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

Find the size of the angle yzx. Give your answer to 3 significant figures
Answer:
∠ YZX ≈ 19.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinZ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{YZ}[/tex] = [tex]\frac{7.5}{22.3}[/tex] , then
∠ YZX = [tex]sin^{-1}[/tex] ([tex]\frac{7.5}{22.3}[/tex] ) ≈ 19.7° ( to 3 significant figures )

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].

Answer:
16
Step-by-step explanation:
So, we know it isn't D. We've narrowed it down to the top 3 answers now we would have to Divide 39 and 7 that would equal to 19.5. So, it could be A or B now. It says less 7 years, so we would know have to do this 39 - 7 = 32 32 / 2 = 16.
Therefore your answer is 16

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
What are the zeros of the function f, where f(x)=6x^2-9x-6
Answer:

Step-by-step explanation:

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.

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

Prove that when a polynomial function p(x) is divided by a first degree polynomial ax + b the remainder is p(-b/a)
Answer:
r = p(-b/a)
Step-by-step explanation:
Let p(x) = q(x)(ax + b) + r(x) where q(x) is the quotient when p(x) is divided by ax + b and r(x) is the remainder.
Since ax + b is a first degree polynomial, r(x) is one power less than ax + b is is just a constant, r.
So, p(x) = q(x)(ax + b) + r
Now, p(x) = r when q(x)(ax + b) = 0
since q(x) ≠ 0, ax + b = 0 ⇒ ax = -b ⇒ x = -b/a
⇒ p(x) = r when x = -b/a
So, r = p(-b/a)
So, the remainder when a polynomial function p(x) is divided by a first degree polynomial ax + b is p(-b/a)

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.
