How many atoms of H is in 300g H2O
Answer:
[tex]1.003*10^{25}[/tex]
Step-by-step explanation:
We'll be using Avogadro's number which defines the amount of atoms in a mole.
To find the mole amount, we use the atomic mass to find the molar mass because the atomic mass represents how many grams are in a single mole of any element
2 Hydrogen atoms have an atomic mass of 2.016 g
1 Oxygen atom has an atomic mass of 15.999 g
Adding these two numbers gives us H2O's molar mass, which is 18.015 g/mol (grams per mole).
Now we take the supplied mass of 300g and divide it by the mm (molar mass) to find the amount of moles we have. 300/18.015 = 16.653
We have 16.653 moles in 300g of H2O.
Now we have to multiply 16.653 by Avogadro's number, [tex]6.022 * 10^{23}[/tex]
This gives us: [tex]1.003*10^{25}[/tex]

Neil and his mom are volunteering at an emergency relief center. To help prepare in case of a flood, they pack emergency kits with food and water. Neil puts 3 water bottles into each kit they pack. In all, he packs 150 water bottles. Which equation can you use to find the number of emergency kits k Neil packs?
The number of emergency kits that Neil packed in total for the 150 bottles is gotten as; k = 50 kits.
How to create equations?We are told that Neil puts 3 water bottles into each emergency kit packed.
Now, let the number of emergency kits be k.
Thus;
3k = 150
Division property of equality, we have;
3k/3 = 150/3
k = 50
Thus, the number of emergency kits that Neil packed is gotten as k = 50 kits.

Earthquakes are measured by the Richter scale and demonstrated by the formula R = log(A) where A measures the amplitude of the earthquake wave and A, is the amplitude of the smallest detectable wave (or standard wave). An earthquake is measured with a wave amplitude 1800 times as great as a standard wave. What is the magnitude of this earthquake using the Richter scale? Round to the nearest tenth.
Answer:
3.22
Step-by-step explanation:
log(18×100)
log18+log100
1.22+2
3.22
The magnitude of this earthquake using the Richter scale is approximately 3.3 (rounded to the nearest tenth).
How to determine the magnitude of the earthquakeTo calculate the magnitude of the earthquake using the Richter scale, we can use the formula
R = log(A/A₀),
where
A is the amplitude of the earthquake wave, and
A₀ is the amplitude of the standard wave.
If the earthquake wave's amplitude is 1800 times as great as the smallest detectable wave, this means A/A₀ = 1800.
Therefore, the magnitude of the earthquake (R) would be:
R = log(1800)
Let's calculate it:
R ≈ log₁₀(1800) ≈ 3.255
So, if we round this to the nearest tenth, the earthquake's magnitude on the Richter scale would be approximately 3.3.

Step-by-step explanation:
write an approximate equation of the line of best fit, then predict the average temperature.
Answer:
[tex]\textsf{\sf(a)} \quad y=-\dfrac54x+\dfrac{205}{2}[/tex]
(b) $46.25
Step-by-step explanation:
When adding a line of best fit, ensure that the number of points above and below the line is about equal.
See attachment for line of best fit.
Part (a)From inspection of the graph, two points on the line are (10, 90) and (50, 40). Therefore,
[tex]\textsf{let}\:(x_1,y_1)=(10,90)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(50,40)[/tex]
Calculating the slope of the line:
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{40-90}{50-10}=-\dfrac54[/tex]
Using the point-slope form of linear equation: [tex]y-y_1=m(x-x_1)[/tex]
(where m is the slope and (x₁, y₁) is a point on the line)
[tex]\implies y-90=-\dfrac54(x-10)[/tex]
[tex]\implies y-90=-\dfrac54x+\dfrac{25}{2}[/tex]
[tex]\implies y=-\dfrac54x+\dfrac{205}{2}[/tex]
(where x is the average monthly temperature in °F and y is the monthly heating costs in dollars)
Part (b)Substitute x = 45 into the equation found in part (a):
[tex]\implies -\dfrac54(45)+\dfrac{205}{2}=46.25[/tex]
Therefore, the monthly heating cost for a month with an average temperature of 45 °F is approximately $46.25

Which is true for

B. A vertex is the end point of a single line segment.
C. A vertex is a point that describes the corner or
intersection of an angle.
Answer:
C.
Step-by-step explanation:
It is the corner or a point where line segments meet.
Hi!
Your answer is C.
The vertex is the point where two different rays meet, forming an angle.
It can also simply be the point where 2 straight lines simply meet.
Option A is NOT correct because a vertex is not angle, it is a part of an angle.
Option B is NOT correct because, if there's only one segment, we cannot form a vertex.

Which measurements are correct? round side lengths to the nearest hundredth. check all that apply. m∠a = 57° m∠b = 15° c ≈ 10.89 ft h ≈ 8.09 ft h ≈ 31.28 ft
The correct measurements of the surveyors movement from all the options are; m∠b = 15° and h ≈ 31.28 ft
What are the correct elevation measurements?
From the image attached, we see that;
A surveyor found the angle of elevation from the ground to the top from a point = 33°
Now, the surveyor moves 20 ft towards the building and the angle of elevation becomes 48°. This means that ∠A and 48° are supplementary to each other.
Thus;
∠A + 48° = 180°
∠A = 180 - 48
∠A = 132°
From sum of angles in a triangle;
∠B + 33° + 132° = 180°
∠B = 180 - 165°
∠B = 15°
Using sine rule, we know that;
sin 33/C = sin B/20
Thus;
sin 33/C = sin 15/20
Solving for C gives;
C = 42.22
From trigonometric ratios, h/c = sin 48
h = 42.22 sin 48
h = 31.28 ft

What are the solutions of the quadratic equation 0 = 4(x - 3)2 - 16?
O 2 and -2.5
O 2 and 2.5
О 1 and -5
0 1 and 5
Answer:
x = 5, x = 1
Step-by-step explanation:
The quadratic equation 0 = 4(x - 3)2 - 16.
Using binomial theorem, (a - b)2 = a2 - 2ab + b2 to expand (x - 3)2.
0 = 4(x2 - 6x + 9 ) - 16.
Using distributive property to multiply 4 by x2 - 6x + 9.
0 = 4x2 - 24x + 36 - 16.
Subtract 16 from 36 to get 20.
0 = 4x2 - 24x + 20.
4x2 - 24x + 20 = 0.
Divide both sides by 4.
x2 - 6x + 5 = 0.
To solve the equation, factor and rewrite as x2 + ax + bx + 5
a + b = -6, ab = 1(5) = 5.
a = -5, b = -1.
Rewriting x2 - 6x + 5 as
(x2 - 5x) + (-x + 5)
Factor x in the first and -1 in the second group.
x(x - 5) - (x - 5)
Factor out common term
(x - 5)(x - 1)
By solving the above, we get
x = 5, x = 1

As per the given data:
We are given an equation, and we have to find the value of x that satisfies the equation.
We can use the following rule of exponents to find the result of the given equation:
(i) [tex](a^m)^n = a^{m \times n}[/tex]
(ii) [tex]a^m = a^n[/tex] then m = n
For the given equation:
[tex]3^{4x} = 27^{x - 3}\\3^{4x} = 3^{3(x - 3)}\\3^{4x} = 3^{3x - 9}[/tex]
