Which of these is the best deal? [Note: there are two pints in a quart, and four quarts in a gallon]

Question 6 options:

A)

one quart of milk for $1


B)

1 gallon of milk for $2


C)

two quarts of milk for $1.50


D)

One pint of milk for 50 cents

For this case we must indicate an expression equivalent to:

[tex]x ^ {- \frac {5} {3}}[/tex]

By definition of power properties we have to:

[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]

Then, we can rewrite the expression as:

[tex]\frac {1} {x ^ {\frac {5} {3}}}[/tex]

We also have that by definition of properties of powers it is fulfilled that:

[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

Then, the expression is like:

[tex]\frac {1} {\sqrt [3] {x ^ 5}}[/tex]

Option B

Answer:

t(12)=40 t(24)=-3.2

Step-by-step explanation:

t(12)=40 because, if you replace 12 with t in the equation, everything but 40 cancels out.

t(24)=-3.2 because, if you plug in 24 for t it will be the same as the first equation where t is 0.

Answer:

You would multiply by 1728.

So 10 cubic feet = 10 * 1728 = 17,280 cubic inches.

Step-by-step explanation:

There are  12 inches in a foot so there are 12^3 = 1728 cubic inches in a cubic foot.

Final answer:

To convert 10 cubic feet to cubic inches, multiply the volume in cubic feet (10) by the conversion factor of 1,728 to get 17,280 cubic inches.

Explanation:

To change 10 cubic feet into cubic inches, you need to use the conversion factor that 1 cubic foot equals 1,728 cubic inches (since 1 foot equals 12 inches, cubing both sides gives us 123 = 1,728). You then multiply the volume in cubic feet by this conversion factor.

Here is the calculation step by step:

Start with the volume in cubic feet: 10 cubic feet.

Multiply this amount by the conversion factor to get the volume in cubic inches: 10 cubic feet * 1,728 cubic inches/cubic foot = 17,280 cubic inches.

So, 10 cubic feet is equal to 17,280 cubic inches.

let's recall that there are 16oz in 1 lbs, so then 12lbs is 12*16 = 192oz, plus 5, that makes it 197oz, so then 12lb 5oz is really 197oz.

likewise, 7lb is 7*16 = 112oz, plus 10 that makes it 122oz.

197 - 122 = 75 oz

and 75 oz is just 16+16+16+16+11, 4lbs and 11 oz.

The formula for slope is

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

In this case...

Answer:

C

Step-by-step explanatio

33 + 33 + 38 + 35 +37 + 40 + 57 = 273

273 / 7 = 39

33 + 33 + 38 + 35 +37 + 40 = 216

216 / 6 = 36

The mean (average) of the data set without the outlier is 36 and including the outlier is 39. The outlier here being the value 57 which deviates most from the other values in data set.

To find the mean (or average) of a data set, you add all the values together and then divide by the count of the values.

Firstly, for the mean without the outlier, we add 33+33+38+35+37+40 = 216, which we then divide by the 6 values, giving us 36. So, the mean without considering the outlier is 36.

For the mean considering all values including the outlier (57), calculate 33+33+38+35+57+37+40 = 273, then divide by the 7 values, which gives us approximately 39. The answer to the nearest tenth is 39.0. Therefore, the mean of this data set with the outlier is 39.0 and without the outlier is 36.0.

Answer:

Step-by-step explanation:

Note that (x^a)^b = x^ab.

Thus,  (x^2/3)^4/5 = x^(2/3 * 4/5) = x^(8/15)

To simplify the expression (x^2/3)^4/5, multiply the exponents and provide the resulting exponent x^8/15.

To simplify the expression (x2/3)4/5, we can use the rule of exponents which states that when raising a power to another power, we multiply the exponents. In this case, the exponent 4/5 applies to both the x and the 2/3. Multiplying the exponents gives us 2/3 * 4/5 = 8/15. Therefore, the simplified expression is x8/15.

