We have been given the two lengths as x and y So, the value of x would be equal to root 80.
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly canceled from both the numerator and the denominator.
Thus, a = px, b = qx
we have been given the two lengths as x and y.
From the figure, we know that
11: y = y: 5
Express in fraction
11/y = y / 5
y^2 = 5(11)
y ^2 = 55
So, y = √55
From Pythagoras theorem;
[tex]x^{2} =5^{2} +y^{2} \\\\x^{2} =5^{2} +55 \\\\x^{2} =25 + 55\\\\x^{2} =80\\\\x = \sqrt{80}[/tex]

Hello. Please help me answer this.
Answer:
The area of the shape is 49.
Step-by-step explanation:
The shape is a trapizoid, so we use the formula: I've attached an image below.
H stands for height, the height is 7. b1 is 3 (the first base length) and b2 is 11 (the second base length.)
Now, we plug it into the formula.
A=1/2(7)(3+11)
A= 49.

The possible values of x in the polynomial is x = 2
What is a polynomial?Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.
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 polynomial equation be represented as A
Now , the value of A is
To find the possible values of x in the equation 8 - x³ = 0, we need to solve for x.
Starting with 8 - x³ = 0, we can add x³ to both sides of the equation:
8 = x³
Now, we can take the cube root of both sides:
∛8 = ∛x³
2 = x
So, the only possible value of x that satisfies the equation is x = 2
We can check this by substituting x = 2 into the original equation:
8 - 2³ = 8 - 8 = 0
Hence , the only possible value of x that satisfies the equation is x = 2

There are 12 inches in foot and 3 in a yard .work out the number of inches in 7 yard
Answer:
Step-by-step explanation:
Remark
If you learn how to do this, a part of science called dimensional analysis will come more easily to you. It looks like this.
7 yds [3 ft/yd] [12 in / ft] = 252 inches.
Notice how it works. In the first set of brackets, the yards cancel. You have 21 feet. In the second set of brackets, the feet cancel, and you are left with inches.
Proportions
If this does not appeal to you, you can do it the standard way.
1 yard / 3 feet = 7 yards / x (feet) Cross Multiply
1 yard * x = 7 yards * 3 feet. Divide by yards
1 yard * x / yard = 7 yards * 3 feet/yds The yards cancel
x = 21 feet
1 foot / 12 inches = 21 feet / x Cross Multiply
1 foot * x = 12 inches * 21 feet Divide by ft
1 foot *x / foot = 12 inches *21 ft/ft
x = 252 inches
Answer

Answer:
∠b = 53°
Explanation:
Complimentary angles are when two angles sum up to 90°
Here given:
∠a : 37°
∠b : missing angle
These angles sum up to 90 degree:
x + 37 = 90°
x = 90° - 37°

x^2-7x-34=10
Please help me answer this question thank you
Answer:
X can either be -4 or 11.
Step-by-step explanation:
[tex]x^{2} - 7x - 34 = 10\\\\Make this into a quadratic equation:\\\\x^{2} - 7x - 44 = 0\\ \\Find the factor pairs of -44 and their sums:\\-1,44 sum is 43\\ -2,22 sum is 20\\-4,11 sum is 7\\1, 44 sum is 45\\2, -22 sum is 20\\4, -11 sum is -7\\\\\\Find a sum that is equal to the coefficient of x which is -7 in this case. As we can see the pair 4, -11 corresponds to a sum of -7, therefore we can use this to factorise this quadratic equation and get two solutions:\\\\(x + 4) (x - 11) = 0\\[/tex]
If we set (x+4) to zero then x equals -4
If we set (x-11) to zero then x equals to 11.
So x can be -4 or 11.

A blimp provides aerial television views of a tennis game. The television camera sights the stadium at a 9° angle of depression. The altitude of the blimp is 300m. What is the line-of-sight distance from the television camera to the base of the stadium? Round to the nearest hundred meters.
9 °
300 m
The line-of-sight distance from the television camera to the base of the stadium is 1918.16 meters
What is a right triangle?
A right triangle has one of its angles as 90 degrees.
Therefore, the angles and side can be found using trigonometric ratios.
Hence, the line-of-sight distance from the television camera to the base of the stadium is hypotenuse side of the right triangle formed.
sin 9° = opposite / hypotenuse
sin 9° = 300 / h
h = 300 / sin 9
h = 300 / 0.15643446504
h = 1918.15856777
h = 1918.16 meters

Melinda leaves her house and walks north 6 blocks. She turns and heads east 8 blocks until she reaches Mary’s house. What is the shortest distance between Melinda’s house and Mary’s house?
The shortest distance between Melinda’s house and Mary’s house will be equal to 10 blocks.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal the square of the sum of the other two sides.
Here we have the condition that Melinda leaves her house and walks north 6 blocks. She turns and heads east 8 blocks until she reaches Mary’s house.
Now we need to calculate shortest distance between Melinda’s house and Mary’s house.
The traingle is made from the given question and the shortest distance between Melinda's and Mary’s house will be the hypotenuse of the triangle.
So from the Pythagorean theorem:-
D²=6²+4²
D²=36+16
D²=100
D=10
Hence the shortest distance between Melinda’s house and Mary’s house will be equal to 10 blocks.

Which of the following are examples of rational numbers? Select all that apply.
3 Answers:
Choice A
Choice D
Choice E
=====================================================
Explanation:
The list of perfect squares is:
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, ...
If we apply the square root to any of those numbers, then the number is rational.
For example, [tex]\sqrt{25} = 5 = \frac{5}{1}[/tex]
A rational number is any fraction of two integers, where zero is not in the denominator.
Based on this, we can see that choice A represents a rational number because we are summing rational numbers.
More specific proof is to write [tex]\sqrt{4} + \sqrt{16} = 2 + 4 = 6 = \frac{6}{1}[/tex] showing it is rational.
---------------------
Choice B is ruled out because [tex]\sqrt{5}[/tex] is irrational. We cannot write it as a fraction of two integers.
Choice C is ruled out for similar reasoning as choice B. This time [tex]\sqrt{24}[/tex] is irrational.
----------------------
Choice D is another answer because [tex]2*\sqrt{4} = 2*2 = 4 = \frac{4}{1}[/tex] is rational.
Choice E is another answer as well because [tex]\sqrt{49}*\sqrt{81} = 7*9 = 63 = \frac{63}{1}[/tex] is rational.
Choice F is ruled out because [tex]\sqrt{12}[/tex] is irrational, which in turn makes [tex]3\sqrt{12}[/tex] irrational as well.
