<h3>Answer:</h3>
63 liters
<h3>Explanation:</h3>
The amount of fuel used per day is ...
... (1 tank - 2/3 tank)/(6 days) = (1/3 tank)/(6 days) = (1/18) tank/day
Then the amount of fuel used after 6+11 = 17 days is
... (17 days)×(1/18 tank/day) = 17/18 tank
and the amount remaining is ...
... (1 tank -17/18 tank) = 1/18 tank = 3 1/2 liters
To find the tank size, we can multiply this result by 18:
... 1 tank = 18×(3 1/2 liters) = 63 liters
We are asked to simplify the given mathematical expression a5*3b9*6a. To do this, we need to follow the law of exponent that if it is same variable being multiplied we can add the power. In this problem, variable "a" existed twice so we can add powers of a5 to 6a such as:
6a(5+1) *3b9
6a6*3b9 , then multiply constants which are 6 and 3
18a6b9
The answer is 18(a^6)(b^9).
Answer:
Option B is correct.
The expression which is equivalent to is;
Explanation:
Given the equation: for all values of n.
The quadratic equation in this form;
First find two numbers that multiply to give ac and add to give b.
From the given equation;
a =1 , b = 26 and c =88
then,
the two number that multiply to give ac =88 is, 22 or 4
and they add up to give b=26 (i.e 22+4)
Now, rewrite the middle term i.e 26n with 22n and 4n , we have
Now, factor the first two terms and last two terms,
we see that is common to both terms so, we have;
Therefore, the expression is equivalent to
Check:
(n+4)(n+22) = = [ True]