Answer:

5ab+a-4

Step-by-step explanation:

Answer:

Step-by-step explanation:

First you must calculate the module or the magnitude of both vectors

The module of u is:

[tex]|u|=\sqrt{(8)^2 + (-3)^2} \\\\|u|=\sqrt{64 + 9}\\\\|u|=8.544[/tex]

The module of v is:

[tex]|v|=\sqrt{(-3)^2 + (-8)^2} \\\\|u|=\sqrt{9 + 64}\\\\|u|=8.544[/tex]

Now we calculate the scalar product between both vectors

[tex]u*v = 8*(-3) + (-3)*(-8)\\\\u*v = -24+ 24=0[/tex]

Finally we know that the scalar product of two vectors is equal to:

[tex]u*v = |u||v|*cos(\theta)[/tex]

Where [tex]\theta[/tex] is the angle between the vectors u and v. Now we solve the equation for [tex]\theta[/tex]

[tex]0 = 8.544*8.544*cos(\theta)\\\\0 = cos(\theta)\\\\\theta= arcos(0)\\\\\theta=90\°[/tex]

the answer is 90°

Whenever the scalar product of two vectors is equals to zero it means that the angle between them is 90 °

The Fahrenheit temperature range at which the antifreeze protects the car, converted from Celsius, is -40°F ≤ F ≤ 284°F.

To convert the Celsius range to a Fahrenheit range, you can use the conversion formula, F = (9/5)*C + 32. Using this formula, for -40°C the Fahrenheit equivalent would be F = (9/5)*(-40) + 32 which equals -40°F, and for 140°C the Fahrenheit equivalent would be F = (9/5)*(140) + 32 = 284°F. Therefore, the compound inequality representing the Fahrenheit temperature range at which the antifreeze protects the car is -40°F ≤ F ≤ 284°F.

Step-by-step explanation:

Let's start with the y-intercept.  (0, 50) is shifted 10 units to the right and becomes (10, 50).  Next, we know the slope is 5.  We can use this to plot more points, or we can use it to write an equation in point-slope form:

y - 50 = 5 (x - 10)

y - 50 = 5x - 50

y = 5x

So the new y-intercept is (0, 0).

What this means is that Jeremy's savings account will be worth $50 in ten years.

If we compare the new y-intercept to the old one, we see that the 10 unit shift to the right is the same as a 50 unit shift down.  Shifting graph B up 50 units will bring us back to the original graph.

Answer:

The vertical asymptote is at P = 100

Step-by-step explanation:

* Lets explain what are the vertical asymptotes

- Vertical asymptotes are vertical lines which correspond to the zeroes

  of the denominator of a rational function

- Vertical asymptotes can be found by solving the equation n(x) = 0

  where n(x) is the denominator of the function t(x)/n(x)

- Note: this only applies if the numerator t(x) is not equal zero for the

 same value of x

# Example: to find the vertical asymptote to [tex]f(x)=\frac{3x-1}{x-5}[/tex]

  put the denominator x - 5 = 0, and solve it

  the value of x = 5, then the vertical asymptote is at x = 5

* Lets solve the problem

- The equation of the cost is [tex]C=\frac{25000P}{100-P}[/tex]

∵ The denominator of C is (100 - P)

- To find the vertical asymptote equate the denominator by zero

∴ 100 - P = 0 ⇒ add P for both sides

∴ P = 100

∴ There is a vertical asymptote at P = 100

* The vertical asymptote is at P = 100

Answer:

a) x = 21

b) 136º

Step-by-step explanation:

The sum of all the angle measures within a triangle is equal to 180º. Therefore, we can use an equation to find x and find the measure of angle C.

x + 6x + 10 + x + 2 = 180

Let's add together all the x's.

8x + 10 + 2 = 180

Now let's add together 10 + 2.

8x + 12 = 180.

To solve for x, we must first isolate 8x. To do this, we subtract 12 from both sides.

8x + 12 - 12 = 180 - 12.

8x = 168

To solve for x, we must divide 8 from both sides.

8x / 8 = 168 / 8

x = 21

Now we have the answer to the first part.

We can use this answer to solve for the measure of angle C.

Angle C = 6x + 10.

We just have to plug in 21 for x and solve for angle C.

6(21) + 10 = 136.

Angle C has a measure of 136º.

19 hours

It will take 19 hours of lessons.

An equation is formed of two equal expressions. The answer describes the correct solution for the situation It will take 19 hours of lessons. The correct option is D.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that Ahmet rents a piano for $35 per month. He earns $25 per hour giving piano lessons to students. Therefore, the profit earned by Ahmet will be,

Profit = Total Earning - Expenditure

Profit = Total Earning - Cost of renting the piano

Profit = $25x - $35

Where x represents the number of hours

Now, since Ahmet wants to earn a profit of $440, this month. Therefore, we can write,
$440 = $25x - $35

$440 + $35 = $25x

$475 = $25x

x = $475 / $25

x = 19

Thus, Ahmet needs to give 19 hours of lessons in order to earn $440 profit.

Hence, the answer describes the correct solution for the situation is It will take 19 hours of lessons.

