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].

Addison and Alexa find ½ + ⅙. Addison says the sum is 4/6. Alexa says the sum is ⅔. Who is correct? Explain your reasoning.
Answer:
They are both correct. When the fractions are added, the sum is 4/6. 4/6 is not in its simplest form yet. It can be simplified by dividing the numerator and the denominator by 2. When divided by 2, it yields 2/3
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{6}[/tex]
[tex]\frac{3 + 1}{6}[/tex] = 4/6 = 2/3

3x3x3 which equals 27 and them divide it by 3 which is 9, and subtract -1 from it, which then you have to add so its 10.
Answer:
27/4
Step-by-step explanation:
In this question,
[tex]x = 3 \\ y = - 1[/tex]
So if we substitute this in the equation given below
[tex] {x}^{3} \div 3 - y[/tex]
So if we substitute the variables,
[tex] {3}^{3} \div 3 - ( - 1) \\ [/tex]

Jasmine will buy the same number of stamps every month to add to a stamp collection her grandfather gave her. The table shows the number of stamps Jasmine will have at the end of x months. How many stamps was Jasmine given, and how many stamps will she buy every month?
A. Jasmine was given 65 stamps, and she will buy 5 stamps every month.
B. Jasmine was given 60 stamps, and she will buy 65 stamps every month.
C. Jasmine was given 5 stamps, and she will buy 60 stamps every month.
D. Jasmine was given 60 stamps, and she will buy 5 stamps every month
Answer:
It is D
Step-by-step explanation:
It could be A but if we read the sentence correctly than we should understand about the number of stamps she bought in every month and how much her grandmother gave her.We should also read the options more than 10 times to understand it

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

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.

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.
