Answer:
29.79
Step-by-step explanation:
In constructing an inequality, you need to know the following:
1. What don't we know? How many songs can be bought? So, let x be the numbers of songs.
2. What do we know? Each songs costs $2 plus a fee for using the artist's site of $5.
3. Is there more than 1 possible solution? Yes, because there is enough money left if she only bought 1 song.
The meaning of no more than $40 means it must not exceed $40, $40 or less, or only $40.
So, song + fee can't be more than $40 and song + fee could equal to $40.
Therefore, song + fee for using an artist's site less than or equal to $40.
Final Answer: 2x+5 <= 40
Answer:
A
Step-by-step explanation:
10 squared + 24 squared = 26 squared :)
A) We can use the linear approximation to estimate the amount of time it takes. We're given that the linear approximation to t at the point x = 0 is t(x) ≈ L(x) = d(1–(x/60)). If it drives 84 miles at 62 mi/hr, we'll plug 84 in for d and 62 – 60 = 2 in for x to approximate the amount of time it takes.
L(2) = 84(1 – 2/60) = 81.2 minutes
So the answer for part a is 81.2 minutes.
b) Exact time = Distance/Speed = 84/62 = 1.35 hours, which is equivalent to 1.35 * 60 = 81.3 minutes.
Answer:
<em>The retail price of the jeans was $81.25.</em>
<em>Second Choice: $81.25.</em>
Step-by-step explanation:
Mrs. Jimenez paid $65 for some jeans.
She intended to sell them at her store by marking their price up by 25%.
We have to add 25% to $65:
25 * $65 / 100 = $16.25
$65 + $16.25 = $81.25
The retail price of the jeans was $81.25.
Second Choice: $81.25.
