Answer: x=68 °
Step-by-step explanation:
The sum of the angles h in the n-gon is calculated by the formula :
[tex]\displaystyle \rm S=180(n-2)[/tex]
where n is the number of sides
Then the sum of all the corners of the pentagon is equal to
[tex]\rm S=180(5-2)=540 \\\\[/tex]
[tex]\displaystyle x+(x+60)+(x+80)+(x+40)+(x+20)=540 \\\\ 5x+200=540 \\\\ 5x=340 \\\\ \boxed{x=68^{\circ}}[/tex]
Its a Pentagon
[tex]\\ \sf\longmapsto x+x+60+x+40+x+80+x+20=540[/tex]
[tex]\\ \sf\longmapsto 5x+200=540[/tex]
[tex]\\ \sf\longmapsto 5x=540-200[/tex]
[tex]\\ \sf\longmapsto 5x=340[/tex]
[tex]\\ \sf\longmapsto x=340/5[/tex]
[tex]\\ \sf\longmapsto x=68[/tex]

Find an expression which represents the difference when (-9x +9) is subtracted
from (x + 8) in simplest terms.
Answers
Answer:
10x - 1
Step-by-step explanation:
(x + 8) - (-9x + 9) = x + 8 + 9x - 9 = (x+9x) + (8-9) = 10x -1
The equivalent Expression is (10x- 1).
What is Expression?An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it.
For example, A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression.
Given:
We have to find the difference when (-9x +9) is subtracted from (x + 8)
so, (x + 8) - (-9x + 9)
= x + 8 + 9x - 9
= (x+9x) + (8-9)
= 10x -1
Hence, the equivalent Expression is (10x- 1).

Solve the equation a = m - n for the variable n.
Answers
Answer:
n = m - a
Step-by-step explanation:
a = m - n
add n to both sides of the equation
a + n = m - n + n
a + n = m
subtract a from both sides of the equation
a - a + n = m - a
n = m - a
Answer:
n = a - m
Step-by-step explanation:
a = m - n
a - m = n

Answers
Answer:
[tex]x = \frac{1}{28} y^{2}[/tex]
Step-by-step explanation:
parabola equation with vertex (0 , 0) and focus length |f| = 7

What is the equation in point slope form for a linear function with a slope of m = -4 that passes through the
point (2,- 7)?
Answers
The equation for point slope form is
y - y1 = m(x - x1) where m represents the slope.
It coordinates and slope are given, they just need to be plugged into the equation.
y - (-7) = -4(x - 2)
Subtracting a negative can be written as adding a positive, so the equation can be simplified as:
y + 7 = -4(x - 2)

Math
Answers
Answer: If you measure out a 10k course and then time how long it takes you to ride it, that will tell you which speed range to use and what time to input. If you weigh 185 pounds and fall into the 12 to 13 mph range, it will take you about 30 minutes to pedal 10k — which means that according to the ACE estimates, you will burn about 335 calories.
Step-by-step explanation:
Hope this helps!
Answer:
0.2km/min or 12.7km/hour
Step-by-step explanation:
speed = distance ÷ time
speed = (10km + 8km) ÷ (45 mins + 40 mins)
= 18 ÷ 85
= 0.21176...km/min ≈ 0.2km/min
To convert 0.21176...km/min into km/hr, you multiply by 60
0.21176...km/min × 60 = 12.70588...km/hr ≈ 12.7km/hr

According to the Rational Root Theorem, which statement about f(x)=8x3−4x2+6x+3 is true?
Group of answer choices
Any rational root of f(x) is a multiple of 8 divided by a multiple of 3.
Any rational root of f(x) is a factor of 8 divided by a factor of 3.
Any rational root of f(x) is a multiple of 3 divided by a multiple of 8.
Any rational root of f(x) is a factor of 3 divided by a factor of 8.
Answers
The rational root theorem is used to determine the possible roots of a function.
The true statement is: (d) Any rational root of f(x) is a factor of 3 divided by a factor of 8.
The function is given as:
[tex]\mathbf{f(x) = 8x^3 - 4x^2 + 6x + 3}[/tex]
The possible roots of a function
[tex]\mathbf{f(x) = qx^n + ax^{n-1} +.....+ p}[/tex]
are
[tex]\mathbf{Roots = \pm\frac{Factors\ of\ p}{Factors\ of\ q}}[/tex]
By comparison: p = 3 and q = 8
So, we have:
[tex]\mathbf{Roots = \pm\frac{Factors\ of\ 3}{Factors\ of\ 8}}[/tex]
Hence, the true option is (d) Any rational root of f(x) is a factor of 3 divided by a factor of 8.

Answers
Answer:
The population will be 334,958.
Step-by-step explanation:
Multiply 338,000 by 0.009 to get the answer. The reason is to multiply by a percentage, you move the decimal two spots to the left. For example, 0.9 -> 0.009. Another would be 3 -> 0.03.

Answer:
[tex]\displaystyle y = -\frac{2}{3} x + \frac{34}{3} \text{ or } 2x + 3y =34[/tex]
Step-by-step explanation:
We want to find the equation of a line that contains the point (5, 8) and is parallel to the graph of:
[tex]\displaystyle 2x + 3y = 9[/tex]
Recall that parallel lines have equal slopes.
Find the slope of the given graph by rewriting it in slope-intercept form:
[tex]\displaystyle \begin{aligned} 2x + 3y & = 9 \\ \\ 3y & = -2x + 9 \\ \\ y & = -\frac{2}{3} x + 3 \end{aligned}[/tex]
Hence, the slope of the given graph is -2/3. Therefore, the slope of our new line must also be -2/3.
Since we now have a slope and a point, we can consider using the point-slope form:
[tex]\displaystyle y - y_1 = m(x-x_1)[/tex]
Substitution yields:
[tex]\displaystyle y - (8) = -\frac{2}{3}(x -( 5))[/tex]
We can simplify this into slope-intercept form:
[tex]\displaystyle \begin{aligned} y - 8 & = -\frac{2}{3} x + \frac{10}{3} \\ \\ y & = -\frac{2}{3} x + \frac{34}{3}\end{aligned}[/tex]
Or, into standard form:
[tex]\displaystyle \begin{aligned} y & = -\frac{2}{3}x + \frac{34}{3} \\ \\ 3y & = -2x + 34 \\ \\ 2x + 3y & = 34 \end{aligned}[/tex]
