Answer: Height of tree = 26 ft
Make a triangle ABC with 40 degrees angle. The shadow is the base of the triangle equals 31 feet.
Base = AC = 31
Perpendicular = CB = ?
Hypotenuse = AB
Using trigonometric equation
tan 40 (deg) = CB / AC
CB = Tan 40 x AC
CB = 0.83909 x 31
CB = 26.011
Thus the height of the tree = 26 ft

Check if (1,6) is the solution to the system shown below
Answer:
no
Step-by-step explanation:
To determine if (1, 6) is a solution, substitute x = 1, y = 6 into the left side of both equations and if the value obtained equals the right side then it is a solution.
10(1) - 6 = 10 - 6 = 4 ≠ - 6
- 10(1) + 5(6) = - 10 + 30 = 20 ≠ 30
Then (1, 6 ) is not a solution to the system
Find the volume of the cylinder whose base area is (4x)2 and height is (5x)2.
Answer:
Step-by-step explanation:
The computation of the volume of the cylinder is shown below:
As we know that
The Volume of the cylinder is
= base × height
= (4x)^2 + (5x)^2
=16x^2 + 25x^2
= 41x^3
Hence, the volume of the cylinder is 41x^3
The volume of the cylinder will be [tex]20x^2[/tex] .
What is volume ?Volume is the amount of space that something contains or fills.
Volume [tex]=Length*Breadth*Height[/tex]
We have,
Base area [tex]=(4x)^2[/tex]
Height [tex]= (5x)^2[/tex]
So,
Volume of the cylinder [tex]=Base\ Area*Height[/tex]
[tex]= (4x)^2* (5x)^2[/tex]
Volume of the cylinder [tex]=20x^2[/tex]
Hence, we can say that the volume of the cylinder will be [tex]20x^2[/tex] .

The measure of ∠CBD is 45% of the measure of ∠ABC. Find the value of x.
Answer:
x = 49.5°
Step-by-step explanation:
∠ABC = 90°
∠CBD = 45%∠ABC
∠CBD = 0.45(90)
∠CBD = 40.5°
x = ∠ABC - ∠CBD
x = 90 - 40.5
x = 49.5°
A birthday cake is being made using a cylindrical baking pan. The radius of the pan is 4 inches, and the height is 5 inches.
Which formula represents the correct way to calculate the volume of the cake?
O V = (4)(5)
O V = r(4)(5)
O V = $(5) (4)
O V = $(4)?(5)
Answer:
the formula represent the correct way is π(4)^2 (5)
Step-by-step explanation:
The formula that represent the correct way to calculate is given below:
As we know that
Volume = πr^2 h
where
r denotes the radius i.e. 4 inches
And, h denotes the height i.e. 5 inches
Now placed these values to the above formula
So,
= π(4)^2 × 5
= 80π in^3
Hence, the formula represent the correct way is π(4)^2 (5)

A cube with an edge of length s has a volume of 27 units.
What is the length of s?
Answer:
s = 3
Step-by-step explanation:
The volume formula for a cube is V = s^3, where “s” is the edge length. Since we know the volume and need to find “s,” we just do the inverse operation for an exponent, which is a radical. The cubed root of 27 is 3, so there’s your answer! Hope this is helpful & accurate. Best wishes.
-12 x (1/3)? what is this equal to!
Answer:
-4
Step-by-step explanation:
Answer:
-4
Step-by-step explanation:
-12 times 1/3.
It's pretty much just -12x1, then divided by 3.
-12x1 is equal to -12.
Your equation is now simplified, making it easier to solve.
Your equation is: [tex]\frac{-12}{3}[/tex]
-12 divided by 3 is -4, because when a negative number is divided (or multiplied) by a positive number, the quotient (or product) is negative.
-12 x (1/3) = -12/3 = -4.
Use the distributive property to simplify the following expression: 3 (2 + 5z.)
Answer:
6+15z
Step-by-step explanation:
We multiply 3 to 2+5z. So, (3x2)+(3x5z)

Answer:
x ≈ 5.1
Step-by-step explanation:
Using the sine ratio in the right triangle
sin25° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{12}[/tex] ( multiply both sides by 12 )
12 × sin25° = x , that is
x≈ 5.1 ( to the nearest tenth )

Answer:
$2,725
Step-by-step explanation:
The maximum number of days is 7.
The cost per days is $375.
The cost for 7 days is 7 * $375 = $2,625.
The owner applies a $100 fee for cleaning which must be added to the cost of the days.
$2,625 + $100 = $2,725
The greatest value for the range is the greatest cost there can be which is $2,725.

What is the equation of the line that passes through the point (7,-6) and has a slope of -2?
Answer:
y=-2+8
Step-by-step explanation:
The answer is y=-2+8 because of course the slope has to be -2 as you stated in your Question. So all you have to do is change the Y-Intercept until you reach the point. Since the Slope is negative, the Y-Intercept will rise until you reach your point. You may double check my answer to see if it is right, it is up to you. If you find any fault in my answer please let me know. Have a good day!
A guy wire supporting a radio tower is attached to the tower 128 feet above the ground. The wire makes a 45 degree angle with the ground. How long is the guy wire
Answer:
181 feet
Step-by-step explanation:
From the the diagram attached ,
Sinθ = a/b..................... Equation 1
Where θ = angle to the horizontal, a = Height of the tower, b = length of the wire.
make b the subject of the equation
b = a/sinθ................. Equation 2
Given: a = 128 feet, θ = 45°
Substitute these values into equation 2
b = 128/sin45°
b = 128/0.7071
b = 181 feet
b = 181 feet
