The answer to this is 5x-12
5
1.25 hours = 75 miles = 1/4 of 60 is 15 (of the 1.25)
75/15 (miles per gallon)
Answer:
The values are a=-6 and b=18.
Step-by-step explanation:
A Geometric sequence is given by the formula
for all , where r ≠ 0 is the common ratio and is the first term of the sequence
.
In this problem we know that m=
2, is the second term of the sequence and is the third term.
First we need to find the general form of the sequence, we can use the fourth term and the value of to find r.
We replace and in the formula , then we have
.
Therefore the general form of the sequence is for all .
To find the value of a, we replace n=2 in our formula, so
.
To find the value of b, we replace n=3 in our formula, so
.
Answer:
A
Step-by-step explanation:
Entropy is the measure of how disordered a system is. The higher the entropy, the more disordered. Whenever we go from a solid to liquid to gas, that's considered an increase in entropy because the molecules are moving faster and in more random directions. Eliminate B and D
Meanwhile, notice that we see the +34.89 kJ on the left side of the equation / the reactant side of the equation. This means that the reaction is endothermic because there is an input of energy. If the +34.89 kJ was on the right side / the product side, then it would be exothermic.
Thus, the answer is A.
Hope this helps!
Um....Where is the question.....or is that it
