Check the picture below, so hmm we know that much, and we can also more or less see that PR is the longest side, let's check the length of the other two sides
[tex]~~~~~~~~~~~~\textit{distance between 2 points} \\\\ P(\stackrel{x_1}{6}~,~\stackrel{y_1}{1})\qquad Q(\stackrel{x_2}{3}~,~\stackrel{y_2}{5})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ PQ=\sqrt{[3 - 6]^2 + [5 - 1]^2}\implies PQ=\sqrt{(-3)^2+4^2}\implies \boxed{PQ=5} \\\\[-0.35em] ~\dotfill\\\\ Q(\stackrel{x_1}{3}~,~\stackrel{y_1}{5})\qquad R(\stackrel{x_2}{11}~,~\stackrel{y_2}{11})~\hfill QR=\sqrt{[11 - 3]^2 + [11 - 5]^2} \\\\\\ QR=\sqrt{8^2+6^2}\implies \boxed{QR=10}[/tex]
if that's true, the triangle is indeed a right-triangle, then hmmmm most likely using the pythagorean theorem PR² = PQ² + QR², let's check

calculate the equation of straight line passing through (5,-10) and making equal but opposite intercept.
Answers
The equation of the straight line passing through (5,-10) and making equal but opposite intercept is y = -4x + 10.
To solve the problem, we need to know the equation of a straight line
Equation of a straight line in slope intercept formThe equation of a straight line in slope intercept form is given by y = mx + c where
m = slope and c = y- intercept.Given that the straight line passes through the point (5, -10) and making equal but opposite intercept, its intercept is at (-5, 10)
The gradient of the lineWe need to find the gradient, m by making m subject of the formula in y.
So, m = (y - c)/x
With
x = 5, y = -10 and c = 10, we havem = (y - c)/x
m = (-10 - 10)/5
m = -20/5
m = -4
Substiting m and c into y, we have
y = mx + c
y = -4x + 10
So, the equation of the straight line passing through (5,-10) and making equal but opposite intercept is y = -4x + 10.

The diameter of a circle is 28 inches. What is the circle's circumference
Answers
Answer: 87.92.
Step-by-step explanation: To find the circumference of a circle, you need the following equation:
2 x π x r, where π is ≈ 3.14 and r is the circle's radius. If you are ever given the diameter instead of the radius, just cut the diameter in half. In this case, the diameter was given, so we need to cut 28 in half, which makes 14. Your equation should look like this:
2 x 3.14 x 14 ≈ 87.92.

What is 527 x 36 with an area model???
Answers
Answer:
18972
Step-by-step explanation:
With an area model, the model will have dimensions of 576 and 36. The product of the units will be within the model.
The value of the equation is A = 18,972
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 first number be p = 527
Let the second number be q = 36
Now , the equation will be
A = p x q
Substituting the values in the equation , we get
A = 527 x 36
On simplifying the equation , we get
A = 18,972
Hence , the equation is A = 18,972

π/4 radiansπ/4 radiansStep-by-step explanation:
The relationship between angle measures in degrees and angle measures in radians does not depend on the radius of the circle. It is always ...
180° = π radians
__
Then an angle of 45° will be ...
45° × (π radians)/(180°) = π/4 radians
This value is the same for a radius of 5 cm or of 1 cm.
_____
Additional comment
We have made the conversion from degrees to radians using a conversion factor that has radians in the numerator and degrees in the denominator. When we mutiply by this factor, the units of degrees cancel, leaving units of radians. We use a conversion factor that has the same angle value in numerator and denominator, so it doesn't change the angle we're multiplying. It only changes the units.
The same relation can be expressed as a proportion:
(π radians)/180° = (x radians)/(45°)
When you multiply this equation by 45° on both sides, you get the equation we used above.

Reduced fraction:
1/2
Therefore, 27/54 simplified to lowest terms is 1/2.
Answer:
27/54 =1/2
Step-by-step explanation:
27 and 54 are both multiples of 9, so 9 is a common divisordivisor.
Divide numerator and denominator by 91:
(27/9) / (54/9) = 3/6
Now 3 and 6 are both multiples of 3, so 3 is a common divisor
Divide numerator and denominator by 3:
(3/3) / (6/3) = 1/2
1 and 2 has no common divisors so 1/2 is the final answer
