He'll save 3 dollars if he buys 60 mouth guards in packs of 10 which is 6×14.50 = 87
Whereas
4×22.50 = 90
Answer: Yes, they are proportional
Step-by-step explanation:
Each side was multiplied by 2
Answer:
Step-by-step explanation:
The easiest way to tell if a relation is a function is to look at the x coordinates. If none of them are the same in the set, then the relation is a function. If any of the x values are used more than once in the set, it is only a relation. This set uses -3 two times, so it is a relation.
For this problem we must set up some fractions in an equality. First, we put number of people in the numerator and number of hours in the denominator. After this we can plug in 24 to the numerator of the first fraction and 4 to the denominator of the first fraction (24/4). We then set the two fractions equal to each other and put 18 in the numerator of the second fraction and the variable X and the denominator of the second fraction (18/x). Lastly we cross multiply and then divide leaving X alone. This will be our answer. Therefore the answer is 3 hours.
Answer:
La opción correcta es;
B.2 m 0,25 m
Step-by-step explanation:
Por lo que los parámetros dados son;
La distancia horizontal de la rampa = 4 my la altura de la rampa = 0,5 m
Por lo tanto, tenemos la pendiente de la rampa = La relación entre la altura y la distancia horizontal de la rampa dada de la siguiente manera;
La pendiente de la rampa = 0.5 / 4 = 1/8
De las opciones dadas, tenemos;
Opción A. La pendiente de la rampa = 0,20 / 1 = 1/5
Opción B. La pendiente de la rampa = 0,25 / 2 = 1/8
Opción C. La pendiente de la rampa = 1/2
Opción D. La pendiente de la rampa = 1,5 / 3 = 1/2
Por tanto, la opción que tiene la misma pendiente que la rampa A es la opción B
