The nickles and dimes had a value of $5.75. if there were 70 coins in all, how many were nickles?

1 answer:

Murrr4er [49]3 years ago

5 0

Answer:

25

Step-by-step explanation:

If all 70 were nickels, the value would be $3.50 Since that is 2.25 less, that means it needs 45 more 5 cents. Therefore, you would replace 5 of the nickels with dimes. This means there are 25 nickels and 45 dimes.

If (m+n)^2=m^2+n^2, what is (3^m)^n?

svp [43]

Answer:

$(3^m)^n=1$

Step-by-step explanation:

$(m+n)^2=m^2+n^2\\m^2+2mn+n^2=m^2+n^2\\(m^2+n^2)-(m^2+n^2)+2mn=0\\2mn=0\\This\ equation\ has\ two\ solutions\ : m=0,n=0\\\\But\ either\ way\ will\ result\ in\ the\ same\ answer.\\If\ m=0\ then,\\(3^0)^n\\=1^n\\=1\\\\If\ n=0 \ then,\\(3^m)^0\\=1$

If a bookshelf is 28 1/8 inches long,how many 1 7/8 inch thick books will it hold?

kotegsom [21]

I believe the correct answer is 15, because 15/8 x 15/1= 225/8 and when you simplify that you get 28 with 1/8 left over.

Answer: 352496

Step-by-step explanation:

First, to find 20% of 440,620, you can multiply:

0.2 x 440,620 = 88,124

Then, to find the new weight of the ship, you can subtract the 20% that was just found (88,124) from the ship's original weight (440,620) to get:

440,620 - 88,124 = 352,496

Therefore, the ship's weight is now 352496.

I hope this helps!
