If there are approximately 1.8 million cars in Vancouver and if each car travels an average of 17,500 kilometres in a year, how
Goryan [66]

Rates are used to measure a quantity over another.

<em>The 1.8 million cars use </em>1.85 \times 10^{10}<em> liters each year</em>

Given

Cars = 1.8\ million

d = 17500km --- distance

r = 40miles/gallon

First, we calculate the number (n) of gallons used by each car

r = \frac{d}{n}

Solve for n

n = \frac{d}{r}

So, we have:

n = \frac{17500km}{40miles/gallon}

n = \frac{17500km}{40miles}gallon

Convert miles to kilometers

n = \frac{17500km}{40km \times 1.60934}gallon

n = \frac{17500km}{64.3738km}gallon

n = 271.85\ gallon

The number of gallons (N), used by all the cars is:

N = n \times cars

N = 271.85 \times 1.8\ million

N = 489330000

Convert to liters

N = 489330000 \times 3.78541L

N = 1852314675.3L

In scientific notation to 2 decimal places, we have:

N = 1.85 \times 10^{10}L

<em>Hence, the number of liters used is </em>1.85 \times 10^{10}<em />

I feel like it’s either answer 2 or 4. i just don’t understand the -9 part
harina [27]

Answer:

n < 27

Step-by-step explanation:

let the number be n

\frac{1}{3} n - 3 < 6 \\ add \: 3 \: to \: both \: sides \\  \frac{1}{3}n - 3 + 3  <  6 + 3 \\  \frac{1}{3} n  <  \\  9 \\ multiply \: both \: sides \: by \: 3 \\  \frac{1}{3} n  \times 3< 9 \times 3 \\ n < 27
