is the only irrational number on the list. As a reminder, an <em>irrational number</em> is one which can't be written as a ratio of two integers.
With a little scratch work, we can show that can be written this way:
And , which can be written as a ratio like , or any other where the numerator is 3 times larger than the denominator.
A proof of the irrationality of is pretty involved and advanced, so you'll just have to take my word for it for now!
Let current price = x cents
prior price = x+44 cents
9 loaves at current price cost 7 at prior price, so
9x=7*(x+44)
expand and rearrange,
2x=7*44=308
x=154
So the current price is $1.54
Answer:
4
Step-by-step explanation:
Add 2/3 until the number is 3 or more than 3.
2 servings: 2/3 + 2/3 = 4/3
3 servings: 4/3 + 2/3 =6/3 = 2
4 servings: 2 + 2/3 = 2 and 2/3
5 servings: 2 and 2/3 + 2/3 = 2 and 4/3
4/3 is greater than 1, so 2 and 4/3 is more than 3. That means you can only make 4 servings with 3 cups of raisings.
Answer:
Option D. 18.75 cm3
Step-by-step explanation:
we know that
The Boyle's law (Ideal gas law) states that Where temperature remains constant, the pressure is inversely proportional to volume.
so
In this problem we have
P1=150 kPa
P2=200 kPa
V1=25 cm³
substitute and solve for V2
