arlik [135]

Answer:

4 pounds of of Vigoro Ultra Turf fertilizer and 1 pound of Parkera's Premium Starter will yield the required mixture.

Step-by-step explanation:

In bag of Vigoro Ultra Turf fertilizer:

29 pounds of nitrogen, 3 pounds of phosphoric acid, and 4 pounds of potash

In bag of Parkera's Premium Starter:

18 pounds of nitrogen, 25 pounds of phosphoric acid, and 6 pounds of potash

Let the mass of Vigoro Ultra Turf fertilizer = x

Amount of nitrogen in x amount = 29 x

Amount of phosphoric acid in x amount = 3x

Let the mass of Parkera's Premium Starter= y

Amount of nitrogen in y amount = 18 y

Amount of phosphoric acid in y amount = 25 y

Amount of nitrogen in desired mixture formed by combing x and y fertilizers bag : 134 pounds

29 x + 18 y = 134 ..[1]

Amount of phosphoric acid in desired mixture formed by combing x and y fertilizers bag : 37 pounds

3x + 25 y = 37 ..[2]

Solving [1] anf [2] by substitution method :

$x=\frac{134-18y}{29}$

$3\times \frac{134-18y}{29}+25y=37$

y = 1

$x=\frac{134-18y}{29}=4$

4 pounds of of Vigoro Ultra Turf fertilizer and 1 pound of Parkera's Premium Starter will yield the required mixture.

{3x+y=-3 write your response below with work {x=-y+3 x= y=

dalvyx [7]

Answer:

x = -3

y = 6

Step-by-step explanation:

3x + y = -3

x = -y + 3

3x + y = -3

3(-y + 3) + y = -3

-3y + 9 + y = -3

-3y + y + 9 = -3

-2y + 9 = -3

-2y = -3 - 9

-2y = -12

y = -12/-2

y = 6

x = -y + 3

x = -6 + 3

x = -3

The distance between ladder and bottom of the slide is 4.9 meters.

Step-by-step explanation:

Given,

Height of ladder = 1 m

Length of slide = 5 m

The ladder will serve as perpendicular and slide will serve as hypotenuse.

The distance from bottom of the slide to ladder will be base.

a = 1

c = 5

$a^2+b^2=c^2\\(1)^2+b^2=(5)^2\\1+b^2=25\\b^2=25-1\\b^2=24$

Taking square root on both sides

$\sqrt{b^2}=\sqrt{24}\\b=4.89$

Rounding to the nearest tenth

b = 4.9 meters

The distance between ladder and bottom of the slide is 4.9 meters.

A pumpkin patch charges $5 for large pumpkins and $3 for small

Kamila [148]

Answer:

Step-by-step explanation:

Pumpkins are good for more than just jack-o’-lanterns: you can decorate with them, carve them, eat them, or plant the seeds so you have free pumpkins next year. You can find pumpkins for sale at farmers markets, pumpkin patches, and national chain retailers like Costco, Kroger, and Walmart. Farmers markets and pumpkin patches tend to price their pumpkins by the pound, charging around $16 to $25 for large pumpkins. Chain stores charge a per-pumpkin price, which is usually around $3 for small, decorative pumpkins and $5 to $10 for carving pumpkins. Below, we list the various uses for pumpkins, the places that sell pumpkins, and the average pumpkin prices.
