Answer:
15/56
Step-by-step explanation:
3*5=15 * 8*7=56
15/56
Final answer:
To multiply fractions 3/8 and 5/7, multiply the numerators to get 15 and the denominators to get 56, resulting in the fraction 15/56, which is in its simplest form.
Explanation:
To multiply two fractions, you multiply the numerators (the top numbers) together and then multiply the denominators (the bottom numbers) together. So for the fractions 3/8 and 5/7, you would do the following:
Multiply the numerators: 3 x 5 = 15Multiply the denominators: 8 x 7 = 56Therefore, the product of these two fractions is 15/56. This fraction is already in its simplest form because the numerator and the denominator do not have any common factors besides 1.

an energy plant is looking into putting in a system to remove harmful pollutants from its emissions going into Earth's atmosphere. The cost of removing the pollutants can be modeled using the function C = 25000P/100 -P what is the vertical asymptote?
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:
The correct answer options are C. [tex]\frac{x^2+5}{x-8}[/tex] and D. [tex]\frac{x^2-x-56}{x^2-64}[/tex].
Step-by-step explanation:
The values which make the denominator equal to zero are called the excluded values.
Here, we can substitute 8 for x and check if it makes the denominator 0.
[tex]\frac{x-8}{x+8} = \frac{8-8}{8+8} =\frac{0}{16} =0[/tex]

475÷25=h
h=19
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.
What is an equation?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.

Rewrite the equation in standard form using integers.
Answer:
[tex]\large\boxed{y-4=\dfrac{9}{2}(x+5)}\\\boxed{9x-2y=-53}[/tex]
Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The label on the car's antifreeze container claims to protect the car between −40°C and 140°C. To covert Celsius temperature to Fahrenheit temperature, the formula is C=5/9(F-32). Write a compound inequality to determine the Fahrenheit temperature range at which the antifreeze protects the car.
The Fahrenheit temperature range at which the antifreeze protects the car, converted from Celsius, is -40°F ≤ F ≤ 284°F.
Explanation: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.

C 39, 36
B 39, 30.9
D 45.5, 30.9
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.
Explanation: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.

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.

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

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

Step-by-step explanation:
2^a = 5^b = 20^c, express c in terms of and b
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.

which polynomial could be represented by this graph?
Answer:
[tex]x(x+2)(x-1)(x-3)^2[/tex]
Please let me know the choices to better help you.
Step-by-step explanation:
I see zeros at x=-2 , x=0 , x=1 , x=3.
Any time it makes like a little U or upside down U at a zero you are going to have a even power on your factor (for which the zero occurs). If it goes through the zero increasing or decreasing (not making a kind of U shaped upside down or upside right), it is an odd power.
So at x=-2, (x+2) is going to have an odd power
So at x=0, (x-0) or (x+0) or even just x is going to have a odd power
So at x=1, (x-1) is going to have an odd power
So at x=3, (x-3) is going to have an even power
So the polynomial could be represented by
[tex]x(x+2)(x-1)(x-3)^2[/tex]

Which expression is equivalent to
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]
