The number of red balls to the number of green balls is 3 : 2

The distribution of the balls is given as:

6 red, 4 green, 2 yellow and 3 blue balls

The number of red balls to the number of green balls is represented as:

Ratio = Red : Green

So, we have:

Ratio = 6 : 4

Simplify

Ratio = 3 : 2

Hence, the number of red balls to the number of green balls is 3 : 2

Step-by-step explanation:

Answer:

See below ~

Step-by-step explanation:

The perimeter of a figure refers to the sum of the side lengths of its edges.

Figure (a) : Triangle

⇒ P = 2a + 1 + 3a + a - 4

⇒ P = 6a - 3

⇒ P = 3 (2a - 1)

Figure (b) : Hexagon

⇒ P = 3m - 1 + 3n + n + m + 3m + 1 + 4n + m + n + 2

⇒ P = 3m + m + 3m + m + 3n + n + 4n + n + 1 - 1 + 2

⇒ P = 8m + 9n + 2

Figure (c) : Trapezoid

⇒ P = 2a + 3 + 3a - b + 2a + 2b - 4 + b + 4

⇒ P = 2a + 3a + 2a + 2b + b - b + 4 - 4 + 3

⇒ P = 7a + 2b + 3

Answer:

Q = 52.5

Step-by-step explanation:

given P is directly proportional to Q then the equation relating them is

P = kQ ← k is the constant of proportion

to find k use the condition Q = 30 when P = 40 , then

40 = 30k ( divide both sides by 30 )

[tex]\frac{40}{30}[/tex] = [tex]\frac{4}{3}[/tex] = k

P = [tex]\frac{4}{3}[/tex] Q ← equation of proportion

when P = 70 , then

70 = [tex]\frac{4}{3}[/tex] Q ( multiply both sides by 3 to clear the fraction )

210 = 4Q ( divide both sides by 4 )

52.5 = Q

By applying aritmethics and concept of capacity we conclude that the bottle containing 2 1/2 cups of apple juice contains 5 servings containing 1/2 cups each.

In this question we are dealing with capacities, capacities are an application of volumes. A bottle contains a capacity equivalent to a given quantity of cups. The number of cups is found by dividing the capacity of a bottle by the capacity of a serving:

[tex]x = \frac{\frac{5}{2}\,cups}{\frac{1}{2}\,cups }[/tex]

x = 5

The value of x will be given as for the given expression X = -1

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division

2x  +  12  =  10

2x  =  10 - 12

2x  =  -2

x    =   -1

first you distribute 2 to x and 6 which equals 2x+12=10 then you subtract 12 from 10 which equals 2x=-2 then divide -2 by 2x to see what x equals so x=-1

Answer:

x = 50°

Step-by-step explanation:

Let's make 2 equations based on the properties of the triangles :

Applying Exterior Angle Property :

Divide equation 1 by 2 :

⇒ 1/2 (x + 2∠1) = 1/2 x (2∠2)

⇒ x/2 + ∠1 = ∠2

⇒ ∠2 - ∠1 = x/2

Similarly, rewrite equation 2 :

⇒ ∠1 + 25 = ∠2

⇒ ∠2 - ∠1 = 25

From these 2 equations, we get :

⇒ x/2 = 25

⇒ x = 25 × 2

⇒ x = 50°

Answer:

|AB| = 240 km

Step-by-step explanation:

Finding ∠C :

⇒ 27° + 66° + ∠C = 180°

⇒ ∠C = 180° - 93°

⇒ ∠C = 87°

Applying the Law of Sines :

⇒ sin 66° / 220 = sin 87° / AB

⇒ 0.913545458 / 220 = 0.998629535 / AB

⇒ AB = 220/0.913545458 x 0.998629535

⇒ AB = 240.819981 x 0.998629535

⇒ AB = 240.489946

⇒ |AB| = 240 km (nearest whole kilometer)

Answer:

|AB| = 240 km (nearest km)

Step-by-step explanation:

Draw a sketch with the given information (attached).

Calculate the missing angle (shown in red on the attached diagram).

Given:

The interior angles of a triangle sum to 180°

⇒ ∠ACB + ∠CAB + ∠CBA = 180°

⇒ ∠ACB + 27° + 66° = 180°

⇒ ∠ACB = 180° - 27° - 66°

⇒ ∠ACB = 87°

Use Sine Rule for sides to calculate |AB|:

[tex]\sf \dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

[tex]\implies \sf \dfrac{|AB|}{\sin ACB}=\dfrac{|AC|}{\sin CBA}[/tex]

[tex]\implies \sf \dfrac{|AB|}{\sin (87^{\circ})}=\dfrac{220}{\sin (66^{\circ})}[/tex]

[tex]\implies \sf |AB|=\dfrac{220\:\sin (87^{\circ})}{\sin (66^{\circ})}[/tex]

[tex]\implies \sf |AB|=240.4899459...[/tex]

[tex]\implies \sf |AB|=240\:km\:(nearest\:km)[/tex]

Answer: (2, -1), or x = 2 and y = -1

By graphing:

   We can solve by graphing. See attached.

-> The solution is the point of intersection. The lines intersect at (2, -1) which means x is equal to 2 and y is equal to -1.

By substituting:

   We can solve this by substituting. It means we will substitute one equation into the other, then solve for the variables.

3x - 2y = 8

x - 2y = 4​ -> x = 2y + 4

-

3x - 2y = 8

3(2y + 4) - 2y = 8

6y + 12 - 2y = 8

4y = -4

y = -1

-

x - 2y = 4​

x - 2(-1) = 4​

x + 2 = 4

x = 2

Given that we have proven:AB =CD and BC=DA

we will be said that the A and C is the angle of 90° and we will add the letters to get the results so let's started the A+90°+ 90°+ B+C+ D=90°

A+180°+B+C+D

180°+90°

=270°

The possible coordinates of C and D are: C = (11,3) and D = (11,-5) or C = (-3,3) and D = (-3,-5)

The given parameters are:

A = (4,3)

B = (4,-5)

Perimeter, P = 30 units

Since points A and B are on the same x-coordinate, then the distance between them is:

AB = 3 - - 5

AB = 8

The perimeter of the rectangle is calculated using:

P = 2 *(AB + CD)

This gives

2 * (8 + CD) = 30

Divide by 2

8 + CD = 15

Subtract 8 from both sides

CD = 7

This means that points C and D are 7 units from points A and B, respectively.

If A = (4,3) and B = (4,-5), then the possible coordinates of C and D are:

C = (11,3) and D = (11,-5) or C = (-3,3) and D = (-3,-5)
