We created a word problem involving Sarah saving $6 each week to buy $24 art supplies, showing the multiplication equation $6 x W = $24, and used a bar model to find that Sarah needs to save for 4 weeks.
Explanation:Let's create a word problem that involves the multiplication of money and use a bar model to solve it. Imagine that a girl named Sarah is saving up to buy a special set of art supplies that costs $24. She decides to save $6 every week from her allowance. To find out how many weeks she needs to save in order to buy the art supplies, we can set up an equation using multiplication: 6 (number of dollars saved per week) x W (number of weeks) = 24 (total cost of the art supplies).
Using a bar model, we can represent the total cost as a long bar divided into smaller equal parts, each part representing $6. Counting the number of parts that add up to $24 will give us the number of weeks Sarah needs to save. This model visually supports our equation and helps us solve for W. In this case, W equals 4 because 6 dollars times 4 weeks equals the 24 dollars needed for the art supplies.

would a field with a width 75 yards and an area of 7500 square yards be within FIFA regulation?why or why not.
Yes, a field with a width of 75 yards and an area of 7500 square yards would be within FIFA regulation.
Explanation:The area of a rectangle is calculated by multiplying its length by its width. In this case, the width of the field is 75 yards and the area is 7500 square yards. To determine if the field is within FIFA regulation, we need to compare its area to the typical dimensions of a soccer field.
A typical soccer field has a length of 100-130 yards and a width of 50-100 yards. Since the field in question has a width of 75 yards, it falls within the acceptable range. Therefore, the field with a width of 75 yards and an area of 7500 square yards would be within FIFA regulation.

The ratio of dogs to cats at the pet store is 1:2. There are 15 dogs. How many cats are there?
To find the number of cats at the pet store, set up a proportion using the given ratio of dogs to cats and the number of dogs. Cross multiply to solve for the number of cats.
Explanation:To find the number of cats at the pet store, we need to use the given ratio of dogs to cats. Since the ratio is 1:2 and there are 15 dogs, we can set up a proportion to solve for the number of cats. We can write the proportion as 1/2 = 15/x, where x represents the number of cats. We can cross multiply to find x, which gives us x = 30. Therefore, there are 30 cats at the pet store.

What is a percentage?In Mathematics, a percentage is any number that is expressed as a fraction of hundred (100).
Part 14.
Mathematically, percentage increase can be calculated by using the following mathematical equation:
Percentage increase = (Final value - Initial value)/Initial value × 100
Percentage increase = (45 - 35)/35 × 100
Percentage increase = 10/35 × 100
Percentage increase = 28.57 ≈ 29%.
Part 15.
Mathematically, percentage decrease can be calculated by using the following mathematical equation:
Percentage decrease = (Final value - Initial value)/Final value × 100
Percentage decrease = (60 - 38)/60 × 100
Percentage decrease = 22/60 × 100
Percentage decrease = 36.67 ≈ 37%.
Note; 1 year is equal to 12 months.
In order to express each number of months in years, we would divide the number of month by 12;

Part 18.
Time = 3/12
Time = 1/4 years.
Part 19.
Time = 4/12
Time = 1/3 years.
Part 20.
Time = 6/12
Time = 1/2 years.

3/5 pt of juice is poured into 6 glasses.How much juice is in each glass?
Each glass contains 1/10 pt of juice when 3/5 pt of juice is evenly divided into 6 glasses.
To determine how much juice is in each glass when 3/5 pt of juice is poured evenly into 6 glasses, one must divide the total amount of juice by the number of glasses. This is a basic division problem often encountered in converting customary units in real-world situations.
First, convert the pint (pt) measurement to a more convenient unit if needed. In this case, we can keep it in pints since the division is straightforward. Next, divide the 3/5 pt of juice by 6.
Calculate the amount of juice in each glass: 3/5 ÷ 6 = 3/5 × 1/6 = 3/30 = 1/10.
Convert the fraction to pint measurement if necessary: 1/10 pt.
So each glass would contain 1/10 pt of juice.
