Answer:
\(2\sqrt{5}\)
Step-by-step explanation:
You can use the Pythagorean Theorem, which is \(a^{2}+ b^{2}= c^{2}\). So the the distance from -9 to -5 is 4 and the distance from 8 to 6 is 2.
So \(4^{2} +2^{2} =c^{2}\). Which equals \(20=c^{2}\).
Then you square root \(c^{2}\) to make it c, then you do that to the other side. So you have \(\sqrt{20}=c\).
Which equals \(2\sqrt{5}\).
Or you can use the Distance Formula, which is \(\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }\).
The \(x_{1}\) is -5 and the \(x_{2}\) is -9. The \(y_{1}\) is 6 and the \(y_{2}\) is 8. When you plug that in you get \(\sqrt{(-9--5)^{2} +(8-6))^{2} }\). When you simplify that you get \(\sqrt{20}\).
Which equals \(2\sqrt{5}\).

Hey there!
“x – 3 < 2”
Let’s change your current question into a(n) equation to make it EASIER to solve (this is for temporary purposes ONLY)
• Temporary question
x – 3 = 2
• First: ADD BOTH SIDES by 3
x – 3 + 3 = 2 + 3
• CANCEL: –3 + 3 because that gives you 0
• KEEP: 2 + 3 because that helps solve for x
• New temporary question: 2 + 3 = x
2 + 3 = 5
The temporary question answer is: x = 5 ✅
NOW LETS SOLVE FOR YOUR ACTUAL EQUATION (just saying it REQUIRES the SAME steps as the temporary question just a TAD bit differently!)
x – 3 < 2
• FIRST: ADD both SIDES BY 3
x – 3 + 3 < 2 + 3
• CANCEL: –3 + 3 because that gives you 0
• KEEP: 2 + 3 because that helps us compare the answer with x
• New equation: x < 2 + 3
2 + 3 = 5
x < 5
Answer to your given question is: x < 5 ☑️

A square is a type of rectangle, so any square can also be called a rectangle. However, not all rectangles are squares.

John bought a shirt at ksh 500 and marked it at Ksh 600. A customer bought it at ksh 550. What was the percentage discount?
Answers
Answer:
The original price of the shirt was Ksh 500 and it was sold for Ksh 550.
The discount is the difference between the original price and the selling price, which is Ksh 500 - Ksh 550 = Ksh -50.
To find the percentage discount, we can use the formula:
percentage discount = (discount ÷ original price) × 100%
percentage discount = (-50 ÷ 500) × 100%
percentage discount = -10%
Therefore, the percentage discount is 10%.

A strategy for teaching division is by repeated subtraction. It involves repeatedly subtracting the same integer from a big number until the result is zero. It is a fantastic approach to teach kids about division. A technique called repeated subtraction, commonly referred to as division, removes an equal amount of items from a group.
Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.

Given that,
The difference between 4 and the sum of a number and is equal to twice that number.
Repeated subtraction is a method for teaching division. Until the result is zero, the same integer must be repeatedly subtracted from a large number. Repeated subtraction, sometimes known as division, is a method that takes an equal number of elements out of a group.
Division's opposite is multiplication. If 3 groups of 4 total up to 12, then 4 are in each group when 12 is divided into 3 equal groups. The fundamental goal of division is to produce equal groups or to determine how many individuals are in each group following a fair distribution.
x×4+4=2x-4
Subtracting 4 on both sides
4x+4-4=2x-4-4
4x=2x-8
Now, substracting 2x from both sides
4x-2x=2x-8-2x
2x=-8
x=-4

Based on this theory, what distance will the handler move from the starting point to the return point if he creates an arc of a circle with radius 70 feet?

3846.5 feet
109.9 feet
1758.4 feet
Answers
The Distance the handler will move from the starting point to the return point will be approximately 439.8204 feet.
The distance the handler will move from the starting point to the return point when creating an arc of a circle with a radius of 70 feet, we need to find the length of the arc.
The formula to calculate the length of an arc is given by:
Length of arc = (θ/360) * 2πr
Where:
θ is the central angle of the arc (in degrees)
r is the radius of the circle
In this case, since the handler is creating a full circle, the central angle is 360 degrees.
Length of arc = (360/360) * 2π * 70
Length of arc = (1) * 2π * 70
Length of arc = 2π * 70
Length of arc = 140π
To find the approximate value in feet, we can use the approximation π ≈ 3.14159.
Length of arc ≈ 140 * 3.14159
Length of arc ≈ 439.8204 feet
Therefore, based on the given theory and using a circle with a radius of 70 feet, the distance the handler will move from the starting point to the return point will be approximately 439.8204 feet.

The radius of a circle is 3 feet. What is the length of a 75° arc?
Answers
Therefore , the solution of the given problem of circle comes out to be arc length 3.93 feet.
How do circles work?Every area of the plane that is separated by a specific amount from this additional point makes a circle (center). As a result, it is a curve made up of spots that are separated from one another on the surface. Additionally, it rotates similarly about the centre at every angle. Every collection of endpoints in the confined, two-dimensional sphere of a circle is uniformly spaced apart from the "centre."
Here,
A circle with a radius of 3 feet is equal to its diameter as follows:
=> C = 2πr = 2π(3) = 6π feet
Since there are 360° of angles in a circle's centre, the angle for a 75° curve is:
5/24 of a complete circle is 75/360.
Therefore, the 75° arc's extent is
5/24 × 6π = 5π/4 ≈ 3.93 feet

Find the probability that a randomly selected point within the square falls in the red-shaded triangle. 3 3 4 P = [?] 4
Answers
The required probability is 3 √7 / 32.
Given, a square with sides of length 4 units and a red-shaded triangle with sides 3 units, 3 units and 4 units. We need to find the probability that a randomly selected point within the square falls in the red-shaded triangle.To find the probability, we need to divide the area of the red-shaded triangle by the area of the square. So, Area of square = 4 × 4 = 16 square units. Area of triangle = 1/2 × base × height.
Using Pythagorean theorem, the height of the triangle is found as: h = √(4² − 3²) = √7
The area of the triangle is: A = 1/2 × base × height= 1/2 × 3 × √7= 3/2 √7 square units. So, the probability that a randomly selected point within the square falls in the red-shaded triangle is: P = Area of triangle/Area of square= (3/2 √7) / 16= 3 √7 / 32.

The Weaver family went to dinner and spent $52.75. They had great service so they tipped the server 22%. What was the Weaver's total bill?
Answers
To find the total amount that the Weaver family spent on their dinner, you need to add the tip to the original bill. To calculate the tip, you need to multiply the cost of the dinner by the percentage of the tip: $52.75 × 22% = $11.61.
Then, you can add the tip to the original bill to find the total cost of the dinner: $52.75 + $11.61 = $64.36.
Therefore, the Weaver family's total bill for their dinner was $64.36.

Equation of line parallel to y = − 2 x − 3 and passing through the point (3,-3) is y = -2x + 3.

Two lines are parallel lines if they do not intersect.

f(x)= mx + b and g(x)= nx + c are parallel if m = n.
According to the given question:
Given equation of line is y = −2x − 3
If the new line is parallel, then it will have the same slope.
y = -2x + b
