a floor that is 15 15 feet by 12 feet is being covered by tiles that are 1.5 feet by 1.5 feet. which is the best represents the number of tiles that will be needed
Answers
The best representation of the number of tiles that will be needed to cover the Floor is 80 tiles.
The number of tiles needed to cover the floor, we can calculate the total area of the floor and divide it by the area of each tile.
The area of the floor is given by the product of its length and width: 15 feet * 12 feet = 180 square feet.
The area of each tile is given by the product of its length and width: 1.5 feet * 1.5 feet = 2.25 square feet.
To find the number of tiles needed, we divide the total area of the floor by the area of each tile:
Number of tiles = (Total area of the floor) / (Area of each tile) = 180 square feet / 2.25 square feet = 80 tiles.
therefore, the best representation of the number of tiles that will be needed to cover the floor is 80 tiles.

The perimeter of an isosceles triangle is 45 inches. Two sides of the triangle are congruent,
and the third side is twice as long as the sum of the congruent sides. What is the length of the
third side of the triangle in inches?
Answers
Answer:
Length of third side = 30 inches
Step-by-step explanation:
We will need a system of equations to find the length of the third side.
First equation:
Let x represent the length of just one of the congruent sides and let y represent the length of the third side.We know the perimeter of a triangle is simply the sum of its sides.
Thus, since the perimeter is 45, our first equation is x + x + y = 45, which simplifies to 2x + y = 45.
Second equation:
Since we're told that the length of the third side is twice as long as the sum of the congruent sides, our second equation is y = 2(x + x), which simplifies to y = 2(2x) and then finally y = 4x
Method: Substitution.
We can first solve for x (length of one of the congruent sides) by substituting y = 4x for y in 2x + y = 45:
2x + 4x = 45
6x = 45
x = 7.5
Find y:
Now we can find y (length of the third side) by plugging in 7.5 for x in y = 4x:
y = 4(7.5)
y = 30
Thus, the length of the third side is 30 inches.
Optional Step to check validity of answers.
First equation: Check that the sum of 7.5, 7.5, and 30 = 45
7.5 + 7.5 + 30 = 45
15 + 30 = 45
45 = 45
Second equation: Check that 30 is twice the sum of 7.5 + 7.5
30 = 2(7.5 + 7.5)
30 = 2(15)
30 = 30
Thus, our answers are correct and we've correctly determined the length of the third side of the triangle in inches.

The regression equation is: y = -0.0068824x + 36.8881
So, the correct option is:
D) None of these.
To compute the regression equation based on the given data, we can use the formulas for slope (b1) and y-intercept (bo):
b1 = (NΣXY - ΣXΣY) / [tex](N\sum X^2 - (\sum X)^2)[/tex]
bo = (ΣY - b1ΣX) / N
Where:
N = Number of data points (in this case, 11)
ΣX = Sum of all X values (prices)
ΣY = Sum of all Y values (average number of pounds sold per day)
ΣXY = Sum of the product of X and Y values
[tex]\sum X^2[/tex] = Sum of the squares of X values
Using the provided data:
Ex = 210
Xy = 450
Zcy = 10387
Zz = 7275
Xy = 42471
Let's calculate the required values:
N = 11
ΣX = Ex + Zcy + Zz = 210 + 10387 + 7275 = 17872
ΣY = Xy = 450
ΣXY = Xy = 450
[tex]\sum X^2 = (Ex)^2 + (Zcy)^2 + (Zz)^2 = (210)^2 + (10387)^2 + (7275)^2 = 239208144[/tex]
Now, substitute these values into the formulas to find b1 and bo:
[tex]b1 = (11 \times450 - 17872 \times 450) / (11 \times239208144 - (17872)^2)[/tex]
= -14112250 / 2050445128
≈ -0.0068824
bo = (450 - (-0.0068824 [tex]\times[/tex] 17872)) / 11
= (450 + 122.7790368) / 11

The values of the variables are y = 102° and z = 23°.
Given that are two parallel lines j and m we need to find the measures of the variables y and z,
So,
Since, j║m, therefore, y and 78° are supplementary because they are exterior consecutive angles between two parallel lines,
So,
y + 78° = 180°
y = 180° - 78°
y = 102°
Now,
y and (4z-14) are linear pair angles, which means they are also supplementary.
Therefore,
y + (4z-14) = 180°
102° + 4z - 14 = 180°
4z + 88 = 180°
4z = 92°
z = 23°
Hence the values of the variables are y = 102° and z = 23°.

