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
computer, each inch is equivalent to the length of 120 pixels. what is the area of the drafting section on the screen?
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

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.

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

Point W(-4, 7) was translated as follows: W(-4, 7) – W'(-2, 4). A student wrote the algebraic rule to describe the
translation as (x,y) → (x-3.y+2). Evaluate the student's answer.
A. Incorrect; the student should add 2 to the x-coordinate and subtract 3 from the y-coordinate.
B. Incorrect; the student should add-4 +-2 to calculate the x-coordinate and add 7 + 4 to calculate
the y-coordinate.
C. Incorrect; the student should add 3 to the x-coordinate and subtract 2 from the y-coordinate.
D. The student's answer is correct.
Answers
Answer:
A
Step-by-step explanation:
W (- 4, 7 ) → W' (- 2, 4 )
- 4 → - 2 in the x- directions is a shift of + 2
7 → 4 in the y- direction is a shift of - 3
then translation rule should be

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.

First we have to solve them to make it easier to compare them.
So...
[tex]-3(-2)+3=9\\3(-4)+9=-3[/tex]
Now we now that the first one is 9 and the second one is -3. So obviously the positive number has to be greater than the negative number, so....
[tex]9>-3[/tex]
Answer:
-3(-2)+3 is greater than 3(-4)+9.
Step-by-step explanation:
First, we have to solve.
1) -3(-2)+3 Solve left to right. -3(-2)=6
6+3 Add. 6+3=9
9
2) 3(-4)+9 Solve left to right. 3(-4)=-12
-12+9 Add. -12+9=-3
-3
9 is greater than 3. So, -3(-2)+3 is greater than 3(-4)+9.
