a deck of cards labeled 1 thru 10......probability of picking a 5 are 1/10 because there is 1 five card out of a deck of 10 cards.

number cube is rolled, probability of rolling an even number is 3/6 or 1/2....because u have 3 even numbers and ur number cube has 6 total numbers.

probability of both events happening are : 1/10 * 1/2 = 1/20 or 1:20 <==

The probability Megan chooses a card with a 5 and rolls an even number is 1 out of 20.

The probability of choosing a card with a 5 is 1 out of 10, since there is only one card numbered 5 out of the 10 cards in the deck.

To find the probability of both events happening, we multiply the individual probabilities together.

Therefore, the probability Megan chooses a card with a 5 and rolls an even number is 1 out of 20.

Answer:

They will cost $80.

Step-by-step explanation:

First, find the out how much 1 pen cost(unit rate).

To do that, divide 100 by 10.

100÷10= 10

So, each pen cost $10.

Now, multiply the cost of 1 pen times 8.

10×8= 80

This concludes that 8 of the same pens cost $80.

All you must do is multiply 4 by 1 and 1/4, so 5 total pounds.

Question is not proper, Proper question is given below.

Denzel is comparing websites for downloading music. One charges a $5 membership fee plus $0.50 per song. Another charges $1.00 per song, but has no membership fee. Write and solve an equation to find how many songs Denzel would have to buy to spend the same amount at both websites.

Answer:

Denzel would have to buy 10 songs to spend the same amount at both websites.

Step-by-step explanation:

Let the number of songs be 'x'.

Given:

One charges a $5 membership fee plus $0.50 per song.

So the total cost at one site will be membership cost plus charges per song multiplied by number of songs.

framing in equation form we get;

Total Cost at one site = [tex]5+0.5x[/tex]

Another website charges $1.00 per song, but has no membership fee.

So the total cost at Another site will be charges per song multiplied by number of songs.

framing in equation form we get;

Total Cost at Another site = [tex]1\times x=1x[/tex]

To find the number of songs that results in same cost we should equate the two expression and solve.

[tex]5+0.5x=x[/tex]

Combining like terms we get;

[tex]5 = x-0.5x\\\\5=0.5x[/tex]

Now Dividing both side by 0.5 we get;

[tex]\frac{0.5x}{0.5} = \frac{5}{0.5} \\\\x=10\ songs[/tex]

Hence Denzel would have to buy 10 songs to spend the same amount at both websites.

step 2

Find the equation of the line parallel to the given line

The equation of the line in point slope form is

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=5[/tex]

[tex]point\ (-1,2)[/tex]

substitute

[tex]y-2=5(x+1)[/tex]

step 3

Convert to slope intercept form

Isolate the variable y

Step-by-step explanation:

Domain of Functions

Given a function h(x), we call the domain of h, all the values x can take so h exists. It's commonly easier to find the values of x for which h does NOT exist and then exclude them from the general domain of the real numbers.

The question provides us with the following functions

[tex]\displaystyle f(x)=x^2-3x-18[/tex]

[tex]\displaystyle g(x)=x^2-36[/tex]

[tex]\displaystyle h(x)=\frac{x^2-3x-18}{x^2-36}[/tex]

We called h(x) to the newly created function f/g(x)

To investigate the possible points of nonexistence for h, we factor h(x)

[tex]\displaystyle h(x)=\frac{(x-6)(x+3)}{(x-6)(x+6)}[/tex]

We can clearly see the denominator has two zeros at

[tex]\displaystyle x=6,\ x=-6[/tex]

A rational function cannot exist where the denominator is zero, regardless of the possible simplification with the numerator, as in this case. For example, for x=6 the function gets the value 0/0 and it's not defined there. We cannot simplify the common factor because they are part of the original function.

So, the domain of h is

[tex]\displaystyle (-\infty,\ -6 )\bigcup (-6,\ 6)\bigcup (6,+\infty )[/tex]

Or equivalently

[tex]\displaystyle \mathbb{R}-\left \{ -6,\ 6 \right \}[/tex]

The domain of the function (f/g)(x), given f(x)=x^2-3x-18 and g(x)=x^2-36, is all real numbers except x = 6 and x = -6. This is because we can't have g(x) equals to zero in (f/g)(x). Hence the domain is (-∞, -6) U (-6, 6) U (6, ∞).

