Which statements are true? Check all that apply.
babunello [35]

Answer:

The population density for Montana can be found using the ratio 1,005,141:145,552. ; and The state with the smallest population density is Montana.

Step-by-step explanation:

Population density is found by dividing the population by the area of the state.

For Florida, this is 19317568/53927 = 358.22.

For Hawaii, this is 1392313/6423 = 216.77.

For Montana, this is 1005141/145552 = 6.91.

For Oregon, this is 3899353/95997 = 40.62.

The first statement told us the correct manner to find the population density  for Montana, so it is correct.

The second statement had the method backward for Oregon, so it is not correct.

The third statement is that the population density for Hawaii is larger than the one for Florida; this is not true, as Hawaii's is 216.77 and Florida's is 358.22.

The fourth statement is that the state with the smallest population density is Oregon; this is not true, since Montana's is 6.91 and Oregon's is 40.62.  Montana's is the smallest, so the last statement is true.

Help is this graph a function?
ale4655 [162]

Since each value of x is mapped to only one value of y, this graph represents a function.

<h3>When does a graph represent a function?</h3>

A graph represents a function when it has no vertically aligned points, that is, if <u>each value of x is mapped to only one value of y</u>.

This is one example of a graph without vertically aligned points, as if we traced vertical lines on the graph, they would cross the function only once, hence this graph represents a function.

A similar problem, in which we verify if a graph represents a function, is given at brainly.com/question/12463448

each face of a cube is a square with a side length of 8 centimeters what is the total area of the faces of the cube?
liberstina [14]

Answer:

384 cm squared

Step-by-step explanation:

The area of one side of the square is 64 cm squared since a side of the square is equal and 8 x 8 = 64. There are 6 faces on a cube so 64 x 6 = 384. Therefore, the answer is 384 cm squared.

Morgarella [4.7K]

Answer:

A. 10

B. 15

C. 116

Step-by-step explanation:

A.

f(x) = x + 10

When x is 0

f(x)= 0+10

= 10

B

f(x) = x + 10

When x is 5

f(x)= 5+10

= 15

C

f(x) = x + 10

When x is 106

f(x)= 106+10

= 116
