This cuboid's total surface area measured 5cm, 4cm, and 6cm is 120 cm³.

The surface area of a solid item is a measurement of the entire area occupied by the object's surface. The total surface area includes the base(s) and the curving portion. It is the whole area covered by the object's surface. The total area of a form with a curved surface and base is the sum of the two areas. The total surface area is obtained by summing all the areas on the surface: the areas of the object's base, top, and lateral surfaces (sides).

Here,

total surface area of cuboid,

You are given the line, y=-2x-5. This line is in slope-intercept form, y=mx+b, where m is the slope (or gradient) and b is the y-intercept.

The gradient of the given line is -2 and the y-intercept is -5.

The value of x in the given 45-45-90 triangle is 9.89.

The given triangle is a right-angled triangle which can be solved using the Pythagoras theorem. The Pythagoras theorem states that the square of the hypotenuse is equal to the sum of the square of the base and the square of the perpendicular. This theorem can be applied to all right-angled triangles.

In the given triangle, we have been told that the length of both legs is 7. Now, after applying the theorem -

= 7²+7² = H²

= 49 + 49 = H²

= 98 = H²

= √98 = H

= 9.89 = H

Hence, this is the value of x.

AutoCAD uses two different coordinate systems. Your working plane's angle is determined by the World Coordinate System (WCS) and User Coordinate System (UCS).

In order to guarantee that everything lines up with the center of a file in a real-world location, the WCS should always be utilized as the geometry reference. The screen can be oriented to a location using the UCS. The file originated from the WCS. The WCS can't be moved from its current location.

Drawing elements will use the rotating coordinate system if a user coordinate system is set, however, the WCS can always be changed. A "User Coordinate System" (UCS) specifies the angle of the XY plane in which you are operating. The XY plane is rotated when a user coordinate system is defined, making it easier to work with alternative orientations.

The proportional relation is y= 2.2x

What is proportion?

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

Neena counts 11 beats in 5 seconds

So, x=11 and y=5

Using the proportionality

y = k x

k= y/x

k= 11/5

k= 2.2

Hence, the proportional relation is y= 2.2x

Answer:

2.2

Step-by-step explanation:

1. COP= constant of proportionality

What does that mean? This is how much of something you need for the variables to be proportional no matter their value. For example, if you pay 1.99 for 1 gallon of gas but then 30 dollars for 2 gallons at the same gas station, it doesn't make sense. You need to pay $3 for 2 gallons, and so on.

2. How do we find COP?

K is going to represent the constant of proportionality (COP), what we are solving for. Your equation should be k=b/a.

3. B is what comes first in the ratio, and is second. They said "beats to minutes" so beats= b and minutes= a

Answer:

  2.5 or 3.5

Step-by-step explanation:

You have an x-cm square and a rectangle ℓ cm by 3 cm. Together, they have a total perimeter of 32 cm. You want the length ℓ and the area S in terms of x, and you want to know the values of x that make the area be 30.25 cm².

The length of the wire is 32 cm. This is the sum of the perimeters of the square and the rectangle.

  P = 4s +2(l+w)

  32 = 4x + 2(ℓ +3) . . . . . . . . substitute given values

Solving the equation for ℓ, we have ...

  16 = 2x +ℓ +3 . . . . . . . . . divide by 2

  ℓ = 13 -2x . . . . . . . . . . . subtract 3+2x

The total area of the two figures is the sum of the area of the square and that of the rectangle:

  S = x² +3ℓ

  S = x² +3(13 -2x) . . . . . . substitute for ℓ

  S = x² -6x +39 . . . . . . . simplify

For an area of 30.25 cm, we require ...

  30.25 = x² -6x +39

  -8.75 = x² -6x . . . . . . . . . . subtract 39

  0.25 = x² -6x +9 . . . . . . . complete the square

  ±0.5 = x -3 . . . . . . . . . . . . take the square root

  x = 3 ± 0.5 = {2.5, 3.5}

The total area is 30.25 cm² for x = 2.5 or x = 3.5.

If Lori made a fraction of 3/4 of a sketch, she spent 9 minutes sketching.

A portion of something is called a fraction. When the numerator and denominator are divided, a number is represented mathematically as a quotient. In a simple fraction, both are integers. A complex fraction contains a fraction in either the numerator or denominator. In a proper fraction, the numerator is smaller than the denominator.

Given the equation

Enlarge the shape by scale factor 3.

To expand a form, multiply all of its lengths by the scaling factor. The scale factor indicates how much larger the shape will be. For example, increasing a form by a scale factor of two means that all of its sides will be twice as long. This rectangle measures one square broad by two squares long.

To employ a center of enlargement, we must draw lines from the center of enlargement to the original shape’s vertices. These are known as ray lines. E.g. Triangle ABC has been expanded by a scale factor of 2 around an expansion point O.

Drawing 2 cm 5 times in a straight line will give us a 10 cm line segment after dilation.

Dilation is the process of increasing an object's size without altering its form. Depending on the scale factor, the object's size may rise or shrink. A square of side 5 units can be widened to a square of side 15 units using dilation math, but the square's form doesn't change.

A dilation is a function f from a metric space M into itself that, for any locations x, y in M, fulfills the identity d=rd, where d is the distance between x and y and r is a positive real integer. Such a dilatation is a resemblance of the space in Euclidean space.

Meaning of Dilation in Math. Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. However, there is a variation in the shape's size.

A loop is a programming construct that allows a set of instructions to be repeated until a certain condition is met.

Function is a relation between input and output values, where each input is related to exactly one output. A function is a mathematical rule that assigns a unique output to each input. It is a process that produces a specific result from given inputs. Functions are used in many areas of mathematics, including algebra, calculus and geometry.

The loop can be used to execute a set of instructions multiple times, or it can be used to iterate over a collection of items such as an array. Loops are an important part of programming, as they allow for efficient and concise code.

Loops are especially useful when it comes to dealing with large datasets. For example, if you wanted to loop through an array of 100 elements, you could do so by writing a single loop statement. This allows you to quickly and easily process large amounts of data without having to write separate instructions for each element. Similarly, loops can be used to iterate over a collection of items such as a linked list or a hash table, making it easier to deal with complex data structures.