In Mathematics, when dealing with the domain of the function (f/g)(x) it is important to understand that the domain is the set of all possible x values that we can input into the function. For the function (f/g)(x), given f(x)=x^2-3x-18 and g(x)=x^2-36, the denominator g(x) cannot be zero as this would mean dividing by zero, which is undefined in Mathematics. So we need to find the values of x for which g(x) ≠ 0. To do this, we set g(x) equal to zero and solve for x. So, x^2-36=0. Simplifying this, we get (x+6)(x-6) = 0. Hence the roots of the equation are  x = 6, x = -6.

These are the values for which g(x) will become zero. Since we can't have g(x)=0 in (f/g)(x), the domain of the function (f/g)(x) is all real numbers except x = 6, x = -6. So, the domain of (f/g)(x) is (-∞, -6) U (-6, 6) U (6, ∞).

3 x 1/10 is 0.3 because it represents one tenth of 3, while 3 x 10 is 30 as it increases the value of 3 tenfold. Powers of ten and negative exponents demonstrate that each step in exponent changes the scale of the number by a factor of ten.

The reason why 3 x 1/10 is less than 3 x 10 is due to the values being multiplied by 3. When multiplying 3 by 1/10, you are essentially taking one tenth of 3, which gives you 0.3. However, when multiplying 3 by 10, you are increasing 3 tenfold, which results in 30.

To understand the scale, considering that each positive power of 10 is ten times bigger than the previous one, for instance from 3.2 to 3.2 x 10, and each negative power is ten times smaller, like from 3.2 to 3.2 x 1/10 . Powers of ten and their associated exponents allow us to easily compare and calculate with vastly different magnitudes, and this concept underlies the multiplication comparisons posed in the initial question.

Answer:

140 degrees

Step-by-step explanation:

Due to ∠3 and ∠4 being vertical angles (they are across from one another) their measures are the same, therefore:

⇒ m∠3=m∠4

and since their measures are given in terms of x to find x just substitute:

⇒ x+30=2x-80 ⇒ x=110

We substitute x in m∠3=x+30 and find that m∠3=140 degrees

Final answer:

The perimeter of the square playground can be found by adding the lengths of all four sides. Two equivalent expressions for the perimeter are 8n + 8 and 4(2n + 2).

Explanation:

To find the perimeter of the playground, we need to add up the lengths of all four sides. Since the playground is a square, all four sides are equal in length.

The length of each side of the playground can be found by subtracting twice the width of the sidewalk from the overall length of the sidewalk. This is because the sidewalk wraps around the playground on all sides.

So, the length of each side of the playground is (2n+3) - 2(0.5) = 2n + 2.

The perimeter of the playground is then 4 times the length of each side, which is 4(2n + 2) = 8n + 8 yards.

Two equivalent expressions for the perimeter of the playground are 8n + 8 and 4(2n + 2).

Step-by-step explanation:

For both times , the probability of getting blue is the same.

Probability = [tex]\frac{number of favorable cases}{total number of cases}[/tex]

The number of favorable cases for blue = 4

Total number of cases = 9

CPCTC is an acronym for Corresponding Parts of Congruent Triangles are Congruent.

If ΔRST ≅ ΔXYZ then

∠R = ∠X

∠S = ∠Y

∠T = ∠Z

RS  = XY

ST  = YZ

RT  = XZ

To prove ΔRST ≅ ΔXYZ, perform a sequence of transformations and apply CPCTC to identify congruent parts.

To prove that ΔRST ≅ ΔXYZ, we need to perform a sequence of transformations that move ΔRST onto ΔXYZ. Once the triangles are superimposed, we can use the Corresponding Parts of Congruent Triangles are Congruent (CPCTC) to identify congruent parts.

CPCTC states that if two triangles are congruent, then their corresponding parts (sides and angles) are also congruent. In this case, the parts of ΔRST that are congruent to the corresponding parts of ΔXYZ are:
