Susan is flying a kite, which gets caught in the top of a tree. Use the diagram to estimate the height of the tree. EXPLAIN HOW TO GET YOUR ANSWER PLEASE!
It's 87 feet I got the answer right
The height of the tree is estimated as 87 ft.
The height of the tree can be estimated using trigonometric ratios. Therefore,
tan 44° = opposite / adjacent
tan 44° = h / 90
h = 90 tan 44°
h = 90 × 0.9656887748
h = 86.9119897326
h ≈ 87 ft
Therefore, the height of the tree is estimated as 87 ft.

Today is the birthday of Rahul and he is 3 times
as old as Nirmala. In 13 years, Rahul will be one
year less than twice as old as Nirmala will be
then. The age of Rahul today is:
a. 30 years
c. 49 years
b. 36 years
d. 30 years
Answer:
b. 36 years
Step-by-step explanation:
Today
Nirmala = x years
Rahul = 3x years
In 13 years
Nirmala = 3x + 13 years
Rahul = 2(x+13) - 1
3x + 13 = 2(x+13) - 1
3x + 13 = 2x + 26 - 1
3x + 13 = 2x + 25
3x - 2x = 25 - 13
x = 12
Nirmala = x years
= 12 years
Rahul = 3x years
= 3(12)
= 36 years
The age of Rahul today is 36 years

find the volume of the cylinder pictured below use 3.14 for pi give your answer rounded to the nearest tenth height 21ft diameter 10ft
Given:
Height of the cylinder = 21 ft
Dimeter of the cylinder = 10 ft
To find:
The volume of the cylinder.
Solution:
We have,
Dimeter of the cylinder = 10 ft
So, radius is half of diameter, i.e., 5 ft.
Volume of the cylinder is
[tex]V=\pi r^2h[/tex]
Where, r is the radius and h is the height.
Putting [tex]\pi=3.14[/tex], r=5 and h=21, we get
[tex]V=(3.14)(5)^2(21)[/tex]
[tex]V=(3.14)(25)(21)[/tex]
[tex]V=1648.5[/tex]
Therefore, the volume of the cylinder is 1648.5 cubic ft.

What is the solution to this system of equations? A.P.E.X btw
A) (4, -2)
B) (-2, 4)
C) (-1, 2)
D) (2, -1 )
The required solution to the system of equations is (x, y) = (-2, 4). Option B is correct.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
To solve this system of equations, we can set the two expressions for y equal to each other, since they both represent the same value of y,
x + 6 = -0.5x + 3
Simplifying and solving for x, we get:
1.5x = -3
x = -2
Now that we have the value of x, we can substitute it into one of the original equations to find the value of y. Using the first equation, we have,
y = x + 6
y = -2 + 6
y = 4
Therefore, the solution to the system of equations is (x, y) = (-2, 4).

Find the measure of the numbered angles in each rhombus
Answer:
Angle 1 = 22°
Angle 2 = 68°
Angle 3 = 68°
Angle 4 = 90°
Step-by-step explanation:
It is a rhombus by the definition:
A rhombus is a quadrilateral whose all four sides are equal in length and opposite sides are parallel to each other. However, the angles are not equal to 90°.
The properties of rhombus is:
(1) Opposite angles are equal
(2) All sides are equal and, opposite sides are parallel to each other
(3) Diagonals bisect each other perpendicularly
(4) Sum of any two adjacent angles is 180°
By property (3):
Angle 4 = 90°
By (1) and properties of isosceles triangle in the top right triangle:
Angle 2 = Angle 3 = 68°
In the top triangle:
Angle 1 + Angle 2 + 90° = 180° (Angle sum of triangle)
Angle 1 = 22°

- Functions F and A are defined by these equations below. Which function has a greater value when x is 2.5?
A. F(x) = 80-15x
B. A(x) = 25 + 10x
Answer:
The answer is D- A(x)=25+10x
Step-by-step explanation:
I cant really explain how i got the answer but i got it right
The function A(x) has greater value then F(x) for x = 2.5.
What is a function?A function is a relation between a independent variable and a dependent variable such that the value of dependent variable depends upon the independent one.
Given are two functions of [x] as follows -
F(x) = 80 - 15x
A(x) = 25 + 10x
We have the following functions -
F(x) = 80 - 15x
A(x) = 25 + 10x
Now, we will evaluate each function at x = 2.5.
F(2.5) = 80 - 15 x 2.5 = 42.5
and
A(2.5) = 25 + 10 x 2.5 = 50
It can be seen that A(2.5) > F(2.5)
So, the function A(x) has greater value then F(x) at x = 2.5
Therefore, the function A(x) has greater value then F(x) for x = 2.5.

The cost of 3 pencils and 2 markers is $1.30.
The cost of 2 pencils and 3 markers is $1.20.
What is the total cost of 7 pencils and 7 markers?
Answer:
$3.50
Step-by-step explanation:
Given that the cost of 3 pencils and 2 markers is $1.30. Let the cost of a pencil be $p and that of a marker be $m then
3p + 2m = 1.30
Also, the cost of 2 pencils and 3 markers is $1.20 will result
2p + 3m = 1.20
Solve both simultaneously
3p + 2m = 1.30
2p + 3m = 1.20
multiply the first by 2 and the second by 3
6p + 4m = 2.60
6p + 9m = 3.60
subtract the second from the first
4m - 9m = 2.60 - 3.60
-5m = -1
Divide both sides by -5
m = 0.20
substitute into equation 1
3p + 2(0.2) = 1.30
3p + 0.4 = 1.30
3p = 1.30 - 0.40
3p = 0.90
Divide both sides by 3
p = 0.30
The total cost of 7 pencils and 7 markers
= 0.30 * 7 + 0.20 * 7
= 2.10 + 1.40
= $3.50
