one day reeva baked several dozen muffins. the next day she made 8 dozen more muffins. if she made 20 dozen muffins in all, how many dozen did she make the first day?

Answer:

That is it's simplest form

Step-by-step explanation:

There is no coefficients that are the same

Answer:

The answer is the third

S = 16 t²

Step-by-step explanation:

* Lets study the order pairs in C to find what is the relation

  between the input (t) and the output (S)

∵ C = {(t , S): (0 , 0) , (1 , 16) , (2 , 64) , (3 , 144) , .............}

∵ (0 , 0) is the first point

∴ There is no plus or minus in the relation between S and t

∴ We refused the last answer S = 16(t + 1)² because

  if t = 0 then S = 16(0 + 1) = 16 ≠ 0

- If we chose the first answer:

∵ S = 16t  

∵ t = 0 ⇒ S = 16(0) = 0 ⇒ its right

∵ t = 1 ⇒ S = 16(1) = 16 ⇒ its right

∵ t = 2 ⇒ S = 16(2) = 32 ⇒ its wrong

∴ We refused the first answer

- If we chose the second answer:

∵ S = (16t)²

∵ t = 0 ⇒ S = (16×0)² = 0 ⇒ its right

∵ t = 1 ⇒ S = (16×1)² = 256 ⇒ wrong

∴ We refused the second answer

- If we chose the third answer:

∵ S = 16 t²

∵ t = 0 ⇒ S = (16)(0)² = 0 ⇒ its right

∵ t = 1 ⇒ S = (16)(1)² = 16 ⇒ its right

∵ t = 2 ⇒ S = (16)(2)² = 16 × 4 = 64 ⇒ its right

∵ t = 3 ⇒ S = (16)(3)² = 16 × 9 = 144 ⇒ its right

∴ every time we multiply 16 by the square of the value of t

∴ We accept the third answer

Answer:

28 miles per gallon

Step-by-step explanation:

you divide 420 by 15 to see how many miles per gallon and

420 divided by 15= 28 (gallons)

28 miles I think I’m not sure but just divide 15 into 420 and you should get the answer.

Answer:

The wall is 3 ft high and 5 ft long.

Step-by-step explanation:

Recall:  Area of the rectangular wall is A = (length)(height).

Let the height be represented by h.  Then the length is represented by h + 2.

The formula A = (length)(height) then becomes A = h(h+2) = 15 ft², which, written in the standard form of a quadratic equation, is h² + 2h - 15 = 0.

Let's solve this last equation for h using completing the square:

h² + 2h - 15 = 0 becomes h² + 2h + 1 -1 - 15 = 0, or (h + 1)² = 16.  Taking the square root of both sides, we get:

h + 1 = ±4, which is equivalent to h = 3 and h = -5.  Discard the negative result.  Then h = 3 and w = 3+2 = 5.

The wall is 3 ft high and 5 ft long.  Its area is (3 ft)(5 ft) = 15 ft²

The height and the length of the rectangular wall is 3 feet and 5 feet respectively.

Area of a rectangle = 15 square feet

Length = x feet

Height = (x - 2) feet

Area of a rectangle = height × length

15 = x × (x - 2)

15 = x² - 2x

set to quadratic equation

x² - 2x - 15 = 0

x² - 5x + 3x - 15 = 0

x(x - 5) + 3(x - 5) = 0

(x + 3)(x - 5) = 0

x + 3 = 0 or x - 5 = 0

x = -3 or x = 5

The length of a rectangle cannot be negative

Therefore,

Length = x feet

= 5 feet

Height = (x - 2) feet

= 5 - 2

= 3 feet

Answer:  A proportional relationship is one in which two quantities vary directly with each other.  To Decide whether two quantities are in a proportional relationship, is by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.

that is true if that's 1/3n=7/12

if it's 1/3n-7/12 then the first step is to equal it to zero

Yes, the second step in solving 1/3n = 7/12 is to divide both sides of the equation by 1/3.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation 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. In a fraction say (x/y), [y] is called denominator.

We have the equation -

(1/3)n = (7/12)

We have -

(1/3)n = (7/12)

Dividing both sides by (1/3), we get -

[(1/3)/(1/3)]n = [7/12 x 3]

n = 7/4

Therefore, yes, the second step in solving 1/3n = 7/12 is to divide both sides of the equation by 1/3.

Answer:

length of x is 50 yards

Step-by-step explanation:

Pythagorean Theorem:  a^2 + b^2 = c^2

30^2 + 40^2 = c^2

900 + 1600 = c^2

2500 = c^2   need to solve for c, square root both sides

50 = c

The length of the diagonal is 50 yards. The diagonal of a rectangle divides the rectangle into two right-angled triangles. Thus, by applying the Pythagoras theorem we can able to find the length of the diagonal.

The theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle) and the algebraic notation, [tex]a^2 + b^2 = c^2[/tex].

The diagonal of a rectangle divides the rectangle into two halves of right-angled triangles.

The length and breadth of the rectangle are 40 yards and 30 yards.

The diagonal x divides the rectangle. So, it becomes a common hypotenus for the two right-angled triangles.

So, applying the Pythagoras theorem.

x^2 = (40)^2 + (30)^2

     = 1600 + 900

     = 2500

Thus, the value of x is 50 yards.

Therefore, the length of the diagonal is 50 yards.

Answer:   A. Line segment

Step-by-step explanation:

A line is a one-dimensional geometric straight -undefined figure which has no thickness or depth . It extends infinitely in both directions.  

A line segment is a part of a line having end-points on both the sides.

It has only length therefore, it is one dimensional.

Thus , the objects is considered to be one-dimensional because it has length but no width or height is a line segment.

The triangle is 2-dimensional , point has no-dimensions,  and cube  is 3-dimensional.

A line segment is the correct answer, as in mathematics it is considered one-dimensional because it only has length but no width or height. It extends in one direction, unlike a triangle and a cube, which have more dimensions. The point does not have length.

In mathematics, a line segment is considered to be one-dimensional as it only possesses a property of length but no width or height. This means it only extends in one direction, often represented on a number line. In comparison, other options presented such as a triangle, point or cube have other dimensions involved. Specifically, a triangle falls in two dimensions as it has both length and width; a cube is a three-dimensional object possessing length, width, and height; and a point, though it lacks all three dimensions, is not accurate as it doesn't have length, which is the key criterion in the question.

Step-by-step explanation:

2/3 (x+6) = -18

x+6 = -27

x = -33

Answer:

Multiply by 3

2(x + 6) = -18*3

2(x + 6) = -54    

Remove the brackets

2x + 12 = - 54

Subtract 12 from both sides

Using the tangent function with the given angle of elevation and distance to the tower, we can calculate that the height of the tower is approximately 106.1 feet, which is answer C.

This is a question about trigonometry, specifically using tangent ratios. Given that the angle of elevation from Mindy to the top of the cell phone tower is 75 degrees and Mindy is standing 28 feet from the base of the tower, we need to find the height of the tower. The tangent of an angle in a right triangle is defined as the opposite side (the height of the tower in this case) divided by the adjacent side (the distance from Mindy to the tower).

Using the tangent function gives us: Tan(75) = height / 28. Multiplying both sides by 28 gives us the height: height = 28*Tan(75). Calculating this gives us the height of the tower, which is approximately 106.1 feet, therefore Option C is correct.
