Answer:

One adult ticket is $16, and one child ticket is $4

Step-by-step explanation:

Let A be the price for an adult ticket

Let C be the price for a child ticket

First write out the equations based on the given information

A = 4C

A + C = 20

Since we know that A is the same as 4C, you can sub in 4C into A + C = 20

4C + C = 20

5C = 20

C = 4

You can now sub in C = 4 into A + C = 20

A + 4 = 20

A = 16

Therefore, an adult ticket costs $16, and one child ticket is $4

Step-by-step explanation:

We know that x = -3

So,

-3² + 2 x -3

9 + 2 x -3

Answer:

X= -40/3

Step-by-step explanation:

2x= 7/8x-15

1. Combine the multiplied terms into just one fraction: 2x= 7x/8-15

2. Find the common denominator: 2x= 7x/8 + 8(-15)/8

3. Combine those fractions with the common denominator(as shown from step 2, above): 7x+8(-15)/8

4. Multiply the numbers: 8 times -15= 120

Given the equation system:

You can find the solution to this equation system using the subtitution method.

Since the first expression is written in terms of y, you can replace it into the second expression and calculate for x

-Distribute the multiplication on the parentheses term:

-Simplify the x-terms, by solving the operation between them

-Pass 21 to the right side of the equation by applying the opposite operation to both sides of the equal sign

-Finally, divide both sides of the equation by 34 to determine the value of x

Now that we have determined the value of x, we can replace it into the first equation to calculate the value of y:

We have that BC = BA and m

We will have that the angle DAB and BAC are supplementary, therefore:

DAB + BAC = 180°

And replecing the value of DAB, we will get:

120 + BAC = 180 => BAC = 60.

By theorem the angles that oppose equal sides are equal, therefore: ACB = 60.

From this, we will also get that ABC = 60.

And B = 90.

Triangle ABD will be a scalene triangle.

Triangle DBC will be a rectangle triangle.

The equation of the line will be y = 2x + 3. Then the correct option is B.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

From the graph, two points are taken as (0, 3) and (1, 5). Then the equation of the line is given as,

(y - 3) = [(5 - 3) / (1 - 0)](x - 0)

Simplify the equation, then we have

y - 3 = 2x

y = 2x + 3

The equation of the line will be y = 2x + 3. Then the correct option is B.

Chris will have $7810 at the end of 12 years in his account if the simple interest rate is 3.5%.

According to the question,

We have the following information:

Chris invested $5,500. The investment had a simple interest rate of 3.5%. And he plans to leave the investment alone for 12 years.

Now, we know that the following formula is used to find the simple interest on an investment:

Interest = principal*rate*time/100

Principal = $5500

Rate = 3.5

Time = 12 years

Interest = (5500*3.5*12)/100

Interest = $2310

Now, the total amount in his account will be:

5500+2310

$7810

Hence, Chris will have $7810 at the end of 12 years in his account if the simple interest rate is 3.5%.

The measurement of ∠STU is 20°.

Define Angle

When two rays are connected at their endpoints, they form an angle in geometry. We refer to these rays as the angle's sides or arms.

Components of an Angle

An angle is composed of the arms and the vertex as its two basic components:

Given, ∠STU = [tex](\frac {1}{4} x+8)[/tex]°

∠UTV = x+2°

Given, that the line TV bisects ∠STU,

∠STV = ∠UTV

Substitute their values,

[tex](\frac {1}{4} x+8)[/tex]° = x+2°

Calculating,

[tex]\frac{1}{4}x-x[/tex] = 2-8

[tex]-\frac{3}{4}x[/tex] = -6

x = [tex]-6*(-\frac{4}{3})[/tex]

x = 8

So, we know that:

∠STU = ∠STV + ∠UTV

          =  [tex](\frac {1}{4} x+8)[/tex]° +( x+2°)

          =  [tex](\frac {5}{4} x+10)[/tex]

Now, substitute the value of x,

∠STU =  [tex](\frac {5}{4} )*8[/tex]°+10°

          = 10° + 10°

          = 20°

Therefore, the measure of ∠STU is 20°.

Notice that to find the final result, we add 0.4 +1 and then multiply by 18237.

In order to find how many boxed they need, first they need to know the area they will have to cover:

In order to find it, we have find the total area of the rectangle and take off the area of the House and the area of the shed:

We know that all those areas are rectangles, their area are found multiplying their sides lenght:

House area = 5m x 16m = 80m²

Shed area = 3m x 3m = 9m²

Since the lateral side of the total area is

5m + 16m + 5m = 26m, then

Total area = 26m x 50m = 1300m²

Then, the area they need to cover is

total area - house area - shed area = 1300m² - 9m² - 80m²

= 1211m²

Since the seed they select covers 375 m² per box, in order to find how many boxes they need, we just need to divide the area they are going to cover with this number:

1211m² ÷ 375 m² = 3.229

We round it to 4 boxes as indicated.

Answer: they need to buy 4 boxes of seeds

The equation of a sine function given in accordance with the given specifications is y = 3sin[(2/3)x + π/8) - 2.

The trigonometric functions (also called circular functions, angle functions) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

Given is the following specifications for a sine wave -

Amplitude: 3

Period: 3π

Phase Shift: π/8

Vertical Shift: -2

The general equation for sine wave is -

y = A sin(ωx + Ф) + k

Now, we know -

ω = 2π/T

ω = 2π/3π

ω = 2/3

And -

A = 3

Ф = π/8

k = - 2

y = 3sin[(2/3)x + π/8) - 2

Therefore, the equation of a sine function given in accordance with the given specifications is y = 3sin[(2/3)x + π/8) - 2.

Addition:

The act of combining two or more items is known as addition. The process of computing the sum of two or more numbers in mathematics is called addition. It is a fundamental mathematical procedure that is frequently used in daily life. When we work with money, figure out our food bills, or figure out the time, we frequently employ addition. One-digit numbers can be added simply for solving addition problems, however for bigger numbers, we divide the numbers into columns using their corresponding place values, such as ones, tens, hundreds, thousands, and so on.

We have a right triangle where x is the hypotenuse, we know that one angle measures 20° and the adjacent cathetus to that angle measures 12 units.

Then we can use the trigonometric relation:
