Let's calculate the value of c using Pythagoras theorem ~

[tex]\qquad \sf  \dashrightarrow \: c {}^{2} = a {}^{2} + {b}^{2} [/tex]

[tex]\qquad \sf  \dashrightarrow \: 40 {}^{2} = {24}^{2} + {b}^{2} [/tex]

[tex]\qquad \sf  \dashrightarrow \: b² = \sqrt{40² - 24²} [/tex]

[tex]\qquad \sf  \dashrightarrow \: b= \sqrt{1600-576} [/tex]

[tex] {\qquad \sf  \dashrightarrow \: b= \sqrt{1024}} [/tex]

[tex]\qquad \sf  \dashrightarrow \: b = 32 \: units[/tex]

The length of "b"

[tex] {c}^{2} = {a}^{2} - {b}^{2} [/tex]

[tex] {b}^{2} = {40}^{2} - {24}^{2} [/tex]

[tex]b = 1024[/tex]

[tex]b = \sqrt{1024} [/tex]

[tex]b = 32[/tex]

Hence, the length of "b" is 32.

Answer:

424

Step-by-step explanation:

SF: 2{(8 x 4) + (4 x 15) + (8 x 15)}

therefore: 2 [32 + 60 + 120]

therefore: 64 + 120 + 240

therefore: 360 + 64

therefore: 424

Answer:

424

Step-by-step explanation:

To find the surface area, you need to find the area of all the faces of the shape. Because this is a rectangle, you only need to find the 3 different faces and then multiply them by 2. For the largest face, the dimensions are 8*15, which is 120. Multiply that by 2 and you get 240. For the long, slim face, the dimensions are 4*15, which is 60. Multiply that by 2 and you get 120. Finally, the smallest face's dimensions is 8*4, which is 32. Double that and you get 64. Now all you need to do is add all the products up. 240+120+64 is 424, which is your answer.

Answer:

$208.30

Step-by-step explanation:

Let the original price be $ x

Discount % = 12%

Discount = $ 25

 12% of x = 25

  [tex]\sf \dfrac{12}{100}*x = 25[/tex]

           [tex]\sf x = 25 * \dfrac{100}{12}=\dfrac{25*25}{3}\\[/tex]

It is the reverse of differentiation.

Then the general indefinite integral will be

[tex]\rm \rightarrow \int (4+ x^5) dx \\\\\rightarrow 4x + \dfrac{x^6}{6} + c[/tex]

Where c is the constant of integration.

The profit that Jim got in percentage will be 46.67%.

A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.

The profit is given as,

Profit = Selling price - Cost price

Jim buys a wardrobe for £30. He sells it for £44. The profit is calculated as,

Profit = £44 - £30

Profit = £14

The profit in percentage is calculated as,

P = (£14 / £30) x 100

P = 0.4667 x 100

P = 46.67%

Answer:

well you might not have to do summer school but you might have to take a course during summer for that class you failed or you may have to redo that class in order to get the points needed to pass but also it depends because even though you might  not pass that one class you can still pass the grade but you will be in the same class or a lower standard for that subject now i am not sure it honestly all depends on your teacher and school if they want you to go the next grade but they can also talk to teachers in the next grade to help you so that you can still pass but you have to do lower standard work  for the class in that next grade

In systematic sampling, individuals are selected at regular intervals from the sampling frame.

Stratified sampling- In this method, the population is first divided into subgroups (or strata) who all share a similar characteristic

Clustered sampling.- a clustered sample, subgroups of the population are used as the sampling unit, rather than individuals. The population is divided into subgroups, known as clusters, which are randomly selected to be included in the study

Simple random sampling. -In this case each individual is chosen entirely by chance and each member of the population has an equal chance, or probability, of being selected.

Quota sampling--This method of sampling is often used by market researchers. Interviewers are given a quota of subjects of a specified type to attempt to recruit.

The value of multiplying the factors of 3√2 * 2√5 * 8√18 is 288√5 in radical form

The expression is given as:

3√2 * 2√5 * 8√18

Multiply the integers

3√2 * 2√5 * 8√18 = 3 * 2 * 8 *√2 *√5 * √18

This gives

3√2 * 2√5 * 8√18 = 48 *√2 *√5 * √18

Multiply the radicands

3√2 * 2√5 * 8√18 = 48 *√5 * √36

Take the square root of 36

3√2 * 2√5 * 8√18 = 48 *√5 * 6

Multiply 48 by 6

3√2 * 2√5 * 8√18 = 288√5

Hence, the value of 3√2 * 2√5 * 8√18 is 288√5

Answer:

A. -3/2

Step-by-step explanation:

» Concepts

The slope of a line describes the steepness, or the change in y over the change in x of a line. The formula to find the slope, given two points, is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where we put in the x- and y-coordinates of the two points.

» Application

In this case, we're given two points: (-2, 5) and (4, -4). We have to find the slope of the line containing them, so we must use our aforementioned formula.

» Solution

Therefore, the answer is A. -3/2.

The set A is the set of sports balls that are spherical, the complement of set A is {baseball}.

Given that the universe set U = {baseball, basketball, football, tennis ball, soccer ball, volleyball}.

Sets in mathematics, are simply a collection of distinct objects forming a group. A set can have any group of items, be it a collection of numbers, days of a week, types of vehicles, and so on. Every item in the set is called an element of the set.

The set A is the set of sports balls that are spherical

Set A={basketball, football, tennis ball, soccer ball, volleyball}

So, the complement of Set A is {baseball}

Because, a baseball infield is in the shape of a square, with each base at a vertex.

Hence, the set A is the set of sports balls that are spherical, the complement of set A is {baseball}.
