Answer:

Answer

3.0/5

8

1cm = 50

2 cm = 50 x 2

3cm = 50 x 3

and the inverse:50m = 50/50 = 1cm

100m = 100/50 = 2cm

150m = 150/50 = 3cm

381m = 381/

The height in centimeters of Micah's model given the scale of the drawing is 7.62cm

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

Scale of the drawing = original dimensions / dimensions of the scale drawing

The height of the model = 381 / 50 = 7,62cm

A = 20 x 10

A = 200 in.^2

Note: ^2 after in. means squared for area.

The area of the triangle that Janelle cut out of the poster board is:

A = 1/2bh

A = 1/2 x 10 x 9

A = 90/2

A = 45 in.^2

The area of the poster board that she has left is: 200 - 45 = 155 in.^2

Answer: 155 in.

The area of the poster board that she has left is,

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Now, The area of the parallelogram is,

⇒ Area of Parallelogram:

A= base × height

A= 20 in × 10 in

A= 200 in²

And, Area of Triangle:

A= 1/2 base * height

A= 1/2 (10 in)(9 in)

A= 1/2 (90)

A= 45 in²

Thus, The Area of Poster Left is,

A= Parallelogram Area - Triangle Area

A= 200 in² - 45 in²

A= 155 in²

Thus, 155 in² is the area of the poster board she has left.

Answer:

x=35

Step-by-step explanation:

ANSWER

x=35°

EXPLANATION

We want to find the value of x, when

[tex] \cos(x) = \sin(20 + x) \degree[/tex]

and 0°<x<90°

Recall that the sine and cosine are complementary trigonometric ratios.

Hence cos x = sin (90-x)

Our equation now, becomes;

[tex] \sin(90 - x) \degree= \sin(20 + x) \degree[/tex]

We now equate the argument to get,

[tex]90 - x=20 + x[/tex]

Group similar terms to obtain:

[tex]90 - 20 = x + x[/tex]

[tex]70 = 2x[/tex]

This implies that,

[tex]x = 35 \degree[/tex]

A linear equation is an equation in which each term has at max one degree. The correct option is B.

A linear equation is an equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c

Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.

The total deposit and rent collected by an apartment manager for one resident are given by the equation t = 350 + 700m, where m is the number of months the resident has lived there. Since the equation is in the form of a linear equation it can be concluded that the model is linear.

Comparing the equation with a linear equation,

t = 350 + 700m

y = C + mx

The slope of the equation is 700, while the y-intercept is 300.

Two boxes contains the following pieces of chalk of the same size.

Red = 2

Yellow = 1

Green = 4

White = 3

Each box contains = 2 + 1 + 4 + 3 + 2  = 12 pieces of chalk of the same size.

There are total pieces of chalks are 12 and white chalks are 3 in each box.

If one piece of chalk will be randomly selected from each box.

Answer:

y = 2x + 4

slope: 2

y-intercept: (0,4)

Step-by-step explanation:

to find the slope and y-intercept of the two points, we can use the following formula:

y2 - y1/ x2 - x1 = slope

to solve, we plug in the values into the equation

we will treat (0,4) as x1, y1 and (7,18) as x2, y2

y2 - y1 = 18 - 4 = 14

x2 - x1 = 7 - 0 = 7

14/7 is the slope, but we can simplify as 14/7 is equal to 2

so the slope is 2 (can also be said as 2/1)

we can now put the following slope into slope-intercept form (y=mx+b)

y = 2x + b < b is the slope, we so we need to solve for b

looking at our points (0,4) and (7,18), we see that we have the y-intercept, as the y-intercept has the x-coordinate 0, and any y-coordinate. the y-intercept is (0,4)

but if we dont have the y-intercept that easily, we can plug in any coordinate that we are given into the equation and solve for b. for this example, ill use (0,4) to plug into the equation

4 = 2(0) + b

4 = b

the y-intercept is 4

the final equation would be the following:

y = 2x + 4

The equation of the line that passes through two points (0, 4) and (7, 18) is y = 2x + 4.

To determine the equation of the line using the given information, we first need to find the slope and y-intercept. The slope of a line can be calculated using the formula:

slope (m) = (change in y-coordinates) / (change in x-coordinates)

Using the points (0, 4) and (7, 18), we can calculate the slope:

slope (m) = (18 - 4) / (7 - 0) = 14 / 7 = 2

So, the slope of the line is 2.

Next, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept. To find the y-intercept, we can substitute one of the points into the equation and solve for b.

Using the point (0, 4):

4 = 2(0) + b

b = 4

Therefore, the y-intercept (b) is 4.

