Its AA similarity theorem

Step-by-step explanation:

correct on edge 2021

The triangles ABC and EDC are similar by AA similarity theorem.

Two triangles are said to be similar if their corresponding sides are in equal ratio and corresponding angles are congruent.

Given is a proof of showing △ ABC ~ △ EDC

The proof is as follows :-

           Statement                                                Reason

            AB ∥ DE                                                     Given

         ∠ ACB = ∠ ECD                           definition of vertical angles  

         ∠ BDE ≅ ∠ DBA                   alternate interior angles are congruent

         △ ABC ~ △ EDC                                 AA similarity theorem

AA similarity theorem :-

AA similarity theorem states that when two corresponding angles of two triangles are found congruent then the triangles are similar by AA similarity theorem.

Hence, the missing reason is AA similarity theorem.

The perimeter of triangular sign is 12x+3

Step-by-step explanation:

Length of side1 of triangle = x inches

Length of side2 of triangle = 4x-5 inches

Length of side3 of triangle = 7x+8 inches

We need to find perimeter of triangular sign.

The formula used is: [tex]Perimeter \ of \ triangle = Sum \ of \ all \ three \ sides[/tex]

Now, finding perimeter of triangular sign:

[tex]Perimeter \ of \ triangle = Sum \ of \ all \ three \ sides\\Perimeter \ of \ triangle = x+4x-5+7x+8\\Perimeter \ of \ triangle = x+4x+7x-5+8\\Perimeter \ of \ triangle = 12x+3[/tex]

The perimeter of triangular sign is 12x+3

Answer:

8 large glasses can be filled by a large bottle.

Step-by-step explanation:

First we calculate the volume of a small bottle:

Now we calculate the volume of a small glass:

" A small bottle fills 6 small glasses with no juice left over.", this means that

Then we calculate the volume of a large glass:

Finally we divide the volume of a large bottle by the volume of a large glass:

So 8 large glasses can be filled by a large bottle with juice left over.

Answer:

3 berries

Explanation:

Opportunity costs for the Orange group:

Opportunity cost of pumping 1 gallon of water = 3/1 = 3 berries

Opportunity cost of picking 1 berry = 1/3 = 0.333 gallons of water

Opportunity costs for the Yellow group:

Opportunity cost of pumping 1 gallon of water = 8/2 = 4 berries

Opportunity cost of picking 1 berry = 2/8 = 0.25 gallons of water

Opportunity cost for both groups combined:

Opportunity cost of pumping 1 gallon of water = 3 berries (Orange group should pump water since opportunity cost is lower)

Opportunity cost of picking 1 berry = 0.25 gallons of water (Yellow group should pick berries since opportunity cost is lower)

Opportunity costs are the extra costs or benefits lost resulting from choosing one investment or activity over another alternative. In this case, people can either pump water or pick berries, but they cannot do both at the same time. When they are pumping water, the opportunity cost is the amount of berries that they will not be able to collect, and vice versa.

Answer:

7 recipes could be made with [tex]2\frac{1}{3}[/tex] cups of sugar.

Step-by-step explanation:

Quantity of sugar required for a recipe [tex]=\frac{1}{3}[/tex] cups

Quantity of sugar required in a pantry [tex]=2\frac{1}{3}[/tex] cups

Here,

[tex]2\frac{1}{3}=\frac{7}{3}[/tex]

So,

Quantity of sugar required in a pantry [tex]=\frac{7}{3}[/tex] cups

Number of recipes that could be made  [tex]=\frac{\frac{7}{3} }{\frac{1}{3} } =7[/tex]

Therefore, 7 recipes could be made with [tex]2\frac{1}{3}[/tex] cups of sugar.

Answer:

The sum of the first 12 terms of the sequence is 2703.673096

Step-by-step explanation:

The nth term of a geometric progression is a(n) = [tex]ar^{n-1}[/tex], where

The sum of n terms of the geometric progression is s(n) = [tex]\frac{a(r^{n}-1)}{r-1}[/tex]

∵ The third term of a geometric progression is [tex]\frac{63}{4}[/tex]

∴ a(3) = [tex]\frac{63}{4}[/tex]

∵ a(3) = ar²

→ Equate its two right sides

∴ ar² =  [tex]\frac{63}{4}[/tex] ⇒ (1)

∵ The sixth term is [tex]\frac{1701}{32}[/tex]

∴ a(6) = [tex]\frac{1701}{32}[/tex]

∵ a(6) = a[tex]r^{5}[/tex]

→ Equate its two right sides

∴ a[tex]r^{5}[/tex] =  [tex]\frac{1701}{32}[/tex] ⇒ (2)

→ Divide (2) by (1)

∴ r³ = [tex]\frac{27}{8}[/tex]

→ Take ∛  for both sides

∴ r = [tex]\frac{3}{2}[/tex] = 1.5

→ Substitute the value of r in (1) to find a

∵ a(1.5) = [tex]\frac{63}{4}[/tex]

∴ 1.5a = 15.75

→ Divide both sides by 1.5

∴ a = 10.5

→ Let us find the sum of the first 12 terms

∵ n = 12, a = 10.5, and r = 1.5

→ Substitute them in the rule of the sum above

∵ s(12) = [tex]\frac{10.5(1.5^{12}-1)}{1.5-1}[/tex]

∴ s(12) = 2703.673096

∴ The sum of the first 12 terms of the sequence is 2703.673096

Answer:

b is correct

Step-by-step explanation:

The product of the functions M(x) and n(x) is x³+ 4x².

To find the product of the two functions, M(x) = x² + 4x and n(x) = x, we need to multiply them together.

So, (mn)(x) = M(x) × n(x)

Substituting the given functions:

(mn)(x) = (x² + 4x) × x

Now, we can simplify the expression by applying the distributive property of multiplication:

(mn)(x) = x × x² + x × 4x

Simplifying further:

(mn)(x) = x³ + 4x²

Therefore, the product of the functions M(x) and n(x) is x³+ 4x².

Answer:

The present age of the artifact is 1,600 years

Step-by-step explanation:

let the present age of the artifact = x

let the present age of the book, = y

x = 4y ---- equation (1)

x + 200 = 3(y + 200) ------equation (2)

x + 200 = 3y + 600

substitute in the value of x into the equation;

4y + 200 = 3y + 600

4y - 3y = 600 - 200

y = 400

Then, x = 4 x 400

x = 1,600 years

Therefore, the present age of the artifact is 1,600 years
