Answer:
20
Step-by-step explanation:
The real answer is 20.428, so rounded it's 20
If an item is $15.20 is increased by 125% (34.20) it would be about $34.20 before we subtract 10% (3.42)....we arrive at the end cost of $30.78.
wholesale price would be 15.20
Answer:
8x^2 + 5y + 1
Step-by-step explanation:
1 + x^2 - 3 + 2y + 7x^2 + 3 + 3y
group like terms
= x^2 + 7x^2 + 2y + 3y + 1 - 3 + 3
add similar items
= 8x^2 + 2y + 3y + 1 - 3 + 3
add similar items
= 8x^2 + 5y + 1 - 3 + 3
= 8x^2 + 5y + 1
is the expression Devonte used the change of base formula to approximate log Subscript 8 Baseline 25.
Given that, Devonte used the change of base formula to approximate log Subscript 8 Baseline 25.
We need to determine the expression did Devonte use.
<h3>What is the formula of change of base formula?</h3>
The change of base formula says
. It means to change the base of a logarithm logb b a, we just use division
where these logarithms can have any positive number as a base.
Now, log Subscript 8 Baseline 25 

Therefore,
is the expression Devonte used the change of base formula to approximate log Subscript 8 Baseline 25.