Finally, we can write the equation of the line:

y = 2x + 4

Answer:

(x,y) = (-6.12,-11.76)

Step-by-step explanation:

2x+4y=-48 => eq(i)

4x-9y=57  => eq(ii)

We need to solve these equations simultaneously to find the values of x and y.

Multiplying eq(i) with 2 and subtracting both equations

4x + 16y = -96

4x - 9y  = 57

-    +         -

__________

25 y = -153

y = -153/25

y = -6.12

Putting value of y in eq(i)

2x + 4(-6.12) = - 48

2x - 24.48 = -48

2x = -48 + 24.48

2x = -23.52

x= -23.52/2

x= -11.76

So, values of x and y are -6.12 and -11.76

(x,y) = (-6.12,-11.76)

The solution to the system of linear equations is [tex]\(x = -6\) and \(y = -9\).[/tex]

Let's solve the system of linear equations:

[tex]1. \(2x + 4y = -48\)\\2. \(4x - 9y = 57\)[/tex]

We can use the substitution or elimination method. I'll use the elimination method here:

Multiply the first equation by 2 to make the coefficients of [tex]\(x\)[/tex]in both equations the same:

[tex]1. \(4x + 8y = -96\)\\2. \(4x - 9y = 57\)[/tex]

Now, subtract the second equation from the first to eliminate [tex]\(x\):[/tex]

[tex]\((4x + 8y) - (4x - 9y) = -96 - 57\)[/tex]

Simplify:

[tex]\(17y = -153\)[/tex]

Now, solve for \(y\):

[tex]\(y = -\frac{153}{17} = -9\)[/tex]

Now that we have \(y\), substitute it back into one of the original equations. I'll use the first equation:

[tex]\(2x + 4(-9) = -48\)[/tex]

Simplify:

[tex]\(2x - 36 = -48\)[/tex]

Add 36 to both sides:

[tex]\(2x = -12\)[/tex]

Divide by 2:

[tex]\(x = -6\)[/tex]

So, the solution to the system of linear equations is [tex]\(x = -6\) and \(y = -9\).[/tex]

Answer:

Step-by-step explanation:

We have the expression:

To simplify the expression multiply by the conjugate of the denominator.

The denominator is

[tex]\sqrt{3}-\sqrt{2}[/tex]

Then its conjugate is:

[tex]\sqrt{3}+\sqrt{2}[/tex]

Then:

[tex]\frac{2\sqrt{2}}{\sqrt{3}-\sqrt{2}}*\frac{\sqrt{3}+\sqrt{2}}{\sqrt{3}+\sqrt{2}}\\\\=\frac{2\sqrt{2}\sqrt{3}+2\sqrt{2}\sqrt{2}}{(\sqrt{3})^2-(\sqrt{2})^2}\\\\\frac{2\sqrt{6}+4}{3-2}}\\\\= \frac{2\sqrt{6}+4}{1}}=2\sqrt{6}+4[/tex]

Answer:

[tex]4+2\sqrt{6}[/tex]

Step-by-step explanation:

Given expression is [tex]\frac{2\sqrt{2}}{\sqrt{3}-\sqrt{2}}[/tex].

Now we need to simplify this. So multiply and divide by conjugate of denominator.

[tex]\frac{2\sqrt{2}}{\sqrt{3}-\sqrt{2}}[/tex]

[tex]=\frac{2\sqrt{2}}{\left(\sqrt{3}-\sqrt{2}\right)}[/tex]

[tex]=\frac{2\sqrt{2}}{\left(\sqrt{3}-\sqrt{2}\right)}\cdot\frac{\left(\sqrt{3}+\sqrt{2}\right)}{\left(\sqrt{3}+\sqrt{2}\right)}[/tex]

[tex]=\frac{2\sqrt{6}+2\sqrt{4}}{\left(\sqrt{3}\right)^2-\left(\sqrt{2}\right)^2}[/tex]

[tex]=\frac{2\sqrt{6}+2\cdot2}{3-2}[/tex]

[tex]=\frac{2\sqrt{6}+4}{1}[/tex]

[tex]=2\sqrt{6}+4[/tex]

[tex]=4+2\sqrt{6}[/tex]

Step-by-step explanation:

The mid segment unites the middle of two sides of a triangle.  In this case, the question wants us to have it parallel to BC, so it has to unite the middle of AB to the middle of AC.

The use of the clear grid in this case makes that we don't have to use any angle calculation.

If you start from point B, you'll need to go 6 units to the right and 8 units up to meet with A. That means the center point is located 3 units right and 4 units high from point B... so, we have point (4,2).

Starting from C, we do a similar calculation.  you need to go 2 units to the left and 8 units up... so the mid-point is 1 unit to the left and 4 units up... so (8,2).
