Ted has $3.90. He has only dimes and quarters. He has 27 coins altogether. How many of each does he have
mestny [16]

Answer: 8 quarters 19 dimes

Step-by-step explanation:

we already know 8+19=27, if 4 quarters equals a dollar then you use 4 quarters each to create 2 dollars.

then, use 10 dimes to create another dollar summing it up to $3. now all we have to do is make 90 cents, and we've already used 18 coins.

if we used another 9 dimes, that would equal 90 cents.

in conclusion, 4+4= 8

8+10= 18

18+9= 27, and having $3.90

The Snack Shack is making a batch of trail mix. They use 9 1/3 pounds of granola, 9 1/3 pounds of nuts, and 9 1/3 pounds of yogu
Leokris [45]

What goes into the bowl . . .

-- granola . . . 9-1/3 pounds
-- nuts . . . . . 9-1/3 pounds
-- raisins. . . . 9-1/3 pounds

How much is in the bowl all together ?

     (9-1/3) + (9-1/3) + (9-1/3) = 27-3/3 = <em>28 pounds</em> .

After stirring, mixing, shaking, and resting, how much is
still in the bowl ?

       Still 28 pounds.  Nothing else went in, and nothing came out.

After a month, nobody has come into the store yet asking to buy
28 pounds of trail mix. So before it spoils or gets soggy, they decide
to split it up into 14 smaller packages, and see if more people will
buy smaller packages.

They make all of the small packages exactly equal.
How much trail mix is in each one ?

       (28 pounds)  divided by  (14 packages) =  <em>2 pounds/package</em>

A rectangular street sign has an area of 40 square inches and a perimeter of 28 inches. What are the dimensions of the sign?
Usimov [2.4K]

Answer: 4 inches by 10 inches

Step-by-step explanation:

The area of a rectangle can be written as b*h, while perimeter is equal to (2b +2h).

A = b*h = 40

P = 2b + 2h = 28

P = 2b + 2h

28 = 2b + 2h

28 = 2(b+h)

14 = b + h

What two numbers add to 14 and multiply to 40?

4 * 10 = 40

4 + 10 = 14
