Answer:

273 tiles

Step-by-step explanation:

Given

Square tile

[tex]Side=\frac{1}{2} ft[/tex]

Bathroom floor

[tex]Length = 10\frac{1}{2}ft[/tex]

[tex]Width = 6\frac{1}{2}ft[/tex]

Required

Determine the number of tiles to cover the floor

First, we calculate the area of the floor:

[tex]A_{floor} = Length * Width[/tex]

[tex]A_{floor} = 10\frac{1}{2} * 6\frac{1}{2}[/tex]

Convert to decimals

[tex]A_{floor} = 10.5 * 6.5[/tex]

[tex]A_{floor} = 68.25ft^2[/tex]

Next, we calculate the area of the square tile:

[tex]A_{tile} = Side * Side[/tex]

[tex]A_{tile} = \frac{1}{2} * \frac{1}{2}[/tex]

Convert to decimal

[tex]A_{tile} = 0.5 * 0.5[/tex]

[tex]A_{tile} = 0.25ft^2[/tex]

The number of tiles is then calculated as:

[tex]Tiles = \frac{A_{floor}}{A_{tile}}[/tex]

[tex]Tiles = \frac{68.25ft^2}{0.25ft^2}[/tex]

[tex]Tiles = \frac{68.25}{0.25}[/tex]

[tex]Tiles = 273[/tex]

Answer:

In Geometry, there are five fundamental angle pair relationships:

Complementary Angles.

Supplementary Angles.

Adjacent Angles.

Linear Pair.

Vertical Angles.

The measure of the angle u and angle t will be 29 degrees.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The angle u is congruent to angle t.

From the diagram, angle t, angle u, and angle 122 are supplementary angles. Then the equation is given as,

∠t + ∠u + 122° = 180°

∠t + ∠t  = 58°

2∠t = 58°

∠t = 29°

The measure of the angle u and angle t will be 29 degrees.

190 games

Step-by-step explanation:

²⁰C₂ = 20!/[(20 - 2)! * 2!] = 190

The number of games that should be there is 190 games.

Since in Ethiopia, there are 20 premier league soccer teams.

So here we used the combination

i.e.

= ²⁰C₂

= 20!/[(20 - 2)! * 2!]

= 190

A combination refers to the mathematical technique where it measures the no of possible arrangements where the selection order should not be considered. It can be selected in any sequence.

hence, we can conclude that The number of games that should be there is 190 games.

Answer:

[tex]\lambda=10000[/tex] miles

Step-by-step explanation:

We are given that

[tex]\beta=10000 miles[/tex]

Exponential distribution function

[tex]f(x)=\frac{1}{\beta}e^{-\frac{x}{\beta}}, x\geq 0[/tex]

             0, otherwise

Using the formula

[tex]f(x)=\frac{1}{10000}e^{-\frac{x}{10000}},x\geq0[/tex]

              0, otherwise

[tex]E(x)=\int_{-\infty}^{\infty}xf(x) dx[/tex]

Using the formula

[tex]\lambda=E(x)=\frac{1}{10000}\int_{0}^{\infty}xe^{-\frac{x}{10000}}dx[/tex]

[tex]\lambda=\frac{1}{10000}([-10000xe^{-\frac{x}{10000}}]^{\infty}_{0}+10000[-10000e^{-\frac{x}{10000}}]^{\infty}_{0})[/tex]

Using formula

[tex]\int u\cdot vdx=u\int vdx-\int (\frac{du}{dx}\int vdx)dx[/tex]

[tex]\lambda=\frac{1}{10000}(0-(10000)^2(0-1))=10000[/tex]

Hence, the value of [tex]\lambda=10000[/tex] miles

Answer:

The value of k is -4 and the equation of the line is [tex]y =-\frac{1}{2}\cdot x +10[/tex].

Step-by-step explanation:

The equation of the line is defined by the following formula:

[tex]y = m\cdot x + b[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]b[/tex] - y-Intercept.

[tex]m[/tex] - Slope.

In addition, the slope of the equation of the line ([tex]m[/tex]) can be known from two distinct points:

[tex]m = \frac{y-y_{o}}{x-x_{o}}[/tex] (2)

Where [tex]x_{o}[/tex] and [tex]y_{o}[/tex] are the coordinates of the reference point.

By applying (2) in (1), we derive the resulting expression:

[tex]y = \frac{y-y_{o}}{x-x_{o}}\cdot x + b[/tex]

[tex]y\cdot (x-x_{o}) = (y-y_{o})\cdot x + b\cdot (x-x_{o})[/tex]

[tex]x\cdot y -y\cdot x_{o} = x\cdot y -x\cdot y_{o}+b\cdot x -b\cdot x_{o}[/tex]

[tex](b-y)\cdot x_{o} = b\cdot x -x\cdot y_{o}[/tex]

[tex](b-y)\cdot x_{o} +x\cdot y_{o} = b\cdot x[/tex] (3)

If we know that [tex]b = 10[/tex], [tex]x = 2[/tex], [tex]y = 9[/tex], [tex]x_{o} = k+10[/tex] and [tex]y_{o} = -2\cdot k -1[/tex], then the value of [tex]k[/tex] is:

[tex](10-9)\cdot (k+10)+2\cdot (-2\cdot k -1) = (10)\cdot (2)[/tex]

[tex]k+10 -4\cdot k -2 = 20[/tex]

[tex]-3\cdot k +8 = 20[/tex]

[tex]-3\cdot k = 12[/tex]

[tex]k = -4[/tex]

The value of the slope is:

[tex]m = \frac{9-7}{2-6}[/tex]

[tex]m = -\frac{1}{2}[/tex]

The equation of the line is [tex]y =-\frac{1}{2}\cdot x +10[/tex].
