$28.62

Step-by-step explanation:

$36.00/4=$9.00*1.06=$28.62

Answer:

1. 35 km

2. 1 cm to 5m

3. 6 cm

4. [tex]42^\circ[/tex]

5. 16.73 m

Step-by-step explanation:

Solution 1.

Reading of map scale = 1cm:5km

i.e. 1 cm is equivalent to 5 km

Measurement of map  = 7 cm

Actual distance = Measurement of map [tex]\times 5[/tex]

Actual distance = 7 [tex]\times 5[/tex] = 35 km

-------------------

Solution 2.

Length of dining hall = 35 m

Measurement of map = 7 cm

Scale = Measurement of map : Length of dining hall (i.e. ratio)

Scale = 7 cm :35 m = 1 cm : 5 m

-------------------

Solution 3.

Length of building = 30 m

Scale = 1 cm to 5m

5 m is equivalent to 1 cm on scale

1 m is equivalent to [tex]\frac{1}{5}[/tex] cm on scale

30m is equivalent to [tex]\frac{1}{5} \times 30[/tex] = 6 cm on scale

-------------------

Solution 4.

Angle of elevation of A from B = [tex]42^\circ[/tex]

Angle of depression of B from A = ?

Please refer to the image attached, we can clearly observe that both the angles (i.e. angle of elevation from A to B and angle of depression from B to A )will be equal.

Angle of depression of B from A = [tex]42^\circ[/tex]

-------------------

Solution 5.

Given that:

String length, or hypotenuse of triangle BC= 25 m

Angle of string with horizontal, [tex]\angle B = 42^\circ[/tex]

Please refer to the attached image for the clear understanding of the situation.

To find:

Height, AC = ?

We can use trigonometric identity:

[tex]sin\theta = \dfrac{Perpendicular}{Hypotenuse}[/tex]

OR

[tex]sinB = \dfrac{AC}{BC}\\\Rightarrow sin42^\circ = \dfrac{AC}{25}\\\Rightarrow AC = 25 \times 0.67\\\Rightarrow AC = 16.73 m[/tex]

============

So, the answers are:

1. 35 km

2. 1 cm to 5m

3. 6 cm

4. [tex]42^\circ[/tex]

5. 16.73 m

Answer:

1). a = 9.42 m

2). b = 6.37 m

3). c = 4.48 m

Step-by-step explanation:

In the figure attached,

By applying tangent rule in triangle ADE,

tan47 = [tex]\frac{h}{c}[/tex]

c = [tex]\frac{h}{\text{tan}47}[/tex]

c = [tex]\frac{4.8}{\text{tan}47}[/tex]

c = 4.476

c ≈ 4.48 m

Now we apply the same rule in triangle ACE,

tan37° = [tex]\frac{h}{b}[/tex]

b = [tex]\frac{h}{\text{tan}37}[/tex]

b = [tex]\frac{4.8}{1.0724}[/tex]

b = 6.37 m

Now apply the tangent in triangle ABE,

tan27° = [tex]\frac{h}{a}[/tex]

a = [tex]\frac{h}{\text{tan}27}[/tex]

a = [tex]\frac{4.8}{0.5095}[/tex]

a = 9.42 m

Answer:

x= -3,      x = 1

Step-by-step explanation:

Zeros are values of x, when f(x) = 0.

0=(x+3)(x-1)

x+3 = 0,  x - 1=0

x= -3,      x = 1

Answer:

x = -3, x = 1

Step-by-step explanation:

To determine the zeroes of the factored quadratic equation, we need to look back at its definition. The zeroes are a function are specific x-values that result in a y-value of 0.

In this case, we want the numbers inside of the parantheses to equal 0. If we substitute in x = -3, we get (0)(x - 1), and we know that is just 0. Similarly, if we substitute in x = 1, we get (x + 3)(0), and we know that is just 0.

As such, these are your solutions.

Answer

Go 6 across to the right and 8 up from there

Step-by-step explanation:

Answer:

This is a coordinate, and it tells you where to plot a point on a set of axis. The first number in the coordinate tells you the x-value and the second one tells you the y-value. X-values go across the horizontal axis, known as the x-axis. Y-values go up and down the vertical axis, known as the y-axis.

In this case, to plot the point, you would start at the very center of the axis, where y and x both equal 0. You'd go 6 to the right, because they gave you a positive x-value. The you'd go up 8, because they gave you a positive y-value.

