The surface area of the prism represented by the net diagram is 154.5 cm^2

The area of a shape is the amount of space on the shape

For most regular quadrilaterals, you multiply the side lengths to determine the area

The given parameter is in the figure

In the figure, we have the net of a rectangular prism

From the net of a rectangular prism, we have the following dimensions

Length = 8 1/2 cm

Width = 4 1/2 cm

Height = 3 cm

The surface area of the prism is then calculated as

Surface area = 2 * (Length * Width + Length * Height + Width * Height)

Substitute the known values in the above equation

So, we have the following equation

Surface area = 2 * (8 1/2 * 4 1/2 + 8 1/2 * 3 + 4 1/2 * 3)

Evaluate the products

So, we have the following equation

Surface area = 2 * (38 1/4 + 25 1/2 + 13 1/2)

Evaluate the sum

So, we have the following equation

Surface area = 2 * 77 1/4

Evaluate the products

So, we have the following equation

Surface area = 154.5

Hence, the surface area of the prism is 154.5 cm^2

Answer:

y = -x + 7

Step-by-step explanation:

let's use the first numbers as an example.

x=1 and y=6

now to get this we need to find the difference between the two numbers and we can do this by simply doing - 1 + 7 = 5

therefore making the answer y = -x + 7

Each person will sell 8 shirts if 56 shirts were sold

Mandy and 6 of her teammates each sold an equal number of shirt

Mandy is one person, let add 1 plus six to get the total number

1 + 6

= 7

The total number of shirts sold is 56 shirts

Since there are 7 people, the number of shirt that each person will sell can be calculated by dividing 56 by 7

= 56/7

= 8

Hence 8 shirts will be sold by each person

Answer:

2 apples and 4 bananas

Step-by-step explanation:

Given info:

Question given:

Determine the number of apples, x, and the number of bananas, y, that Juan bought.

Solution:

Since, we know that;

apples = x

bananas = y

Cost of each apple = $1 & Cost of each banana = $ 0.50

Total = 6

The equation that represents the following information:

x + y = 6

x + 0.5y = 4

We can multiply the top equation by -1 so it becomes -x -y = 6

-x - y = 6

x + 0.5y = 4

Now, we can use elimination to cancel out the x.

-0.5y = -2

y = 4

Because y=4, x must be 2 since x+y=6. So,

x = 2 and y = 4

Which means;

Juan bought 2 apples and 4 bananas.

Step-by-step explanation: i used a calculator

The horizontal shift will be the term that is subtracting the angle, in this case: -3pi/4= B .

To be a function, a relation can't have more than 1 value of 'y' for the same value of 'x'

For example, if you have points (3,7) and (3,-6) does not represent a function but points (3,7) and (-3,7) does.

In this problem, none of the graphed pairs have 2 or more values of 'y' for a single value of 'x'. They are all different, so yes, this relation is a function

The inverse equation of the function is f'1(x) = 3 + √x

Inverse functions are the opposite of an original equation. This means that for a function f(x), the inverse of the function f(x) is f-(x)

The function f(x) is given as

f(x) = (x - 3)^2, x ≥ 3

As a general rule, we start by writing f(x) as a variable (say f(x) = y).

So, the equation of the function becomes

y = (x - 3)^2

The next step is to switch/swap the positions of x and y in the equation

The equation becomes

x = (y - 3)^2

Make y the subject of the formula in the equation

The equation becomes

y = 3 + √x

Express as an inverse function

f'1(x) = 3 + √x

Hence, the equation of the inverse function is f'1(x) = 3 + √x

Ratio of length of cell A to the length of cell B will be 20 : 1.

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

Length of cell A = 4 x 10⁻⁵

Length of cell B = 0.000002 = 2 x 10⁻⁶.

Now,

Length of cell B into scientific notation = 2 x 10⁻⁶

Hence, The ratio of the length of cell A to cell B =  4 x 10⁻⁵ / 2 x 10⁻⁶

                                                                          = 2 x 10⁻⁵⁺⁶

                                                                          = 2 x 10¹

The description of the one transformation that maps ∆ABC to ∆A'B'C' is a rotation counterclockwise, 90 degrees, with the center at the origin

A rotation transformation can be described as the angular motion of a rigid, geometric figure around a point

The vertices on the triangle ∆ABC are;

The vertices on the triangle ∆A'B'C' are;

The rotation of a point A(x, y), 90° counterclockwise about the origin gives the point A'(-y, x)

The reflection of a point (x, y) across the y–axis gives the point A'(-x, y)

Therefore;

The coordinates of the vertices of∆ABC following a 90° counterclockwise rotation gives;

A(-5, -2) → A'(2, -5)

B(-7, -4) → B'(4, -7)

C(-5, -5) → C'(5, -5)

Therefore;

The transformation that maps ∆ABC to ∆A'B'C' is therefore a rotation of 90° counterclockwise about the origin

The addition, subtraction, multiplication and division of the two functions are 4 · x + x¹⁰, 4 · x - x¹⁰, 4 · x¹¹ and 4 / x⁹, respectively.

In functions there are two fundamental operations (addition, multiplication) and two derivate operations (subtraction, division). In this problem we must look for the following definitions:

Addition

(f + g)(x) = f(x) + g(x)

Subtraction

(f - g)(x) = f(x) - g(x)

Multiplication

(f · g)(x) = f(x) · g(x)

Division

(f / g)(x) = f(x) / g(x), for x ≠ 0.

If we know that f(x) = 4 · x and g(x) = x¹⁰, then the expression behind the operations are, respectively:

Addition

(f + g)(x) = 4 · x + x¹⁰

Subtraction

(f - g)(x) = 4 · x - x¹⁰

Multiplication

(f · g)(x) = (4 · x) · x¹⁰ = 4 · x¹¹

Division

(f / g)(x) = (4 · x) / x¹⁰ = 4 / x⁹

Total cost is given by the function $(20 + 10x)

What is a function?

A function in mathematics from a set X to a set Y assigns exactly one element of Y to each element of X.  The set X is referred to as the function's domain, and the set Y is referred to as the function's codomain.  Al-Biruni and Sharaf al-Din al-Tusi, two Persian mathematicians, are responsible for the earliest known treatment of the concept of function. Initially, functions represented the idealised relationship between two varying quantities. A planet's position, for instance, depends on time. In the past, the idea was developed with the infinitesimal calculus at the end of the 17th century, and the functions that were taken into consideration until the 19th century were differentiable (that is, they had a high degree of regularity).

Total cost is given by the function $(20 + 10x)

Step-by-step explanation:

x = age of one of the twin boys

when they had together 21 years of age,

Bill was x years old

Ross was x years old

Mark was x+3 years old

so, we have

x + x + (x + 3) = 21

3x + 3 = 21

3x = 18

x = 6

Bill and Ross were 6 years old.

Mark was 6+3 = 9 years old.

Mark was born in 1990.

1990 + 9 = 1999

so, it was 1999 when they had together 21 years of age.

The scale of the drawing is expressed as, 1 inch : 2.5 yards.

A scale factor describes to what size an original image has been reduced or enlarged. If the scale factor of an enlargement is 2, it means every side lengths of the original image is increased times two to get the new image after enlargement.

On the other hand, if the reduction was done using a scale factor of 0.5 or 1/2, it means the size of the original image was reduced by half to get the new side lengths of the new image.

The scale factor of a scale drawing = dimension of new image/corresponding dimension of original image.
