What is the area of a rectangle?

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

[tex]A=a\times b[/tex]

Here, (a)is the length of rectangle and (b) is the width of the rectangle.

A rectangle with constant area has possible lengths and widths as shown in the table below.

Width vs. Length of a rectangle

width (w) 2 4 6 8length (l) 37.5 18.75 12.5 9.375

In the above table, the length of a rectangle is decreasing with increasing the width of a rectangle.

For such relation, the value of w should be inversely proportional to the length of it. The first option given as,

[tex]I=\dfrac{k}{w}[/tex]

Here l is the length, w is the width, and k is a constant (w not-equals 0).

In this expression, the length of the rectangle is inversely proportional to the width of the rectangle.

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

Answer:

p = 170

Setting up the formula:

The mean is the sum of the digits divided by the total digits in the set.

[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:

[tex]\rightarrow 25 + p= 39 \times 5[/tex]

Simplify the RHS:

[tex]\rightarrow 25 + p= 39 \times 5[/tex]

[tex]\rightarrow 25 + p= 195[/tex]

Subtract 25 both sides:

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

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.

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

Which option above can be written as a geometric sequence?
A. Option 1
B. Option 2
C. Both Option 1 and 2
D. Neither Option 1 or 2

Answers

Answer:

B. Option 2 (only)

Step-by-step explanation:

A geometric sequence is a sequence of terms that have a common ratio.

Option 1

The deposits are ...

100, 50, 50, 50, ...

The ratios of terms of this sequence are ...

1/2, 1, 1, 1

So, the ratio is not constant, and the sequence is not geometric.

Option 2

The deposits are ...

5, 10, 20, 40, ...

The ratios of terms of this sequence are ...

10/5 = 2, 20/10 = 2, 40/20 = 2, ...

The ratio is constant, so the sequence of deposits for Option 2 is geometric.
