Answer: Equivalent ratios are 8 : 24 and 3 : 9
Explanation: 24 divided 8 equals 3, so 3 times 3 equals 9.
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
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>
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
