A CD usually sells for $13.00. If the CD is 30% off, and sales tax is 5%, what is the total price of the CD, including tax?
Answer:
$9.56
Step-by-step explanation:
$13.00 x .30 = 3.90
13.00 - 3.90 = $9.10 x .05 = 0.46

Write the ratio 4/7 over 1/8 in simplest form. How is the simplest form of the ratio 4/7 over 1/8 related to the simplest form of the ratio 1/8 over 4/7
Answer:
Step-by-step explanation:
Ratio = 4/7 : 1/8
[tex]=\frac{\frac{4}{7}}{\frac{1}{8}}\\\\=\frac{4}{7}*\frac{8}{1}\\\\=\frac{32}{7}[/tex]
= 32 : 7
[tex]\frac{\frac{1}{8}}{\frac{4}{7}}=\frac{1}{8}*\frac{7}{4}\\\\=\frac{7}{32}[/tex]
= 7 : 32
Ratio 4/7 over 1/8 is the multiplicative inverse of the ratio 1/8 over 4/7
What are the zeros of the function f, where f(x)=6x^2-9x-6
Answer:
x=NEGATIVE 1/2, POSITIVE 2
Step-by-step explanation:
Just use math.waycom
The non-negative zero of the function f(x) is x = 2.
What are zeros of quadratic function?The zero of the function is where the y-value is zero. The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.
here, we have,
For a given function f(x), the "zeros" of the function are the values of x such that:
f(x) = 0
In this case, we have the function:
f(x) = 6*x^2 - 9*x - 6
If we want to find the zeros of this function, we need to solve:
f(x) = 0 = 6*x^2 - 9*x - 6
To solve this, we can use the Bhaskara's formula, which says that for a general quadratic equation:
0 = a*x^2 + b*x + c
The zeros are:
x = -b ±√b² - 4ac / 2a
In this case our equation is:
0 = 6*x^2 - 9*x - 6
then, in the above notation, we have:
a = 6
b = -9
c = -6
Replacing these in our general formula, we get:
x = 9±15 /12
Then we have two zeros:
x = (9 + 15)/12 = 24/12 = 2
x = (9 - 15)/12 = -6/12 = -1/2
But we want only the non-negative, so we can discard the second one.
Concluding, the non-negative zero of the function f(x) is x = 2.

11. The speed limit in a residential neighborhood is 35 miles per hour. This is one half
the speed of a major interstate highway a few miles away
What is the speed of the major highway?
Answer:
35*2 = 70
70 mph on the Major Highway
Step-by-step explanation:
Answer:
70
Step-by-step explanation:
if 35 is half of x (x being the speed of a major interstate highway a few miles away) then this means [tex]\frac{x}{2} =35[/tex] you multipliy both sides by 2 to get x by its self and now have x=70

1 If angle DAC is 40 degrees how many degrees is Angle ACD. Show all of your work. Show Your work
Answer:
m<ACD = [tex]50^{o}[/tex]
Step-by-step explanation:
From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.
In the triangle ACD:
<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)
<ACD + 40 + 90 = 180
<ACD + 130 = 180
<ACD = 180 - 130
<ACD = [tex]50^{o}[/tex]
With the application of the property of the sum of interior angles of a triangle, the measure of <ACD is [tex]50^{o}[/tex].
There is a total of 45 boys and girls in a choir.
The mean age of the 18 boys is 16.2 years.
The mean age of the 27 girls is 16.7 years.
Calculate the mean age of all 45 boys and girls.
Answer:
16.5 year
Step-by-step explanation:
Using, mean = sum/no. *of observations
Here,
=> 16.2 = (sum of ages of boys)/18
=> 16.2 x 18 = sum of ages of boys
=> 291.6 = sum of ages of boys
Similarly, sum of ages of girls = 27 x 16.7 = 450.9
Mean(total) = (sumof agesof boys + girls)/45
Mean = (291.6 + 450.9)/45 = 16.5
Answer:
The mean age of all 45 boys and girls is 16.5years
Step-by-step explanation:
Since the mean age of the 18 boys is 16.2years,
∴ Sum of their ages = 18 × 16.2
= 291.6years
The mean age of the 27 girls is 16.7years
∴ Sum of their ages = 27 × 16.7
= 450.9years
∴ Mean age of all 45 boys and girls = [tex]\frac{291.6 + 450.9}{45}[/tex] years
= [tex]\frac{742.5}{45}[/tex] years
= 16.5 years
∴ The mean age of all 45 boys and girls is 16.5 years.
A container can hold 18 litres of liquid. If there 7 2/3 litres of watee was poured into it, how much more water is needed to fill that container?
Answer:
Step-by-step explanation:
1 full container = 18 Liters.
The amount in the container = 7 2/3
The amount left to go is 18 - 7 2/3
Now I don't know how you have been taught to do this, but I think the easiest way is to make 18 = 17 3/3 If you do that then the 5 will be subtracted from the 17 and the 2/3 will be subtracted from the 3/3
17 - 5 = 12
3/3 - 2/3 = 1/3
So the answer is 12 1/3
Identify the slope and y-intercept of the graph of the equation y=12x−5 . slope:__
The slope is 12 and y- intercept is -5.
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
y=12x−5
Now, from slope- intercept form
y = mx + b
where m is the slope and b is the y intercept.
Now, Comparing with given equation
m= 12 and b= -5
Hence, the slope is 12 and y- intercept is -5.

Step-by-step explanation:
Samuel spends $8 on lunch. The tax rate is 9%. What is his total cost?
Answer:
$8.72
Step-by-step explanation:
Since the tax rate is 9% of the lunch cost, the tax for this lunch is .72 dollars since 9% of 8 is 0.72(see math below). You add the 0.72 to 8 and the total cost is $8.72.
8 x (9/100) = tax
8 x 0.09 = 0.72
8+0.72 = $8.72
Write 45 cents as a percentage of 18 dollars
