The minimum number of tiles will be 122 that Imane needs to cover the floor.
How to Convert Square Feet to Square Inches?Multiply the area by the conversion ratio to convert a square foot measurement to a square inch measurement. Because one square foot equals 144 square inches, you may use the following easy formula to convert:
square inches = square feet × 144
The area in square inches is equal to the square feet multiplied by 144.
The floor she wants to cover has an area of 216 square feet.
The required area in square inches is :
216 × 144 = 31,104 sq in
Each tile covers an area of 256 square inches.
The minimum number of tiles = 31,104 sq in / 256 sq in
The minimum number of tiles = 121.5 ≈ 122
Thus, the minimum number of tiles will be 122 that Imane needs to cover the floor.

Any movement of the graph either horizontally or vertically parallel to the -axis is referred to as a translation.
In mathematics, a translation is the movement of a shape left, right, up, or down. The translated shapes are identical to the original ones in size, indicating that they are congruent. They simply changed positions in one or more directions. The shape is unchanged because it is simply being transferred from one location to another.

The temperature of a cooling liquid is given by the function T(m) = 38 (0.82)" +21, where T represents the temperature in degrees Celsius and m represents the number of minutes, m≥0, that the liquid has been cooling. Which of the following represents a temperature that the liquid does not reach as it cools down?
(1) 53
(2) 16
(3) 41
(4) 28
Answers
Answer:
(2) 16°C
Step-by-step explanation:
[tex]T(m)=38(0.82)^m+21[/tex]
Find the temperature at the outset ([tex]m=0[/tex]):
[tex]T(0)=38(0.82)^0+21[/tex]
[tex]T(0)=38(1)+21[/tex]
[tex]T(0)=38+21[/tex]
[tex]T(0)=59[/tex]
Since the liquid is cooling, all temperatures equal to or less than 59°C are valid possibilities. However, over time (represented as [tex]m\rightarrow\infty[/tex]), [tex](0.82)^m[/tex] is reduced towards zero and, as such, [tex]38(0.82)^m[/tex] will be reduced towards zero. All that will remain is [tex]T(m)=21[/tex], which makes it the horizontal asymptote. This is shown in the attached graph.
Therefore, since 16°C falls below the asymptote, it does not represent a temperature that the liquid reaches as it cools down.

Answers
Solution:
Matthew and Benjamin start from the same spot and drives in opposite directions.
Given:
[tex]\begin{gathered} \text{Matthew's sp}eed=54mph \\ \text{Benjamin's sp}eed=47mph \\ \text{Distance apart after time (t)=1272.6miles} \end{gathered}[/tex]The formula for speed is given by;

Let the time both used be represented by t
Let Matthew's distance be represented by m
Let Benjamin's distance be represented by b
Thus,
Matthew's distance is calculated below;
[tex]\begin{gathered} \text{distance}=\text{speed}\times time \\ m=54\times t \\ m=54t \end{gathered}[/tex]Benjamin's distance is calculated below;
[tex]\begin{gathered} \text{distance}=\text{speed}\times time \\ b=47\times t \\ b=47t \end{gathered}[/tex]The distance covered by the two of them in opposite directions is their distance apart from the starting point.
Hence,

What equation represents the line that passes through the point (4, -5) and is perpendicular to the line x + 2y = 5?
Answers
The line that passes through the point (4, -5) and is perpendicular to the line x + 2y = 5? is y = 2x - 13.
Calculation:-
The equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is y = 2x - 13.
To determine if a point is on a line you can simply substitute the x and y coordinates into the equation. Another way to solve the problem would be to graph the line and see if it falls on the line. Plugging in will give which is a true statement, so it is on the line. Only one line can pass through a single point.

