a quarter weighs approximately 5.7 grams and a dime weighs approximately 2.3 grams. A bag with 57 quarters and some dimes weighs 366.3 grams. How many dimes are there in the bag?

Answers

Answer 1
Answer: Answer: 95 dimes



Step by step explanation
Answer 2
Answer:

Final answer:

The problem is solved by first calculating the total weight of the quarters and subtracting this from the total weight to find the weight of the dimes. Dividing this weight by the weight of a single dime, we find that there are 18 dimes.

Explanation:

This is a Mathematics problem that can be solved using simple algebra. To solve, let's set up an equation based on the information given. The weight of the quarters and dimes together equals 366.3 grams.

We know that 57 quarters each weighs 5.7 grams for a total weight of 57 * 5.7 = 324.9 grams. So, we subtract this from the total weight to find the weight of the dimes.

366.3 - 324.9 = 41.4 grams. So, the dimes combined weigh 41.4 grams.

Since each dime weighs around 2.3 grams, we can find the number of dimes by dividing the total weight of the dimes by the weight of a single dime: 41.4 / 2.3 = 18.

So, the bag contains 18 dimes.

Answers

D. 7x2+3y2+4x+4x2−4y+2 is your correct answer

-3x² + 3y² + 4x  + 4x² - 4y + 2

Add like terms.

x² + 3y² + 4x - 4y + 2

So the answer is D.

-734.8--1.67 with work? What is the work for this

Answers

Answer:

-733.13

Step-by-step explanation:

Take absolute value of each number

(add absolute value bars to show what you're doing)

-734.8 = 734.8

-1.67 = 1.67

Then do regular subtraction

734.8 - 1.67 = 733.13

Then put back the negative symbol in front and you have your answer

-733.13
