The population in the South in 2000was 100,236,820. In 2010 the population increased by 14.3% from 2000. How many people live in the south in 2010

Answers

First get the percentage of increase by changing 14.3 percent to a decimal and multiplying 100,236,820 by .143

100,236,820 x .143 = 14,333,865

Now add 100,236,820 by 14,333,865
100,236,820 + 14,333,865 = 114,570,685

If a television screen with a length-to-height ratio of 16:9 has an area of 576in, what is it's perimeter?

Answers

Final answer:

The perimeter of the television screen is 100 inches.

Explanation:

To determine the perimeter of a television screen with a length-to-height ratio of 16:9 and an area of 576 square inches, we need to find the length and the height of the screen first.

Using the ratio, we let the length be 16x and the height be 9x.

The area of a rectangle is given by its length times its height, so we have:

(16x) × (9x) = 57

144x² = 576

x² = 576 / 144

x² = 4

x = 2

Now we can find the actual dimensions:

Length = 16 × 2 = 32 inches

Height = 9 × 2 = 18 inches

The perimeter (P) of a rectangle is given by

P = 2 × (Length + Height)

P = 2 × (32 + 18)

P = 2 × 50

P = 100 inches

The perimeter of the television screen is 100 inches.

A road sign gives drivers information about traffic on busy highways. One sign shows "15 miles in 20 minutes". What is this speed in miles pee hours?

Answers

First of all you need to work out 20 minutes in hours, this can be done by dividing 20 by 60:
20/60 = 1/3

Then you need to divide 15 by 1/3 to get the final speed:
15 / 1/3 = 45 miles per hour

He will need to be traveling at 45 miles per hour,
Hope this helps! :)

15/20 = mph/60

60 x 15 = 20 x mph

900 = 20 x mph

900/20 = mph

45mph is your answer.

after a reflection over the line y=x (8,11) is the image of point c. what is the original location of point c

Answers

the original points/point c would be (-8,11) bc the y stays the same and the x changes from its original to (in this case) negative to positive

(positive to negative/negative to positive for either the x or y)

hope this helps

Final answer:

The original location of point C before a reflection over the line y=x, given that the image of point C is at (8,11), would be (11,8) as coordinates are swapped during such a reflection.

Explanation:

To determine the original location of point C before a reflection over the line y=x, you would apply a simple transformation rule. For any reflection over the line y=x, the coordinates of a point are swapped. Thus, if the image of point C is at (8,11), the original location of point C would have the x-coordinate as 11 and the y-coordinate as 8.

The step-by-step process to find the original location of point C before the reflection is as follows:

Take the x-coordinate of the image and make it the y-coordinate of the original point.Take the y-coordinate of the image and make it the x-coordinate of the original point.The resulting point is the original location of C before the reflection.

Therefore, the original location of point C is (11, 8).

Answer:

Mary's improved math performance after seeing it as a fun challenge reflects a growth mindset, believing in the ability to develop skills through effort and dedication.

Explanation:

Mary's improved performance in math after deciding to think of it as a fun challenge is an example of the power of mindset, specifically a growth mindset. A growth mindset is the belief that abilities and intelligence can be developed through dedication and hard work. By shifting her perspective and viewing math as a fun challenge rather than something she was inherently bad at, Mary adopted a growth mindset. This change in mindset likely led her to approach math with more enthusiasm, effort, and persistence, ultimately resulting in improved performance.

Can someone help me? (Algebra 1)

Answers

I believe real and rational.

Let's find out what the following terms mean, so we know what to choose from:

- An irrational number is a number that cannot be represented by a simple fraction. They can't be written as a ratio with two integers (like 55 = 55/1, 1.5 = 3/2, -.25 = -3/4). They are unable to repeat, and unable to end. Pi (3.1415926...) is a notable example of an irrational number. 1.7 as a fraction is 17/10. It can be written as a ratio with two integers, so it is not irrational.

- A real number is a number that represents any quantity in a number line. It includes all numbers. Every number is a real number. So, 1.7 is a real number.

- A whole number is a positive number (including 0) that does not include any fractions, decimals, radicals, etc. Numbers such as 5, 32 and 73 are considered whole numbers. 1.7 is not a whole number, since it is a decimal.

- A rational number is a number that can be written as a fraction. Values such as whole numbers (ex: 3/1), negative numbers (ex: -7/1), decimals that can be successfully written as a ratio (ex: .5) are rational numbers. Unlike irrational numbers, these can end (3.4) and repeat (3.3333333333...). 1.7 is able to be written out as a fraction with two integers and it ends. It is a rational number.

- A natural number is a positive whole number. So, naturals are greater than 0. numbers such as 1,2,3 and onward are natural numbers. 1.7 is a decimal; it is not considered a natural number.

- Integers are all the positive and negative whole numbers including zero. 123, -5000, and 34 are random examples of an integer. 1.7 is a decimal, so it is not an integer.

If the unit selling price is 2.50 and the unit cost is 1.00 what action is needed to maintain the gross margin percentage when unit cost increase 0.25

Answers

The original gross margin is (2.50 / 1.00) - 1 = (2.5 - 1) = 1.5 = 150%

the cost increases 0.25, is an increase of (0.25 / 1.00) = 25%

in order to keep the same gross margin, you need to increase the sale price by 25%

2.50*1.25 = 3.125

Then the gross margin is (3.125 / 1.25) - 1 = (2.5 - 1) = 1.5 = 150% ( same as original )

A referee was standing on a certain yard line as the 1st quarter ended. He walked 41 3/4 yards to a yard line with the same number as the one he just left. How far was the refree from the nearest goal

Answers

Refer to the diagram shown below.

The American football field is 100 yds long, 53 1/3 yards wide, and has 10-yard touchdown zones at each end of the field.

Let x = distance of the referee at the end of the quarter from the nearest goal.
The distance between the same yard lines on either side of the center line is
100 - 2x

This distance is the 41 3/4 yards that the referee walked. Therefore
100 - 2x = 41.75
-2x = 41.75 - 100 = -58.25
x = 29.125 yd (or 29 1/8 yd)

Answer:
The referee was 29 1/8 yards (or 29.125 yards) from the nearest goal.

Every whole number is a rational number: for example, 3=31. So it is rational. Every whole number n can be written as a fraction of integers: n=n1. We aren't required to write it that way; we just need to know that it is possible to express every whole number as a fraction of integers, and hence it is rational.