A line passes through the point (4, 8) and has a slope of 3/2.
Write an equation in slope-intercept form for this line.
Answers
Answer:
y=1.5x+2
Step-by-step explanation:
The equation for a line in slope-intercept form is written as y=mx+c where m is the slope and cis the y-intercept.
We know the slope is 3/2 or 1.5, so we can write
y=1.5x+c
We know the line contains the point (4,8), so we can sub this in to find c:
8=1.5(4)+c
8=6+c
c=2
Having found m and c, we can write the equation:
y=1.5x+2
Answer: [tex]\text{y}=\frac{3}{2}\text{x}+2\\\\[/tex]
This is the same as writing y = (3/2)x + 2
=====================================================
Work Shown:
[tex]\text{y}-\text{y}_1=\text{m}\left(\text{x}-\text{x}_1\right)\\\\\text{y}-8=\frac{3}{2}\left(\text{x}-4\right)\\\\\text{y}-8=\frac{3}{2}\text{x}+\frac{3}{2}(-4)\\\\\text{y}-8=\frac{3}{2}\text{x}-6\\\\\text{y}=\frac{3}{2}\text{x}-6+8\\\\\text{y}=\frac{3}{2}\text{x}+2\\\\[/tex]
I used point-slope form as the first step. The 'm' is the slope, and [tex](x_1,y_1) = (4,8)[/tex] is the point on the line.
The final step shows us the line has a y intercept of b = 2, which is at the location (0,2).
To graph this, draw a straight line through (0,2) and (4,8)
--------------
Check:
Plug x = 4 into the equation we found. We should arrive at y = 8.
[tex]\text{y}=\frac{3}{2}\text{x}+2\\\\\text{y}=\frac{3}{2}*4+2\\\\\text{y}=\frac{12}{2}+2\\\\\text{y}=6+2\\\\\text{y}=8\\\\[/tex]
This confirms (4,8) is indeed on this line and confirms the answer is correct.
You can also use graphing tools like Desmos or GeoGebra to quickly and visually confirm the answer.

What is height difference?
Given that length and height refer to a shape's length and height, respectively, respectively, there is a very clear distinction between the two. In a plane, length is the measure that is horizontal, whereas height is the measure that is vertical. Length, breadth, and height are crucial geometrical dimensions used to describe shapes.
A person's inherited genetic makeup accounts for about 80% of the normal variation in height, with the remaining 20% of the height difference coming from environmental factors like diet and upbringing.

The perimeter and the area of the ground are 101.5 m and 620.125 m², respectively.
We have a ground. The shape of the ground is a rectangle. The length and breadth of the rectangular ground are 30.25 m and 20.5 m, respectively. We need to find the perimeter and the area of the rectangular ground.
Let the perimeter and the area of the ground be denoted by the variables "P" and "A", respectively. The formulas for the perimeter and area of a rectangle are used below.
P = 2×(L + B)
P = 2×(30.25 + 20.5)
P = 2×50.75
P = 101.5
Hence, the perimeter of the rectangular ground is 101.5 meters.

After lunch, she arranged 12 small arrangements and 1 large arrangement, which took 67 minutes. How long does it take to assemble each type?
Answers
To solve this, we need to write a system of equations.
We know that it took her 62 minutes to assemble 11 small and 1 large.
Let's call the small arrangements S, and the large L.
Then:
[tex]11S+L=62[/tex]After lunch, she did 12 small and 1 large in 67 minutes. Then:
[tex]12S+L=67[/tex]Now we have the system of equations:
[tex]\begin{cases}11S+L=62 \\ 12S+L=67\end{cases}[/tex]To solve by elimination, we need to eliminate one unknown by adding or substracting the two equations. If we rest the first equation to the second equation:
[tex](12S+L)-(11S+L)=67-62[/tex]Now we can solve:
[tex]\begin{gathered} 12S-11S+L-L=65-62 \\ S=5 \end{gathered}[/tex]To make a small arrangement takes her 5 minutes. Now we can go back to the first equation and replace S = 5:

Answers
Step-by-step explanation:
I guess you are trying to find x value
slope equation:
slope, m = (y2-y1)/(x2-x1)
3/2 = (7-4)/(x-0)
3/2=3/x
1.5 = 3/x
1.5x = 3
x = 3/ 1.5
x = 2
