This is a scale drawing of an apartment. The actual apartment has a perimeter of 160 ft. Draw another scale drawing of the apartment using the scale 20 ft to 1 unit from the apartment to the drawing Explain your reasoning
pls help someone
According to the scale factor, When the scale is changed to 20 feet to 1 unit, then the drawing would be exactly the same shape, here only each side would have half the original drawing units.
Scale factor:
The ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller) is known as scale factor.
Given,
This is a scale drawing of an apartment. The actual apartment has a perimeter of 160 ft.
Here we need to find the reason for the scale drawing of the apartment using the scale 20 feet to 1 unit from the apartment
Here we know that the actual apartment has a perimeter of 160 ft.
And we have to draw another scale drawing of the apartment using the scale 20 feet to 1 unit from the apartment to the drawing.
So, as per the given details, the perimeter lies along the edges of squares and we count 16 sides of squares as we work around the perimeter, this means that each square is calculated as,
=> 160 / 16 = 10 feet on a side.
Therefore, 10 feet in real life plots to 1 unit on the drawing
Therefore, if we change the scale to 20 feet to 1 unit , then the drawing would be exactly the same shape, only each side would have half the original drawing units.

The length of the rectangular lot is 25 ft longer than twice the width. If the perimeter of the lot cannot exceed 350 ft, what is the greatest width possible?
The greatest width possible if the length of the rectangular lot is 25 ft longer than twice the width and if the perimeter of the lot cannot exceed 350 ft is 50 ft.
We are given,
The length of the rectangular lot is 25 ft longer than twice the width.
The perimeter of the lot cannot exceed 350 ft.
Let the width of the rectangular lot be x.
So, the length of the rectangular lot = 2x + 25
We know that the perimeter of the rectangle is given by:
P = 2(L + W)
Substitute the given values in the above formula;
350 = 2(2x +25 + x)
350 / 2 = 3x + 25
175 - 25 = 3x
x = 150 / 3
x = 50 ft
So, the width of the rectangular lot = 50 ft
And, the length of the rectangular lot = 2 * 50 + 25 = 125
Thus, the greatest width possible if the length of the rectangular lot is 25 ft longer than twice the width and if the perimeter of the lot cannot exceed 350 ft is 50 ft.

What is the equation for the line that is perpendicular to y=−1/2x+5 and passes through the point (0, 7)?
The equation of line passes through the point (0, 7) will be;
⇒ y = 1/2x + 7
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (0, 7).
And, The perpendicular line is,
⇒ y = -1/2x + 5
Now,
Since, The equation of line passes through the point (0, 7).
So, We need to find the slope of the line.
Since, The product of slope of the perpendicular lines is - 1.
Hence, Slope of the perpendicular line is,
y = -1/2x + 5
m₁ = dy/dx = - 1/2
m₁ = - 1/2
So, The slope of the line,
m₂ = - (- 1/2)
= 1 / 2
Thus, The equation of line with slope 1/2 is,
⇒ y - 7 = 1/2 (x - 0)
⇒ y - 7 = 1/2 x
⇒ y = 1/2x + 7
Therefore, The equation of line passes through the point (0, 7) will be;

Answer:
Step-by-step explanation:
Hi, Julia, they are trying to ask about error, or the confidence that there is not an error. It's kinda like saying, we're 100% sure the answer is correct, mostly :DDDD which really lowers your confidence about the 100% correct statement. Anyway, sooo then they give the way to show deviation, from something. if you've had Calculus one, this is the same thing as the Delta , Epsilon thing, about a small distance away from the target is still with in a certain range. I feel like if they had written the inequality like this...
( p' - E) < p < (p'+E) it would be clearer about the inequality. E is just a tiny distance away in the positive and negative direction. E plays the role of epsilon. the numbers they give are the range of the confidence. I don't think they ask a very clear question.
0.056<p<0.112
p is kinda like our "best guess" answer, and we're giving it this range that it's probably within, for a certain level of confidence. You can see, that as the confidence goes down, that range can become bigger.

