You select a rental package that includes a car with an average consumption of 6.00 liters of fuel per 100 km. Considering that

konstantin123 [22]

7.21 USD.

<h3>Further explanation</h3>

<u>Problem:</u>

Given in Europe, the average fuel cost is 1.063 euros/liter.
A car with an average consumption of 6.00 liters of fuel per 100 km.

<u>Question: </u>

How much (in US dollars) will we spend properly on fuel on our trip? Express the answer numerically in US dollars to three significant figures.

Let us convert the unit price from the euro to USD. Currently, the exchange rate of 1 euro is 1.13 USD.

$\boxed{ \ 1.063 \ euro \times \frac{1.13 \ USD}{1 \ euro} = 1.20119 \ USD \ }$

The term euro is crossed out.

After currency conversion, the average fuel cost is 1.20119 USD/liter.

We need 6.00 liters of fuel during the trip.

$\boxed{ \ 6.00 \ liters \times \frac{1.20119 \ USD}{1 \ liter} = 7.20714 \ USD \ }$

The term liter is crossed out.

We rounded up to three significant figures. Hence, the cost that we will spend on fuel on our trip is as much $\boxed{\boxed{ \ 7.21 \ USD \ }}$

<em>Want to follow another way? Let's see.</em>

$\boxed{ \ 6.00 \ liters \times \frac{1.063 \ euros}{1 \ liter} = 6.378 \ euro \ }$

The term liter is crossed out.

$\boxed{ \ 6.378 \ euro \times \frac{1.13 \ USD}{1 \ euro} = 7.20714 \ USD \ }$

The term euro is crossed out.

We get a similar result, i.e.,

$\boxed{\boxed{ \ 7.21 \ USD \ }}$

Answer:

1. A

2. C

3. A

4. B

Explanation:

A conductor allows electric current to pass through it. Hence, when conductors are connected in a closed circuit, current flows.

All the resistors in Q2 are connected in series. In a series connection, the current across all the resistors is the same.

In a battery, chemical energy is converted to electrical energy by chemical reactions.

When a new resistor is connected in parallel to a circuit the current increases accordingly.
