If a figure is scaled up by some amount x(by multiplying), while still being the same shape, the surface area will scale up by x^2, and the volume will scale up by x^3.
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]
The slope-intercept form of the equation of a line that passes through point (-2, -13) is y = 5x - 3. What is the point-
slope form of the equation for this line?
O y- 13 = 5(%- 2)
O y + 13 = 5(x + 2)
O y- 2 = 5(x- 13)
O y + 2 = 5(x+ 13)
[tex]y = \stackrel{\stackrel{m}{\downarrow }}{5}x-3\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]
well, what's the equation of a line whose slope is 5 and passes through (-2 , -13) ?
[tex](\stackrel{x_1}{-2}~,~\stackrel{y_1}{-13})\qquad \qquad \stackrel{slope}{m}\implies 5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-13)}=\stackrel{m}{5}(x-\stackrel{x_1}{(-2)})\implies y+13=5(x+2)[/tex]

Find the unknown side
length. Round to the
nearest tenth. 9 in and 7 in
Please explain how to solve.
Answer:
The missing side length is 5.7
Step-by-step explanation:
Using the pythagoream theorem you can find the missing side length of a right triangle.
The formula is [tex]a^{2} + b^{2} = c^{2}[/tex] where a and b are the lengths of the triangle legs and c is the hypotenuse.
So yours would be:
[tex]7^{2} + x^{2} = 9^{2}[/tex]
Square the numbers:
[tex]49 + b^{2} = 81[/tex]
Isolate b:
[tex]b^{2} = 32[/tex]
Square root both sides:
[tex]b=\sqrt{32}[/tex]
Simplify:
[tex]\sqrt{32} = 5.7[/tex]
The set {3, x, 2, 1} has a range of 2. What is the value of x?
Answer:
x = 1 or x = 2 or x = 3Step-by-step explanation:
The range = 2 = (greatest number in the set) - (lowest number in the set)
→ If we took x < 1 then the range would be 3 - x > 3 - 1 then 3 - x > 2 which is impossible ,therefore x could not be less than 1
→ If we took x > 3 then the range would be x - 1 > 3 - 1 then x - 1 > 2 which is impossible ,therefore x could not be higher than 3
Conclusion:1 ≤ x ≤ 3
then
x = 1 or x = 2 or x = 3

Step-by-step explanation: Okay so sun's you are trying to increase the recipe by four times That means you need to do what the recipe calls for four times and times what the recipe calls for by four or how many times larger you want to make it. So first we would do 3/4 X 4 = 12/16 And then from there we need to simplify And for this I'm pretty for sure lol We are going to divide the top by three and then the bottom by four.

an ice chest contains 8 cans of coke, 3 cans of pepsi, and 2 cans of 7up. what is the probability of pulling out an 7up
The probability of pulling out an 7up from the ice chest that contains the different drinks is 2/13.
What is the probability?Probability determines the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of pulling out an 7up = number of 7ups / total number of drinks
2/(8 + 3 + 2)

[tex] \frac{34.5}{12.95} = \frac{118.5}{x} \\ cross \: multipy \\ 34.5x = 118.5 \times 12.95 \\ x = \frac{118.5 \times 12.95}{34.5} \\ x = 44.48[/tex]

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

The following table represents the annual sales of a bakery for the last 7 years since the grand opening
The table is a linear regression model, and the equation of the regression model is y = 0.24x + 0.77
The scatter plot that represents the tableSee attachment for the required scatter plot
The best model of the scatter plotFrom the attached scatter plot, we can see that the points are almost on a straight line
Hence, the best model that fits the scatter plot is a linear model
The equation of the regression modelUsing a graphing calculator, we have the following calculation summary:
Sum of x = 28Sum of y = 12.1Mean X = 4Mean Y = 1.7286Sum of squares (SSX) = 28Sum of products (SP) = 6.7b = SP/SSX = 6.7/28 = 0.23929a = MY - bMX = 1.73 - (0.24*4) = 0.77143The regression equation is represented as:
y = bx + a
So, we have:
y = 0.23929x + 0.77143
Approximate
y = 0.24x + 0.77
Hence, the equation of the regression model is y = 0.24x + 0.77

The value of x that satisfies the given equation is -9.
The correct option is (A).
What is an equation?A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the making of mathematics.
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:

If you roll an 8. 5-by-11-inch piece of paper into a cylinder by bringing the two longer sides together, you get a tall, thin cylinder. If you roll an 8. 5-by-11-inch piece of paper into a cylinder by bringing the two shorter sides together, you get a short, fat cylinder. Which of the two cylinders has the greater volume?
The cylinder which would have the greater volume is that in which the two shorter sides together, you get a short, fat cylinder.
Which cylinder has the greater volume between the two?It follows from the task content that the cylinder is made from the same paper dimensions.
On this note, it follows that when the shorter sides are joined, the longer side represents the height of the cylinder formed.
Consequently, the shorter cylinder has the greater volume.

A bag contains 9 tiles, one for each letter in the word HAPPINESS. You
choose a tile at random. What is the probability that you choose a tile with
the letter S? What is the probability that you choose a tile with a letter other
than P?
Answer:
shown below
Step-by-step explanation:
9 different possible tiles to choose, but there are duplicates of two types of tiles. Out of 9 tiles, two of them are S. Therefore, the probability you choose an S is 2/9 (however much percent that is).
You'd reverse the math for letters other than P:
Out of 9 tiles, two of them are P. 9 minus 2 is seven. Seven out of 9 characters are not the letter P. Therefore, the probability you choose any letter other than P is 7/9 (however much percent that is).

Answer And Step-by-step explanation:
1. b + 59 = 90
90 - 59 =b
⇒ b = 31
3. 29 + b = 90
90 - 29 = b
⇒ b = 61
5. 23 + b = 90
90 - 23 = b
⇒ b = 67
7. 32 + b = 90
90 - 32 = b
⇒ b = 58
18. 88 + b = 180
180 - 88 = 92
⇒ b = 92
20. 96 + b =180
180 - 96 = b
⇒ b = 84
22. 73 + b = 180
180 - 73 = b

24. 91 + b = 180
180 - 91 = b

Answer:
Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.