What is the measure of the exterior angle?The sum of the interior angle of a triangle is 180 degree.
The sum of angles on a straight line is 180 degrees.
From the diagram;
Angle 1 = 64 degreesAngle 2 = 75 degreesAngle 3 = ?First, we determine the third interior angle of the triangle.
Angle 1 + Angle 2 + Angle 3 = 180

139 + Angle 3 = 180
Angle 3 = 180 - 139
Angle 3 = 41 degrees
Now, angle 3 and the exterior angle forms a angle on a straight line.

In ΔQRS, s = 7.9 cm, ∠Q=125° and ∠R=23°. Find the length of q, to the nearest 10th of a centimeter.
The length of q, to the nearest 10th of a centimeter, is 8.8 cm.
We are given the following;
In ΔQRS, s = 7.9 cm, ∠Q=125° and ∠R=23°.
The third angle can be calculated using the angle sum property:
angle Q + angle R + angle S = 180 degrees
125 degrees + 23 degrees + angle S = 180 degrees
angle S = 180 - (125 + 23) degrees
angle S = 180 - 148 degrees
angle S = 32 degrees
To find the length of q we shall apply the Sine rule.
q / Sin Q = s / Sin S
q / Sin 125 = 7.9 / Sin 32
by cross multiplication we will get;
q = (7.9 x Sin 125) / Sin 32
q = (7.9 x 0.61) / 0.55
q = 8.8 cm (approximately)
So, the length of q is 8.8 cm.
Thus, the length of q, to the nearest 10th of a centimeter, is 8.8 cm.

If a > 0, the vertex is a minimum point.
In this question, the function is modeled as follows, considering x as the price divided by $2.
P(x) = -15x² + 60x + 30.
The coefficients are a = -15 < 0, b = 60, c = 30, therefore the x-value of the vertex is given by:
V = -b/2a

Kye's current credit card balance is $3,109.87 with a minimum payment of $159.00. Over the next month he spends $532.42. If the APR is 27.99% (billed monthly), what will Kye's new balance be, with interest?
Therefore , the solution of the given problem of interest comes out to be $4,088.14 is the new balance.
What exactly does interest mean?Divide the number by the expense of borrowing, the remaining time, and other factors to get the simple interest rate. In marketing, the straightforward return plan is principal interest payments plus hours. This technique is the simplest way to figure out interest. The most common way to determine income is as a percentage of the principal sum.
Here,
We must first figure out the interest on the present balance.
The interest rate is 27.99%/12, or 0.0233, per month.
As a result, the current balance's interest rate is:
=> 3,109.87 x 0.0233 = $72.43
When this interest is added to the outstanding amount, Kye's new balance is as follows:
=> 3,109.87 + 72.43 + 532.42 = $3,714.72
The minimum payment for the new amount must now be determined:
=> 3,714.72 x 0.02 = $74.29
Kye's minimum payment for the following month will be $159.00 because the minimum payment is the higher of $74.29 or that amount.
Kye's new balance with interest as a result of making the required minimum contribution and spending $532.42 is as follows:
=> 3,714.72 - 159.00 + 532.42 = $4,088.14.

4. y ⇒ ∞ as x ⇒ ∞ AND y ⇒ ∞ as x ⇒ -∞; Domain: (-∞, ∞); Range: [0, ∞)
Step-by-step explanation:
Rule for end behavior of polynomials:
(a) Positive leading coefficient, even degree: y ⇒ ∞ as x ⇒ ∞ AND y ⇒ ∞ as x ⇒ -∞
(b) Negative leading coefficient, even degree: y ⇒ -∞ as x ⇒ ∞ AND y ⇒ -∞ as x ⇒ -∞
(c) Positive leading coefficient, odd degree: y ⇒ ∞ as x ⇒ ∞ AND y ⇒ -∞ as x ⇒ -∞
(d) Negative leading coefficient, odd degree: y ⇒ -∞ as x ⇒ ∞ AND y ⇒ ∞ as x ⇒ -∞
Domain and range for a polynomial function with an odd degree will always be all real numbers, whether or not there's a constant or not.
Domain will always be all real numbers for a polynomial function with an even, whether or not there's a constant.
For a polynomial function with an even degree, the range will extend from the y-coordinate of the vertex to ∞, if the leading coefficient is positive
For a polynomial function with an even degree, the range will extend from -∞ to the y-coordinate of the vertex if the leading coefficient is negative.
