Answer:
Because it had more cents
Step-by-step explanation:
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.
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.

Answer:
adjacent and complementary angles
Step-by-step explanation:
we know that
If the sum of two angles is equal to then, the angles are Complementary
and
Two angles are Adjacent when they have a common side and a common vertex
In this problem we have
-----> by complementary angles
and
m<1 and m<4 have a common side and a common vertex
therefore
m<1 and m<4 are adjacent and complementary angles
b. buying a membership for $35 and then getting the item at a 15% discount
c. buying the item online at a 10% discount and paying $4 extra for shipping
Answer:
Buying the item online at a 10% discount and paying $4 extra for shipping
Step-by-step explanation:
Ray wants to buy an item worth 500$ in the most cost-effective way. Let's study each of the 3 cases and see with option is the best.
In the first option, he'll buy the item at list price with a coupon for $10 off. So he'll buy it at 500-10 =$490.
In the second option, he'll buy a membership for $35 and then get the item at a 15% discount. With a 15% discount, the price of the item will be 500 - (500*0.15) = 500 - 75 = $425. And with the membership price, he'll pay a total of 425 + 35 = $460.
The third option is to buy the item online at a 10% discount and pay $4 for the shipping. At 10% discount, the price of the item will be 500 - (500*0.1) = 500 - 50 = $450. And with cost of the shipping, he'll pay a total of 450+4 = $454.
So if he chooses the first option, he'll pay $490. With the second, he'll pay $460. And finally with the third, he'll pay $454.
So the third option is the most cost-effective, buying the item at $454.
Hope this helps! :)
