Answer:

Step-by-step explanation: the degree is 0

Final answer:

The degree of the monomial -4/9 is 0 since it contains no variables and can be considered to have variables with an exponent of 0.

Explanation:

The degree of a monomial is the sum of the exponents of all its variables. In the case of the monomial -4/9, there are no variables present, which means that the degree is 0. This is because the monomial can be considered to have variables raised to the power of 0, and any number (except zero) raised to the power of 0 is 1, which does not affect the value of the coefficient (-4/9).

Answer:

4 3/8

Step-by-step explanation:

8 × 1 + 7 = 15/8

3 × 2 + 1 = 7/3

Now, we'll multiply both numerator and denominators.

(numerators) 15 × 7 = 105

(denominators) 8 × 3 = 24

= 105/24

Now, we'll find the simplest form of 105/24

= 4 3/8

The measure of the complimentary angle is 60 degrees.

The complimentary angle is the angle where the sum of angles should be 90 degrees

Since An angle measures 30 degrees.

So, the measure of an angle should be

= Sum of angles - one measurement of angle

= 90 - 30

= 60 degrees

Therefore we can conclude that The measure of the complimentary angle is 60 degrees.

Answer:

a. = 111 inches squared b.= 506 inches squared c.=143 inches squared

Step-by-step explanation:

a.

To find the area I broke the shape into two parts one where you multiply 7 and 9 to get the area and one where you multiply 12 and 4 to get the area. The first area is 63 and the second is 48 and together the entire area is 111 inches squared    

b.

To find the area here you do the same thing as a. you break the shape into two parts a part where you multiply 29 and 14 and a part where you multiply 20 and 5. In all you get 506 inches squared.

c.

A model's scale ratio is the proportionate ratio of dimensions. The actual motorcycle stands at a height of 48 inches.

A model's scale ratio is the proportionate ratio of a linear dimension of the model to the equivalent characteristic of the original.

The length of the motorcycle is 96 inches, while the length of the scale model of the motorcycle is 6 inches. Therefore, the scale ratio can be written as,

[tex]\rm Scale\ Ratio = \dfrac{\text{The actual length of the motorcycle}}{\text{The model length of the motorcycle}}\\\\Scale\ Ratio = \dfrac{96}{6} = 16[/tex]

Using the same ratio the height of the motorcycle can be written as,

[tex]\rm Scale\ Ratio = \dfrac{\text{Actual height of the motorcycle}}{\text{Model height of the motorcycle}}\\\\\\16=\dfrac{\text{Actual height of the motorcycle}}{3}\\\\\\{\text{Actual height of the motorcycle}} = 16 \times 3 = 48\ inches[/tex]

Hence, the actual motorcycle stands at a height of 48 inches.

Answer:

option A

Step-by-step explanation:

log_2(100)

we can simplify it

we can use base change formula

log_2 (100)=\frac{ln\left(100\right)}{ln\left(2\right)}

log_2 (100)=6.643856

Second value is :

log_6(20)

we can simplify it

we can use base change formula

log_6(20)=\frac{ln\left(20\right)}{ln\left(6\right)}

log_6(20)=1.67195

so, we know that

6.6438 is almost 4 times of 1.67195

The value of log₂ (100) is about 4 times the value of log₆(20). The correct answer would be an option (A).

There are four basic properties of logarithms:

logₐ(xy) = logₐx + logₐy.

logₐ(x/y) = logₐx - logₐy.

logₐ(xⁿ) = n logₐx.

logₐx = logₓa / logₓb.

According to the problem, we will use some of the basic logarithmic properties,

The logarithms expression is given, as follows:

log₂(100)

It can use the base change formula,

log₂ (100) = ln (100) / ln (2)

log₂ (100) = 6.643856

The second value is :

log₆(20)

It can use the base change formula

log₆(20) = ln (20) / ln (6)

log₆(20) = 1.67195

Since 6.6438 is almost 4 times 1.67195

Hence, the correct answer would be option (A).

The coordinate of the point is (-1,-1).

The answer is option B) (-1, -1).

To identify the x-coordinate of a point on a graph, read the number on the x-axis directly above or below the point. To identify the y-coordinate of a point, read the number on the y-axis directly to the left or right of the point. Remember, to write the ordered pair using the correct order (x,y).

An ordered pair (x, y) represents a position of a point on a coordinate graph, where x is the number on the x-axis that the point lines up with and y is the number on the y-axis that the point lines up with. The numbers x and y in the ordered pair (x, y) are called coordinates.

Answer:

8.5pi

Step-by-step explanation:

We can solve this problem with a rule of three.

The area of the whole circle is represented by a sector with central angle of 2*pi. So, if we want to find the area of a sector that has a central angle of 17pi/9, we can use the following logic:

sector of 2pi -> area equal to 9pi

sector of 17pi/9 -> area equal to X

2pi / (17pi/9) = 9pi / X

18 / 17 = 9pi / X

X = 17 * 9pi / 18 = 17pi / 2 = 8.5pi

Step-by-step explanation:

I just did it and got it right

The slant-height of the pyramid having perpendicular height as 3 units, base as 1 unit is : (b) √10.

A Pyramid is a three-dimensional geometric shape with a polygonal base and triangular faces that meet at a single point called the apex. The base can be any polygon, and the number of sides of the base determines the type of pyramid (e.g., a square base yields a square pyramid)

The "Slant-Height" of the given pyramid can be calculated by using Pythagoras-Theorem, which states that; (slant-height)² = (perpendicular)² + (base)²;

Substituting Perpendicular height as 3 units, base as 1 unit, and slant-height as "x";

We get,

⇒ 3² + 1² = x²,

⇒ x² = 9 + 1,

⇒ x² = 10,

⇒ x = √10,

Therefore, the slant-height is √10, option (b) is correct.

Side length = 7 inches

This number is a rational number, because it is a whole number and it can be represented as a fraction (7 = 14/2 for example)

Step-by-step explanation:

The volume of the pyramid can be calculated as:

V = (1/3)*A*h

Where V is the volume, A is the area of the base and h is the height.

If the volume is 73.5 in3 and the height is 4.5 in, we can find the area of the base:

73.5 = (1/3)*A*4.5

A = 73.5*3/4.5 = 49 in2

As the pyramid have a square base, we can calculate the side length of the base:

A = L*L (L = length)

49 = L^2

L = 7 inches

This number is a rational number, because it is a whole number and it can be represented as a fraction (7 = 14/2 for example)