If they give you a negative x-value, you'd go to the left, and if they give you a negative y-value, you'd go down.

Answer:

the answer is C

Step-by-step explanation:

Rotate 90 degrees counterclockwise , the translate three units to the left

Option C is the correct transformation to transform ABCD to A'B'C'D'.

Rotation

Rotate the square ABCD counterclockwise about the origin. Sides AD and BC of square ABCD will become parallel to the sides A'D' and B'C' respectively of the square A'B'C'D'. The square ABCD is, thus, oriented the same way as the square A'B'C'D'.

Vertical Translation

After the rotation, the side AB is 1 unit above the y-axis, which is the same as that of the square A'B'C'D'. So, the vertical position of the square ABCD is the same as that of the square A'B'C'D'.

Horizontal Translation

The side AD of the square ABCD is 5 units to the left of the x-axis. The side A'D' of the square A'B'C'D' is 8 units to the left of the x-axis. So, translate the square ABCD to the left by 3 units to coincide with the position of A'B'C'D'.

Thus, to obtain A'B'C'D' from ABCD first rotate it by 90° counterclockwise then, translate it to the left by 3 units.

Answer:

dimensions are 2.19 inches by 9.14 inches

Step-by-step explanation:

Here, we are interested in knowing the dimensions of the rectangle

Now, let the width of the rectangle be x, from the question, we can write;

6x-4 as the length

Area of rectangle = l * b

x(6x-4) = 20

6x^2 - 4x = 20

divide through by 2

3x^2-2x = 10

3x^2 -2x -10 = 0

using quadratic formula;

x = -b ± √(b^2 - 4ac)/2a

From the quadratic equation, a = 3, b = -2 and c = -10

substituting these values, we have

x = 2 ± √(-2)^2 -4(3)(-10))/6

x = 2 ± √(124)/6

x = 2 + √(124)/6 or 2 - √(124)/6

x = (2+11.14)/6 or (2-11.14)/6

x = 2.19 or -1.52

Since width cannot be negative, we choose 2.19 alone

So the length is 6(2.19) -4 = 9.14

Answer:

(2, 4)

x = 2

y = 4.

Step-by-step explanation:

To find the solution to the system of equations, we can simply set the two equations equal to each other as shown:

x + 2 = 3x - 2

Subtract 'x' from both sides:

2 = 2x - 2

Add '2' to both sides:

4 = 2x

x = 2.

Plug this value for 'x' into an equation to solve for 'y':

y = (2) + 2

y = 4.

Therefore, the solution to the system is (2, 4).

Answer:

Y=4

Step-by-step explanation:

How I did this.

y=x+2 y=3x-2

Moved around (you can do this)

y=2+2 y= 3x-x

y=4.

Step-by-step explanation:

Since, the triangle PQR is rotated 360° around the origin so, Q' will coincide with Q, and in this way their coordinates would be same.

Therefore, Q' (6, 3)

The correct answer is (6,3)

Because if you rotate any coordinate points 360 degrees around the origin, it will always remain the same.

Answer:

60

Step-by-step explanation:

All angles = 180

All sides are equal

Therefore, 180/3 = angle degrees = 60

x is an opposite angle of bottom right angle therfore x = 60

Answer:

(a) x = 60°

(b) Angle x is alternate to the right base angle of the equilateral triangle.

Step-by-step explanation:

(a) The triangle in the figure above is an equilateral triangle in which all sides and angles are equal. The sum of angles in a triangle is 180°. Each angle in the equilateral triangle is 60° (180°/3 = 60°)

Therefore, angle x is 60°.

(b) Alternate angles are equal. Angle x and the right base angle of the equilateral triangle are alternate angles. Therefore, angle x is 60°.

Answer:

A) inside the circle

Step-by-step explanation:

equation of the circle is:

[tex](x-a)^{2} + (y-b)^{2} = r^{2}[/tex]

where (a,b) is center of the circle and r is radius so

[tex]x^{2} + y^{2} = r^{2}[/tex] now plug in given point to find the radius

[tex](6)^{2} + (-4)^{2} = r^{2}[/tex]

36 +16 = 52 so

r = [tex]\sqrt{52}[/tex]  ≈ 7.2 or  [tex]r^{2} =52[/tex]

when you plug point (√2 , -7) into equation of the circle

(√2)^2 + (-7)^2 = 2 +49 =51

51 is less than 52 so this is inside of the circle
