Answer:
There would be 10 quarters and 23 dimes.
Step-by-step explanation:
There are generally two methods to solving this type of problem. (1) is guess and check, where you try different amounts of dimes and quarters in combinations of 33 coins until you reach an amount of $4.80. However, we can also solve the problem algebraically using two equations and two variables. In this case, 'd' = amount of dimes and 'q' = amount of quarters. We know that there are 33 total coins, or d + q = 33. We also know that the amount of the coins is $4.80, or .10d + .25q = 4.80. Solving the first equation for 'q', we get q = 33 - d. We can then substitute this expression for 'd' in the second equation to solve for d: .10d + .25(33 - d) = 4.80 or .10d + 8.25 - .25d = 4.80. Combining like terms and using inverse operations, first subtraction then division, we get d = 23. If there are 23 dimes, then there must be 10 quarters, for a total of 33 coins or $2.30 in dimes and $2.50 in quarters.

<h3>
Answer: 70 ft^2 ( choice D )</h3>
=========================================================
Work Shown:
- L = 8 ft = length
- W = 3 ft = width
- H = 1 ft = height
SA = surface area of the rectangular prism (aka block or box)
SA = 2*(LW + LH + WH)
SA = 2*(8*3 + 8*1 + 3*1)
SA = 2*(24 + 8 + 3)
SA = 2*(35)
SA = 70 square feet
This is the amount of wrapping paper you would need to cover all six sides of the box. This assumes that there are no gaps or overlaps.
hm, well I cant write a story FOR you, but I can give ya some ideas! I suggest going a more comedic route, something over dramatic to fit the fact you have to write a story about math symbols haha. maybe a forbidden love story between them. maybe personify the symbols in your writing, making them more human. or go full crazy and make them walking talking symbols. maybe they're doodles on a white board, making an epic adventure through the scribbles! dont over think creative prompts like this, just have fun and be creative! happy writing ♡
