Solve the inequality. g – 6 > –1

Answer:405

Step-by-step explanation:

The probability of drawing a red marble first and a green marble second (without replacement) from a box containing 5 red, 8 green, 4 blue, and 3 yellow marbles is 2/19.

In the scenario you've described, you would first calculate the probability of selecting a red marble from the box. You have 5 red marbles and a total of 20 marbles (5+8+4+3), so the probability of drawing a red marble first is 5 out of 20, or 1/4.

When you draw a second marble without replacing the first, you have a slightly altered situation - the total number of marbles in the box now comes down to 19. We are interested in the probability of drawing a green marble now. As there are 8 green marbles, probability of drawing a green marble is 8 out of 19, or 8/19.

Probability of a red marble being picked first and then a green marble without replacement is calculated as: P(Red and then Green) = P(Red) * P(Green | Red is already picked). This equals 1/4 * 8/19 = 8/76 = 2/19.

The total amount repaid by Melvin for the specified case is given by: Option C. $1,440

For finding the total amount repaid, we need to find how repeated addition can be evaluated using multiplication.

Suppose that there are two positive integer numbers( numbers like 1,2,3,.. ) as a and b

Then, their multiplication can be interpreted as:

[tex]a \times b = a + a + ... + a \: \text{(b times)}\\\\a \times b = b + b +... + b \: \text{(a times)}[/tex]

For example,

[tex]5 \times 2 = 10 = 2 + 2 + 2 + 2 + 2 \: \text{(Added 2 five times)}\\or\\5 \times 2 = 10 = 5 + 5 \: \text{(Added 5 two times)}[/tex]

Since Melvin paid $60 for 24 months, so the amount he paid is $60 added 24 times, or:

Total amount paid by Melvin for furniture buying = 60  + 60 + ... + 60 (24 times) = [tex]24 \times 60 = 1440 \text{\: (in dollars)}[/tex]

Thus, the total amount repaid by Melvin for the specified case is given by: Option C. $1,440

Answer:

2.23 3.426 4.32321... are repeating and 1.01011 is not repeating

The decimal 1.01011 is a non-repeating decimal. For the others, 2.23, 3.426, and 4.321321... are all repeating decimals because they have digits or group of digits that repeat indefinitely.

In mathematics, decimals are either repeating or nonrepeating. A repeating decimal is a decimal that has a digit or group of digits that repeats infinitely. A non-repeating decimal doesn't have a pattern of digits that repeats infinitely.

Answer:

Option D is correct.

Explanation:

From the given figure,

Labelled the black triangle as A, B and C

The coordinates of  triangle ABC are;

A= (2,8) , B= (2,5) and C=(6,5)

To find the glide reflection image of the triangle ABC.

Glide Reflection: It is a composition of transformations.

In glide reflection, a translation is first performed on the figure then it is reflected over a line.

Given: The rule of translation is: [tex](x,y) \rightarrow (x, y-7)[/tex] and line of reflection is x= 1.

Now, apply the rule of translation on black triangle, we get;

[tex]A (2,8) \rightarrow (2, 8-7)[/tex] = A' (2,1)

[tex]B (2,5) \rightarrow (2, 5-7)[/tex] =B' (2,-2)

[tex]C (6,5) \rightarrow (6, 5-7)[/tex] = C' (6,-2)  

Next,

Apply the rule of reflection over the line x =1,

i.e, [tex](x,y) \rightarrow (-x+2, y)[/tex]

[tex]A' (2,1) \rightarrow (-2+2, 1)[/tex] =A" (0,1)

[tex]B' (2,-2) \rightarrow (-2+2, -2)[/tex] =B" (0,-2) and

[tex]C' (6,-2) \rightarrow (-6+2, -2)[/tex] =C" (-4,-2)

You can see the graph of Glide reflection as shown below in the attachment.

Answer: The factorized form of [tex]n^2-25[/tex] will be

[tex](n-5)(n+5)[/tex]

Explanation:

Since we have given that

[tex]n^2-25[/tex]

Now, we need to factorize the expression,

We know the formula for "difference of squares" which is given by

[tex]a^2-b^2=(a+b)(a-b)[/tex]

Using the formula, we get

[tex]n^2-25=n^2-5^2=(n-5)(n+5)[/tex]

Hence, the factorized form of [tex]n^2-25[/tex] will be

[tex](n-5)(n+5)[/tex]

Answer:

271.3 mm^3

Step-by-step explanation:

Volume of a cylinder = πr^2h

To find the answer, we need to find the difference between the large cylindrical and small cylindrical  pipes.

V = π h (R^2 – r^2)

Given: h= 10, R is outer radius = 8.4/2 = 4.2, r is inner radius = 6/2 = 3

V = π (10) (4.2^2 – 3^2)

V= 3.14*10(17.64 - 9)

V = 31.4(8.64)

V = 271.3 mm^3

The volume of metal in the pipe 271.3 mm^3

Hope this will helpful.

Thank you.

The volume of the metal in the pipe is 271.3 mm³.

A cylinder is a three-dimensional shape. It is a prism with a circular base.

Volume of a cylinder = πr²h

Where:

π = 3.14 = PI

r = radius = diameter / 2

The volume of the metal in the pipe = volume of the metal pipe - volume of the hole

3.14 x 10 x [(8.4/2)² - (6/2)²]

3.14 x 10 x [17.64 - 9}

3.14 x 10 x 8.64

= 271.3 mm³

Inequalities describe a range of possible values and are useful in fields like business, economics, and physical sciences. They allow for decisions based on a range of results, like determining minimum product sales for profit. However, they don't provide specific values, which is a limitation in some contexts.

Many people would be interested in using inequalities in a range of fields, including business, engineering, economics, physical sciences, and mathematics. The use of inequalities provides benefits when you need to understand a range of possible values rather than a specific number. This allows decisions to be made based on a range of acceptable outcomes.

For example, in a business setting, inequalities can be used to determine the minimum number of products that need to be sold to achieve a certain profit. If the goal is to earn at least $500, the inequality would be nx > 500, where n is the price per unit and x is the number of units sold.

However, inequalities have their limitations. They provide a range of answers, not specific solutions. Thus, they may not be suitable in situations where precise values are needed. They also imply that all values within the range are equally acceptable, which might not always be the case.

To multiply 1.3 x 10^-2 and 0.05 in scientific notation, convert 0.05 to 5 x 10^-2. Multiply 1.3 by 5 to get 6.5, then add the exponents to get 6.5 x 10^-4, which is the final answer in scientific notation.

The question asks to calculate the multiplication of 1.3 x 10^-2 and 0.05 and express the result in scientific notation. To solve this arithmetic with numbers in scientific notation, you should multiply the decimal numbers and add the exponents of the ten's powers. The decimal multiplication is 1.3 multiplied by 0.05, which equals 0.065. Since 0.05 is not in scientific notation, it can be written as 5 x 10^-2 to simplify the calculation. Thus, the multiplication becomes (1.3 x 10^-2) x (5 x 10^-2). The next step is to multiply the decimal parts, 1.3 and 5, getting 6.5. The exponents of ten are then added together: -2 + (-2) = -4. The final multiplication gives us 6.5 x 10^-4. However, for true scientific notation, the leading number must be between 1 and 10, so we rewrite 6.5 as 6.5 x 10^0. The final scientific notation is therefore 6.5 x 10^-4.
