You can buy 3 apples at HEB for $1.08. You can buy 5 of the same apples at Kroger’s for $1.15. The apple purchased at HEB are the better buy. True or False? show work

Answers

Answer:

False

Step-by-step explanation:

1.08/3=0.36 for an apple at HEB

1.15/5=0.23 for an apple at Kroger

Melanie is going to a book sale. All the books are priced for $2 each, including sales tax. She can spend no more than $15. Which inequality represents the number of books Melanie can buy?

Answers

Answer:

x ≤ 7

Step-by-step explanation:

Let the cost of each book be $2

Let the amount of book she can buy be x

If she can spend no more than $15

Amount of book she can buy≤ Total amount/cost of each book

Amount of book she can buy ≤ $15/$2

Amount of book she can buy ≤ 7.5

x ≤ 7.5 OR x ≤ 7

Hence the required inequality is x ≤ 7. Less than or equal to was used since she can't spend more than $15

Answer:

x ≤ 7

Answers

Answer: 1000 mL

Step-by-step explanation:

Answer: 1000 Milliliters

Step-by-step explanation:

Convert 1 Liters to Milliliters

To calculate 1 Liter to the corresponding value in Milliliters, multiply the quantity in Liters by 1000 (conversion factor). In this case, we should multiply 1 Liters by 1000 to get the equivalent result in Milliliters:

1 Liters x 1000 = 1000 Milliliters

1 Liter is equivalent to 1000 Milliliters.

Quick conversion chart of milliliters to liters

1 milliliters to liters = 0.001 liters

10 milliliters to liters = 0.01 liters

50 milliliters to liters = 0.05 liters

100 milliliters to liters = 0.1 liters

200 milliliters to liters = 0.2 liters

500 milliliters to liters = 0.5 liters

1000 milliliters to liters = 1 liters
