1/4x^2=27/4

Answers

Answer 1

Answer: Multiple both sides by 4 and it will cancel out the 4 on the 27/4 and the 4 in the 1/4 leaving 1x^2=27 then you square root both sides and your final answer will be x=-3 square root 3 AND x=3 square root 3

a bank contains 27 coins consisting of dimes and quarters. the coins have a total value of $4.95. Find the number of dimes and quarters in the bank.

Answers

12 dimes and 15 quarters
12 quarters and 10 dimes to make 4 dollars and
3 quarters and 2 dimes to make 95 cents

Final answer:

The bank has 15 quarters and 12 dimes.

Explanation:

This problem can be solved using systems of equations. Let's define the variables: let D represent the number of dimes and Q represent the number of quarters.

From the problem, we have two equations:

D + Q = 27 (the total number of coins)
0.10D + 0.25Q = 4.95 (the total value of the coins)

Multiply the first equation by 0.10 to make the coefficients of D the same in both equations:

0.10D + 0.10Q = 2.70

Subtract this from the second equation to find Q:

0.15Q = 2.25. Consequently, Q = 15 quarters.

Substitute Q = 15 into the first equation to find D:

D + 15 = 27, hence D = 12 dimes.

Any number between 8.434 and 9.283 will do the job.

The only whole number that can do it is 9 .

8 cubed = 512 too small
9 cubed = 729 just right
10 cubed = 1,000 too big
