A 2.7 meter ladder leans against a house forming a 30° angle with the house. Exactly how far is the base of the ladder from the house?
Given the information, we have the following right triangle:
notice that x represents the distance from the base of the ladder to the house.
Then, using the trigonometric function sine we have the following:
[tex]\begin{gathered} \sin (30)=\frac{\text{opposite side}}{hypotenuse}=\frac{x}{2.7} \\ \Rightarrow\frac{1}{2}=\frac{x}{2.7} \\ \Rightarrow x=2.7\cdot\frac{1}{2}=1.35 \\ x=1.35 \end{gathered}[/tex]thus, the base of the ladder is 1.35m from the house

Kamal drew a scale drawing of a theater. He used the scale 6 inches = 10 feet. What scale factor does the drawing use?Simplify your answer and write it as a ratio, using a colon.
Given:
Kamal drew a scale drawing of a theater.
He used the scale 6 inches = 10 feet.
The scale factor will take the form:
[tex]inches\colon feet=x\colon y[/tex]Where (x) is the number of inches that corresponding to the number of feet (y)
So, x = 6, y = 10
So, the scale factor =

suppose that the amount of time it takes to build a highway varies directly with the length of the highway and inversely with the number of workers. suppose that it takes 100 workers 6 weeks to build 4 miles of Highway. how long will it take a 160 workers to build 16 miles of Highway?___weeks
Answer:
The amount of time it would take 160 workers to build 16 miles of Highway is;
[tex]15\text{ weeks}[/tex]Explanation:
Given that the amount of time it takes to build a highway varies directly with the length of the highway and inversely with the number of workers.
Let t represent the time in weeks, l represents the length of the highway in miles, and n represent the number of workers;
So, we have;
[tex]\begin{gathered} t\propto\frac{l}{n} \\ t=k\frac{l}{n} \\ k=\frac{nt}{l} \end{gathered}[/tex]Given;
it takes 100 workers 6 weeks to build 4 miles of Highway
[tex]\begin{gathered} n=100 \\ t=6 \\ l=4 \\ k=\frac{nt}{l} \\ k=\frac{100\times6}{4} \\ k=150 \end{gathered}[/tex]so, for 160 workers to build 16 miles of Highway the time it will take is;
[tex]\begin{gathered} n=160 \\ l=16 \\ k=150 \\ t=k\frac{l}{n} \\ t=150\times\frac{16}{160} \\ t=\frac{150}{10} \\ t=15 \end{gathered}[/tex]Therefore, the amount of time it would take 160 workers to build 16 miles of Highway is;

The length of the rectangle based on the information is 6/25 meters.
The length is 3/5 times more than the width.
How to calculate the length?From the information, the area of a rectangle is 3/5 square m² and the width is 2/5m. It should be noted that the length will be:
Length = Area / Width
Length = 3/5 ÷ 2/5
Length = 3/5 × 2/5
Length = 6/25
The length will s 6/25 meters.
The number of times that the length is more than the width will be:
= 6/25 ÷ 2/5
= 6/25 × 5/2
= 3/5 time.

Find an equation for the perpendicular bisector of the line segment whose endpoints are (1,4)and(-9,-6)
The endpoints are (1,4) and (-9,-6). The equation for the perpendicular bisector of the line segments with given end points is x-y+3=0.
Given that,
The endpoints are (1,4) and (-9,-6).
We have to find the equation of the perpendicular bisector of the line segments with given end points.
First we have to find
The slope of the line m= [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
m=(-6-4)/(-9-1)
m=-10/-10
m=1
Now,
The equation of the line is y-y₁=m(x-x₁)
Taking point (1,4)
y-4=1(x-1)
y-4=x-1
x-y+4-1=0
x-y+3=0
Therefore, the equation for the perpendicular bisector of the line segments with given end points is x-y+3=0.

In right triangle ABC, C is the right angle. Which of the following is cos B if sin A = 0.4
Answer:
Given that,
In right triangle ABC, C is the right angle.
sin A=0.4
To find cos B,
we get the triangle as,
we know that,
Hypotenuse of the triangle is AB
For the angle A, opposite side is CB
For the angle B, adjacent side is CB
From the definition of sine and cosine we get,

As per the question statement, a distribution of values is normal with a mean of 198 and a standard deviation of 74.5 and we are supposed to find P(10), which is the score separating the bottom 10% from the top 90%.
Given mean (µ) = 48.5 , SD(σ) = 18.2
z = (X - μ) / σ, where X = data
X = 216.74
z = (216.74 - 198) / 74.5 = 0.2515 or 25.15%

The general equation of a horizontal line is?
Solution
Explanation:
The equation of a horizontal line passing through a point (a, b) is y = b, where 'b' is constant because in the equation y = mx + b, where 'b' is the y-intercept, there is no change in the value of y on the horizontal line and the slope is zero, therefore, the equation of a horizontal line is y = b.
Answer:
The general equation of a horizontal line is y = b where b is constant.

What is the distance between two points?The distance between two points is defined as the length of the line segment between two places representing their distance.
Given AB with coordinates A(-4,5) and B(12,13).
The formula of the distance between two points is A(x₁, y₁) and B(x₂, y₂) is given by: d (A, B) = √ (x₂ – x₁)² + (y₂ – y₁) ².
x₁ = -4, y₁ = 5
x₂ = 12, y₂ = 13
distance = √ (12 – (-4))² + (13 – 5)²
distance = √ (12 + 4)² + (8)²
distance = √ (16)² + (8)²
distance = √ (256 + 64)
distance = √320
distance = 17.88 units
The horizontal distance is 16 units and the vertical distance is 8 units from A to B which are determined by the graphing method.
