Answer 1

9514 1404 393

Answer:

x = 1

Step-by-step explanation:

The diagram is intended to show you that the whole is the sum of the part:

11 = (10x -1) +(2x)

11 = 12x -1 . . . . . . . collect terms

12 = 12x . . . . . . . . add 1 to both sides

1 = x . . . . . . . . . . . divide both sides by 12

The value of x is 1. The lengths of the segments are 9 and 2.

What is the value of the expression?

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The expression is given below.

⇒ {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7)

Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction are all part of the PEMDAS formula. To answer the problem properly and accurately, this rule must be followed.

⇒ {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7)

⇒ {[(−30) ÷ (−30)]² − 15} ÷ (−7)

⇒ {[1]² − 15} ÷ (−7)

⇒ {1 − 15} ÷ (−7)

⇒ (−14) ÷ (−7)

⇒ 2

The value of the numerical expression {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7) will be 2.

1. A rectangular canvas picture measures 12 inches by 28 inches. The canvas is mounted inside a frame of uniform width, increasing the total area covered by both canvas and frame to 612 square inches. Find the uniform width of the frame.

Answers

The uniform width of the frame is 16.61 inches.

Since a rectangular canvas picture measures 12 inches by 28 inches, and the canvas is mounted inside a frame of uniform width, increasing the total area covered by both canvas and frame to 612 square inches, to find the uniform width of the frame you must perform the following calculation:

√ (612 - (28 x 12)) = X √ (612 - 336) = X √276 = X 16.61 = X

Therefore, the uniform width of the frame is 16.61 inches.

what is the geometric sequence and the 8th term and the 10th term

Answers

Answer:

The geometric sequence is decreasing by 0.5 * each term

common ratio = 0.5

an equation for this exact sequence would be

50(0.5)^x-1

Step-by-step explanation:

To find the common ratio for a geometric sequence we can divide the previous term value by the next term value

so 50 / 25 = 0.5

and to check we can divide

25 / 12.5 = 0.5

So our common ratio is 0.5

Step-by-step explanation:

Given sequence:

50, 25, 12.5, ...

The first term is 50 and the common ratio is:

r = 12.5/25 = 25/50 = 1/2

The equation:

tₙ = t₁rⁿ⁻¹tₙ = 50(1/2)ⁿ⁻¹

Find the 8th and 10th terms:

t₈ = 50(1/2)⁷ = 0.390625t₁₀ = 50(1/2)⁹ = 0.09765625

Answers

Step-by-step explanation:

I'm not sure but i believe is that one

The best definition of the term "reciprocal" is: A fraction that is the multiplicative inverse of the given fraction. The correct option is option B

What is fraction reciprocal?

The reciprocal of a fraction is obtained by swapping the numerator and the denominator of the fraction. It is a number that, when multiplied by another number, results in a product of 1. For example, the multiplicative inverse of 2 is 1/2, because 2 × 1/2 = 1. In general, if a number "a" has a multiplicative inverse "b," then a × b = 1. However, not all numbers have multiplicative inverses.

Reciprocals are also knowns as multiplicative inverse. Multiplicative inverses are essential in various mathematical operations and concepts, including fractions and solving equations involving division.

Answer:

|3x +5| = 3x +1|3x +5| = x -1

Step-by-step explanation:

The left-side expression will not intersect the right side expression if the slopes are the same and the y-intercepts are chosen appropriately. An example is ...

|3x +5| = 3x +1

The right-side line stays below the left-side V, so doesn't intersect.

You can choose the slopes to be different, also, if you make the intercepts such that the right-side line does not intersect the left-side V. An example of that is ...

|3x +5| = x -1

Answer:

a. y = -2x-5

Step-by-step explanation:

*Don't get confused the y-axis scale is 2

I guess you would kind of have to guess by looking at the graph for this one, the y-intercept is 5.

The graph is negative because it is pointing the opposite way

The slope is 2 because the y-axis has a scale of 2

With these facts you can formulate that the equation would be y = -2x-5
