What is permutation?Permutation is simply used it illustrate the number of ways for a given information. The formula is illustrated as:
n! / (n – r)!
N is the number of things you are choosing from,
r is the number of items.
“!” is a factorial of a number
Since the delivery truck has 4 stops to make in a neighborhood, the sequences of stops will be:
= n! / (n – r)!
= 4!

Starting at midnight, Aarf the Dog barks for 15 seconds and
then is silent for the next 25 seconds. Aarf the Dog continues
this bark-fest until 1:01 AM that same morning. How many
times did Aarf the Dog bark for 15 seconds?
The number of times Aarf the Dog bark for 15 seconds if the dog starts barking at midnight and stops at 1:01 AM is 91.5 times
What is the number of times Aarf the Dog bark for 15 seconds?Time Aarf dog barks = 15 secondsTime Aarf dog become silent = 25 secondsTotal time of barking and silence = 15 seconds + 25 seconds
= 40 seconds
Time Aarf dog starts barking = 12:00 amTime Aarf dog stops barking = 1:01 AMDifference in time = 1:01 AM - 12:00 am
= 1 hour 1 minutes
Convert hours and minutes to seconds
1 hour = 60 minutes1 minutes = 60 seconds1 hour 1 minutes = 61 minutes × 60 seconds
= 3,660 seconds
Number of times Aarf the Dog bark for 15 seconds = Total hours Aarf dog barks / Total time of barking and silence
= 3,660 / 40
= 91.5 times
So therefore, the number of Aarf the Dog bark for 15 seconds is 91.5 times

Given: DEFG is a trapezoid DE=FG, DF=a, m∠FDG=45° Find: Area of DEFG
Answer:
DEFG = (1/2)a^2
Step-by-step explanation:
tells us ∠FDG = 45° and ∠EGD = 45° and by corresponding angles related to parallel lines ∠FBD = 45°. Then ∠DFB = 90°!
So DFB- (1/2)(DF)(FB)=(1/2)a2
The total measure of two adjacent angles is 153°. if one of the adjacent angles measures 104.7°, determine the measure of the other adjacent angle. 194.7° 257.7° 48.3° 75.3°
One of the unknown adjacent angle measures 48.3 degrees.
The adjacent angles are next to each other and hence are calculated by performing addition of the constituent angles. Let us assume the unknown adjacent angle be x.
Forming the equation based on x, adjacent angles and it's sum
104.7 + x = 153
Rewriting the equation as per the x
x = 153 - 104.7
Performing subtraction on Right Hand Side of the equation to find the value of x
x = 48.3 degrees
Thus, the measure of the adjacent angle is 48.3 degrees.

In a certain chemical the ratio of zinc to copper is 4 to 11. a jar of the chemical contains 484 grams of copper. how many grams of zinc does it contain
The jar of chemicals contains 176 grams of zinc.
Using ratio and proportion to calculate the amount of zinc. Let us assume the mass of zinc to be x. Equating the ratios.
4 : 11 = x : 484
Rewriting the equation in terms of x
x = (484 × 4) ÷ 11
Performing multiplication in numerator on Right Hand Side of the equation to find the value of x
x = 1936 ÷ 11

Show that a sum of the angles of a polygon could be 1800 and not 2000
Answer:
150
Step-by-step explanation:
The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides. The problem concerns a polygon with twelve sides, so we will let n = 12. The sum of the interior angles in this polygon would be 180(12 – 2) = 180(10) = 1800.

What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have the following problem -
The distance y (in miles) that train A travels in [x] amount of time is represented by the equality y = 78x. The graph shows the distance that train B travels.
Train A is moving with speed s[A] = 78 miles/hour {As slope of the equation is 78}. The train B will move with speed given by -
s[B] = (132 - 66)/(2 - 1) = 66 miles/hour

Y intercept = -1 and goes through the point (3,8)
The equation of a line for y-intercept and the coordinate point is y=3x-1.
Given that, y-intercept is -1 and the line passes through the point (3, 8).
What is a y-intercept?In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
Put, c=-1 and (x, y)=(3, 8) in y = mx+c, we get
8=m(3)-1
⇒ 3m=9
⇒ m=3
Substitute c=-1 and m=3 in y = mx+c, we get
y=3x-1

C. y=x^2+2x+1
2x+y=2
D. y=x^2-2x+1
2x-y=2
y = x²-2x+1, 2x-y=2 is the system of equations represented by the graph
How to determine the system of equations represented by the graph?
By examining the graph, you will notice that the straight and the curve meet at (3,4) and (1,0) as indicated. The x values of these points of intersection give the solution of the system. Thus:
We have x = 3 and x = 1
These values can be used to form the equation of the system. Thus:
(x-3)(x-1) = 0 (Clear the parenthesis)
x² -x-3x +3 = 0
x² -4x +3 = 0
Next, we are going to check for the option that gives the x² -4x +3 = 0
Given: y = x²-2x+1, 2x-y=2
Rewrite 2x-y=2 to be in form y: y =2x-2
We now have y = x²-2x+1 and y =2x-2
Equate the two y: x²-2x+1 =2x-2
x²-2x+1 -2x+2 = 0
x²- 4x+ 3 = 0
Since y = x²-2x+1, 2x-y=2 gives the same equation, therefore, the system of equations represented by the graph is y = x²-2x+1, 2x-y=2. So option D is the answer
