With the concepts of ratio, Siu's height is 121 cm tall.

We can determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio. Ratios can be divided into two groups. One is the part-to-whole ratio, and the other is the part to part ratio. The link between two distinct entities or groupings is depicted by the part-to-part ratio.

A ratio is a comparison between two amounts that often uses a fraction.

Considering that the fraction has been simplified,

Given that Siu's height is 5x

Tai's height is 6x.

Now, 6x= 145

Thus, x= 145/6

Now, Siu's height is 5x

Then, its height is (145 ×5)/6= 120.8 cm

Siu's height is 121 cm because it must be rounded to the closest centimeter.

Answer:

10.5

Step-by-step explanation:

The 5 chicken wings will cost $10.5 to Enola.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Price of 14 chicken wings bought by Enola = $29.40.

To find the price of 5 wings,

Use ratio property,

Price of 14 chicken wings = $29.40

Price of 1 chicken wing = 29.40 / 14

                                       = 2.1

Price of 5 chicken wings = 2.1 x 5 = 10.5

The price of the 5 chicken wings is $10.5.

C = (15 x 3) + 35 = 80

The third option is the correct method that solves for the variable r in the equation

Given the equation: 3/8r+ 2 = 14

Subtract 2 from both sides:

3/8r = 12

Multiply both sides by 8:

3r = 12 x 8

3r = 96

Divide both sides by 3:

r = 96/3 = 32

The equivalent expression of the perimeter in two terms is 44 + 4x

From the question, the area of the garden is given as

A = 15(2x + 7)

The area of a rectangle is calculated using

A = LW

Where

Length = L

Width = W

This means that

L = 15

W = 2x + 7

The perimeter of the rectangular garden is then calculated as

P = 2 * (L + W)

So, we have

P = 2 * (15 + 2x + 7)

Evaluate

P = 2 * (22 + 2x)

This gives

P = 44 + 4x

Line 2 has a positive slope with respect to the angle made with the x-axis.

Slope refers to the tan of the angle with the x-axis. For example. if the line makes an angle β with the x-axis, then the slope is the tan β.

Now taking line 1,

The line is parallel to the x-axis, therefore the line makes 0 angles with the axis which gives slope 0.

Now taking line 2,

The line passes to the origin and has the equation x=y, thus the slope is 1

Now taking line 3,

The line is parallel to the y-axis, therefore the line makes 90°, thus the slope is 1/0 which gives infinity.

Now taking line 4,

The line is making an angle of 60°, therefore the line is having a slope:       - [tex]\sqrt{3}[/tex]

The coordinates of the vertices after the reflection over the x-axis are A' (2, -3) B' (4, 5) and C' (-1, -2)

Given,

A triangle ABC with vertices A(2,3) , B(4,-5), and C(-1,2)

To find the coordinates of the vertices of each figure after a reflection over the given axis.

Now, According to the question:

We should know that:

You should know that you can predict changes in coordinates after translations without a graph or anything like that.

(x, y) reflected over the x axis = (x, -y)

(x, y) reflected over the y axis = (-x, y)

(x, y) rotated 90 degrees around the origin = (y, -x)

(x, y) rotated 180 degrees around the origin = (-x, -y)

(x, y) rotated 270 degrees around the origin = (-x, y)

So here's our set of points.

A(2,3) , B(4,-5), and C(-1,2)

Here's those points reflected over the x axis.

A' (2, -3) B' (4, 5) and C' (-1, -2)

The measure of the lableled angles are x = 202 and  (x - 44) = 158

Before we can solve this question, we need to understand the geometry of the shape.

The shape we have here is a pentagon. The sum of angles in a pentagon is 540.  The angle with a red square is a right angle and the value is 90.

Therefore:

x + 90 + 90 + (x - 44) = 540

x + 180 + x - 44 = 540

2x + 136 = 540

2x = 540 - 136

2x = 404

x = 404/2

x = 202

Also:

(x - 44) = 202 - 44 = 158

Using trigonometry, it is found that:

1. Graph 2 shows an angle in which cos(θ) = -8/17 and sin (θ) is negative.

2. The angles are θ = 157.38º and θ = 202.62º, as shown in Graph 1.

3. Graph 3 shows an angle of θ = 315º.

In item 1, it asks for an angle in which both the sine and the cosine of the angle are negative. This happens in the third quadrant, hence Graph 2 shows an angle in which cos(θ) = -8/17 and sin (θ) is negative.

The secant of an angle is given by one divided by the cosine of the angle, that is:

sec(θ) = 1/cos(θ)

Considering the numeric value of the secant in this problem, we have that:

-13/12 = 1/cos(θ)

-13cos(θ) = 12

cos(θ) = -12/13

The cosine is negative in the second and the third quadrant, hence graph 1 shows these equivalent angles.

Applying the inverse cosine, the angles are given as follows:

θ = arccos(-12/13)

θ = 157.38º and θ = 202.62º. (two equivalent angles).

An angle of 315º is on the fourth quadrant of the unit circle, hence Graph 3 shows this angle.

The correct equations which can be used to represent when she will be able to purchase the bicycle she wants are:

Given, Eva wants to buy a bicycle.

The cost of bicycle is = $250

Saving's of Eva = $125

Eva plans on washing cars for $25 per car.

Eva wash 'c' cars to have enough to purchase the bicycle.

cost of bicycle = saving's of Eva + Eva washing 'c' cars for $25 per car.

⇒ 250 = 125 + 25c

arrange the like terms on one side.

⇒ 250 - 125 = 25c

⇒ 125  = 25c

⇒ 25c = 125

⇒ c = 125/25

⇒ c = 5

hence Eva washes 5 cars to earn $125 which gets added to the savings and becomes the cost of the bicycle she wants to purchase.

⇒ cost of bicycle = 125+25(5)

⇒ cost of bicycle = 125+125

The rate of pounds per hour of the machine is 1.5 pounds per hour

From the question, we have the following parameters:

Pounds of nails = 2 1/4 pounds of nail

Number of hours = 1 1/2 hour

From the above parameters, the rate of pounds per hour can be calculated using the following formula of constant of proportionality

The constant of proportionality is calculated as

Constant of proportionality = Pounds of nails/Number of hours

In this case, we have

Rate of pounds per hour = Pounds of nails/Number of hours

Substitute the known values in the above equation

Rate of pounds per hour = (2 1/4)/(1 1/2)

So, we have

Rate of pounds per hour = 1.5

Given the graph of f(x), we are required to determine whether the degree of the function is ODD or EVEN, and also to determine whether the function itself is ODD.

An odd function is defined as a function that has f(–x) = –f(x) for any value of x. The opposite input gives the opposite output.

From the given graph of f(x), the function f(x) is ODD.

The degree of the function f(x) is odd since the f(x) itself is odd.
