Answer:

50%

Step-by-step explanation:theres only 2 sides on a coin

Answer: 50% , as likely as not .

Step-by-step explanation:

The probability of a 2 on the die is 1/6. The probability of a heads on the coin is 1/2. That means that (on average) half the time you roll a 2 you'll also get heads and the other half you'll get tails. What's half of 1/6?

The possibilities are:

1H 2H 3H 4H 5H 6H

1T 2T 3T 4T 5T 6T

So, it's 1/12 that you'll get a 2 and heads (on average).

Based on the elements and charges in Copper (II) Oxalate, CuC₂O₄(s), the solubility in pure water is 1.7 x 10⁻⁴ M.

The solubility equilibrium (Ksp) is 2.9 x 10⁻⁸ so the solubility can be found as:

Ksp = [Cu²⁺] [C₂O₄²⁻]

Solving gives:

2.9 x 10⁻⁸ = S x S

S² = 2.9 x 10⁻⁸

S = 1.7 x 10⁻⁴ M

Answer:

The answer is 13, 9 and (-1)

Step-by-step explanation:

For x = (-2)

h(x) = (-2x + 9)

h(-2) = [-2(-2) + 9]

h(-2) = (4 + 9)

h(-2) = 13

For x = 0

h(x) = (-2x + 9)

h(0) = [-2(0) + 9]

h(0) = (0 + 9)

h(0) = 9

For x = 5

h(x) = (-2x + 9)

h(5) = [-2(5) + 9]

h(5) = [(-10) + 9]

h(5) = (-1)

Thus, The answer is 13, 9 and (-1) when x = (-2), 0 and 5 respectively.

Hi Student!

In the problem statement we are given a number of 0.38 meters which it then tells us to write and solve an equation to convert that to centimeters.  The first step would be to write an equation that would perfectly incapsulate what we are trying to do.

[tex]x = meters\ *\ \frac{100\ centimeters}{1\ meter}[/tex]

This equation can now be used for any amount of meters where we can input the amount of meters that we have and that will cancel with the meters on the bottom while multiplying by 100 to which we then will receive our value of x in centimeters.  Let's solve the equation using 0.38 meters.

Input the values

Cancel the meters

Simplify the expression

Therefore, our final answer is that 0.38 meters can be converted to centimeters which would then get 38 cm as the result.

Since the straw is 6 inches long, the approximate length of the cylinder's radius is 3.32 in

To find the radius of the cylinder, we need to apply Pythagoras' theorem.

Pythagoras' theorem states that in any right-angled triangle, the square of the hypotenuse side equals the sum of the squares of the other two sides.

Mathematically, c² = a² + b² where

Now, since the 6 inch straw inclined at an angle forms a right angle with the radius,r and length of the cylinder, h.

Since the length of the straw is the hypotenuse side, L we have that

L² = h² + r²

Making r the radius of the cylinder subject of the formula, we have

r = √(L² - h²)

Given that

Substituting the values of the variables into the equation,we have

r = √(L² - h²)

r = √(6² - 5²)

r = √(36 - 25)

r = √11

r = 3.316 in

r ≅ 3.32 in

So, the approximate length of the cylinder's radius is 3.32 in

By definition of coterminal angles, the angle 2π/3 has two coterminal angles: θ' = 14π/3 and θ' = - 4π/3. The angle - 11π/7 has no coterminal angles.

Two angles are coterminal when their terminal ends have the same direction. By the fact that two consecutive coterminal angles have a difference of 2π, we find the following definition:

θ' = θ ± 2π · i, i ∈ [tex]\mathbb{N}_{O}[/tex]     (1)

Now we proceed to determine the coterminal angles for each case:

a) θ = 2π/3

θ' = 14π/3, θ' = - 4π/3

b) θ = - 11π/7

There are no coterminal angles.

By definition of coterminal angles, the angle 2π/3 has two coterminal angles: θ' = 14π/3 and θ' = - 4π/3. The angle - 11π/7 has no coterminal angles.

