Respuesta:
B. Generalmente, el tamaño del zapato de un estudiante no influye en la cantidad de libros recolectados.
Explicación paso a paso:
To find the total distance Isla walked, multiply 3/4 of a mile by 2 since it was a round trip. The result is 1.5 miles.
Let X denote <span>the baby’s weight.
Let y represent </span>the doctor’s weight.
Let z stand for the nurse’s weight.
From the equations: x + y = 78 implies y = 78 - x
and x + z = 69 gives z = 69 - x
then we have x + y + z = 142
Substituting y = 78 - x and z = 69 - x into the equation x + y + z = 142
x + y + z = 142
x + 78 - x + 69 - x = 142
-x + 147 = 142
-x = -5
x = 5
Conclusion
<span>the baby’s weight was 5 kg</span>
To demonstrate:
The angle drawn within a semicircle forms a right angle.
According to the inscribed angle theorem, the angle θ that is inscribed in a circle is half of the measure of the central angle. Thus, in a semicircle, the inscribed angle is half of 180 degrees, resulting in 90 degrees, which is a right angle. <span />
