Given <span>20 yards for $30.00, unit rate = $30 / 20 yards = $1.5 per yard

Given 40 yards for $45.00, unit rate = $45 / 40 yards = $1.13 per yard

Given 50 yards for $70.00, unit rate = $70 / 50 yards = $1.4 per yard

Given 65 yards for $85.00, unit rate = $85 / 65 yards = $1.31 per yard

The best deal is the cheapest rate which is 40 yard for $45.00

the vertex of this parabola is at 4,-3 when the x value is 5 the y value is -6 what's the coefficient of the squared expression
schepotkina [342]

Answer:

d) -3

Step-by-step explanation:

The equation of a parabola in vertex form is given as:

y = a(x - h)² + k. Where (h, k) is the vertex of the parabola.

Given that the vertex of the parabola is at (4,-3) i.e h = 4 and k = -3.

The equation of the parabola is given as:

y = a(x - 4)² + (-3)

y = a(x² - 8x + 16) - 3

y = ax² - 8ax + 16a - 3

Given that when x = 5, y = -6. i.e:

-6 = a(5)² - 8a(5) + 16a - 3

- 6 = 25a - 40a + 16a - 3

-6 + 3 = a

a = -3

Maria adopted for dogs altogether they ate 1 3/4 pound of food each day 1 pound is equal to 16 ounces how many ounces of food wi
olga55 [171]

Answer:

65 ounces

Step-by-step explanation:

Number of dogs = 4

Each day, they ate 13/4 pounds of food

1 pound = 16 ounces

If 4 dogs eat 13/4 pounds of food

1 dog will eat x pounds of food

1 dog will eat = (1 * 13/4) / 4 = 13 /16

1 dog will eat 13 / 16 pounds of food each day.

1 pound = 16 ounces

13 / 16 pounds = y ounces

y = (13/16 * 16) / 1

y = 13 ounces

Each dog eats 13 ounces of food daily.

In five days, each dog will eat 13 * 5 = 65 ounces of food.
