Leona [35]

Answer:

The statement is false

Step-by-step explanation:

we know that

if the triangle is a right triangle

c^{2}=a^{2}+b^{2}

we have

c=24\ units

a=9\ units

b=22\ units

substitute

24^{2}=9^{2}+22^{2}

576=81+484

576 \neq 565

therefore

Is not a right triangle

What is the solution to this system of equations? 3x + 2y=45 , 4x-y=5
sleet_krkn [62]
The solution is (5, 15)

Multiply the second equation by 2 and then add through. 

3x + 2y = 45
8x - 2y = 10
-----------------
11x = 55
x = 5

Then plug in to get the y value

3(5) + 2y = 45
15 + 2y = 45
2y = 30
y = 15

The population of Miami-Dade County in Florida in 2010 was 2, 496, 435 and the land area was 1, 898 square miles. The population
Jet001 [13]

The population density of the city which is the ratio of population size and the land area is 1419 people per square mile.

  • The initial population = 2496435
  • The percentage increase in population = 7.9%

  • Land Area = 1898 mi²

<u>The population of the city on 2015 can be calculated thus</u> :

  • (1 + percent increase) × initial population

  • (1 + 0.079) × 2496435 = 2693653.365 people

<u>The population of a city is calculated using the relation</u> :

  • Population density = Population / Land Area

  • Population density = 2693653.365/1898

  • Population density = 1419.21

Therefore, the population density is 1419 people per square mile.
