A coffee distributor needs to mix a(n) Organic Free Trade coffee blend that normally sells for $9.40 per pound with a Gualtemala Antigua coffee blend that normally sells for $12.90 per pound to create 50 pounds of a coffee that can sell for $12.34 per pound. How many pounds of each kind of coffee should they mix? A) Write an equation using the information as it is given above that can be solved to answer the question. Use
x
as your variable to represent the quantity of Organic Free Trade coffee blend.
Equation:

B) They must mix
pounds of the Organic Free Trade Blend
pounds of the Gualtemala Antigua Blend.
Round your answers to the nearest whole number of pounds.

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
