Anita is filling a small pool for her kids. Currently, there are 60 gallons of water in the pool and she is filling the pool at a rate of 50 gallons every 5 minutes. The pool holds 200 gallons of water.

Which equation represents the amount of minutes ( m) that it will take to fill the pool?

Answer:

238°

Step-by-step explanation:

In a cyclic quadrilateral, the pair of opposite angles add up to 180 degrees.

So, the angle "21x - 2" and the angle "38x + 5"  add up to 180.

So, we can write an equation and solve for x first:

[tex]21x-2+38x+5=180\\59x+3=180\\59x=180-3\\59x=177\\x=3[/tex]

x = 3

Now, Arc FGH is DOUBLE of Angle A. Angle A is "38x + 5". We know x, so angle A is:

Angle A = 38x + 5 = 38(3) + 5 = 119

Thus, Arc FGH = 2 * 119 = 238°

Answer:

Probability of getting blue both times = [tex]\frac{16}{81}[/tex]

Step-by-step explanation:

A fair spinner has 9 equal sections: 3 red, 4 blue and 2 green.  

It is spun twice.  

We have to find the probability of getting blue both times?.

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

Hence the probability = [tex]\frac{4}{9}[/tex]

We have to get it two times so final probability = [tex]\frac{4}{9}\times \frac{4}{9} = \frac{16}{81}[/tex]

Answer:

(-9, 3)

Step-by-step explanation:

To rotate a point 270°:

R₂₇₀ (x, y) = (y, -x)

So the answer would be (-9, 3).

Firstly they are not numbers, they are ordered pairs or points with a form [tex](x,f(x))[/tex] yes they probably lie on a function graph but that would be rather impossible to find out. The function may be linear, exponential, logarithmic etc. we can't tell. All we can tell is that if these ordered pairs [tex]P_{1,2,3}[/tex] lie on a function graph [tex]P_{1,2,3}\in G_f[/tex] where [tex]G_f=\{(x,f(x)):\forall x\in D_f\wedge f(x)\in T_f\}[/tex] where D is definition set of function defined x's and T a transformation set of f(x)'s for this function. So yes they may lie on some lambda function but they themselves are nothing but an ordered pairs with no meaningful connection.

Hope this helps.

Answer:

no

Step-by-step explanation:

there are two coordinates with the same x value

Step-by-step explanation:

making x subject in eq 1

x= (-1-9y)/-14

substituting the value of x in eq 2

17(-1-9y/-14)=7+9y

(-17-153y)/-14=7+9y

-17-153y=-98-126y

-17+98=153y-126y

81=27y

y=3

substituting this value of y in eq 1

-14x=-1-9(3)

-14x=-28

x=2

Answer:

[tex]\frac{61}{90}[/tex]

Step-by-step explanation:

We require to create 2 equations with the repeated value 7 after the decimal point

Let x = 0.6777777... ← multiply both sides by 10 and 100

10x = 6.777...... → (1)

100x = 67.777..... → (2)

Subtract (1) from (2) thus eliminating the repeating value

90x = 61 ( divide both sides by 60 )

x = [tex]\frac{61}{90}[/tex]

The decimal 0.67 with the repeating 7 can be written as the simplified fraction 2/3.

To rewrite the decimal 0.67 with the repeating 7 as a simplified fraction, we can use the concept of infinite geometric series.

Let x = 0.677777...

Multiply both sides of the equation by 10 to shift the decimal point:

10x = 6.777777...

Now, subtract the original equation from the shifted equation to eliminate the repeating 7s:

10x - x = 6.777777... - 0.677777...

Simplifying, we get:

9x = 6

Divide both sides of the equation by 9 to solve for x:

x = 6/9

The fraction 6/9 can be further simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3:

x = (6/3) / (9/3)

x = 2/3

Therefore, the decimal 0.67 with the repeating 7 can be written as the simplified fraction 2/3.

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

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, ∞).

It takes 10.155 years until you have $3,000 ⇒ 3rd

Step-by-step explanation:

The formula for compound interest, including principal sum is:

[tex]A=P(1+\frac{r}{n})^{nt}[/tex] , where

∵ You decide to put $2,000 in a savings account

∴ P = 2000

∵ You want to save for $3,000

∴ A = 3000

∵ The account has an interest rate of 4% per year and is

   compounded monthly

∴ r = 4% = 4 ÷ 100 = 0.04

∴ n = 12 ⇒ compounded monthly

- Substitute all of these values in the formula above to find t

∵ [tex]3000=2000(1+\frac{0.04}{12})^{12t}[/tex]

- Divide both sides by 2000

∴ [tex]1.5=(1+\frac{1}{300})^{12t}[/tex]

∴ [tex]1.5=(1\frac{1}{300})^{12t}[/tex]

- Change the mixed number to an improper fraction

∴ [tex](1.5)=(\frac{301}{300})^{12t}[/tex]

- Insert ㏒ for both sides

∴ [tex]log(1.5)=log(\frac{301}{300})^{12t}[/tex]

- Remember [tex]log(a)^{n}=nlog(a)[/tex]

∴ [tex]log(1.5)=(12t)log(\frac{301}{300})[/tex]

- Divide both sides by [tex]log(\frac{301}{300})[/tex]

∴ 121.84 = 12 t

- Divide both sides by 12

∴ 10.155 = t

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

The average annual income, I, in dollars, of a lawyer with an age of x years is modeled with with the following function:

I = - 425x² + 45500x - 650000 .......... (1)

If the average annual income of the lawyer at the age of x years is $250000, then from the equation (1) we can write

- 425x² + 45500x - 650000 = 250000

⇒ - 425x² + 45500x - 900000 = 0

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:

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.

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.
