Step-by-step explanation:
a triangle has 180 degrees in total
so adding the angles altogether we get 180
set the equation up like this
6x + 3 + 75 + 60 = 180
and then combine like terms
6x + 138 = 180
then subtract
6x = 42
and then finally divide
x = 7
Answer:
A) 7
Step-by-step explanation:
180-60=120
120-75= 45
45-3=42
42/6= 7
A) 7

If lines l and m are parallel find the value of X
3x+4y-12=0
make y the subject of the equation
Answer:
y = -¾x + 3
Step-by-step explanation:
Given the equation in standard form, 3x + 4y - 12 = 0, we must isolate the y in order to make it the subject of the equation.
The first step is to add 12 to both sides of the equation:
3x + 4y - 12 + 12 = 0 + 12
3x + 4y = 12
Next, subtract 3x from both sides:
3x - 3x + 4y = - 3x + 12
4y = -3x + 12
Lastly, divide both sides by 4 to isolate y:
[tex]\frac{4y}{4} = \frac{-3x + 12}{4}[/tex]
y = -¾x + 3
A recipe for pasta noodles calls for 12 eggs for every 8 cups of flour. How many eggs are needed when 2 cups of flour are used?
Answer:
3 eggs
Step-by-step explanation:
12/8 = 1.5 eggs per cup of flour and so, multiplied by 2, 3 eggs.
Engineers are draining a water reservoir until its depth is only 10 feet. The depth decreases exponentially as
shown in the graph below. The engineers measure the depth after 1 hour to be 64 feet and after 4 hours to be
28 feet. Develop an exponential equation in y=a(6)" to predict the depth as a function of hours draining.
Round a to the nearest integer and b to the nearest hundredth. Then, graph the horizontal line y = 10 and
find its intersection to determine the time, to the nearest tenth of an hour, when the reservoir will reach a
depth of 10 feet.
The draining of the reservoir follows an exponential function
The reservoir will reach a depth of 10 feet at 7.6 hour
The given parameters are:
[tex]\mathbf{(x,y) = (1,64)(4,28)}[/tex]
An exponential equation is represented as:
[tex]\mathbf{y = ab^x}[/tex]
Substitute [tex]\mathbf{(x,y) = (1,64)(4,28)}[/tex] in [tex]\mathbf{y = ab^x}[/tex]
[tex]\mathbf{64 = ab^1}[/tex]
[tex]\mathbf{64 = ab}[/tex]
[tex]\mathbf{28 = ab^4}[/tex]
Divide [tex]\mathbf{64 = ab}[/tex] and [tex]\mathbf{28 = ab^4}[/tex]
[tex]\mathbf{\frac{ab^4}{ab} = \frac{28}{64}}[/tex]
[tex]\mathbf{b^3 = 0.4375}[/tex]
Take cube roots
[tex]\mathbf{b= 0.76}[/tex]
Substitute [tex]\mathbf{b= 0.76}[/tex] in [tex]\mathbf{64 = ab}[/tex]
[tex]\mathbf{64 = 0.76a}[/tex]
Solve for a
[tex]\mathbf{a = 84}[/tex]
So, the equation is:
[tex]\mathbf{y = 84(0.76)^x}[/tex]
See attachment for the graphs of [tex]\mathbf{y = 84(0.76)^x}[/tex] and y = 10
The point of intersection is: x = 7.6
Hence, the reservoir will reach a depth of 10 feet at 7.6 hour

By computing the difference between consecutive y-values of the table, we can see that the one that represents a linear function is the first one (from the left).
How to identify the linear function?A linear function is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
Notice that if we evaluate this in x + 1, we get:
y = a*(x + 1) + b = (a*x + b) + a.
So for each increase of 1 unit in the x-variable, we must have an increase of a units in the y-variable.
So you need to see that the difference between the consecutive values of y on the tables is a constant. The only table that meets this condition is the first one, where the common difference is 0.5, so the table that represents a linear function is the first one (from the left).

175 calories in 12 oz
Answer:
The answer is 14.58
Step-by-step explanation:
Please mark brainliest and hope this helps!
Answer:
Unit rate is 14.58 cal/oz.
Given:
total calories = 175
total ounces = 12
Simply divide the total number of calories by the total number of ounces to get the unit rate of calories per ounce.
175 calories ÷ 12 ounces = 14.58 calories per ounce.

what is the importance of derivative classification?
Answer:
Classifying information helps to protect our national security
#Brainly lovers
The importance of derivative classification lies in its role in safeguarding sensitive information and ensuring national security. Derivative classification involves the process of determining the level of classification of information that is derived from a primary source.
what is the importance of derivative classification?Derivative classification is an essential aspect of information security and classification systems. It involves assigning the appropriate level of classification to information that is derived from a primary classified source. This process ensures that the derived information is protected and handled with the same level of care as its source material.
The importance of derivative classification lies in several key factors. Firstly, it helps prevent unauthorized disclosure of sensitive information. By classifying derived information, access to it can be controlled, limiting its availability to individuals with appropriate security clearances. This restriction ensures that only authorized personnel can access and handle the information, reducing the risk of it falling into the wrong hands.
Derivative classification promotes information sharing within authorized channels. When information is properly classified, it can be shared securely among individuals or organizations that have the necessary clearances. This controlled sharing allows for effective collaboration and coordination among different entities while maintaining the confidentiality of the information.

What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
Given,
f(x) = x²
g(x) = shifts graph downward by 2 units and reflected down.
Now,
The value of f(x) for positive x will be positive
But the value of g(x) for positive x is negative and 2 units shifted downward.
So it should be -x² - 2.
Hence"The value of g(x) will be -x² + 2 so option (C) will be correct".
