Answer:
∠ CDE = 134°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 6 , then
sum = 180° × 4 = 720°
let ∠ BCD = x then ∠ CDE = 2x
sum the angles and equate to 720
121 + 144 + 129 + 125 + x + 2x = 720 , that is
519 + 3x = 720 ( subtract 519 from both sides )
3x = 201 ( divide both sides by 3 )
x = 67
Then
∠ CDE = 2x = 2 × 67 = 134°

Suppose a math class starts at the beginning of the school year with 12 boys and 8 girls. However, after school resumed in January, 6 new boys and 4 new girls came to the class. Is the ratio of boys to the total number of students in the class still the same?
Answers
Answer:
yes the ratio is the same
Step-by-step explanation:
12/8 = 3/2 (divided the top and bottom by 4)
6/4 = 3/2 (divided the top and bottom by 2)
yes the ratio is the same
Answer:
To compare, first find out what the ratio of boys to students is at the beginning of the school year: 12/8 or, in the simplest form, 3/2.Once school resumes in January, that ratio becomes 18/12 - (12 + 6)/(8 + 4) - or 3/2 in simplest form.Therefore, the ratio is still the same.

jenny is drafting a paper on her computer. she leaves a right margin that is one-fifth the width of the page for later editing marks. on the

Answers
The area of the drafting section on the screen after Jenny left a right margin for editing marks is 1,077,120 pixels.
What is the area of the drafting section?The first step is to determine the dimensions of the drafting section:
Length = 11 inches
Width = (1 - 1/5) x 8.5 = 6.8 inches
The second step is to convert the dimensions to pixels:
Length = 11 inches x 120 = 1320
Width = 6,8 inches x 120 = 816
Area = 1320 x 816 = 1,077,120 pixels

[tex]\rightarrow \dfrac{\text{Sum of digits}}{\text{Total digits}} = \text{Mean}[/tex]
[tex]\rightarrow \dfrac{\text{Sum of digits}}{\text{Total digits}} = 39[/tex] [Mean = 39]
[tex]\rightarrow \dfrac{25 + p}{\text{Total digits}} = 39[/tex] [Sum of digits = 25 + p]
[tex]\rightarrow \dfrac{25 + p}{5} = 39[/tex] [Total digits = 5]
Step-by step calculations:
Use cross multiplication:

Simplify the RHS:
[tex]\rightarrow 25 + p= 39 \times 5[/tex]

SOLVE THE SIMULTANEOUS EQUATION
3y=6x+3 and 3y=4x+6
Answers
Answer:
x=3/2
y=4
Step-by-step explanation:
3y=6x+3
3y=4x+6
we see that 3y=3y so even the right side of the equations are equal.
6x+3=4x+6
6x-4x=6-3
2x=3
x=3/2
so easily we find y
we found that x=3/2 so
3y=6*(3/2)+3=9+3=12
y=12/3=4
so the solution of simultaneous equation is
x=3/2
y=4

The solutions to the equation sin(x + pi/2) = 1/2 in the interval [3pi/2, 2pi] are x = 5pi/3 and x = 4pi/3.
What is trigonometry?
Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles.
We can solve this equation using the following steps:
Subtract pi/2 from both sides to get sin(x) = 1/2.
Recall that the sine function is positive in the first and second quadrants.
Therefore, we need to find the angles in these quadrants where sin(x) = 1/2.
The two angles in the first quadrant where sin(x) = 1/2 are pi/6 and 5pi/6. The two angles in the second quadrant where sin(x) = 1/2 are 7pi/6 and 11pi/6.
Adding pi/2 to each of these angles gives the solutions to the original equation. These solutions are:
x = pi/6 + pi/2 = 2pi/3
x = 5pi/6 + pi/2 = 7pi/6
x = 7pi/6 + pi/2 = 5pi/3
x = 11pi/6 + pi/2 = 4pi/3
We now need to check which of these solutions lie in the interval [3pi/2, 2pi]. We find that the solutions in this interval are:
x = 5pi/3
x = 4pi/3
Therefore, the solutions to the equation sin(x + pi/2) = 1/2 in the interval [3pi/2, 2pi] are x = 5pi/3 and x = 4pi/3.
