3.70 and 3.700 are some examples to get you started.
The answer is c. You find the price per ounce. 4.29/24 = .178 then 3.49/18= .193 then 6.39/39= .163 and 2.49/14 = .177. The cheapest is c. Hope this helps!!!
We know the bottom triangle is a 45, 45, 90 triangle, so the hypotenuse is √2 times the value of the legs:
(√2)(√2)
=√4
=2
Now, we can use this to solve for y. The top triangle is a 30, 60, 90 triangle. The side we found above is the side across from the 30 degree angle. The side opposite the 60 degree angle is √3 times the side across the 30 degree angle. Therefore, we can solve for y by multiplying 2 by √3
y=2√3
1.5 as a fraction is 1 1/2
