Step-by-step explanation:
Matt can walk 500 m from his home on King Street, and then 900m along Queen Street to go to his school. He can also walk across a diagonally across a park from his home to his school. Assuming King Street and Queen Street meet at right angles, how far does he walk across the park to go to school?
Answer:
He walks 1030 meters if he walks across the park.
Step-by-step explanation:
In order to solve this question we will need to know that [tex]c^{2} = a^{2} + b^{2}[/tex] (were c is the length of the hypotenuse (the diagonal line) of a right angle triangle, and a and b are the legs (the sides that form a right angle). So them means that.....
Let "c" be the distance he will need to walk if he was going to go through the park
Let "a" be the distance he walks on King Street
Let "b " be the distance he walks on Queen Street, then.....
[tex]c^{2} = a^{2} + b^{2}[/tex]
[tex]c = \sqrt{a^{2} + b^{2} }[/tex]
(Now plug in the values of a and b and get.....)
c = [tex]\sqrt{500^{2} + 900^{2} }[/tex]
c = [tex]\sqrt{1060000 }[/tex]
c = 1029.563014............
So I would assume that you have to round to the nearest meter. And as a result we get 1030 meter.

Air traffic controllers are watching two planes on radar to ensure there is enough distance between them. Plane A took off at 10:00 a.m., and plane B took off at the same runway 5 minutes later. Both planes are flying at the same direction angle and the same path. At 10:10 a.m., the airport’s radar system detected plane A at (24, 18) and plane B at (8, 6).

Find the Sum (3x^2+ 4x-1) + (-2x^2 -3x+2)
The sum of the equation is A = x² + x + 1
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 sum of the equations be represented as A
Now , the value of A is
Let the first equation be P
The value of P = 3x² + 4x - 1
Let the second equation be Q
The value of Q = -2x² - 3x + 2
Now , the value of A = P + Q
Substituting the values in the equation , we get
A = ( 3x² + 4x - 1 ) + ( -2x² - 3x + 2 )
On simplifying the equation , we get
A = ( 3x² - 2x² ) + ( 4x - 3x ) + ( 2 - 1 )
A = x² + x + 1
Therefore , the value of A is x² + x + 1
Hence , the equation is A = x² + x + 1

Replace * with a monomial so that the expression represents the square of a binomial. *+24x+9
Answer:
[tex]*+24x+9 = 16x^2 + 24x + 9[/tex]
Step-by-step explanation:
Given
[tex]* + 24x + 9[/tex]
Required
Fill in the gap
[tex]* + 24x + 9[/tex]
Express 24x as a sum of equal halves
[tex]* + 12x + 12x + 9[/tex]
Group into two
[tex](* + 12x) + (12x + 9)[/tex]
Factorize 12x + 9
[tex](* + 12x) + 3(4x + 3)[/tex]
Ignore the incomplete part and focus on (4x + 3)
Since the binomial is a square, then the factors of the binomial are :
(4x + 3) and (4x + 3)
So, we have:
[tex](* + 12x) + 3(4x + 3) = (4x + 3)(4x + 3)[/tex]
Expand
[tex](* + 12x) + 3(4x + 3) = 16x^2 + 12x + 12x + 9[/tex]
[tex](* + 12x) + 3(4x + 3) = 16x^2 + 24x + 9[/tex]
Hence:
[tex]*+24x+9 = 16x^2 + 24x + 9[/tex]

Name the postulate, if possible, that makes the triangles congruent.?
Answer: The postulate is stated as follows: When the two sides and the other side of a triangle are equal to the corresponding sides of another triangle, both triangles are said to be congruent triangles.
Step-by-step explanation:
Congruent triangles are triangles that have their corresponding sides equal. For a triangle (three angles), to be termed as congruent it must have each of its triangle equal to the corresponding sides of another triangle.

A coordinate grid with a line passing through the points at (negative 3, 3), (0, 1), and (3, negative 1).
Answer:
See attached graph
Step-by-step explanation:
The equation is y-3=(x + 6)
Write the equation in a slope intercept form, then graph the equation on a graph tool to see the points that line on the line.
Alternatively , using the coordinates in the answer choices given, input them in the equation of the graph and select the answer choice that has all its coordinates true to the equation.
y-3 = x+6 -----can be written as : y= x+9
Graph y= x+9 to see the graph and the points that are on the line as attached.
The line passes through points (-5, 4) and (-4, 5).
Hence, option E is correct.
Use the concept of drawing a graph defined as:
Drawing the curve that represents a function on a coordinate plane is known as graphing a function. Every point on the curve will satisfy the function equation if the curve (or graph) reflects the function.
The given equation of a line:
y – 3 = (x + 6)
To plot the graph:
Put x = 0 we get y = 9
put x = 1 we get y = 10
put x = 2 we get y = 11
put x = 2 we get y = 12
proceed similarly.
Now plot the curve by addressing these points.
Hence,
The line passes through points (-5, 4) and (-4, 5) which is option E.

Matt and Ash are selling fruit for a school fundraiser. Customers can buy small boxes of fruit or
large boxes of fruit. Matt sold 3 small boxes and 5 large boxes for a total of $47. Ash sold 11 small
boxes and 10 large boxes for a total of $114. What is the cost of a small box of fruit?
Answer: The cost of a small box is $4. The cost of a large box is $7.
Step-by-step explanation:
Let s = cost of a small box and L = cost of a large box
3s + 5L = 47
11s + 10L = 114
Multiply the top equation by -2 to combine with the second equation
-6s - 10L = -94
+11s +10L = 114
L cancels out, now solve for s
5s = 20
s = 4
Now, plug the value of s back into an equation to find the value of L
3(4) + 5L =47
12 + 5L = 47
5L = 35
L = 7

Answer:
The answer is D-16
Step-by-step explanation:
Since we have x on one side, and 49 degrees on the other, both angles are the same, so we subtract 1 from 49 to get 48, so that 3x has to equal 48. So we just divide 48 by 3 to get 16, so x = 16.
