Answer:
C) 510 people per square kilometer
Step-by-step explanation:
Population Density = Population/Area
= 2,550,000/5000
= 2,550/5
= 510 people per square kilometer
The approximate population density of Miami-Dade County in 2011 was 510 people per square kilometer.
What is population density?Population density is a measurement of population per unit of land area.
Given that, in 2011,Miami-Dade County had a population of about 2.55 million people and covered an area of about 5000 square kilometers.
We need to find the population density of Miami-Dade County in 2011
So,
To calculate the population density, you will divide the population by the size of the area.
Thus, Population Density = Number of People/Land Area.
The unit of land area should be square miles or square kilometers.
Therefore,
= 2,550,000/5000
= 2,550/5
= 510 people per square kilometer
Hence, the approximate population density of Miami-Dade County in 2011 was 510 people per square kilometer.

which event has exactly 12 possible outcomes
Final answer:
An event with exactly 12 possible outcomes may refer to rolling a single 12-sided die, rolling two six-sided dice with one specific number on one die and any number on the other, or flipping a coin and rolling a six-sided die.
Explanation:
The event that has exactly 12 possible outcomes could be the rolling of a 12-sided die once, which would result in one of the twelve numbers coming up. Another example is rolling two six-sided dice and considering the situation where one specific number must come up on one die, while any of the six numbers could come up on the other die, thus also resulting in 12 possible outcomes (6 possible outcomes for the second die, times 1 fixed outcome for the first die), assuming the outcome of interest is only about the second die. Yet another example could be flipping a coin and rolling a six-sided die, where the coin has two possible outcomes (heads or tails) and the die has six possible outcomes, giving us a total of 12 outcomes (2 x 6 = 12).
The measures of the angles in a triangle are 1.5x, 2.4x, and 3.3x. Write an equation to determine the measure of each angle in the triangle. Use the equation to determine the exact measure of each angle in the triangle.
Answer:
[tex]37.5^{\circ}\,,\,60^{\circ}\,,\,82.5^{\circ}[/tex]
Step-by-step explanation:
Given: measures of the angles in a triangle are [tex]1.5x,2.4x,3.3x[/tex]
To find: equation to determine the measure of each angle in the triangle and exact measure of each angle in the triangle
Solution:
According to angle sum property, sum of angles of a triangle is [tex]180^{\circ}[/tex]
So, equation to determine the measure of each angle in the triangle is [tex]1.5x+2.4x+3.3x=180^{\circ}[/tex]
[tex]1.5x+2.4x+3.3x=180^{\circ}\\7.2x=180^{\circ}\\x=\frac{180^{\circ}}{7.2}=25^{\circ}[/tex]
So,
[tex]1.5x=1.5(25^{\circ})=37.5^{\circ}\\2.4x=2.4(25^{\circ})=60^{\circ}\\3.3x=3.3(25^{\circ})=82.5^{\circ}[/tex]

A submarine was located 800 feet below sea level. There is a drone
flying 250 feet above sea level over the submarine, how far apart are
the submarine and the drone?
Answer:
1,050
Step-by-step explanation:
Answer:
1050 feet
Step-by-step explanation:
The submarines location is 800 feet below which is -800 and the drones location is 250 feet above which is just 250. To get to -800 from 250 you subtract 1050 so the total distance is 1050.

solve for the unknown variable 2/5(3x-4)=-4
Answer:
x = -2
Step-by-step explanation:
Solve for x:
(2 (3 x - 4))/5 = -4
Multiply both sides of (2 (3 x - 4))/5 = -4 by 5/2:
(5×2 (3 x - 4))/(2×5) = -4×5/2
5/2×2/5 = (5×2)/(2×5):
(5×2)/(2×5) (3 x - 4) = -4×5/2
5/2 (-4) = (5 (-4))/2:
(5×2 (3 x - 4))/(2×5) = (-4×5)/2
(5×2 (3 x - 4))/(2×5) = (2×5)/(2×5)×(3 x - 4) = 3 x - 4:
3 x - 4 = (-4×5)/2
(-4)/2 = (2 (-2))/2 = -2:
3 x - 4 = 5×-2
5 (-2) = -10:
3 x - 4 = -10
Add 4 to both sides:
3 x + (4 - 4) = 4 - 10
4 - 4 = 0:
3 x = 4 - 10
4 - 10 = -6:
3 x = -6
Divide both sides of 3 x = -6 by 3:
(3 x)/3 = (-6)/3
3/3 = 1:
x = (-6)/3
The gcd of -6 and 3 is 3, so (-6)/3 = (3 (-2))/(3×1) = 3/3×-2 = -2:
Answer: x = -2

in an exponential function, (x) = a(b)^x, it is known that f(5)=15 and f(8)=170. which of the following is closest to the value of b?
(1)1.87
(2)2.25
(3)3.19
(4)3.72
Answer:
2.25
Step-by-step explanation:
5=15 and d8=170=which of the following is closest to the value of fb
The value of b is closest to (2) 2.25
An exponential function is represented as:
[tex]f(x) = a(b)^x[/tex]
[tex]f(5) = 15[/tex] means that:
[tex]ab^5 = 15[/tex] ---- equation (1)
[tex]f(8) = 170[/tex] means that:
[tex]ab^8 = 170[/tex] ---- equation (2)
Divide equation (2) by equation (1)
[tex]\frac{ab^8}{ab^5}= \frac{170}{15}[/tex]
Divide common factors
[tex]b^3= 11.33[/tex]
Take the cube root of both sides
[tex]b= \sqrt[3]{11.33}[/tex]
Evaluate the expression
[tex]b= 2.246[/tex]
2.246 can be approximated to 2.25
Hence, the value of b is closest to (2) 2.25

There is a relay race with 4 runners. The total distance run in the relay race is m
miles. Write an expression to show how far each person runs in the relay race.
In a relay race with 4 runners covering a total distance of m miles, each runner will cover an equal share of the distance, specifically m ÷ 4 miles.
Explanation:If there is a relay race with 4 runners and the total distance run is m miles, we want to find the distance each person runs. Since the total distance is divided equally among the 4 runners, we can express the distance each runner will run as:
The distance each runner runs = Total distance ÷ Number of runners
The distance each runner runs = m ÷ 4
This expression shows that each runner will run a quarter of the total distance m.
