La ecuación de la recta es y = 1.2x + 0, o simplemente y = 1.2x. Y el precio en euros de 10 dólares es de 12 €.

La ecuación de la recta que nos da el precio en euros, y, de x dólares se puede hallar utilizando la fórmula de la pendiente de una recta, que es m = (y2 - y1) / (x2 - x1). En este caso, los puntos dados son (3, 3.6) y (7, 8.4).

Primero, calculamos la pendiente de la recta:
m = (8.4 - 3.6) / (7 - 3)

m = 4.8 / 4

m = 1.2

Luego, utilizamos la fórmula de la ecuación de la recta, y = mx + b, para encontrar el valor de b. Podemos utilizar cualquiera de los puntos dados para esto. Usaremos el punto (3, 3.6).

3.6 = 1.2(3) + b
3.6 = 3.6 + b
b = 0

Por lo tanto, la ecuación de la recta es y = 1.2x + 0, o simplemente y = 1.2x.

Esta ecuación nos da el precio en euros, y, de x dólares. Si queremos encontrar el precio en euros de una cierta cantidad de dólares, simplemente sustituimos el valor de x en la ecuación y resolvemos para y. Por ejemplo, si queremos encontrar el precio en euros de 10 dólares, sustituimos x = 10 en la ecuación:

y = 1.2(10) = 12

Por lo tanto, el precio en euros de 10 dólares es de 12 €.

The number 19 have only two factors. They are 1 and 19. So it is a prime number. The statement is true.

Prime numbers are the numbers having only two factors, 1 and the number itself. There are some conditions that should be satisfied if they are counted as prime numbers.

It must be greater than 1.

It must be a natural number, not a decimal fraction or negative number.

It must have only two factors.

It must not be a product of any two numbers other than 1 and the number.

So a number which is not divisible by any other number than 1, can be called a prime number. All other numbers are composite numbers.

So 19 is not divisible by any other numbers. So it is a prime number.

The equation tan(30°) = 5/b can be used to solve for b. The solution has been obtained by using trigonometry.

What is trigonometry?

The study of the sides, angles, and connections of the right-angle triangle falls under the purview of the branch of mathematics known as trigonometry.

We are given a right angled triangle, with angle BCA = 90° and angle CAB = 30°. Also, the length of side BC is 5 centimeters, the length of BA is 10 centimeters, and the length of CA is b.

Using trigonometry,

We know that tan theta = opposite side/ adjacent side

So,

⇒tan θ = 5/b

Here, θ = 30°

So,

⇒tan 30° = 5/b

Hence, the equation tan(30°) = 5/b can be used to solve for b.

Along with addition, subtraction and division, multiplication is one of the four basic arithmetic operations. In mathematics, multiplication means the repeated addition of groups of the same size. As we can see, 3+3 is the same as 2×3. When we multiply two numbers, the answer is called the product. The number of objects in each group is called the multiplicand, and the number of such equal groups is called the multiplier. In our case, 3 is the multiplier, 2 is the multiplier, and 6 is the product. Also, the product of 2× x , where x is any integer, is known as two times of x. We need to calculate the value for 2 times -3. Thus,

We need 124 grams of Na2O to produce 160 grams of NaOH

A balanced chemical equation is an equation where the number of atoms of each type in the reaction is the same on both reactants and product sides.

Let us first convert 160 grams of NaOH to moles using its molar mass. The molar mass of NaOH is:

Na = 22.99 g/mol

O = 15.99 g/mol

H = 1.01 g/mol

Molar mass of NaOH = 22.99 + 15.99 + 1.01 = 40.00 g/mol

Number of moles of NaOH = mass / molar mass = 160 g / 40.00 g/mol = 4.00 mol

Since the reaction requires 2 moles of NaOH for every 1 mole of Na2O, we need half as many moles of Na2O as NaOH.

Therefore, we need: 1/2 x 4.00 mol = 2.00 mol of Na2O

Finally, we can convert moles of Na2O to grams using its molar mass:

Na = 22.99 g/mol

O = 15.99 g/mol

Molar mass of Na2O = 22.99 + 2(15.99) = 61.98 g/mol

Mass of Na2O = number of moles x molar mass = 2.00 mol x 61.98 g/mol = 123.96 g

Therefore, we need 124 grams of Na2O to produce 160 grams of NaOH

The conversion of 70°F is equal to 21.1°C.

A temperature unit developed from the SI (International System of Units) is Celsius (symbol: °C).

Prior to the adoption of the metric system, Fahrenheit (symbol: °F) was a commonly used measurement of temperature.

To convert 70°F (degrees Fahrenheit) to Celsius (°C), you can use the following formula:

°C = (°F - 32) / 1.8

Substituting 70°F for °F in the formula, we get:

°C = (70 - 32) / 1.8

Simplifying the calculation, we get:

°C = 38 / 1.8

°C ≈ 21.1

Therefore, the conversion of 70°F is nearly equal to 21.1°C.

Answer:

56%

Step-by-step explanation:

The probability of snow on Tuesday is 20%, which means the probability of no snow on Tuesday is 100% - 20% = 80%.

Similarly, the probability of snow on Wednesday is 30%, which means the probability of no snow on Wednesday is 100% - 30% = 70%.

The probability that it will not snow on either day is the product of the probabilities of no snow on Tuesday and no snow on Wednesday:

(80%)(70%) = 56%

The height of the silo is approximately 81 meters to the nearest meter.

One of the most basic areas of mathematics, trigonometry has a wide range of applications. The study of the relationship between the sides and angles of the right-angle triangle is essentially the focus of the field of mathematics known as "trigonometry."

Let's draw a diagram to visualize the situation. We have a right triangle with the transit (T), the silo (S), and a point on the ground (G) where the surveyor is standing. The angle of elevation of the silo from the surveyor's position is 52º, and we know the distance TG = 65 m and the height of the transit HT = 1.7 m. We want to find the height of the silo, which is HS.

             HT = 1.7 m

Using trigonometry, we have the following equation:

tan(52º) = HS / TG + HT

Solving for HS, we get:

HS = (TG + HT) * tan(52º)

= (65 + 1.7) * tan(52º)
