A rectangular bathroom floor is covered with square tiles that are 1 1/2 feet by 1 1/2 feet. The length of the bathroom floor is
kenny6666 [7]

Answer:

The number of square tiles required to cover the bathroom floor is approximately 31.

Step-by-step explanation:

The dimensions of the rectangular floor of the bathroom are:

Length = 10.5 ft.

Breadth = 6.5 ft.

The dimensions of the square tiles are:

Side = 1.5 ft.

The area of the rectangular floor of the bathroom is:

Area\ of Bathroom\ floor=Length\times Breadth\\=10.5\times6.5\\=68.25

The area of 1 square tile:

Area\ of\ 1\ square\ tile=(SIde)^{2}\\=(1.5)^{2}\\=2.25

The number of tiles required to cover the bathroom floor is:

Number\ of\ tiles=\frac{Area\ of\ bathroom\ floor}{Area\ of\ 1\ square\ tile} \\=\frac{68.25}{2.25}\\ =30.3333\\\approx31

Thus, the number of square tiles required to cover the bathroom floor is approximately 31.

Write an equation for the perpendicular bisector of the line segment joining the two points.
Leona [35]
Points (1, 7)  and  (-3, 2)

Slope for a line between (x₁, y₁) and (x₂, y₂) , m = (y₂ -y₁) / (x₂- x₁)

The slope for the line joining the two points =  (2 - 7) / (-3 - 1) = -5/-4

Slope = 5/4

Hence the perpendicular bisector would have a slope of -1/(5/4) = -4/5

By condition of perpendicularity

For points (1, 7)  and  (-3, 2),

Formula for midpoints for (x₁, y₁) and (x₂, y₂) is ((x₁ +x₂)/2 , (y₁+ y₂)/2)

Midpoint for (1, 7)  and  (-3, 2) = ((1+ -3)/2 , (7+2)/2) = (-2/2, 9/2)

= (-1, 9/2)

Since the slope of perpendicular bisector is -4/5 and passes through the midpoint (-1, 9/2)

Equation  y - y₁ = m (x - x₁)

                y - 9/2 = (-4/5) (x - -1)
           
                y - 9/2 = (-4/5)(x + 1)

               5(y - 9/2) = -4(x + 1)

               5y - 45/2 = -4x - 4

                 5y =  -4x - 4 + 45/2
           
                5y + 4x = 45/2 - 4

                  5y + 4x = 22  1/2  - 4 =  18 1/2

                  5y + 4x =  37/2

                  10y + 8x = 37

The equation of the line to perpendicular bisector is 10y + 8x = 37

Simplify and determine the coefficient of (-2/5)(-x)(5y)(-2x).
suter [353]
When multiplying an odd number of factors,, then that means they will equal a negative. This rule will make this expression change to the following:
-\frac{2}{5}x × 5y × 2x
Now reduce the numbers with 5
-2xy × 2x
Lastly,, calculate the product to get your final answer
-4x²y
This means that your coefficient is -4 and the simplified version of your expression is -4x²y.

A guy wire connects the top of a 18 3/4 foot tall tornado siren to the ground where Samson's shadow ends. The distance from the
Dafna1 [17]

Answer:

40 feet

Step-by-step explanation:

Required:

Find the length of Samson's shadow

The question can be illustrated with the attached figure where Samson's shadow is represented with x.

To solve for x, we make use of the following equivalent ratios:

18.75 : 120 = 6.25 : x

Convert to fraction

\frac{18.75}{120} = \frac{6.25}{x}

Cross Multiply

18.75 * x = 120 * 6.25

18.75 * x = 750

Make x the subject

x =\frac{750}{18.75}

x =40

<em>Hence, Samson's shadow is 40ft</em>
