answer:
30 > 4x + 2 and 6 books
step-by-step explanation:
- read the question and set up the inequality
- let x = number of books he can afford
30 > 4x + 2
- 30 would be on one side since that's the most he can spend
- 4x because each book is $4
- + 2 because there is a charge of $2
30 > 4x + 2
28 > 4x
7 > x
- he can afford 6 books
- it cannot be 7 because if he does buy 7 books, it would cost more than $30
Answer:
$1050
$54,600
Step-by-step explanation:
In this question, we are looking at calculating two things. We want to calculate the amount of commission made in a week and the amount made in a year.
Firstly, to calculate the amount of commission she made last week, we simply find the percentage.
Mathematically, this is equal simply to:
14% of $7,500 = 14/100 * 7500 = $1050
She made a commission of $1050 last week
Now, we are told this is the average she makes per week. We now want to calculate how much she makes per year. To do this, what we do is to multiply what she had made in a week by the number of weeks in a year.
The number of weeks in a year is 52. The amount she made is just 52 * $1050 = $54,600
Solve:-
1 quart = 4 cups
8 × 4 = 32
8 quarts = 32 cups
32, 1 cup servings.
If we look at our SOHCAHTOA rule:
cos(x) = adj/hyp
The adjacent side of N is 36, and the hypotenuse is 39.
Therefore:
cos(N) = 36 / 39
