Answer:
13/16
Step-by-step explanation:
13 is a prime number and 16 is not a multiple of 13 so this is as simple as the fraction gets
step 1
convert miles to km
1 mile is-----> 1.60934 km
18.5 miles/hour-----> 18.5*1.60934=29.77 km/hour
step 2
convert km/hour to km/minutes
29.77 km/hour--------> 29.77/60----> 0.4962 km/minutes
step 3
by proportion
0.4962 km/1 minutes=125 km/x minutes
0.4962 km----------> 1 minute
125 km-------------> x
x=125/0.4962----> x=251.91 minutes---------> x=251.9 minutes
the answer is
251.9 minutes
Alternative Method
step 1
convert km to miles
1 km is-----> 0.621371 miles
125 km-----> 125*0.621371--->77.67 miles
step 2
convert miles/hour to miles/minutes
18.5 km/hour--------> 18.5/60----> 0.3083 miles/minutes
step 3
by proportion
0.3083 miles/1 minutes=77.67 miles/x minutes
0.3083 miles----------> 1 minute
77.67 miles-------------> x
x=77.67/0.3083----> x=251.9 minutes
Answer:
82050 people/mi^2
Step-by-step explanation:
The population of the US is 328.2 million people and the area of the US is 4000 mi^2 as given. The population density is found by (population)/(area), so we input our values in:
Population density = 328, 200, 000/4000 = 82050 people/mi^2

The relationship between cm and m is
1 cm = 0.01 m
Multiply this equation by 0.05 to get the value you want.
0.05 cm = 0.0005 m
Answer:
A number line goes from negative 10 to positive 10. An open circle appears at negative 9. The number line is shaded from negative 9 through positive 10.
Step-by-step explanation:
we have
Solve for x
Adds 7 both sides
Divide by -3 both sides
Remember that
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so
The solution is the interval (-9,∞)
therefore
A number line goes from negative 10 to positive 10. An open circle appears at negative 9. The number line is shaded from negative 9 through positive 10.
