Answer: Quadrant 4
Step-by-step explanation:
Answer:
El contador que señala 840 registra de 3 en 3.
Step-by-step explanation:
Existe un truco para determinar si un número es múltiplo de 3, si la suma de sus dígitos es 3 o uno de sus múltiplos, entonces el número es un múltiplo de 3. En consecuencia, corresponde al contador eléctrico que registra de 3 en 3 y el otro contador eléctrico sería el que registra de 5 en 5.
Primer contador: 840
12 es un múltiplo de 3, por tanto, este contador es el que registra de 3 en 3.
Segundo contador: 560
11 no es un múltiplo de 3. Asimismo, todo número que sea múltiplo de 5 termina en 5 o 0, entonces este contador es el que registra de 5 en 5.
El contador que señala 840 registra de 3 en 3.
Answer: Transitive Postulate of Inequality (last option)
Explanation:
Let's say we have a vacation where we go from City A, to City B, then to City C. We can use the notation . If all we cared about was the first and last cities, then we basically say taking a shortcut so to speak.
This analogy is useful to describe the transitive property.
The equality version is where if we had a = b and b = c, then a = c.
The inequality version is where if we had a < b and b < c, then a < c. In this case, c = 2.
In a sense, its like linking together metal chains. A leads to B which leads to C. So we can just jump from A to C.
It might help to draw out a number line and pick values for a and b like a = 0 and b = 1. That way you can see how a < b, b < c and a < c all tie together.
Answer:
It will take 8 seconds.
Step-by-step explanation:
To solve this, you would put it in ratio form (at least, that's what our class did). So 9 quarts of water in 6 seconds would be 9 quarts/6 seconds. You need to find the unit rate after that, so to find that you'd divide 9 by 6. This would give you 1.5 quarts per second.
Now all you need to do is find out what to multiply 1.5 by to be able to get to 12. The number you get will be how many seconds it takes for the hose to emit 12 quarts.
1.5 x <u> </u> = 12
1.5 x <u> 8 </u> = 12
8 is the number of seconds it takes for the hose to emit 12 quarts of water. To write this in ratio form, it would be
<u>12 quarts</u>
8 sec
(it's supposed to be written like a fraction, but there's no way to do that here.) Hope this helped!
