Answer:
Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
The two requirements for a proportional relationship are: The ratio of the two variables maintain the same ratio.

A support wire is attached to the top of an antenna. The support wire connects
to the ground 15 feet from the bottom of the antenna. The support wire and the
ground meet at an angle with measure 70°, as shown.
Antenna
70°
15 ft-
To the nearest foot, what is the height of the antenna?
The antenna is
feet tall.
Answer:
Step-by-step explanation:
The antenna height is 41.23 feet if the support wire is attached to the top of the antenna.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
A support wire is attached to the top of an antenna. The support wire connects to the ground 15 feet from the bottom of the antenna.
Let x be the height of the antenna.
We can find the length of the antenna using the trigonometric ratios:
As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
Applying tan ratio in the right angle triangle:
tan70 = x/15
x =15tan70
x = 41.212 feet ≈ 41.23 feet
Thus, the height of the antenna is 41.23 feet if the support wire is attached to the top of the antenna.

At a certain time of day, the sun shines on a large flagpole causing a shadow that is twice as long as the flagpole is tall what is the height of the flagpole to the nearest tenth of a foot?
350ft
Answer:
156.5
Step-by-step explanation:
The height of the flagpole to the nearest tenth of a foot is 156.5 ft.
Word Problems Using Pythagoras Theorem:Word Problems involving the use of the Pythagoras theorem need careful understanding to discern the complexity of the variables given, the using the Pythagoras theorem to solve the eqaution.
The Pythagoras Theorem states that the sum of the squares of the opposite side and the adjacent side is equal to the hypotenuse square.
From the information;
The large flagpole height = adjacent = xThe shadow of the flagpole = opposite = 2xThe hypotenuse = 350 ftUsing the Pythagoras theorem, we have;
hyp² = opp² + adj²
350² = (2x)² + x²
350² = 4x² + x²
122500 = 5x²
x² = 122500/5
x² = 24500
x = √24500
x = 156.5 ft
Therefore, we can conclude that the height of the flagpole is approximately 156.5 ft.

Answer:
[tex] m\angle XYZ = 70\degree [/tex]
Step-by-step explanation:
By exterior angle theorem:
4x° = 2x° + 70°
4x° - 2x° = 70°
2 x° = 70°
2x = 70
x = 70/2
x = 35
[tex] m\angle XYZ = 2x\degree [/tex]

Rachel ran 3 miles when she was training for a race. How many feet did she run?
Answer:
15,840 i did this in test and got 100%
Step-by-step explanation:
The total feet ran by Rachel is given by the equation A = 15,840 feet
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the total miles ran by Rachel be A = 3 miles
Now , the value of 1 mile = 5,280 feet
Substituting the values in the equation , we get
The distance of 3 miles in feet = 3 x value of 1 mile
On simplifying the equation , we get
The distance of 3 miles in feet = 3 x 5,280
The distance of 3 miles in feet = 15,840 feet
Therefore , the distance ran by Rachel A = 15,840 feet
Hence , the equation is A = 15,840 feet

Answer:
I think it C
Step-by-step explanation:
Let's solve your equation step-by-step.
(k−4)2=9
Step 1: Simplify both sides of the equation.
k2−8k+16=9
Step 2: Subtract 9 from both sides.
k2−8k+16−9=9−9
k2−8k+7=0
Step 3: Factor left side of equation.
(k−1)(k−7)=0
Step 4: Set factors equal to 0.
k−1=0 or k−7=0
k=1 or k=7
Answer:
k=1 or k=7
Hope this helps! :)
Square both sides:
K -4 = sqrt(9)
With the answer being a square root rewrite with a postive and negative value:
K-4 = sqrt(9)
And
K-4 = -sqrt(9)
Simplify each:
K-4 = 3
And
K-4 = -3

The sum of three numbers is 235. The second number
is 15 more than the first number, and the third number
is 8 times the first number. Find the second number.
Answer:
37
Step-by-step explanation:
x = 1st number
y = 2st number
z = 3rd number
x + y + z = 235
y = x + 15
z = 8x
x + x + 15 + 8x = 235
10x = 220
x = 22
y = 37
z = 176
The second number is 37.
Given that,
The sum of three numbers is 235. The second number is 15 more than the first number, and the third number is 8 times the first number.Here we assume the first number be x, second number be y, and third number be z.Based on the above information, the calculation is as follows:
x + y + z = 235
y = x + 15
z = 8x
Now
x + x + 15 + 8x = 235
10x = 220
x = 22
So,
y = 22 + 15
= 37
