a rectangle prism is 4 units high, 2 units wide, and 6 units long. what is its surface area in square units?
Answers
SA: 2(2 × 6 + 4 × 6 + 4 × 2)
SA: 2(12 + 24 + 8)
SA: 2(36 + 8)
SA: 2(44)
SA: 88
hope that helps, God bless!
Surface area of the rectangle prism is 88 sq. units.
Given:
height of the rectangle prism (h) = 4 units
width of the rectangle prism (w) = 2 units
length of the rectangle prism (l) = 6 units
Recall:
Formula for surface area of a rectangle prism is:
[tex]SA = 2(lw +wh +lh)\\[/tex]
Plug in the values:
[tex]SA = 2(6\times 2 +2\times4 +6\times4)\\SA = 2(12 + 8 + 24)\\SA = 2(44)\\SA = 88[/tex]
Therefore, the surface area of the rectangle prism is 88 sq. units.

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 )

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.

- 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.

Answers
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.

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
(positive to negative/negative to positive for either the x or y)
hope this helps
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).

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
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.