Hi Student!

Usually the first step that I take for any problem would be to gather any important information that would be needed in the problem.  However, for this problem, it is pretty straight forward because we just need to solve for the unknown which is x.

Add 3 to both sides

Divide 8 from both sides

For the first equation, we were able to solve for x and get that the solution for the unknown is 1.25

Subtract 5 from both sides

Divide both sides by 7

For the second equation, we are able to solve for x and get that the solution for the unknown is 19/7

Subtract 6 from both sides

Divide both sides by 4

For the final equation, we are able to solve for x and get that the solution for the unknown is -0.25

Answer:

1) [tex]x=\frac{5}{4}=1\frac{1}{4}[/tex]

2) [tex]x=\frac{19}{7}=2\frac{5}{7}[/tex]

3) [tex]x=-\frac{1}{4}[/tex]

Step-by-step explanation:

1) 8x - 3 = 7

1. Group all constants on the right side of the equation

[tex]8x-3=7[/tex]

Add 3 to both sides:

[tex]8x-3+3=7+3[/tex]

Simplify the arithmetic:

[tex]8x=7+3[/tex]

Simplify the arithmetic:

[tex]8x=10[/tex]

2. Isolate the x

[tex]8x=10[/tex]

Divide both sides by 8:

[tex]\frac{8x}{8}=\frac{10}{8}[/tex]

Simplify the fraction:

[tex]x=\frac{10}{8}[/tex]

Find the greatest common factor of the numerator and denominator:

[tex]x=\frac{5\cdot 2}{4\cdot 2}[/tex]

Factor out and cancel the greatest common factor:

[tex]x=\frac{5}{4}[/tex]

2) 5 + 7x = 24

1. Group all constants on the right side of the equation.

[tex]5+7x=24[/tex]

Subtract 5 from both sides:

[tex]5+7x-5=24-5[/tex]

Group like terms:

[tex]7x+5-5=24-5[/tex]

Simplify the arithmetic:

[tex]7x=24-5[/tex]

Simplify the arithmetic:

[tex]7x=19[/tex]

2. Isolate the x

[tex]7x=19[/tex]

Divide both sides by 7:

[tex]\frac{7x}{7}=\frac{19}{7}[/tex]

Simplify the fraction:

[tex]x=\frac{19}{7}[/tex]

3)  5 = 6 + 4x

1. Swap sides

[tex]5=6+4x[/tex]

Swap sides:

[tex]6+4x=5[/tex]

2. Group all constants on the right side of the equation

[tex]6+4x=5[/tex]

Subtract 6 from both sides:

[tex]6+4x-6=5-6[/tex]

Group like terms:

[tex]4x+6-6=5-6[/tex]

Simplify the arithmetic:

[tex]4x=5-6[/tex]

Simplify the arithmetic:

[tex]4x=-1[/tex]

3. Isolate the x

[tex]4x=-1[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4}=\frac{-1}{4}[/tex]

Simplify the fraction:

[tex]x=\frac{-1}{4}[/tex]

Why learn this:

Linear equations cannot tell you the future, but they can give you a good idea of what to expect so you can plan ahead. How long will it take you to fill your swimming pool? How much money will you earn during summer break? What are the quantities you need for your favorite recipe to make enough for all your friends?

Linear equations explain some of the relationships between what we know and what we want to know and can help us solve a wide range of problems we might encounter in our everyday lives.

---------------------

Terms and topics

The most common use of linear equations is to solve problems involving an unknown variable, generally (but not always) x, and a known constant.

Solving linear equations requires isolating the unknown variable on one side of the equation and simplifying the remainder. Anything done to one side of the equation must also be done to the other when simplifying.

An equation of:

[tex]ax+b=0[/tex]

A typical linear equation with one unknown is in which a and b are constants and x is the unknown variable. In this case, we would isolate x by removing b from both sides of the equation before solving for it. We'd then multiply both sides of the equation by a, yielding the following result:

[tex]x = -\frac{b}{a}[/tex]
