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

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:

x+2 is answer by division

Answer:

b = 5 / 9

Step-by-step explanation:

8/9x + b = 1/9(8x + 5)

Make b the subject of formula.

b = 1/9 (8x + 5) - 8/9x

Multiply through by 9

9b = 9 * 1/9 ( 8x + 5) - 9 * 8/9x

9b = 8x + 5 - 8x

9b = 5

b = 5 / 9

The value of b = 5 / 9

Answer:

247.5

Step-by-step explanation:

220 + (12.5% × 220)

220 + 12.5% × 220

(1 + 12.5%) × 220

(100% + 12.5%) × 220

112.5% × 220

112.5 ÷ 100 × 220

112.5 × 220 ÷ 100

24,750 ÷ 100 = 247.5

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:

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

Answer: m/3 cents

Step-by-step explanation:

Hi, to answer this question we have to divide the total cost of the chips (m) by the number of bags of chips (3).

Mathematically speaking:

Cost of one bag chip: m/3 cents

Since the total cost is represented by a variable, the individual cost is an expression.

If we replace the value of m by a number we will obtain the result as a number.

x = 4 - 2y.......... equation 1

-4x -7y = - 9.......equation 2

Putting equation 1 in equation 2

- 4 ( 4 - 2y) - 7y = - 9

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.

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:

Step-by-step explanation:

I'm assuming you want to do the following synthetic division:

1 /       1        2        -3        3

                   1          3        0

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

          1        3         0         3            The remainder is 3.

The remainder is -2

The remainder in synthetic division is the constant term of the quotient. To find the remainder of the synthetic division problem above, we can use the following steps:

Arrange the coefficients of the dividend and divisor in descending order of degree.

Set up the synthetic division table as follows:

     2 -3 3 |1

   ---------------

   1

Bring down the first coefficient of the dividend.

Multiply the coefficient we just brought down by the divisor and place the product in the next column.

Subtract the product from the corresponding coefficient of the dividend and place the difference in the next column.

Repeat steps 4 and 5 until we reach the last column.

The remainder is the last number in the bottom row of the synthetic division table.

Following these steps, we get the following synthetic division table:

     2 -3 3 |1

   ---------------

   1  2 -1

   -2 -4 2

   --------

   -2

Therefore, the remainder is -2
