For example, a bag of vigoro ultra turf fertilizer contains 29 pounds of nitrogen, 3 pounds of phosphoric acid, and 4 pounds of potash. another type of fertilizer, parker's premium starter, has 18 pounds of nitrogen, 25 pounds of phosphoric acid, and 6 pounds of potash per bag. determine the number of bags of each type required to yield a mixture containing 181 pounds of nitrogen, 65 pounds of phosphoric acid, and 32 pounds of potash.

When we are given information on different products and are asked to calculate a result from these, we are generally being provided with equations, in this case to calculate the number of bags required to make the requested mixture we have the following equations:

Where A and B represent the number of bosas of each fertilizer brand, as we have two unknowns we will use two equations like this:

One incognita is cleared depending on the other

The values obtained in the second are replaced

With the value of B it is replaced in the first one to obtain the value of A:

Answer

5 bags of Vigoro Ultra Turf and 2 of Parker's Premium Starter are needed

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
