sorry for the poor quality picture

The system of equations that represents the given scenario is a + c = 20, 15a + 10c = 225 and the solution to the system of equations is a = 5 (adults) and c = 15 (children).

Two or more expressions with an Equal sign is called as Equation.

Let a represent the number of adult tickets and c represent the number of children's tickets.

The total number of tickets purchased is 20, so we have:

a + c = 20

The cost of an adult ticket is $15 and the cost of a children's ticket is $10. The total cost of the tickets is $225, so we have:

15a + 10c = 225

Therefore, the system of equations that represents the given scenario is:

a + c = 20

15a + 10c = 225

Now let us solve a and c values by using substitution method.

a=20-c

Now substitute in equation 15a + 10c = 225

15(20-c)+ 10c = 225

300 - 15c + 10c = 225

-5c = -75

c = 15

Substituting c = 15 into the first equation, we get:

a + 15 = 20

a = 5

Therefore, the system of equations that represents the given scenario is

a + c = 20, 15a + 10c = 225 and the solution to the system of equations is a = 5 (adults) and c = 15 (children).

Answer:

Your answer would 107.

Step-by-step explanation:

180 minus 73 equals 107.

:)

Answer:

A equals 105 degrees, option 2

Step-by-step explanation:

7x + 5x gives 180. 7x and 5x lie on a line so they form a linear pair. Their sum equals 180 degrees:-

7x + 5x = 180

12x = 180

x = [tex]\frac{180}{12}[/tex]

x = 15

Since x is 15, we can find the lengths of 7x and 5x.

7x would be 7 x 15 = 105

5x would be 5 x 15 = 75

'A' is equal to 7x since they are vertically opposite angles.

Since 7x is 105 degrees, then A would be 105 degrees as well.

Answer:

(x + 7)^2 = 64

Step-by-step explanation:

x^2 + 23x – 19 = 9x - 4

x^2 + 23x - 9x = -4 + 19

x^2 + 14x = 15 = 0

Completing the square:

(x + 14/2)^2 - (14/2)^2 = 15

(x + 7)^2 - 49 = 15

(x + 7)^2 = 64

Answer:

The angles have measurements 36, 72, 108, 144, and 180.

Step-by-step explanation:

Pentagon has 5 sides and 5 angles.

The amount of triangles formed by choosing one vertex and drawing from that vertex to every nonadjacent vertex is 3.

3(180)=540 which is the sum of the angles in a pentagon.

So since the ratio is 1:2:3:4:5, that means the angles are 1x,2x,3x,4x, and 5x.

We have the equation 1x+2x+3x+4x+5x=540 to solve.

15x=540

Divide 15 on both sides:

x=540/15

x=36

1x=36

2x=72

3x=108

4x=144

5x=180

The angles have measurements 36, 72, 108, 144, and 180.

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying [tex]\sqrt{54}[/tex]

[tex]\sqrt{54}[/tex]

= [tex]\sqrt{9}[/tex] × [tex]\sqrt{6}[/tex]

Then

2[tex]\sqrt{6}[/tex] - 5[tex]\sqrt{54}[/tex]

Answer:

11.25

Step-by-step explanation:

Since AB and CD  are parallel, ∠D is congruent to ∠A and ∠C is congruent to ∠B.  Therefore the two triangles are similar by the AA postulate.  Now, the corresponding sides are in proportion

Since AE ↔ DE and AB ↔ CD

So, AE/CD = AB/CD

AE/5 = 9/4

AE = 9(5)/4

     = 45/4  = 11.25

From the figure, we can notice that : Surface area of the pyramid is equal to Sum of the area of the square and Sum of the areas of 4 triangles.

We know that : Area of a square is given by : Side x Side

Given : Side of the square = 3 cm

⇒  Area of the square = 3 x 3 = 9 cm²

We know that : Area of the triangle = 1/2 x Base x Height

From the figure, We can notice that, Base of each triangle = 3 cm and height of the each triangle = 3 cm

⇒ Area of one triangle = 1/2 × 3 × 3 = 4.5 cm²

Surface area of the pyramid = Surface of the square + Surface area of the 4 triangles

⇒  Surface area of the pyramid = 9 cm² + 4(4.5) cm²

⇒  Surface area of the pyramid = 9 cm² + 18 cm² = 27 cm²

Answer : Surface area of the pyramid = 27 cm²

Answer:

Step-by-step explanation:

Answer:

Option A

Step-by-step explanation:

As shown in the figure ABC,

AC = Length of the ladder

BC = Distance between the base of the ladder and the wall

AB = Distance from the top of the ladder and the base of the wall

By applying Pythagoras theorem in the given right triangle ΔABC,

AC² = AB² + BC²

(32)² = h² + (6.5)²

h² = 1024 - 42.25

h = √(981.75)

h = 31.33

h ≈ 31 feet

Therefore, Option A will be the correct option.

Answer:

Discount = $138

Sale price = $552

Step-by-step explanation:

Discount =  20% of 690

Sale price  = 100% - 20% = 80% of 690

Discount)

20% = 0.2

0.2 x 690 = 138

Discount = $138

Sale price)

Method 1:

80% = 0.8

0.8 x 690 = 552

Sale price = $552

Method 2:

We know the discount = $138

So subtract the discount from the original price:

690 - 138 = 552

Sale price = $552.

Given:

A square base pyramid with base length 6 cm and the slant height is 4 cm.

To find:

The lateral surface area of the given square pyramid.

Solution:

The lateral surface area of the given square pyramid is equal to the areas of 4 congruent triangles with base 6 cm and height 4 cm.

Area of a triangle is:

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

So, the area of one triangle or one side of the given pyramid is:

[tex]A_1=\dfrac{1}{2}\times 6\times 4[/tex]

[tex]A_1=\dfrac{24}{2}[/tex]

[tex]A_1=12[/tex]

Now, the lateral surface area of the given square pyramid is 4 times the area of one triangle.

[tex]LA=4A_1[/tex]

[tex]LA=4(12)[/tex]

[tex]LA=48[/tex]

Therefore, the lateral surface area of the given square pyramid is 48 cm².
