The sum of the angle measures of a quadrilateral is 360°. Write and solve an equation to find the value of X.
Answer:
1). x° + 100° + 120° + 100° = 360°
2). x = 40
Step-by-step explanation:
Formula for the sum of the interior angles of a polygon = [tex](n-2)\times 180[/tex]
Where n = number of sides of the polygon
From the picture attached,
For n = 4,
Sum of the interior angles of the given polygon = (4 - 2) × 180°
= 360°
Therefore, equation for the sum of interior angles will be,
x° + 100° + 120° + 100° = 360°
x° + 320° = 360°
x° = 360° - 320°
x° = 40°

The amount of algae in a bloom, P, can be modeled by the equation P = t^4 + 6t^3+ 7t^2 + 8t, where t is measured in weeks. During what interval of t will the population of algae be greater than 500?
(−∞, −6.759) ∪ (3.452, ∞)
(6.759, 3.452)
(0.3452, ∞)
(0, 3.452)
Answer:
C. (0.3452, ∞)
Step-by-step explanation:
The interval of t when the population of algae will be greater than 500 is (3.452, ∞)
What is an equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
The amount of algae in a bloom, P, can be modeled by the equation [tex]P = t^4 + 6t^3+ 7t^2 + 8t[/tex] where t is measured in weeks.
We need to find the find the interval of t will the population of algae be greater than 500
So, we get an inequality,
[tex]\Rightarrow P > 500\\\\\Rightarrow t^4 + 6t^3+ 7t^2 + 8t > 500\\\\\Rightarrow t (t^3 + 6 t^2 + 7 t + 8) > 500\\\\\Rightarrow t [t [t (t + 6) + 7] + 8] > 500\\\\\Rightarrow t > 3.45~~and ~~t < -6.759\\\\[/tex]
But time is measured in weeks.
So, t will not have the values from the interval (−∞, −6.759)
Therefore, the interval of t when the population of algae will be greater than 500 is (3.452, ∞)

Solve the equation for x. As you solve, justify the steps. Please help me out. -(3x - 12) = 9x - 4
Answer:
[tex]x=\frac{4}{3}[/tex]
Step-by-step explanation:
[tex]-\left(3x-12\right)=9x-4[/tex]
Distribute the negative sign to both 3x and -12:
[tex]-\left(3x\right)-\left(-12\right)=9x-4[/tex]
Remove brackets: (Double negative = Positive)
[tex]-3x+12=9x-4[/tex]
Subtract 12 from both sides:
[tex]-3x+12-12=9x-4-12[/tex]
[tex]-3x=9x-16[/tex]
Subtract 9x from both sides:
[tex]-3x-9x=9x-16-9x[/tex]
[tex]-12x=-16[/tex]
Divide both sides by -12:
[tex]\frac{-12x}{-12}=\frac{-16}{-12}[/tex]

Quadrilateral RAPS is located at the vertices
R(-4,1), A(-3, 4), P(0,5), S(-1,1). Where will points
R", A", P", S", be located after the quadrilateral has been reflected
across the line y - x and then rotated 180° about the origin?
Answer:
R''(-1, 4), A''(-4, 3), P''(-5, 0), S''(-1, 1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new position. Types of transformation include dilation, reflection, translation and rotation.
If a point A(x, y) is reflected over the line y = x, the new point is at A'(y, x)
If a point A(x, y) is rotated 180° clockwise about the origin, the new location is at A'(-x, -y)
Since Quadrilateral RAPS is located at the vertices R(-4,1), A(-3, 4), P(0,5), S(-1,1), After been reflected across the line y = x, the new locations are at:
R'(1, -4), A'(4, -3), P'(5, 0), S'(1, -1)
Then the rotation of the points R'(1, -4), A'(4, -3), P'(5, 0), S'(1, -1) 180° about the origin gives:
R''(-1, 4), A''(-4, 3), P''(-5, 0), S''(-1, 1)
3(-3x - 3) + 2x + 4 = -33

A)Finding the least common denominator.
B)Reducing the fractions.
C)Adding the numerators, but keeping the denominators.
D)Adding the denominators, but keeping the numerators.
Answer:
(A) Finding the least common denominator.
In order to add the fractions 2/3 + 4/5 the least common factor of 3 and 5 has been taken in the first step thus,option (A) is correct.
What is the lowest common multiple?The lowest common multiple is the smallest multiple which is common between any two numbers.
It means we can divide both numbers by that and that is the smallest number by which both dived.
For example, LCM of 2 and 8 is 8.
As per the given two fractions,
2/3 + 4/5,
The least common factor of 3 and 5 is 15
Thus, (10 + 12)/15
Thus, in the first step, we have taken LCM.
Hence "In order to add the fractions 2/3 + 4/5 the least common factor of 3 and 5 has been taken in the first step".

The measure of an angle is 10 degrees more than its supplement. What is the measure of
the smaller angle?
Supplementary angles are angles that add up to 180 degrees.
Angle 1 = x
Angle 2 = x + 10
Since they are supplementary, we can set then equal to 180
x + x + 10 = 180
Combine like terms
2x + 10 = 180
Subtract 10 from both sides
2x = 170
Divide both sides by 2
x = 85
Angle 1 = 85 degrees
Angle 2 = 85 + 10 = 95 degrees
