Answer:
Trey lives 384 feet.
Step-by-step explanation:
Let the average rate be represented by s, and the distance by d.
speed =
⇒ distance = speed x time
i.e d = s x t
On his first trip,
d = s x 8
d = 8s ............ 1
on his trip home, the average rate was 16 miles per hour faster, so that;
d = (s + 16) x 6
d = 6s + 96 ............ 2
Equation 1 and 2, we have;
8s = 6s + 96
8s - 6s = 96
2s = 96
s = 48
The average rate is 48 miles per hour.
Thus from equation 1 (also equation 2 can be used),
d = 48 x 8
= 384
Therefore, Trey lives 384 feet from the mountains.
Answer: The answer would be 950 international minutes. Only if assuming that this is in one month since the question doesn't give much detail.
Step-by-step explanation:
X would be used to represent the number of months.
25+0.10x=120
0.10x=95
950 international minutes used
<h2>
Answer:</h2>
True
<h2>
Step-by-step explanation:</h2>
A counterexample is a special type of example that is an exception to a general rule, law, proposition or statement. Hence if we prove that then this is a counterexample for the expression . Thus:
So we observe that the equation is not fulfilled because . In conclusion:
<u><em>A counterexample for the expression sin(x)+cos(x)=1 is 45° </em></u><u><em>is true!</em></u>
