Answer:

cost of materials - the value of all things needed to create the good or service

opportunity cost - the value of a product given up to produce or obtain another product

fixed cost - costs that are not affected by the level of production

sunk cost - past costs that cannot be recovered

marginal cost - change in total cost that arises when the quantity produced changes by one unit

Answer: The initial elevation of the plane was 8.75 miles.

Step-by-step explanation:

Suppose that the initial elevation of the plane is E.

Then the plane descends 3.5 miles.

Then the new elevation of the plane will be:

E - 3.5 miles.

Now, we know that the new elevation of the plane is 5.25 miles, then:

E - 3.5 miles = 5.25 miles.

Now we need to solve this for E.

To solve this, we can add the same number to both sides of the equation, so we can add 3.5 miles to both sides to get:

(E - 3.5 miles) + 3.5 miles = 5.25 miles + 3.5 miles

E + (3.5 miles - 3.5 miles) = 5.25 miles + 3.5 miles

E = 8.75 miles.

The initial elevation of the plane was 8.75 miles.

On Monday Mark ran for a distance of  [tex]\frac{53}{15}[/tex] miles and on Tuesday he ran for a distance of  [tex]\frac{106}{15}[/tex] miles.

What is a fraction ?

A fraction is used to represent a portion or component of a whole. The numerator and denominator are its two parts.

It is given that on Monday , Mark ran [tex]1\frac{1}{3}[/tex] miles to school and then [tex]2\frac{1}{5}[/tex] miles to his grandmother's house.

This meant the total distance he ran on Monday can be calculated by adding both the distances he travelled on the particular day i.e.,

=  [tex]1\frac{1}{3}[/tex] miles + [tex]2\frac{1}{5}[/tex] miles

= [tex]\frac{4}{3}[/tex] miles + [tex]\frac{11}{5}[/tex] miles

Now , to add two fractions we need to equal denominator.

= [tex]\frac{20+33}{15}[/tex]

= [tex]\frac{53}{15}[/tex] miles

Now , on Tuesday he ran twice as much as Monday. So , the distance he ran on Tuesday is equal to :

= 2 × [tex]\frac{53}{15}[/tex] miles

= [tex]\frac{106}{15}[/tex] miles

Therefore , on Monday Mark ran for a distance of  [tex]\frac{53}{15}[/tex] miles and on Tuesday he ran for a distance of  [tex]\frac{106}{15}[/tex] miles.

Answer:

D

Step-by-step explanation:

Answer:

See answers below

Step-by-step explanation:

Given the following ratios. We are to express them in their simplest forms

15:12

= 15/12

= (3*5)/(3*4)

= 3/3 * 5/4

= 5/4

b) 42:1

= 42/1

= 42

Given that  2:x :: 4:6​

2/x = 4/6

Cross multiply

4x = 2*6

4x = 12

x = 12/4

x = 3

Hence the value of x is 3

Answer:

3( -8 + 1) = 3( -8) + 3(1)

Step-by-step explanation:

That is distributive property

Answer:

3(-8+1)=(3(-8)+(3(1)

Step-by-step explanation:

In this case, distributive property is when a number or you could call it integer, multiplies with another set of number inside parentheses ().

Your answer was wrong, because 6 x 7=42, and that's not equal to the other side of numbers.

The top one is addition, so that's a no.

The second one's not exactly in the form you want it to be for it to be the same as the left side.

The third one shows distributive property in two ways, which give you the same result, so that would be the correct answer.

Hope this helped!

If you understood, and my answer helped, please mark me brainliest.

Answer:

Step-by-step explanation:

Distributive property can be defined as :

a(b+c)= (a*b) + (a*c)

Answer:

1. All real numbers

2. All real numbers

3.x>=0

4.y>=-6

Step-by-step explanation:

The domain of the sum of the functions is x ≥ 0 and the range of the function is y ≥ -6.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a functions g(x) and k(x)

g(x) = x - 6

The domain of the function:

D: x ∈ (-∞, ∞) or

All real numbers.

k(x) = √x

The domain of the function k(x) is x ≥ 0

The range of the function k(x) is y ≥ 0

The sum of the functions:

= g(x) + k(x)

= x - 6 + √x

= x + √x - 6

The domain of the function is x ≥ 0

The range of the function is y ≥ -6

Thus, the domain of the sum of the functions is x ≥ 0 and the range of the function is y ≥ -6.

Answer:

m<B = 93°

Step-by-step explanation:

Based on the inscribed quadrilateral theorem, the opposite angles of a cyclic quadrilateral are supplementary.

Thus:

m<B + m<D = 180°

Substitute

m<B + 87° = 180°

m<B = 180° - 87°

m<B = 93°

Answer:

[tex]\Huge\boxed{D.14.6}[/tex]

Step-by-step explanation:

Hello There!

We can solve for x using trigonometry

More specifically the law of sines

In the image you can see that a side length divided by sin(its opposite angle) is equal to another side length divided by sin(its opposite angle)

so to find x we use this equation

[tex]\frac{x}{sin59} =\frac{17}{sin90}[/tex]

step 1 multiply each side by sin 59

now we have

[tex]x=\frac{17sin59}{sin90}\\x = 14.6[/tex]

so we can conclude that x = 14.6
