You have to multiply 3x3 since it says 3^2 then subtract 9 from 10 you get 1. Then you have to diving 8x and 1 and you get 1/8

Simlpify 3^2 to 9

9 + 8x = 10

2

Subtract 9 from both sides.

8x = 10 - 9

3

Simplify 10 - 9 to 1

8x = 1

4

Divide both sides by 8

x = 1/8

I hope this helps, and have a great day. :)

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.

The 1.8 million cars use $1.85 \times 10^{10}$ liters each year

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:

$N = 1.85 \times 10^{10}L$

Hence, the number of liters used is $1.85 \times 10^{10}$

The measurement was off by 0.7%

Step-by-step explanation:

To find the relative error in the measurement, start by finding the difference.

36 - 35.75 = 0.25

Now divide that by the actual measurement of the door.

0.25/35.75 = 0.7%
