Convert the following two densities to grams per cubic centimeter to determine which mineral is more dense.
Galena has a density of 0.0074 kilograms per cubic centimeter
Tiger's Eye has a density of 2640 kilograms per cubic meter
(1 point)
Galena has a density of 7.5 grams per cubic centimeter, which is more dense than Tiger's Eye at 2.64 grams per cubic centimeter
Galena has a density of 70.4 grams per cubic centimeter, which is more dense than Tiger's Eye at 20.64 grams per cubic centimeter
Galena has a density of 20.64 grams per cubic centimeter, which is less dense than Tiger's Eye at 70.4 grams per cubic centimeter.
Galena has a density of 0.74 grams per cubic centimeter, which is less dense than Tiger's Eye at 2.64 grams per cubic centimeter
The correct answer is:
Galena has a density of 7.4 grams per cubic centimeter, which is more dense than Tiger's Eye at 2.64 grams per cubic centimeter.
If Jaime is riding at 14 miles per hour and Cori is riding at 0 40 kilometers per minute, how far will each of them bike in two hours?
1 mile is equivalent to 1.61 kilometers
Use the equation d = ut
(1 point)
• Jaime will bike 29.82 miles and Cori will bike 28 miles
• Jaime will bike 28 miles and Cori will bike 38.64 miles
• Jaime will bike 38.64 miles and Cori will bike 28 miles
• Jaime will bike 28 miles and Cori will bike 29.82 miles
page 13 of 13
To find the distance each person will bike, we can use the formula d = ut, where d is the distance, u is the speed, and t is the time.
For Jaime:
d = 14 miles/hour * 2 hours
d = 28 miles
For Cori:
First, we need to convert Cori's speed from kilometers per minute to kilometers per hour.
Cori's speed = 40 kilometers/minute * 60 minutes/hour
Cori's speed = 2400 kilometers/hour
Now we can find the distance for Cori:
d = 2400 kilometers/hour * 2 hours
d = 4800 kilometers
However, we need to convert Cori's distance to miles, since Jaime's distance is given in miles.
Cori's distance = 4800 kilometers * (1 mile / 1.61 kilometers)
Cori's distance ≈ 2981.37 miles
Therefore, the correct answer is:
Jaime will bike 28 miles and Cori will bike approximately 2981.37 miles.
Two taxi companies in a city only charge by mileage and do not charge an initial fee. If Taxi 1 charges $3.00 per mile and Taxi 2 charges $1.77 per kilometer. Determine how much a 12 mile ride will cost in each taxi.
There are 1.61 kilometers in every mile
(1 point)
© A 12 mile ride in Taxi 1 costs $34.00 and in Taxi 2 costs $34.20
© A 12 mile ride in Taxi 1 costs $34.20 and in Taxi 2 costs $36.00
• A 12 mile ride in Taxi 1 costs $36.00 and in Taxi 2 costs $34.20
© A 12 mile ride in Taxi 1 costs $36.00 and in Taxi 2 costs $13.19
To find the cost of a ride in each taxi, we need to multiply the distance by the respective rate.
For Taxi 1:
Cost of a 12-mile ride = $3.00/mile * 12 miles
Cost of a 12-mile ride = $36.00
For Taxi 2:
Convert the distance from miles to kilometers:
12 miles * 1.61 kilometers/mile = 19.32 kilometers
Cost of a 19.32-kilometer ride = $1.77/kilometer * 19.32 kilometers
Cost of a 19.32-kilometer ride ≈ $34.20
Therefore, the correct answer is:
A 12-mile ride in Taxi 1 costs $36.00 and in Taxi 2 costs approximately $34.20.