Answer:

c=ab/(2b+a)

Step-by-step explanation:

20^c = 4^c  *  5^c

20^c=  (2^2)^c   * 5^c

20^c= (2 )^(2c)   * ( 5 )^c

Raise both sides to power a

20^(ca)=(2^a)^(2c)  * (5  )^(ac)

20^(ca)=(20^c)^(2c) * (5  )^(ac)

Raise both sides to power b

20^(cab)=(20)^(2c^2b)*(5^b)^(ac)

20^(cab)=20^(2c^2b) * (20^c)^(ac)

20^(cab)=20^(2c^2b) * 20^(ac^2)

Rewriting using law of exponents on right hand side

20^(cab)=20^(2c^2b+ac^2)

Now bases are same so that means the exponents have to be the same, that is we have:

cab=2c^2b+ac^2

assuming c is not 0, divide by c on both sides

ab=2cb+ac

Factor the right hand side

ab=c(2b+a)

Divide both sides by (2b+a)

c=ab/(2b+a)

C  is expressed in terms of b as c = [tex](5^b) / 2.[/tex]

To express c in terms of b in the equation [tex]2^a = 5^b = 20^c[/tex], we need to use the property of exponents that states:

[tex]a^(m * n) = (a^m)^n[/tex]

Let's first express [tex]20^c[/tex] in terms of 2 and 5:

[tex]20^c = (2^2 * 5)^c = 2^(2c) * 5^c[/tex]

Now, we have the equation:

[tex]2^a = 5^b = 2^(2c) * 5^c[/tex]

Since the bases (2) and (5) are equal, the exponents must also be equal:

a = 2c

Now, we can express c in terms of b:

Divide both sides of the equation by 2:

c = a/2

Since we know that a = [tex]5^b[/tex], we can substitute it into the equation:

[tex]c = (5^b) / 2[/tex]

So, c is expressed in terms of b as c = (5^b) / 2.

Answer:

x = 14 and z = 96

Step-by-step explanation:

The 2 marked angles are vertical and congruent, hence

9x - 42 = 5x + 14 ( subtract 5x from both sides )

4x - 42 = 14 ( add 42 to both sides )

4x = 56 ( divide both sides by 4 )

x = 14

Hence 5x + 14 = (5 × 14) + 14 = 70 + 14 = 84°

z and 5x + 14 form a straight angle and are supplementary, hence

z + 84 = 180 ( subtract 84 from both sides )

z = 96

T(x) = 88 + 12x

Step-by-step explanation:

Givens:

1st hour = 100 copies

subsequent hours s(x) = 12( x - 1), where x is number of hours

Let total sales be represented by T(x)

Total sales, T(x)

= sales in first hour + sales in subsequent hours

=  100 + 12 (x - 1)

= 100 + 12x - 12

= 88 + 12x

Answer: Total sales function is [tex]S(x)=88+12x[/tex]

Step-by-step explanation:

Since we have given that

Number of copies the first hour he sell at a local game = 100

Sales function is expressed as

[tex]s(x)=12(x-1)=12x-12[/tex]

so, function that shows total sales including the first hour is given by

[tex]S(x)=100+s(x)\\\\S(x)=100+12x-12\\\\S(x)=88+12x[/tex]

values that are excluded from the domain of a rational expression are values that make the denominator 0, since if that's so, the rational will be undefined.  That happens when the denominator is zero out, let's do so

[tex]\bf mn+3m=0\implies m(n+3)=0\implies \begin{cases} m=0\\ n=-3 \end{cases}[/tex]

so, if ever m = 0, the denominator will become 0 and the rational becomes undefined, and whenever n = -3, the same will happen to the rational, thus those values are excluded.

Final answer:

The excluded values for the expression (m + 5) / (mn + 3m) are m = 0 and n = -3, as these would make the denominator equal to zero, which is undefined.

Explanation:

The question appears to relate to the concept of excluded values in an algebraic expression, specifically one that involves division by a variable term. The excluded values are the values that the variables cannot take on because they would make the denominator equal to zero, which is undefined in mathematics. However, the given information seems to be related to physics, particularly quantum mechanics, which involves quantum numbers and the Pauli exclusion principle. It is important to have the correct expression to identify the excluded values properly. Assuming the expression is (m + 5) / (mn + 3m), we need to determine the values of m and n that would make the denominator zero.

To find the excluded values for the variable m and n, we need to set the denominator equal to zero and solve for the variables:

mn + 3m = 0

m(n + 3) = 0

From this, we can see that m must not be zero, and when m is not zero, n must not be -3. Therefore, the excluded values are m = 0 and n = -3.
