7. Jena has a triangular garden with a perimeter that can be represented by 25r ^ 2 - 9r + 14 . The sum of two sides of the gard

galben [10]

Answer: $15r^2-21r+5$

Step-by-step explanation:

Given: Perimeter of triangular garden = $25r^2 - 9r + 14$

The sum of two sides of the garden = $10r^2 + 12r + 9$

Perimeter is the sum of all sides of a triangle.

Third side = Perimeter of triangular garden - sum of two sides of the garden

$=25r ^ 2 - 9r + 14-(10r ^ 2 + 12r + 9)\\\\=25r ^ 2 - 9r + 14-10r ^ 2 - 12r - 9\\\\=15r^2-21r+5$

The expression represent the third side = $15r^2-21r+5$ .

When the coffee is brewed according to directions, a pound of coffee beans yields 50 cups of coffee (4 cups = 1 qt). How many kg

Basile [38]

we know that

$1\ pound=0.453592\ kg$

in this problem

a pound of coffee beans yields $50$ cups of coffee

by proportion

Find the kg of coffee that are required to produce $100$ cups of coffee

$\frac{0.453592}{50}\frac{kg}{cups} =\frac{x}{100}\frac{kg}{cups}\\ \\50*x=100*.453592\\ \\x =0.453592*100/50\\ \\x=0.907184\ kg$

therefore

<u>the answer is</u>

$0.907184\ kg$
