1. A dolphin dives to 24 feet. How many fathoms is this below the surface of the water?
4 fathoms

2. 2. The deepest part of the ocean is the Marianas Trench; its depth is 11.03 km. How many feet is that?
36,399 feet

3. The largest whale measured 33.27 meters in length. How many feet is this?
109.791 ft

4. The average temperature of the oceans is 3.9° C. What is this in Fahrenheit?
39.02 °F

5. The highest tides on planet Earth occur near Wolfville, in Nova Scotia’s Minas Basin. The water level at high tide can be as much as 16 meters higher than at low tide! How many feet is this?
52.8 ft

6. Sunlight only reaches 30 to 120 meters under the waves. Convert this to feet.
99 ft to 396 ft

7. A blue whale can weight up to 280,000 pounds. That’s larger than the largest dinosaur. How many kilograms is that? (Round your answer to the nearest whole kg.)

What is this in feet? 109.791 ft

9. If all the ice in glaciers and ice sheets melted, the sea level would rise by about 80 meters, or how many feet?
264 ft

1.Convert 640 ounces into pints.

40 pts

2. If 20 shillings equal 1 pound, how many shillings does 1000 pounds equal?
1000 pounds/1 x 20 shillings/1 pound
20,000

1. How many seconds are there in 1.2 weeks?

1 week = 7 days
1 day = 24 hours
1 hour = 60 min
1 min = 60 seconds

1.2 weeks • 7 days/1 week • 24 hrs/1 day • 60 min/1 hr • 60 s/1 min = 7.3 x 105 seconds

2. If a recipe calls for 37 grams of sugar, how many pounds does that correspond to?
Given: 37 grams
Want: lbs
Know: 453.59 g = 1 lb

37 g • 1 lb/453.59 g = 8.2 x 10-2 lb

Carolyn & Bernie are going to buy a new car, which they will drive 13,000 miles a year.
They've narrowed their choices down to a Honda Civic or a Dodge Caravan.
The Honda gets 35 miles per gallon.
The Caravan gets 25 miles per gallon.
If gas is \$4 per gallon, how much money will they save on gasoline each year driving the Civic?

from ktm guest:

My old chemistry prof called it "factor-label:" You start by figuring out what you want to find out, then lay out all of your ratios and conversion factors, one multiplied by the other (always multiply, invert the relation if you need to), until you can factor out all the unwanted labels (units) in between and leave behind the ones you want. The check is that you shouldn't have any stray units hanging over when you're done.

```  dollars   4 dollars   1 gallon   13000 miles
------- = --------- * -------- * -----------
year     gallon     35 miles      1 year
```

In the numerator, you've got: dollars-gallons-miles
In the denominator: gallons-miles-year
Factor out: gallons,miles
Leaving: dollars in the numerator, years in the denominator

The "always multiply" trick bypasses figuring out complicated expressions like your first one with fractions in both the numerator and denominator.

\$2080 - \$1485 = \$595

If gasoline costs \$4/gallon, Carolyn and Bernie will save \$595 per year on gasoline if they buy the Civic instead of the Caravan.

problem #3 from Saxon 8/7 Lesson 96

The Adams' car has a 16-gallon gas tank. How many tanks of gas will the car use on a 2000-mile trip if the car averages 25 miles per gallon?
