The song lasts 3 minutes and 27 seconds. If Rasmus' beloved has to get home before the song is over, and rides a bike at an average speed of 15 km / h, how far away must her work be from their home?
Set up an equation that describes the problem where x is the distance between home and work.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

From the question :

Duration, time, t = 3 minutes, 27 seconds = (3 * 60) + 27 = 207 seconds

Average speed = 15 km/h = (15*1000) /3600 = 4.16666 m/s

Let distance = x

Recall:

Speed = distance / time

Distance = speed * time

x ≤ (speed * time)

x ≤ (4.16666 * 207)

x ≤ 862.5 m

x ≤ (862.5 / 1000) km

x ≤ 0.862.5 km

Step-by-step explanation:

The sum of the angle measurements in a triangle is 180°. If e, f, and g are the measurements of angles E, F, and G, respectively, e + f + g = 180°.

Angle E is a right angle, so e is 90°. From the given information, f is 30°. Substitute the values of e and f in the equation to solve for g : 90° + 30° + g = 180°.

Alguien me pude decir una adivinanza o historia q la solución sea una ecuación de segundo grado completa????

Answers

Answer:

Una ecuación de segundo grado completa es algo como:

y = a*x^2 + b*x + c

Un problema tipico que usa ecuaciones de este tipo es algo que nos haga multiplicar dos términos como h*(x + k) y n*(x + j)

Donde h, k, n, y j son números reales.

Entonces planteemos el siguiente caso.

"Juan tiene una tabla rectangular, de tal forma que su largo es (x + 3cm), y el ancho es igual a dos veces su largo, si sabemos que el área de esta tabla es 95 cm^2 ¿cuál es el valor de x?"

Acá hay que recordar que para un rectángulo de largo L y ancho W, el área es:

A = L*W

En este caso tendremos:

L = (x + 3cm)

Y el ancho es dos veces eso, entonces:

W = 2*(x + 3cm)

Entonces el area de esta tabla se escribirá como:

A = (x + 3cm)*2*(x + 3cm)

Ahora solo tenemos que expandir eso:

A = 2*x^2 + 12cm*x + 18cm^2

Ahora sabemos que el area de esta tabla es 95cm^2

Entonces:

95cm^2 =  2*x^2 + 12cm*x + 18cm^2

0 = 2*x^2 + 12cm*x + (18cm^2 - 95cm^2)

0 = 2*x^2 + 12cm*x - 77 cm^2

Esta es una ecuación de segundo grado completa, la cual deberiamos resolver para encontrar el valor de x como se nos pide en el problema.

Peter determined the area, in square miles, of a piece of land using his calculator. The result of his calculation is displayed on his calculator in scientific notation as 7.4e – 4.
Which statement is true of the area of the piece of land?

Answers

Answer:

The true statement of the area of the piece of land is;

(C) It is between 0.0007 and 0.007 square mile

Step-by-step explanation:

Using scientific notation, we have the value of a measurement presented as follows;

c × 10ⁿ = ce±n

Where;

c = The coefficient number, less than 10

en = 1 × 10⁺ⁿ

e-n = 1 × 10⁻ⁿ

Therefore, the given number, 7.4 e - 4, can be expressed as follows;

7.4 e - 4 = 7.4 × 10⁻⁴ = 0.00074

0.00074 ≈ 0.0007 and we have;

0.0007 < 0.00074 < 0.007

The correct option is therefore that it is between 0.0007 and 0.007 square mile

The statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074

The standard form for writing scientific notation is given as A * 10^n

Given the result of his calculation displayed on his calculator in scientific notation as 7.4e^-4.

Writing this as a standard value will give:

7.4e^-4 = 0.00074 (Note that the decimal point was shifted back in four placs

Hence the statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074
