Answer:</u>
The correct answer option is B. both a function and a relation.
<u>Step-by-step explanation:</u>
We are given a from from which we can see that for each input we have exactly one output.
This means that we have a function because each element in the domain is matched with exactly one element in the range.
It is also a relation since each input related to the out put in some way.
Therefore, the correct answer option is B. both a function and a relation,
Answer:
The amount of Kroner that can be bought from 1/5 of one dollar.
Step-by-step explanation:
We have been given that goods that cost 1/5 of one dollar in the U.S. cost one kroner in Denmark. We are asked to find the the real exchange rate that would be computed as how many Danish goods per U.S. goods.
The real exchange rate tells us how much foreign currency can be exchanged for a unit of domestic currency.
It also tells us that how much the goods and services in the domestic country can be exchanged for the goods and services in a foreign country.
Therefore, the real exchange rate would be the amount of Kroner that can be bought from 1/5 of one dollar.
