If we use both hoses, we fill the pool at 40 + 60 = 100 gallons per hour.
The volume of the pool is 60 * 300 = 45 * 400 = 18,000 gallons.
Hence, we need 18,000 / 100 = 180 hours.

Answers
Complete question :
Mi-Young makes 24 cups of seafood kalguksu.This is 60% of the total kalguksu she makes. Total kalguksu made is?
Answer:
40 cups
Step-by-step explanation:
Given that :
24 cups = 60% of total made
Let total kalguksu made = x
Hence,
24 cups = 0.6x
24 = 0.6x
Divide both sides by 0.6
24/0.6 = x
x = 40
Hence, total seafood Kalguksu made = 40 cups

Jordan makes two batches of cookies each week for her book club. Each batch of cookies needs 1 2/3 cups of flour. If she starts with 16 1/2 cups of flour, for how many weeks can she make cookies? Explain your solution.
Answers
Answer:
She can make cookies for 4.95 weeks
Step-by-step explanation:
2 x 1 2/3 = 3.333333333
16.5/ 3.333333333 = 4.95
Since Jordan is making two batches of Cookies per week, you need to multiply 2 by the amount of resources needed to bake one batch of cookies. So you multiply 1 and 2/3 by 2 to get the amount of resources neccesary for one week of making cookies. Then, you take the full amount of resources that she has, and divide that by the amount she uses per week, that number will give you the number needed to figure out how many weeks she has to bake cookies.
To figure out the number that is being divided to get the whole number in weeks, you would take the 16.5 cups of flour. The reason why this is, is because that Is the starting number of cups that she has. So here you would need to divide the amount you are taking from it each week. This will result in the amount of weeks that she is able to bake cookies with her flour.

Answers
Using percentages we know that 30% of students did not go on the field trip.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means.So, the percentage of children that did not go to school:
The total number of students is 100.Students that went on the trip are 70.Students that did not go:
100 - 70 = 30 students30 students are % of 100:
30/100 × 100.30 × 10030%Therefore, using percentages we know that 30% of students did not go on the field trip.

Answers
Answer:
0.556 foot wide or 6 ²/₃ inches wide
Step-by-step explanation:
first we must calculate the total perimeter of the poster that will be decorated with the fabric:
the total perimeter of the poster = 4 + 4 + 5 + 5 = 18 feet long
you have 10 square feet of fabric, so its width should be 10 / 18 = 0.556 foot wide or 6 ²/₃ inches wide

a) The line goes through the grid point (4, 18), so its slope is ...
18/4 = 4.5 . . . . slope = "unit rate"
The units are (y-units)/(x-units) = bushels/hour.
