Answer:
La familia de Gonzalo ha despilfarrado 15,768 litros de agua.
Step-by-step explanation:
Dado que Gonzalo observa que el grifo del lavabo gotea luego de un año, y el goteo se produce una velocidad de una gota por segundo y cada gota contiene 0.5ml de agua, para determinar cuántos litros de agua ha despilfarrado la familia de Gonzalo desde que ellos se dieron cuenta de la avería se debe realizar el siguiente cálculo:
1 año = 365 dias x 24 horas x 60 minutos x 60 segundos
0.5 x 60 x 60 x 24 x 365 = X
30 x 60 x 24 x 365 = X
1800 x 24 x 365 = X
43,200 x 365 = X
15,768,000 = X
15,768,000 / 1000 = X
15,768 = X
Por lo tanto, la familia de Gonzalo ha despilfarrado 15,768 litros de agua.
Answer:
d. $137,604
Step-by-step explanation:
The amortization formula is good for this. It tells you the principal P that must be invested to support payments of A each year for t years when the interest rate is r:
P = A(1 -(1 +r)^-t)/r
P = $12,000(1 -1.06^-20)/0.06 ≈ $137,639.05
The closest answer choice is $137,604.
The answer to your question is 120
Answer:
X=-7
Step-by-step explanation:
When "subtracting" negatives it's basically like adding them together, but the numbers get farther away from 0 going left... The equation could look like
-7 - 2 = -9 <em>or </em>-7 + (-2) = -9 :)
3/4 divided by 8 can be done by doing 3/4 times 1/8 (which is the reciprocal of 8). When multiplied through, your answer should be 3/32. It cannot be simplified any further, so each student will get 3/32 of the cake. Hope this helps :)
