A poster is being designed that is to contain 2 150. In of printed material with margins of 2 inches at the top and bottom and 3 inches at each side. the dimensions that will minimize the amount of paper used is that should be 12 inches wide by 6 inches tall.
The margins are 2 inches at the top and bottom and 3 inches at each side. The margins are then added to the two 150s, making a total width of 12 inches and a total height of 6 inches. This is the minimum amount of paper that can be used for the poster. In order to minimize the amount of paper used, it is important to consider the size of the margins.
The margins should be kept as small as possible in order to maximize the amount of space available for the printed material. Generally speaking, a margin of 1 inch is sufficient for most printed materials. If a larger margin is necessary, then the overall dimensions of the poster should be adjusted accordingly.

A line passes through the points (–1, –5) and (4, 5). the point (a, 1) is also on the line. a coordinate plane. what is the value of a? –2 –1 1 2
The value of a is 2
We can use the slope-intercept form of a line, y = MX + b, to find the equation of the line.
The slope (m) of the line can be found using the following formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of two points on the line.
So, m = (5 - (-5)) / (4 - (-1)) = 10/5 = 2
Now, we can use the point-slope form of a line, y-y1 = m(x-x1)
where (x1,y1) is any point on the line and m is the slope of the line.
In this case, we will use the point (x1, y1) = (–1, –5)
so, y-y1 = m(x-x1) = -5 - 2(-1-x) = -5-2+2x
Now we know that the point (a,1) is also on the line, we can substitute the value of x and y in the equation
so, 1 - (-5) = 2(a - (-1))
1 +5 = 2a+2
6 = 2a+2
4 = 2a
a = 2
Therefore, the value of a is 2.

a rectangular room is 2 times as long as it is wide, and its perimeter is 36 meters. find the dimension of the room
The dimension of the room is width = 6 meters and length = 12 meters.
What is rectangle ?
A rectangle is a four-sided polygon with opposite sides that are parallel and of equal length. It has four right angles. The two parallel sides are called the length and the width. The length is the longer of the two sides, while the width is the shorter of the two sides.
Let's assume the width of the rectangular room is "w" and the length of the rectangular room is "l"
We know that the perimeter of a rectangle is the sum of twice the length and twice the width: P = 2l + 2w
Given that the perimeter is 36 meters, we can substitute that into the equation ,
36 = 2l + 2w
We also know that the length is 2 times the width, so we can substitute that into the equation: I = 2w
Now we have two equations ,
36 = 2(2w) + 2w
36 = 6w
So the width of the room is 6 meters. To find the length, we can use the information that the length is 2 times the width ,
l = 2w = 2*6 = 12 meters
So the dimension of the room is width = 6 meters and length= 12 meters.

Janice will spend $3.00 on 3 pounds of potatoes. If she only has $3.00, she will spend it all on potatoes and purchase 3 pounds of potatoes.
a) 3 pounds of potatoes
b) 3 pounds of potatoes
What is pounds?A pound is defined as 16 ounces, 7,000 grains (or 0.45359237 kg) of avoirdupois weight and 12 ounces, 5,760 grains (or 0.37324171216 kg) of troy and apothecaries' weight. The initials "lb" come from the Latin word "libra," which was the Roman equivalent of the modern "pound."
Janice can get potatoes once the price is set. As a result, she will buy those potatoes whose value is less than her willingness to pay. Her disposition to pay is what she feels the pound of potatoes is "worth". If the worth of the primary, second, and third pounds exceeds the price of the potato ($1.50, $1.14, $1.05 > $1.00), Janice will not purchase these because the worth is less than the price.

you have been told to reduce your department by 15%. your department has 220 workers. there are 512 workers in the whole company. how many workers must be let go (round to the nearest worker)?
To reduce your department by 15%, you would need to let go of 33 workers.
Reducing a department by 15% means that 15% of the current workforce in that department will be let go. To calculate this, you first need to determine the percentage of the total workforce that your department represents. In this case, your department has 220 workers out of 512 workers in the whole company, which represents 43% of the total workforce.
Then, you can calculate the number of workers that need to be let go by multiplying the total number of workers in your department by the percentage that needs to be cut. In this case, that would be
220 x 0.15 = 33 workers
This means that 33 out of the 220 workers in your department would need to be let go in order to achieve a 15% reduction.

Step-by-step explanation:
We have:

Now, we will multiply the second fraction in the first parentheses by [tex]\frac{3}{3}[/tex] so we can subtract it from the [tex]\frac{1}{15}[/tex]. Then, we will multiply all of the [tex]\frac{3}{4}[/tex]'s. This gives us:

Which simplifies to:
[tex][( \frac{1}{15} - \frac{6}{15} ) * (-\frac{27}{64})] / (-9)[/tex]
Simplifying:
[tex][(-\frac{5}{15} ) * (-\frac{27}{64})] / (-9)[/tex]
Multiplying in our brackets gives us:
[tex]\frac{9}{64} / (-9)[/tex]
Now, using the rule of KCF (Keep, Change, Flip), we will keep our first fraction, change our division sign to a multiplication sign, and make the last number its reciprocal. This gives us:

The solutions to the equation y/ (y- 4) - 4/ (y + 4) = 32/ y are approximately 30.948, 4.627 and -3.575.
The given equation is y/ (y- 4) - 4/ (y + 4) = 32/ y
Let us simplify the left hand side (LHS) :
Make the denominator same to (y - 4)(y + 4)
y/ (y- 4) - 4/ (y + 4) = (y/ (y- 4))×((y + 4)/(y + 4)) - (4/ (y + 4))×((y - 4)/(y - 4))
y/ (y- 4) - 4/ (y + 4) = ( y(y + 4) - 4(y - 4))/ (y - 4)(y + 4)
y/ (y- 4) - 4/ (y + 4) = (y² + 4y - 4y + 16)/ (y² - 16)
y/ (y- 4) - 4/ (y + 4) = (y² + 16)/ (y² - 16)
Now plugging this simplified version in LHS
(y² + 16)/ (y² - 16) = 32/ y
y(y² + 16) = 32(y² - 16)
y³ - 32y² + 16y + 32×16 = 0

The statistic that would not change if 50 points were added to each score in the SAT tests is the Standard Deviation.
What happens to the standard deviation ?The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean. By calculating the deviation of each data point from the mean, the standard deviation may be determined as the square root of variance.
The bigger the deviation within the data collection, the further the data points deviate from the mean; hence, the higher the standard deviation, the more dispersed the data.
Since they are used to determine standard deviation, sample size, mean, and data values all have an impact on standard deviation. By removing outliers, the sample size, mean, and standard deviation may all change.
Because 50 points was added to each score, they are still the same distance from each other which means the standard deviation will not change.
