Answer:
The greatest amount of fizzy drink he can make is 420 ml
Step-by-step explanation:
we know that
The ratio of the parts of orange juice to parts of lemonade is
so
using proportion
Find out the milliliters of lemonade needed to make fizzy drink with 300 ml of orange juice
Let
x -----> milliliters of lemonade needed
<em>Find the greatest amount of fizzy drink he can make</em>
Adds the milliliters of lemonade plus the milliliters of orange juice
therefore
The greatest amount of fizzy drink he can make is 420 ml
The answer is 18, six sides and each side is 3 feet so:
6 x 3 = 18
See image for naming of the sides: the medians are
ab, bc, and ac; and sides are a, b, and c
Pick one median, say, ab. The following are true:
ab < a
ab < b
->
ab + ab < a + b
ab < 0.5*(a+b) | add 0.5*c to the right hand side (does not change inequality)
ab < 0.5(a+b+c) = half perimeter
so ab < half perimeter
Same argument for bc, and ac holds.
