Dimensional Analysis

Firlakuza [10]

Answer:

$5.058 USD/gal
$60.70 USD to fill the tank

Step-by-step explanation:

You want to know the cost per gallon of gas and the cost for 12 gallons of gas when the cost per liter is $1.31 CDN and the exchange rate is $1.02 USD per CAD.

<h3>Cost per gallon</h3>

The conversion between liters and gallons is ...

1 US gallon = 3.785411784 liters (exactly)

Then the cost conversion is ...

$\dfrac{\$1.31\text{ CAD}}{1\text{ L}}\times\dfrac{3.785411784\text{ L}}{1\text{ gal}}\times\dfrac{\$1.02\text{ USD}}{\$1.00\text{ CAD}}\approx\boxed{\$5.058\text{ USD/gal}}$

The cost per gallon in terms of US dollars is about $5.06.

The cost for 12 gallons will be ...

(12 gal)×($5.058 /gal) ≈ $60.70

It will cost you $60.70 to fill your 12 gallon tank.

<em>Additional comment</em>

The price of gas is routinely specified to tenths of a cent, both in the US and in Canada. As of today, the cost of gas in Canada has declined to $1.864 CAD/liter. At today's exchange rate of about $0.77 USD per CAD, the equivalent price is $5.406 USD/gal.

How many pounds.are in 96 ounces

Kryger [21]

Because we know that there are 16 ounces in a pound, we can just divide the number of ounces (96) by 16 to find out the equivalent number of pounds. 96/16 = 6 Therefore, 96 ounces is equal to 6 pounds. Hope this helps! :)

A plumber charges a fixed fee for coming to your house, then charges a fixed amount per hour on top of this. X= the time the job

Andreyy89

Step-by-step explanation:

This problem expects us to model the equation for the total cost of the services of the plumber given the conditions stated.

Say the fixed amount charged for coming to your house is $10

say the fix amount charged per is $3

and the time spent to do the job is X

Hence the scenario can be modeled as

$Y= 3x+10$

the equation is similar to the equation of a straight line

$Y= mx+c$

What advantage does a 4-in. octagon box have over a 3¼-in. octagon box?

weeeeeb [17]

Is that the whole question? What kind of advantage are we talking about here?

One possibility would be that the 4-inch box has a greater volume (capacity) than does the 3 1/4-in box. If that's the question here, then your job is to calculate the difference in volume. Find the vol. of each box and subtract the smaller from the larger to calculate the "size advantage" or "volume advantage."
