Answer:
C. 160,000
Step-by-step explanation:
Given that the measurements obtained for the interior dimensions of a rectangular box are 200 cm by 200 cm by 300 cm.
Also given that each of the three measurements has an error of at most 1 cm
COnsider the worst case where each dimension is increased by 1 cm
Then we measure the dimensions as 201 , 201 and 301
So volume would be measured as
cubic cm
Actual volume of the box =
cubic cm
Difference maximum possible = 160701 cubic cm
Out of the five options given option C is nearest to this value
So answer is
C. 160,000
Queremos tener todos los variables del mismo typo en un lado así que vamos a mover la -x a la izquierda, y el 15 a la derecha.
15 + 3x = 21 - x
+x +x
————————
15 + 4x = 21
-15 -15
———————
4x = 6
— —
4 4
X = 1.5 para ver si es correcto puedes tratar de poner 1.5 en lugar de la x y te saldrá una ecuación correcta :), déjame saber si tienes preguntas espero que eso hizo sentido.
