Answer:
Because it had more cents
Step-by-step explanation:
Final answer:
The question is an example involving principles of physics, specifically force, mass and motion. The quarter didn't roll down the hill with the nickel because it is heavier and requires more force to overcome static friction. Factors such as coin's mass, hill's slope, and gravity play a role in determining whether an object will roll down a slope.
Explanation:
Whether a quarter or a nickel would roll down the hill depends on a combination of the coin's mass and the slope of the hill. Because a quarter is heavier than a nickel, it requires more force to overcome static friction to start its roll than a nickel would. So if the hill is not steep enough, the quarter, due to its larger mass, might not roll whereas the nickel might.
Here, it might also be worth considering the shape and the 'coin dropped inside an airplane' scenario mentioned in the reference info. If we think of this in terms of the airplane, just like an observer on an airplane sees a coin drop straight down (as the coin is moving with the airplane), the quarter and nickel on the hill would also be moving with the earth's rotation. However, this effect is negligibly small and not relative to the situation of one rolling and the other not.

Step-by-step explanation:
x = pens and y = pencils
4x + 5y = 6.71....multiply by 5
5x + 3y = 7.12....multiply by -4
--------------------
20x + 25y = 33.55 (result of multiplying by 5)
-20x - 12y = - 28.48 (result of multiplying by -4)
--------------------add
13y = 5.07
y = 5.07 / 13
y = 0.39 <=== cost of a pencil
4x + 5y = 6.71
4x + 5(0.39) = 6.71
4x + 1.95 = 6.71
4x = 6.71 - 1.95
4x = 4.76
x = 4.76/4
x = 1.19 <==== cost of a pen

Answer:
Kelly is wrong and the recipe will make 19 cups of punch.
Step-by-step explanation:
We are given that,
The amount of ingredients in the recipe of punch after converting the units to 'cups' are given by,
Pineapple juice = 3 pints = 6 cups .......................(As 1 pint ≈ 2 cups)
Orange juice = 5 cups
Lemonade = gallon = 4 cups ...........................(As 1 gallon = 16 cups)
Apricot nectar = 1 quart = 4 cups .........................(As 1 quart = 4 cups)
Then, the total cups of punch = 6 + 5 + 4 + 4 = 19 cups.
Thus, Kelly is wrong and the recipe will make 19 cups of punch.

1/3 of 12= 4 while
1/4 of 12 = 3
to check your work you would get a calculator (if possible) and divide 3by 12 or 4 by 12 then if you get .33 (divide 3 by 12 like 3/12) its 1/3. if its .25 (divide 4 by 12 like 4/12) its 1/4
1/4 of 12 = 1/4 * 12 or .25 * 12 = 3
1/3 of 12 = 1/3 * 12 or .33"" * 12 = 4
3>4
