Answer:
x = 88.333
Step-by-step explanation:
Octagon = 1080 degrees
1080 = 2x + x + 143 + 152 + 116 + 125 + 140 + 139 (Clean up the problem)
1080 - 815 = 3x
265 = 3x (Divide each side by 3)

x=180-27-63=90....in triangle mon
Answer:
y=27, x=80

Determine whether the given value is a solution of the equation.
b
6; b =78
13
78 (select) a solution.
is 78 the solution or not
Answer:
78 is a solution
Step-by-step explanation:
The given equation is b/13 = 6
Therefore, by applying the multiplication property of equality, we have by multiplying both sides by 13, we have;
b/13 × 13 = 6 × 13
The 13 in the denominator of b/13 divides the 13 in the multiplicand to give 1, and we get the following equation
b/13 × 13 = b × 1
Therefore;
b/13 × 13 = b × 1 = 6 × 13 = 78
b × 1 = 78
By the multiplicative identity property of '1', we get;
b × 1 = 1 × b = b
∴ b × 1 = b = 78
b = 78
∴ 78 is a solution of the equation.

Find the equation of the line through point (−2,−1) and perpendicular to 5x+6y=−6.
Step-by-step explanation:
When lines are perpendicular to each other
multiplying their gradients(m) will equal to - 1
so , m1 × m2 = -1
1st:Find m1
5x+6y= -6
make y the subject,
6y= -5x -6
[tex]y = \frac{ - 5x - 6}{6} [/tex]
y= -5/6x - 1
because y = mx + c
m1 = -5/6
2nd:find m2
-5/6 × m2 = -1
m2 = 6/5
3rd: substitute m2 and the coordinates into y=mx+c
y=mx+c
-1= (6/5)(-2)+c
-1 = -12/5 + c
-5 = -12 + c
-5+12= c
c = 7
4th: substitute m2 and c into y= mx+c to find the equation the line
y =6/5x + 7 (Ans)
As per slope-intercept form, the equation of the line through point (−2,−1) and perpendicular to 5x + 6y = -6 is 5y = 6x + 7.
What is the slope-intercept form of a straight line?The slope-intercept form of a straight line is y = mx + c.
Here, 'm' is the slope and 'c' ix the y-intercept of the given line.
The given equation is 5x + 6y = - 6
Therefore, in slope-intercept form, this equation will be:
y = - 5x/6 - 1
Therefore, the slope of this line is m = - 5/6 and the y-intercept is c = - 1.
The required line is perpendicular to the given line.
Therefore, the slope of the required line is
= - 1/m
= 6/5
Again, the required line passes through the point (- 2, - 1).
Therefore, - 1 = - 2(6/5) + c
⇒ c = - 1 + 12/5
⇒ c = 7/5
The equation of the required line is
y = (6/5)x + 7/5
⇒ 5y = 6x + 7

What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
The collection includes all locations on the surface of the shape (x, f(x)) that make up a function of f's graph. We may alternatively say that the graph of f is the curve of y = f. (x). As a result, the diagram of an equation is a particular instance of the graphs of functions.

Calculate the measures of spread for Mrs Hampton's class data. Justify your
response by describing the process used to find each measure, (2 points)
The measures of spread include the range, quartiles and the interquartile range, variance and standard deviation. Let's consider each one by one.
Interquartile Range:
Given the Data -> First Quartile = 2, Third Quartile = 5
Interquartile Range = 5 - 2 = 3
Range: 8 - 1 = 7
Variance:
We start by determining the mean,
[tex]\:1+\:2+\:3+\:3+\:3+\:5+\:8 / 7 = 3.57[/tex]
n = number of numbers in the set
Solving for the sum of squares is a long process, so I will skip over that portion and go right into solving for the variance.
[tex]\sum _{i=1}^n\frac{\left(x_i-\bar{x}\right)^2}{n-1},\\\\=> SS/n - 1\\\\=> 31.714/7 - 1\\=> 5.28571[/tex]
5.3
Standard Deviation
We take the square root of the variance,
[tex]\sqrt{5.28571} = 2.29906[/tex]
2.3
If you are not familiar with variance and standard deviation, just leave it.

If, on their own, it takes 6 hours for Person A to complete a task and 9 hours for Person B to complete the same task, then how many hours would it take if they worked together? Estimate your answer to 4 places after the decimal, if necessary.
Answer:
Step-by-step explanation:
A does 1/6 of the task per hour.
B does 1/9 of the task per hour.
Together, they do 1/6+1/9 = 5/18 of the task per hour, finishing in 18/5 hours.
18/5 = 3.6 hours
A wildlife photographer photographs a crocodile and then paddles against a river current for 6 km. Then, hoping to photograph a hippopotamus, she paddles 15 km across a lake. She paddles across the lake for one hour longer than she paddled up the river. Find the speed of the boat as she paddles if the river current is 2 km/h (2 answers)
Answer:
Step-by-step explanation:
5 km/h or 6 km/h
Step-by-step explanation:
Let the speed of the boat be x
Speed against the current in the river is x - 2
Time in the river:
6/(x - 2)
Time in the lake:
15/x
The difference:
6/(x - 2) = 15/x - 1
Solve for x to find the speed of the boat
Multiply both sides by x(x - 2) to clear the fraction:
6x = 15(x - 2) - x(x - 2)
6x = 15x - 30 - x² + 2x
x² - 11x + 30 = 0
(x - 5)(x - 6) =0
x -5 = 0, x - 6 = 0
x = 5 km/h, x = 6 km/h
