the food pantry distribution 10 oz bags of rice if 3 5 lb bags are donated to the pantry how many 10 ounce bags can be made

dolphi86 [110]

Answer:

24 bags can be made from three 5 pounds bags.

Step-by-step explanation:

Given that:

Three 5 pound bags are donated.

Total weight of bags = 3*5 = 15 pounds

We know that:

1 pound = 16 ounces

15 pounds = 16*15 = 240 ounces

A bag weighs 10 ounces.

Number of bags = $\frac{240}{10}$

Number of bags = 24 bags

Hence,

24 bags can be made from three 5 pounds bags.

The flight of a kicked football follows the quadratic function f(x)=−0.02x^2+2.2x+2, where f(x) is the vertical distance in feet

Sergio039 [100]

Answer:

110.9 feet

Step-by-step explanation:

The function that models the flight of the ball is

$f(x) = - 0.02 {x}^{2} + 2.2x + 2$ where f(x) is the vertical distance in feet and x is the horizontal distance the ball travels

If the ball hits the ground, then f(x)=0

$\implies - 0.02 {x}^{2} + 2.2x + 2 = 0$

The solution is given by the quadratic formula:

$x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a}$

We substitute a=-0.02, b=2.2, and c=2 to get:

$x = \frac{ - 2.2 \pm \sqrt{ {2.2}^{2} - 4 \times - 0.02 \times 2} }{2 \times - 0.02}$

This implies that:

$x = 110.90 \: or \: x = - 0.90$

Since we are dealing with time,

$x = 110.90$

To one decimal place, we have 110.9 feet
