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.
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

A circular swimming pool has a radius of 3.5 m Liz is placing a piece of rope around the edge of the pool if Liz has exactly enough rope, which measurement is the closest to the length of the piece of rope in meters
Answer:
the length of the piece of rope in meters is 22
Step-by-step explanation:
The computation of the length of the piece of rope in meters is shown below:
= 2πr
= 2 × 3.14 × 3.5m
= 21.98
= 22 meters
Hence, the length of the piece of rope in meters is 22

The figure is a triangle that is divided into two parts. Angle A and angle E are right angles, and the measure of angle F is 30°. What is the measure of angle C?
Complete the steps below to solve the problem using equations.
Part A
Let the variable g represent the measurement of angle G. Write an equation that you can use to solve for g.
Answer:
MAKE SURE TO READ THE QUESTION. MINE IS SOMEWHAT DIFFERENT>
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????
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.
A rectangular prism is 4 inches long, 3 inches wide and 8 inches tall . Eli packs the prism with unit cubes to find the volume. Abby uses a formula to find the volume
Answer:
[tex]V=96\ inch^2[/tex]
Step-by-step explanation:
Given that,
A rectangular prism is 4 inches long, 3 inches wide and 8 inches tall.
We need to find the volume of the rectangular prism. The formula for the volume of prism is given by :
[tex]V=lbh\\\\V=4\times 3\times 8\\\\V=96\ inch^2[/tex]
So, the volume of the prism is equal to [tex]96\ inch^2[/tex].

Suppose that the weight (in pounds) of an airplane is a linear function of the total amount of fuel (in gallons) in its tank. When graphed, the function gives a line
with a slope of 5.7. See the figure below.
With 46 gallons of fuel in its tank, the airplane has a weight of 2162.2 pounds. What is the weight of the plane with 18 gallons of fuel in its tank?
Answer:
total plane weight with 82gallons fuel is 2424.80 lbs.
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?
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 placsHence the statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074
