All the parts are solved below.

What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.

Given are the equations -

1. 2a=4.6

2. b+2=4.6

3. c÷2=4.6

4. d−2=4.6

5. e+38=2

6. 18f=3

7. g÷85=1

We have -

[1] -

2a = 4.6

a = 2.3

[2] -

b + 2 = 4.6

b = 2.6

[3] -

c ÷ 2 = 4.6

c x 1/2 = 4.6

c = 4.6 x 2

c = 9.2

[4] -

d − 2 = 4.6

d = 6.6

[5] -

e + 38 = 2

e = - 36

[6] -

18f = 3

f = 3/18

f = 1/6

[7] -

g ÷ 85 = 1

g x 1/85 = 1

g = 85

Therefore, all the parts are solved above.

Find the missing measure (x) of the triangle.

Answers

Answer:

x = 34 degrees

Step-by-step explanation:

all angles of a triangle add up to 180 degrees

x = 180-90-56 = 34 degrees

180 - 90 is 90 then 90 - 56 is 34 so X = 34

Answers

Multiply everything then put the x numbers in one side and constants in the other. Then divide by the number of x

Answer:

x = - 2

Step-by-step explanation:

3(5x + 2) - 7(3x - 4) = (5 - 9x)2

15x + 6 - 21x + 28 = 10 - 18x

34 - 6x = 10x - 18

-12x = 24

x = -2

The answer would be 54 since there is only 180 degrees in a triangle so you subtract 90 and 36 from 180. You get 54
Answer: 54

Explanation: There are only 180 degrees in every triangle. We know that the box in the corner symbols 90 degrees and we have information that the other degree is 36.

90 + 36 = 126
180 - 126 = 54

x = 54

What is the surface area of the figure?

Answers

9514 1404 393

Answer:

  B.  24 cm²

Step-by-step explanation:

The formula for the area of a triangle is ...

  A = 1/2bh

Here, you have a base of 4 cm and a height of 3 cm, so the area is ...

  A = (1/2)(4 cm)(3 cm) = 6 cm²

__

The rectangle on the right is 3+1.5 = 4.5 cm high, and 8 -4 = 4 cm wide. Its area is ...

  A = WH

  A = (4 cm)(4.5 cm) = 18 cm²

The total area is the sum of the areas of the parts:

  total area = triangle area + rectangle area

  total area = 6 cm² + 18 cm² = 24 cm²

Answer:

I believe that it would be better to use the second scale, or 1ft to 500ft.

Step-by-step explanation:

If you used the first scale(1in to 10ft) then you would have a 75in model, or 6.25ft, this would be to big to display on your desk. If you used the second then your model would be about 1.5in which all though is small it would be better for display.

Answer:

1 inch

Step-by-step explanation:

1 foot = 500 feet

1 inch = 10 feet

^ if you do 12 x 10 it equals 120, which is less than 1 foot = 500.

But, if you want it a big it would be 1 foot = 500.
