Alexeev081 [22]

Answer:

The ball will take 2.6 seconds to hit the ground again.

Step-by-step explanation:

Sam kicks a soccer ball from the ground. The height of the ball (in feet) can be modeled with the function, h(t) = −16t(t − 2.6), where t is the time in seconds after the ball is kicked.

So, the ball will be at ground when h = 0 = - 16t(t - 2.6)

⇒ t = 0 or t = 2.6.

Therefore, the ball will take 2.6 seconds to hit the ground again. (Answer)

The ratio of hydrogen to oxygen atoms in water molecules is 2 to 1. If the beaker of water contained 4.1 moles of oxygen atoms,

Ad libitum [116K]

Answer:

8.2

Step-by-step explanation:

We have been given that the ratio of hydrogen to oxygen atoms in water molecules is 2 to 1.

We can represent this information as: $\frac{\text{Hydrogen}}{\text{Oxygen}} =\frac{2}{1}$

Let x be amount of moles of hydrogen atoms in water beaker. The proportion of hydrogen and oxygen moles will be same in water beaker.

Upon substituting our values in above proportion we will get,

$\frac{2}{1} =\frac{x}{4.1}$

$x=2\times 4.1$

$x=8.2$

Therefore, the moles of hydrogen atoms in water beaker will be 8.2.

Conversions: 24,900 miles into meters (m) (1 inch =2.54cm)

Orlov [11]

For this, we will be using dimensional analysis as such:

$\frac{24900\ mi}{1}*\frac{5280\ ft}{1\ mi}*\frac{12\ in}{1\ ft}*\frac{2.54\ cm}{1\ in}*\frac{1\ m}{100\ cm}=\frac{4007266560}{100}=40072665.6\ m$

In short, 24,900 miles is 40,072,665.6 (40,072,666 if rounded to the whole meter) meters.
