Answer:

Sarah is watching a video online that is 4.7 minutes long.

Step-by-step explanation:

As we know 60 sec = 1 minute

⇒60×4 sec = 1×4 minutes

⇒240 sec = 4 minutes

⇒246.987 ≈ 247

                  = 240 + 7 seconds

                  = 4 minutes 7 seconds

                  = 4.7 minutes

∴ we get

Step-by-step explanation:

The amount of water released will be 1.081 grams.

The balanced chemical equation for the reaction between hydrogen gas and oxygen gas to form water is:

2H₂+ O₂ -> 2H₂O

According to the equation, 2 moles of hydrogen gas react with 1 mole of oxygen gas to form 2 moles of water. This means that the mole ratio of oxygen gas to water is 1:2.

If 30.0 moles of oxygen gas are used, we can use this mole ratio to calculate the number of moles of water that will form:

30.0 moles O₂ x (2 moles H2O / 1 mole O₂) = 60.0 moles H₂O

So, 60.0 moles of water will form.

To convert from moles to grams, we need to use the molar mass of water, which is approximately 18.015 g/mol. Therefore:

60.0 moles H₂O x 18.015 g/mol = 1,081 g

So, 1,081 grams of water will form.

[tex]\stackrel{\large{\frown}}{ADC} = 186^{\circ}[/tex]

Step-by-step explanation:

Given

See attachment

Required

Determine the measure of [tex]\stackrel{\large{\frown}}{ADC}[/tex]

[tex]The\ sum\ of\ angles\ in\ a\ circle\ is[/tex] [tex]360^{\circ}[/tex].

So, we have:

[tex]\stackrel{\large{\frown}}{ADC} + \stackrel{\large{\frown}}{APB} + \stackrel{\large{\frown}}{BPC} = 360^{\circ}[/tex]

Where:

[tex]\stackrel{\large{\frown}}{APB} = 70^{\circ}[/tex]

[tex]\stackrel{\large{\frown}}{BPC} = 104^{\circ}[/tex]

Substitute these values in the above equation.

[tex]\stackrel{\large{\frown}}{ADC} + 70^{\circ} +104^{\circ} = 360^{\circ}[/tex]

[tex]\stackrel{\large{\frown}}{ADC} + 174^{\circ} = 360^{\circ}[/tex]

Collect Like Terms:

[tex]\stackrel{\large{\frown}}{ADC} = 360^{\circ} - 174^{\circ}[/tex]

[tex]\stackrel{\large{\frown}}{ADC} = 186^{\circ}[/tex]

Answer:

The population of Hawks and other species would likely start to edge off.

Step-by-step explanation:

Commonly, a Food Chain is dependent on all the parts of it sataying at a perfect point. If the food that the Snakes eat starts to run out, more of them will die off. With less Snakes, the Hawks will then have less food, and that continues throughout the chain. The same thing would happen if there was too much food, except instead of the populations of species dying off, the Snake population would spike.

Answer:

You can also work on the ways that you write polynomials. One way to write a polynomial is in standard form. In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to right.

Step-by-step explanation:

Write the expression 3x−8+4x5 in standard form.

First, look at the degrees for each term in the expression.

3x has a degree of 1

8 has a degree of 0

4x5 has a degree of 5

Next, write this trinomial in order by degree, highest to lowest

4x5+3x−8

The answer is 4x5+3x−8.

The degree of a polynomial is the same as the degree of the highest term, so this expression is called a fifth degree trinomial.

Answer: b = 14.

Step-by-step explanation:

We have the function:

f(x) = x^2 + b*x - 21

The minimum of a quadratic function will be at the vertex, and the vertex is at the value of x such that:

f'(x) = 2*x + b = 0

then the vertex is at:

x = -b/2

Then the minimum of the function f(x) will be:

f(-b/2) = (-b/2)^2 + b*(-b/2) - 21

and we know that the minimum value is -70, then:

f(-b/2) = -70 = (b^2)/4 - (b^2)/2 - 21

Now we need to solve this equation for b.

-70 = (b^2)/4 - (b^2)/2 - 21

-70 = -(b^2)/4 - 21

-70 + 21 = -(b^2)/4

49 = (b^2)/4

49*4 = b^2

196 = b^2

√196 = b = 14

The value of b is 14.

Answer:

The height of her friend is 4.826 feet.

Step-by-step explanation:

The length of the shadow ([tex]x_{S}[/tex]), measured in feet, is directly proportional to the height of the person ([tex]x_{P}[/tex]), measured in feet. That is:

[tex]x_{P} \propto x_{S}[/tex]

[tex]x_{P} = k\cdot x_{S}[/tex] (1)

Where [tex]k[/tex] is the proportionality constant, no unit.

We can eliminate this constant by constructing this relationship:

[tex]\frac{x_{P,M}}{x_{S,M}} = \frac{x_{P,F}}{x_{S,F}}[/tex] (2)

Where M and F represents Melody and Melody's friend. If we know that [tex]x_{P,M} = 5\,ft[/tex], [tex]x_{S,M} = 7\,ft[/tex] and [tex]x_{S,F} = 6\,ft[/tex], then the height of his friend is:

[tex]x_{P,F} = \left(\frac{x_{P,M}}{x_{S,M}} \right)\cdot x_{S,F}[/tex]

[tex]x_{P,F} = \left(\frac{5\,ft}{7\,ft}\right)\cdot (6\,ft)[/tex]

[tex]x_{P,F} = 4.286\,ft[/tex]

The height of her friend is 4.826 feet.

Answer:

19 minutes

Step-by-step explanation:

Taking the sea level as the reference point, the values of depths to be considered can be determined as follows;

Total depth from sea level to the sea floor = 104 feet

Katy's depth from the sea level (depth covered) = 28 feet

Katy's distance to the sea floor = 104 - 28

                                          = 76 feet

Katy's distance to the sea floor = 76 feet

But Katy moves at a rate/ speed of 4 feet per minute;

So that,

speed = [tex]\frac{distance}{time}[/tex]

time = [tex]\frac{distance }{speed}[/tex]

       = [tex]\frac{76}{4}[/tex]

       = 19

time = 19 minutes

Therefore it would take Katy 19 minutes to reach the sea floor.

Answer:

Step-by-step explanation:

No, Colin is not correct. He needs to subtract first to get the total distance and then divide by the rate. He should have put parentheses around 104–28 and then divided by 4 to get the answer of 19 minutes.
