Answer:
y
15.5
Step-by-step explanation:
The Total Amount taken to the store by Jerome = $20
He buys a book worth $4.50
Let y be the most he could spend on CDs
Since he is spending on books and CDs, the amount spent cannot be more than total sum he has, therefore:
y+$4.50
20
This is because he could spend either less than $20 or exactly $20
y
20-4.50
y
15.5 is the inequality to find the most he could spend on CDs.
Take both mixed numbers (a whole number plus a fraction) and turn them into improper fractions ( a numerator (top number) bigger than the denominator (bottom number). To do this, multiply the denominator by the whole number, and add the result to the numerator.
5 5/8 will become 45/8
1 1/2 will become 3/2.
Area is length* width, so width would be Area/ length. So 45/8 is the area and 3/2 is the length. Now you have (45/8)/(3/2). To divide fractions, take the second fraction and flip the numerator and denominator, forming the reciprocal (2/3). Now multiply 45/8 and 2/3
The result is 90/24, and simplifying would get 15/4, or 3 3/4. This is the width(or length)
This is simple , minus 50 from 100 and that gives you 50 left . then divide that by 2 and that gives you 25 . so the minimum number of sales required is 25 . hope this helps :)<span />
Answer:
7.1
Step-by-step explanation:
- Find mean
- For each number you subtract the mean and square the result.
- Work out the mean of those squared differences and find square root of that.
