Answer:
[tex]\theta = 4.8^\circ[/tex]
It is possible
Step-by-step explanation:
Given
See attachment for the construction
Solving (a): The minimum angle
This is calculated as thus:
[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
[tex]tan(\theta) = \frac{15}{180}[/tex]
[tex]tan(\theta) = 0.0833[/tex]
Calculate [tex]\theta[/tex]
[tex]\theta = tan^{-1}(0.0833)[/tex]
[tex]\theta = 4.761[/tex]
[tex]\theta = 4.8^\circ[/tex] --- approximated
Solving (b):
First; calculate the height of the building using the following equivalent ratio.
[tex]h : 420 = 15 : 180[/tex]
Where h is the height of the building
[tex]\frac{h }{ 420 }= \frac{15 }{ 180}[/tex]
[tex]h= \frac{15 }{ 180}*420[/tex]
[tex]h= \frac{15*420 }{ 180}[/tex]
[tex]h= \frac{6300}{ 180}[/tex]
[tex]h= 35[/tex]
This means that it is possible that the builder builds a 32 feet high building
From the picture attached,
Angle of depression = Angle of elevation (θ) [Alternate angles]
Apply tangent rule in ΔCDP,
[tex]\text{tan}\theta=\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
[tex]\text{tan}\theta=\frac{CD}{DP}[/tex]
[tex]=\frac{15}{180}[/tex]
[tex]=\frac{1}{12}[/tex]
[tex]\theta=\text{tan}^{-1}(0.08333)[/tex]
[tex]\theta=4.76^\circ[/tex]
Similarity of two triangles:If two triangles are similar, their corresponding sides will be proportional.Use this property to get the height of the new building.
Since, ΔABP and ΔCDP are the similar triangles, their corresponding sides will be proportional.
[tex]\frac{AB}{BP}=\frac{CD}{DP}[/tex]
[tex]\frac{AB}{420}=\frac{15}{180}[/tex]
AB = [tex]\frac{420\times 15}{180}[/tex]
= 35 feet
But the construction for a new building has a maximum height restriction of 32 feet.
And the height of the building is more than the restricted height.
Therefore, it is not possible for the builder to have a rooftop patio with a view of the ocean.

Answer:
X : ___ 0 ____ 1 _____ 2 _____ 3 _____ 4
P(x): _ 1/16 __ 1/4 ____ 3/8 ____ 1/4 ____ 1/16
Step-by-step explanation:
Given the listed possible occurrence of boys and girls :
B = boys ; G = girls
BBBB, BBBG, BBGB, BGBB, GBBB, BGBG, GBGB, BGGB, GBBG, BBGG, GGBB, BGGG, GBGG, GGBG, GGGB, and GGGG
Let x = distribution of girls
P = required outcome / Total possible outcomes
For :
x = 0 ;(BBBB) = 1
P(x) = 1/16
x = 1 ; (BBBG, BBGB, BGBB, GBBB) = 4
P(x) = 4 / 16 = 1/4
P(x = 2) ; (BGBG, GBGB, BGGB, GBBG, BBGG, GGBB) = 6
P(x) = 6 / 16 = 3/8
P(x = 3) ; (BGGG, GBGG, GGBG, GGGB) = 4
P(x) = 4 / 16 = 1/4
P(x = 4) ; (GGGG) = 1
P(x) = 1 / 16
X : ___ 0 ____ 1 _____ 2 _____ 3 _____ 4
P(x): _ 1/16 __ 1/4 ____ 3/8 ____ 1/4 ____ 1/16

Solve for a.
a+(−4)=−13
a=−17
a=−9
a = 9
a = 17
Answer:
a = -9
Step-by-step explanation:
a+(-4)=-13
add 4 to each side
a-4+4 = -13+4
a = -9
Answer:
a = - 9
Step-by-step explanation:
a + (-4) = -13
Add 4 to both sides
a + (-4) + 4 = -13 + 4
a + 0 = -9
a = -9

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Calculate the area of the trapezoid, which is not drawn to scale.
Answer:
38 in
Step-by-step explanation:
Ok, so the bottom part is a rectangle and the top part is a triangle. We’re gonna split those into two different shapes.
8 * 4 = 32, this is the area of the bottom rectangle.
To get the side length of the top triangle, we have to subtract 8 from 11.
11 - 8 = 3
(3 * 4)/2 = 6, this is the area of the top triangle.
Add the two areas, 32 + 6 = 38

A group of high school students are volunteering for Habitat for Humanity during their summer break. They
are putting the finishing touches on a house they built. Working alone, Kendra can paint a certain room in 7
hours. Joe can paint the same room in 6 hours. Write an equation that can be used to find how long it will
take them working together to paint the room. How many hours will it take them to paint the room? If
necessary, round your answer to the nearest tenth.
In response to the question, we may say that It will take Kendra and Joe expression approximately 3.2 hours to paint the room together.
what is expression ?An expression in mathematics is a collection of representations, numbers, and conglomerates that mimic a statistical correlation or regularity. A real number, a mutable, or a mix of the two can be used as an expression. Mathematical operators include addition, subtraction, fast spread, division, and exponentiation. Expressions are widely used in arithmetic, mathematics, and shape. They are employed in the depiction of mathematical formulas, the solving of equations, and the simplification of mathematical relationships.
Let's denote the time it takes Kendra to paint the room as "K" and the time it takes Joe to paint the room as "J". We can use the formula:
[tex]1/K + 1/J = 1/T\\1/7 + 1/6 = 1/T\\13/42 = 1/T\\13T = 42\\[/tex]
Therefore, T = 42/13 ≈ 3.2 hours (rounded to the nearest tenth).
It will take Kendra and Joe approximately 3.2 hours to paint the room together.

A new car loan has monthly payments of $482.75. How much money will be paid on the car loan after 3 years?
========================================================
Work Shown:
1 year = 12 months
3*(1 year) = 3*(12 months) ..... multiply both sides by 3
3 years = 36 months
You'll make 36 payments, each being $482.75, which means the total amount of money paid is 36*482.75 = 17,379 dollars
