Step-by-step explanation:
Two squares with the same side lengths will always be a scale copy. Every side is equal because all sides are the same length if it wasn't that way it would be a rectangle or trapezoid.
A rectangle whose all sides are equal is called a square. The two squares with the same length side will be lengths scaled copies of one another.
What is a square?A rectangle whose all sides are equal is called a square.
A square is always a rectangle, parallelogram, and a quadrilateral but its reverse statement may or may not be true.(ie it is not always necessary that a rectangle is a square or a parallelogram is a square).
As it is known that two squares are always similar to each other which is because all the angles of a square are always 90°. Therefore, any two squares are always similar to each other.
Now, as it is given that the two square have the same length sides. Therefore, the two squares with the same length side will be lengths scaled copies of one another. This is because all the sides are equal and all the angles are equal.
Hence, the two squares with the same length side will be lengths scaled copies of one another.

A visitor guide for a downtown area lists many restaurants. Which of the following is an example of a quantitative variable the guide could report for each restaurant? A. the zip code of the restaurant B. the number of seats in the restaurant C. the type of cuisine the restaurant offers D. a restaurant critic’s letter grade (A–F)
The correct answer is B. The number of seats in the restaurant
Explanation:
The number of seats is a quantitative variable because this is expressed using numbers and can be understood through numbers. For example, the average of seats in the restaurants in the area can be calculated by finding the total of seats and dividing the number into the number of restaurants.
On the other hand, the type of cuisine and the restaurant critic's letter grade do not involve numbers but qualities, which make them qualitative variables. Also, even if zip codes are expressed using numbers these cannot be understood through them, for example, you cannot add two zip codes.

Answer: is B
Step-by-step explanation:
-20, xmax
The most appropriate viewing window for determining the domain and range of the function is Xmin: –20, Xmax: 20Ymin: –20, Ymax: 20.
The given function is f(x)=-|x+5|+12.
We need to find the most appropriate viewing window for determining the domain and range of the function.
What is the domain and range of the function?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: (-∞, ∞), {x|x∈R}
Range: (-∞, 12], {y|y≤12}
So,window=Xmin: –20, Xmax: 20Ymin: –20, Ymax: 20
Therefore, the most appropriate viewing window for determining the domain and range of the function is Xmin: –20, Xmax: 20Ymin: –20, Ymax: 20.

Answer:
1) [tex](4x)(x+2)-x(3x+5)[/tex]
2A) [tex]w^2+3w[/tex]
2B) [tex]28\text{ in}^2[/tex]
Step-by-step explanation:
1)
First, let's write the expressions for the area of the entire shaded region and the white area.
The formula for the area of a rectangle is given by:
[tex]A=lw[/tex]
For the entire shaded rectangle, the length is (4x) and the width is (x+2). So, the area is:
[tex](4x)(x+2)[/tex]
For the white rectangle, the length is (3x+5) and the width is (x). So, the area is:
[tex]x(3x+5)[/tex]
The shaded area is the entire shaded rectangle minus the area of the white rectangle. Therefore, our expression would be:
[tex](4x)(x+2)-x(3x+5)[/tex]
2)
Part A)
So, we are given that the length of the rectangle is 3 inches greater than the width.
The area of a rectangle is given by:
[tex]A=lw[/tex]
So, let w be width and let l be the length.
Since the length is 3 inches greater than the width, this means that the l is (w+3).
Thus, substitute. Our expression will therefore be:
[tex]lw\\w(w+3)[/tex]
Since we want a polynomial, let's expand:
[tex]=w^2+3w[/tex]
Part B)
To find the area when the width is 4, substitute 4 for w:
[tex]w^2+3w\\=(4)^2+3(4)[/tex]
Square and multiply:
[tex]=16+12[/tex]
Add:
[tex]=28\text{ in}^2[/tex]
So the area is 28 square inches.

Complete Question
Assume the random variable x is normally distributed with mean u=87 and standard deviation o=5. Find the indicated probability.
P(x<81)
P(x<81)=__(Round to four decimal places).
Answer:
The value is [tex]P(x < 81) = 0.11507[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 87[/tex]
The standard deviation is [tex]\sigma = 5[/tex]
The probability is mathematically represented as
[tex]P(x < 81) = P (\frac{X - \mu }{\sigma } < \frac{81 - 87 }{5 } )[/tex]
Generally [tex]\frac{X - \mu}{\sigma} = Z (The \ z-score \ of X )[/tex]
[tex]P(x < 81) = P (Z < - 1.2)[/tex]
From the z-table
[tex]P (Z < - 1.2) = 0.11507[/tex]
So [tex]P(x < 81) = 0.11507[/tex]

The size of a playground is 160 feet by 360
feet. A model is created that measures 4
inches by 9 inches.
Unit Rates
Answer:
The playground is 160ft by 360ft.
The model is 4in by 9in
First, 1ft = 12 inches.
Then the measures of the playground, in inches, is:
160*12in = 1920 in
360*12in = 4320in
The playground is 1920in by 4320in.
Then, the ratios between the measures of the playground and the model are:
1920in/4in = 480
4320in/9in = 480
This means that each inch in the model, represents 480 inches in the actual playground.

(a) PQ=(Round to the nearest tenth as needed.)
Answer/Step-by-step explanation:
Given:
P(2, 6)
Q(-6, 1)
Required:
a. PQ
b. Coordinate of the midpoint of PQ
SOLUTION:
a. [tex] PQ = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] P(2, 6) = (x_1, y_1) [/tex]
[tex] Q(-6, 1) = (x_2, y_2) [/tex]
[tex] PQ = \sqrt{(-6 - 2)^2 + (1 - 6)^2} [/tex]

[tex] PQ = \sqrt{89} = 3.1 [/tex] (to nearest tenth)
b. Coordinate of the midpoint of PQ
[tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]
Let [tex] P(2, 6) = (x_1, y_1) [/tex]
[tex] Q(-6, 1) = (x_2, y_2) [/tex]
Thus:
[tex] M(\frac{2 +(-6)}{2}, \frac{6 + 1}{2}) [/tex]
[tex] M(\frac{-4}{2}, \frac{7}{2}) [/tex]
[tex] M(-2, \frac{7}{2}) [/tex]
The coordinates of the midpoint of PQ are (-2,3.5) and this can be determined by using the midpoint formula.

The equation that could be used to determine the time, t, it takes to run 10,000 meters as a function of the average speed, s, of the runner where t is in minutes and s in miles per minute is t = 6.2/s miles/minute
What is an average speed?Average speed is defined as the rate of change in distance of a body. Mathematically;
Speed = Distance/TimeGiven the distance of the runner in miles to be;
d = 6.2milesTime taken = tAverage speed = sTo express t in terms of the average speed s and distance of 6.2miles, we will substitute the values into the formula;
s = D/tSubstituting D = 6.2miles into the formula;
s = 6.2/tCross multiply
St = 6.2Divide both sides by 's'

1) A swimming pool currently has 1,500 gallons of water in it and is filling at a rate of two gallons per hour. How many gallons will the pool hold in eight hours?
Answer:
1516 Gallons
Step-by-step explanation:
For this problem, we will simply take the initial amount of water, 1500 gallons, and add the extra water after eight hours.
So if the pool is filling at a rate of 2 gallons per hour, and 8 hours pass by, then the pool will have filled an additional 16 gallons. (2 * 8 = 16).
Then, we add the initial amount of 1500 gallons to the additional 16 gallons to get the amount of water in the pool after 8 hours.
The total the pool is holding is 1516 gallons after 8 hours.
Cheers.
