This table shows the populations of the four largest cities in the state of Wyoming. How many more people live in Cheyenne than in Laramie?

Answers

Answer:

28650

Step-by-step explanation:

just subtract 59,466-30,816

The number of more people who live in Cheyenne than in Laramie given the population of each city in the state is 28,650 people

How many more people live in Cheyenne than in Laramie?

Population can be defined as the total number of people living in a particular geographical location at a period of time.

Population of Cheyenne = 59,466

Population of Laramie = 30, 816

The number of more people who live in Cheyenne than in Laramie = Population of Cheyenne - Population of Laramie

= 59,466 - 30, 816

= 28,650 people

Hence, 28,650 more people live in Cheyenne than in Laramie.

Step-by-step explanation:

In ΔOPQ, \overline{OQ} OQ ​ is extended through point Q to point R, \text{m}\angle PQR = (4x-10)^{\circ}m∠PQR=(4x−10) ∘ , \text{m}\angle OPQ = (x+9)^{\circ}m∠OPQ=(x+9) ∘ , and \text{m}\angle QOP = (x-5)^{\circ}m∠QOP=(x−5) ∘ . Find \text{m}\angle PQR.m∠PQR.

Answers

Answer:

In

In to point R, \text{m}\angle PQR = (7x-19)^{\circ}m∠PQR=(7x−19) ∘ , \text{m}\a

Step-by-step explanation:

The sum of two interior angles other than the adjacent angle of extended length will be equal to the external angle of extended length thus m∠PQR will be 18°.

What is an angle?

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

In any triangle,The sum of two interior angles other than the adjacent angle of extended length will be equal to the external angle of extended length.

In the given triangle below image,

m∠PQR = m∠OPQ + m∠POQ

4x - 10 = x + 9 + x - 5

4x - 10 = 2x + 4

2x = 14

x = 7

So,

m∠PQR = 4(7) - 10 = 18°

Hence "The measure of m∠PQR will be 18° for the given triangle".

Answer:

1A. Half jump

1B. 2/3 is half of 4/3

2. 4

Step-by-step explanation:

1A. The remainder of 2/3 is shown in the model by a half jump. It is a half jump because a full jump is 4/3.

1B. We know that the remainder represents 1/2 of the jogging loop because 2/3 is half of 4/3.

2. Convert 2 1/2 into a mixed number with the denominator as eighths. We then get 20/8 divided by 5/8. After that, we can see that 5/8 goes into 20/8 4 times. (5/8 + 5/8 + 5/8 + 5/8 = 20/8)

Answers

Answer: A, C, A, B

Step-by-step explanation:

For all of these, we can use indecy laws such as when there is a power of a power, you can multiply the powers.

Using this, we get 6^-3 x -1 or,

6^3

For the second one we get (6)^-3 x 3 or,

6^ of negative 9 which is neither.

I am guessing that the last 2 are fractions. (1/6)^-3 is equal to 216 which is 6^3.

For the last one, (1/6)^3 is basically the opposite so the answer is 6^-3.