The given line is in the form Ax + By = C, where A = 3, B = 2, and C = -1. To find the slope of this line, we can rearrange the equation in slope-intercept form (y = mx + b), where m is the slope:
3x + 2y = -1
2y = -3x - 1
y = (-3/2)x - 1/2
The slope of the given line is -3/2. Since a line perpendicular to this line will have a negative reciprocal slope, we can find the perpendicular slope by taking the negative reciprocal of -3/2:
Perpendicular slope = -1 / (-3/2) = 2/3
Now we have the slope of the perpendicular line, and we can use the point-slope form of a line (y - y₁ = m(x - x₁)) to find its equation. Plugging in the values (5, 3) for (x₁, y₁) and 2/3 for m:
y - 3 = (2/3)(x - 5)
Expanding and simplifying:
3y - 9 = 2x - 10
2x - 3y = 1
Therefore, the equation of the line that is perpendicular to 3x + 2y = -1 and passes through the point (5, 3) is 2x - 3y = 1.
To find the equation of a line parallel to the given line and passing through the point (5, 3), we can use the same method. Since parallel lines have the same slope, the slope of the parallel line will also be -3/2.
Using the point-slope form with (5, 3) and -3/2:
y - 3 = (-3/2)(x - 5)
Expanding and simplifying:
2y - 6 = -3x + 15
3x + 2y = 21
Therefore, the equation of the line that is parallel to 3x + 2y = -1 and passes through the point (5, 3) is 3x + 2y = 21.

Answers
The required reverse Euclidean algorithm is the solution to the modular equation (5x) mod 91 is
x = 6(mod 91).
Given that (5*x) mod 91 =32.
To solve the modular equation (5*x) mod 91 =32 using reverse Euclidean algorithm is to find the modular inverse of 5 modulo 91.
Consider (5*x) mod 91 =32.
5x = 32(mod 91)
Apply the Euclidean algorithm to find GCD of 5 and 91 is
91 = 18 * 5 + 1.
Rewrite it in congruence form,
1 = 91 - 18 *5
On simplifying the equation,
1 = 91 (mod 5)
The modular inverse of 5 modulo 91 is 18.
Multiply equation by 18 on both sides,
90x = 576 (mod91)
To obtain the smallest positive solution,
91:576 = 6 (mod 91)
Divide both sides by the coefficient of x:
x = 6 * 90^(-1).
Apply the Euclidean algorithm,
91 = 1*90 + 1.
Simplify the equation,
1 + 1 mod (90)
The modular inverse of 90 modulo 91 is 1.
Substitute the modular inverse in the given question gives,
x = 6*1(mod 91)
x= 6 (mod91)
Therefore, the solution to the modular equation (5x) mod 91 is
x = 6(mod 91).

What change in volume results if 60.0 mL of gas is cooled from 33.0°C to 5.00°C
Answers
Answer:
The change in volume is -5.5 mL (a decrease in volume of 5.5 mL) when 60.0 mL of gas is cooled from 33.0°C to 5.00°C.
Step-by-step explanation:
To calculate the change in volume, we need to use the ideal gas law equation:
V1/T1 = V2/T2
where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature.
Given:
V1 = 60.0 mL
T1 = 33.0°C = 33.0 + 273.15 = 306.15 K
T2 = 5.00°C = 5.00 + 273.15 = 278.15 K
Now we can calculate V2, the final volume:
V1/T1 = V2/T2
(60.0 mL) / (306.15 K) = V2 / (278.15 K)
Cross-multiplying and solving for V2:
V2 = (60.0 mL) * (278.15 K) / (306.15 K)
V2 = 54.5 mL
The final volume, V2, is 54.5 mL.
To find the change in volume, we subtract the initial volume from the final volume:
Change in volume = V2 - V1
Change in volume = 54.5 mL - 60.0 mL
Change in volume = -5.5 mL
Therefore, the change in volume is -5.5 mL (a decrease in volume of 5.5 mL) when 60.0 mL of gas is cooled from 33.0°C to 5.00°C.

To determine the radius of each wheel, we can use the formula for the circumference of a circle:
Circumference = 2πr,
where "Circumference" represents the circumference of the wheel and "r" represents the radius of the wheel.
Given that the circumference of each wheel is 22 inches, we can set up the equation as follows:
22 = 2πr.
To solve for the radius, we'll isolate "r" by dividing both sides of the equation by 2π:
22 / (2π) = r.
Using a calculator for the approximation, we get:
r ≈ 3.5 inches.

Step-by-step explanation:
let's compare each equations to equation of a line
which is y=mx+c
first equation
6x - 2y = -4
-2y = -6x -4
divide through by -2
y=3x+2
second equation
3x-y= -2
-y= -3x-2
divide through by -1
y= 3x+2
since the slope and intercept of the first and second equation equal each other then the number of solutions is infinitely many.
note that m is slope and c is intercept.
There are books on a shelf. of these books are new. The rest of them are used. what is the ratio of used books to all books on the shelf?
Answers
Let's denote the total number of books on the shelf as 'total_books', and the number of new books as 'new_books'.
The number of used books can be calculated as the difference between the total number of books and the number of new books:
used_books = total_books - new_books
To find the ratio of used books to all books on the shelf, we divide the number of used books by the total number of books:
Ratio of used books to all books = used_books / total_books
Substituting the expression for used_books, we have:
Ratio of used books to all books = (total_books - new_books) / total_books
Simplifying further:
Ratio of used books to all books = 1 - (new_books / total_books)
Therefore, the ratio of used books to all books on the shelf is equal to 1 minus the ratio of new books to total books.
