What is energy? List three common units of energy. Under what circumstances do the different
units tend to be used? - ANS-Energy is what makes matter move or heat up.
List three common units of energy. Under what circumstances do the different units tend to be
used? - ANS-Kilowatt-hour; used to measure electrical energy for utility bills.
Calorie; used to measure the energy the human body can draw from food.
Joule; the international metric unit for energy.
Decide whether the following statement makes sense (or is clearly true) or does not make sense
(or is clearly false). Explain your reasoning. Be sure to consider whether the units are
appropriate to the statement, as well as whether the stated amount makes any sense.
For example, a statement that someone is 15 feet tall uses the units (feet) appropriately, but
does not make sense because no one is that tall.
I drank 1.3 liters of water today. - ANS-This statement makes sense because
1.3
liters=0.3
gallon(s), which is a reasonable amount of water to drink in one day.

I know a professional bi-cyclist who weighs
210
kilograms. - ANS-This statement does not make sense because
210210
kilograms=463
pound(s), which is an unreasonable weight for a professional bicyclist.
Evaluate the following expressions. - ANS-10⁸×10⁷=10¹⁵
10⁹x10⁻³=10⁶
10⁴/10²=10²
10¹²x/10⁻⁴=10¹⁶
Evaluate the following expressions. - ANS-10¹⁸/10¹²=10⁶
10¹+10⁰=11
10³+10⁻²=1000.010³-10²=900
A certain race is a distance of 38 furlongs. How far is the race in (a) miles? (b) yards? - ANS-The
race is
4.75
mile(s).
,The race is
8360
yard(s).
One cubic foot holds 7.48 gallons of water, and 1 gallon of water weighs 8.33 pounds. How
much does
6.7
cubic
feet
of water weigh in pounds? In tons? - ANS-The weight in pounds is approximately 417.5 lb.
(Round to the nearest tenth as needed.)
The weight in tons is approximately 0.21 ton(s).
(Round to the nearest hundredth as needed.)
Decide which of the two given prices is the better deal and explain why.
You can fill a 1515-gallon tank of gas for $40.01 or buy gas for $2.70/gallon. - ANS-The better
deal is to
fill a 15-gallon tank for $40.01
because the price to fill a
15-gallon
tank of gas for
$40.01
is
$2.67
per gallon.
, Decide which of the two given prices is better and explain why. Storage locker A rents for
StartFraction $ 34/yd²
per month. Storage locker B rents for $ 1.97/ ft²
per week.
Assume 1 month=4 weeks.) - ANS-Storage locker A is the better deal because after converting
to the units of B's rental price the cost of locker A is $.94/ft² per week which is cheaper than
B's rental cost of $1.97/ft²per week
Complete the following sentence with a power of ten greater than 1.
A terameter is _______ times as large as a meter. - ANS-A terameter
is 10¹² times as large as a meter.
Complete the following sentence with a power of ten greater than 1.
A liter is _______ times as large as a
microliter. - ANS-A liter is
10⁶ times as large as a microliter.
Convert the measurement to the units specified.
16 pounds to kilograms - ANS-16 pounds = 7.26 kg.
Convert the following quantities to the indicated units. 19 square kilometers
to square miles - ANS-19 square kilometers=7.3
square mile(s)
