Answer:
this is what I found "The bearing of a point is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the centre of the compass with the point. A bearing is used to represent the direction of one point relative to another point."
I can't really make sense of it though...
Answer:
What is the difference between constructing a square and constructing a regular hexagon?
The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction.
The radius of the circle is used for the square construction, but the diameter of the circle is used for the regular hexagon construction.
The square will need two arcs along the circle, but the hexagon will need two arcs above and two arcs below the diameter of the circle.
The square will need six arcs along the circle, but the hexagon will need two arcs above and two arcs below the diameter of the circle.

A test is normally distributed with a mean of 70 and a standard deviation of 10. Todd scores a 55 on the test. Select the answer from the drop-down menu to correctly complete the statement. Based on the mean of 70 and his raw score of 55, Todd’s z-score must be
Answer:
Todd's Z-score is - 0.27
Step-by-step explanation:
Explanation:-
Step(i):-
Given data A test is normally distributed with a mean of 70 and a standard deviation of 10.
Mean of the population 'μ' = 70
Standard deviation of the Population ' σ ' = 10
let 'x' be the random variable in normally distributed
Step(ii):-
Given raw score 'x' = 55
Todd's Z-score
[tex]Z = \frac{x-mean}{S.D}[/tex]
[tex]Z = \frac{55-70}{55}[/tex]
Z = -0.27
Final answer:-
Todd's Z-score is - 0.27
find the product of -8 (-12)
Answer:
-8(-12) = 96
Step-by-step explanation:
The word product, in mathematical terms, is the answer you get after multiplying something. So, to find the product of -8(-12), you have to multiply. A negative times a negative is equal to a positive, so -8 times -12 is equal to positive 96.
Find the area of a regular hexagon with a perimeter of 72 inches. *
1 point
360.055 square inches
374.112 square inches
381.489 square inches
The area of the hexagon is the amount of space on it
The area of the hexagon is 374.112 square inches
How to detemine the area of the hexagpon?The perimeter is given as:
P = 72 inches
The length of the hexagon is calculated using:
L = P/6
So, we have:
L =72/6 = 12
The area is then calculated as:
A = 1.5[tex]\sqrt 3[/tex] * L^2
This gives
A = 1.5[tex]\sqrt 3[/tex] * 12^2
Evaluate the product
A = 374.112
Hence, the area of the hexagon is 374.112 square inches

Step-by-step explanation:
the vertex of this parabola is at (3,-2). When the x-vaue is 4, the y-value is 3. What is the coefficient of the squared expression in the parabola equation?
=========================================================
Explanation:
Vertex form is
y = a(x-h)^2 + k
We are told the vertex is (3,-2), so we know (h,k) = (3,-2)
y = a(x-h)^2 + k will update to y = a(x-3)^2 - 2
--------
Then we also know that (x,y) = (4,3) is a point on the parabola. Plug those x and y values into the equation and solve for 'a'
y = a(x-3)^2 - 2
3 = a(4-3)^2 - 2
3 = a(1)^2 - 2
3 = a - 2
3+2 = a
5 = a
a = 5
This is the coefficient of the x^2 term since the standard form is y = ax^2+bx+c.

How are the following three expressions different from each other, if indeed they are? do not just state the value of each but explain what may be the same or different. Be as specific as you can be in your response.
1.(-2)^2
2.-2^2
3. -(2)^2
Answer:
1. 4
2. -4
3. -4
Step-by-step explanation:
Let's look carefully at each problem and explain it.
1. (-2)^2
This means find the square of the number -2. Since the square of a number means multiplying the number by itself, then
(-2)^2 means the product (-2) * (-2),
and since the product of two negative numbers is positive, then
(-2)^2 = (-2) * (-2) = 4
Answer is 4.
2. -2^2
Here, the exponent applies only to the 2, not to -2. This problem means square 2 and then take the opposite of the product. This can be written as
-(2^2)
-2^2 = -(2^2) = -(2 * 2) = -(4) = -4
Answer is -4.
3. -(2)^2
This is the same as problem 2 above. You square the 2 first, then take its negative.
-(2)^2 = -(2^2) = -(2 * 2) = -(4) = -4
Answer is -4

Determine the value of z in the figure answers: z = 40° z = 90° z = 20° z = 45°
Answer:
20 degreesStep-by-step explanation:
This is a linear pair, whose sum always equals 180 degrees,
hence, we can set up the equation:
2z+140=180
2z=180-140
2z=40
z=40/2
z=20
Thus, the answer is 20 degrees
Answer:
z = 20°
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
2z+ 140 = 180
Subtract 140 from each side
2z+140-140 = 180-140
2z = 40
Divide by 2
2z/2 = 40/2
z = 20

Enter the ordered pair that is the solution to the system of equations graphed below y = - 1/2 * x - 1 y = - 3x + 9
Answer:
x= 4 and y =-3
Step-by-step explanation:
To find the pair that is the solution to the system of equations, we will follow the steps below;
y = -1/2 x - 1 -----------------------------------------------------------------------------------(1)
y = -3x + 9 ---------------------------------------------------------------------------------------(2)
substitute equation (1) in equation (2)
-1/2 x - 1 = -3x + 9
collect like term
-[tex]\frac{1}{2}X[/tex] + 3x = 9 + 1
-x+ 6x /2 = 10
5x /2 = 10
multiply both-side of the equation by 2
5x = 20
Divide both-side of the equation by 5
x = 4
substitute x = 4 into equation (2)
y = -3x + 9
y = -3(4) + 9
y = -12 + 9
y = -3
The solution is
x= 4 and y =-3

a triangular path in the neighborhood park. The
sides of the path measure 3.36 miles, 4.18 miles, and 5.61 miles. How far
does Peter ride?
Answer:
The distance that Peter rides is:
13.15 miles.Step-by-step explanation:
To identify the miles that Peter rides, you must imagine the triangle with measures: 3.36 miles, 4.18 miles, and 5.61 miles. How you can suppose, Peter regularly rides exactly by each side of the triangle mentioned, then you must find the perimeter of the triangle to identify the miles that Peter rides, remember that the perimeter of an irregular triangle is:
Perimeter of a triangle = side + side + sideIf you replace the formula, you obtain:
Perimeter of a triangle = 3.36 miles + 4.18 miles + 5.61 miles Perimeter of a triangle = 13.15 milesIf two-thirds of a number is five-thirds more than the number, what is the number?
