4(-4x-1)+x+3=44
Answer:
x = -3
Step-by-step explanation:
Start by distributing the 4 to the terms in the parentheses:
4(-4x)+4(-1)+x+3=44
-16x-4+x+3=44
Combine like terms
-15x-1=44
Add 1 to both sides
-15x-1+1=44+1
-15x=45
Divide both sides by -15
x = -3
Answer: x = -3
Step-by-step explanation: distribute, combine, divide, you get x = -3

A cone-shaped tent has a diameter of 12 ft and a height of 6 ft. What is the approximate volume of the tent? Use 3. 14 to approximate pi, and express your final answer as a decimal. Enter your answer as a decimal in the box. Ft³.
Answer:
226.08 ft³
Step-by-step explanation:
[tex]\textsf{volume of a cone}=\frac{1}{3}\pi r^2h[/tex]
(where [tex]r[/tex] = radius of the base and [tex]h[/tex] = height)
[tex]\textsf{radius}\ r=\frac{1}{2}\ \textsf{diameter}[/tex]
Given:
diameter = 12ft ⇒ radius = 12 ÷ 2 = 6 ftheight = 6ft[tex]\pi[/tex] ≈ 3.14[tex]\implies \textsf{volume of tent}=\frac{1}{3}\times3.14 \times 6^2 \times 6=226.08 \ \textsf{ft}^3[/tex]
A boat is heading towards a lighthouse, whose beacon-light is 105 feet above the water. From point AA, the boat’s crew measures the angle of elevation to the beacon, 7^{\circ}
∘
, before they draw closer. They measure the angle of elevation a second time from point BB at some later time to be 21^{\circ}
∘
. Find the distance from point AA to point BB. Round your answer to the nearest tenth of a foot if necessary.
Answer:
AB ≈ 581.6 ft
Step-by-step explanation:
The triangle from point A to the base of the lighthouse to the light beam can be modeled as a right triangle with the side opposite the angle being given. That means the distance from A to the base of the lighthouse is found from the tangent relation:
Tan = Opposite/Adjacent
tan(7°) = (105 ft)/A
A = (105 ft)/tan(7°)
Using similar reasoning, the distance to B is ...
B = (105 ft)/tan(21°)
Then the distance from A to B is ...
AB = (105 ft)/tan(7°) -(105 ft)/(tan(21°)) = (105 ft)(1/tan(7°) -1/tan(21°))
AB ≈ 581.6 ft
_____
Additional comment
We know that 1/tan(7°) = cot(7°) = tan(83°). This means the relation can be written ...
AB = (105 ft)(tan(83°) -tan(69°))

A father is 3 times as old as his son, 9 years ago the father was 4 times as old
as his son. find their present ages.
[tex]\bold{\huge{\green{\underline{ Solution }}}}[/tex]
Given :-We have given in the question that, A father is 3 times as old as his son 9 years a ago, The father was 4 times as old as his son To Find :-We have to find the present ages of son and father Let's Begin :-Let the present age of son be x
A father is 3 times old as his sonTherefore,
Present age of the father will be
[tex]\bold{ = 3x\:\: years }[/tex]
9 years ago,
The age of the son was
[tex]\bold{ = ( x - 9)\: years}[/tex]
So,Age of the father was
[tex]\bold{ = 3(x - 9) \:years ...eq(1)}[/tex]
But,
It is given that, 9 years a ago father was 4 times as old his son age That is, [tex]\bold{ 4(x - 9) ...eq(2)}[/tex]From eq(1) and eq(2) :-
[tex]\sf{3(x - 9) = 4(x - 9)}[/tex]
[tex]\sf{3x - 27 = 4x - 36}[/tex]
[tex]\sf{3x - 4x = -36 + 27}[/tex]
[tex]\sf{-x = -9 }[/tex]
[tex]\bold{\pink{ x = 9 \: years }}[/tex]
Thus, The present age of the son is 9 years
Therefore,Age of the father will be
[tex]\sf{ = 3 × 9 }[/tex]
[tex]\bold{\red{ = 27 \: years }}[/tex]
Hence, The present ages of son and father is 9 years and 27 years

Option A is correct.
What is Parallel line?The basic qualities listed below make it simple to identify parallel lines.
Parallel lines are defined as straight lines that are always the same distance apart.Parallel lines never intersect, regardless of how far they are extended in either direction.We have the parallel line AB || CD.
As, we know the parallel line have following property
Corresponding Angle are EqualAlternate Interior Angle are EqualAlternate Exterior Angle are EqualNow, from the figure using Corresponding angle
x = 72 degree
Thus, the required angle is 72 degree.

Which of the following ordered pairs are solutions to the system of equations below?
a. (1, 6)
b. (1, -6)
3. (-1, -6)
4. (-1, 6)
Given :-
A system of linear equation in two variables .To Find :-
The solution set of the system .Solution :-
The given system of equation is ,
[tex]\begin{cases} 3x + 2y = 9\dots (i) \\\\ y = 4x + 10 \dots (ii)\end{cases}[/tex]
Firstly , taking equation (ii) ,
[tex] y = 4x +10[/tex]
On subtracting y on both sides, we have ;
[tex] 4x - y +10 = 0[/tex]
Multiplying both sides by 2 ,
[tex] 2(4x -y+10)=2(0)[/tex]
Simplify,
[tex] 8x - 2y = -20 \dots (iii)[/tex]
Adding equation (i) and (iii) ,
[tex] 3x + 2y + 8x - 2y = -20+9[/tex]
Add and subtract the like terms ,
[tex] 11x = -11 [/tex]
Divide both sides by 11 ,
[tex] x = -1 [/tex]
Now substitute this value in equation (i) ,
[tex] 3(-1) + 2y = 9\\ \\ -3 + 2y = 9 \\\\ 2y = 9+3 \\\\ 2y = 12 \\\\ y =\dfrac{12}{2}\\\\ y = 6[/tex]
Hence the correct option is 4 (-1,6) .

A trapezoid has two bases and two legs. As seen, the lengths that represent the bases of the trapezoid are the parallel sides 8 and 6. This is because they go on straight and never intersect each other, which makes them parallel. The length that represents the height of the trapezoid is 4, which is the straight line that connects both bases.

Answer:
x = 5 , y = 15
Step-by-step explanation:
Since the figures are congruent then corresponding sides and angles are congruent , that is
WG = DG ( substitute values )
3x - 5 = 10 ( add 5 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
and
∠ WGF = ∠ DGF , that is
15x + y = 90 ( substitute x = 5 )
15(5) + y = 90
75 + y = 90 ( subtract 75 from both sides )
y = 15
