The equation, in slope-intercept form to represent the monthly price
as a function of the number of MB used is y = mx + c.
It is given in the question that the cell phone provider charges you
$35 a month for a phone plan and charges $0.12 per MB of data used.
Hence,
Total monthly charges = MB used*Charge per MB+ Fixed charge
Let y represents total monthly charges
x represents the charge per MB
m represents the MB used and,
c represents the fixed charge
Therefore, we can write the above equation as:-
y = mx + c

Jeff found that one third bag of popcorn weighed 1/4 lb how many pounds will one full bag of popcorn weigh
Based on the weight of one third bag of popcorn, one bag of popcorn weighs 3/4 lb
How to determine the weight of one bag?The statement is given as
One third bag of popcorn weighed 1/4 lb
This means that
1/3 bag = 1/4 lb
Multiply both sides of the equation by 3
So, we have the following equation
3 * 1/3 bag = 1/4 lb * 3
Evaluate the products
So, we have
3/3 bag = 3/4 lb

A cement walkway is to be poured .it is consists of the two rectangles with dimensions and a circle with radius 1.5 yards use 3.14 as an approximate value.how many square yards will the walkway be?If a painter it for 3.75 per square yard,how much will the painting cost?
The area of the walkway in square yards is 22.77 yards²
The cost of painting the walkway will be $85.37.
What is the area of the walkway?The square yards of the walkway can be determined by adding the areas of the two rectangles and the area of the quarter of a circle together.
Area of a rectangle = length x width
Area of the first rectangle = 9.5 x 1.5 = 14.25 yards²
Area of the second rectangle = 4.5 x 1.5 = 6.75 yards²
Area of a circle = πr²
Area of quarter of a circle = 1/4 × πr²
Where:
π = pi = 3.14
r = radius
1/4 x (3.14 x 1.5²) = 1.77 yards²
Area of the walkway = 1.77 yards² + 6.75 yards² + 14.25 yards² = 22.77 yards²
The cost of the painting can be determined by multiplying the area of the walkway by the cost per square yard.
Total cost = 22.77 yards² x 3.75 = $85.37

Assume the average test score from the last year's class was 85 points with a standard deviation of 9. By sketching a normal curve, which value below is the best estimate for the proportion of students earned a 70 points or higher?
The given information is:
- The average test score is 85 points
- The standard deviation is 9
- It is a normal distribution
We need to find the best estimate for the proportion of students earned a 70 points or higher.
First, we need to find the z-score for 70, by applying the following formula:
[tex]z=\frac{x-\mu}{\sigma},\text{ where }\mu=average,\sigma=standard\text{ }deviation,x=value[/tex]Then, as x=70, we replace the given values and find z:
[tex]z=\frac{70-85}{9}=\frac{-15}{9}=-1.67[/tex]Then, we can find the estimate as follows:
[tex]P(X\ge70)=P(z\ge-1.67)=1-P(z<-1.67)[/tex]Now, in a standard normal table, we search the cumulative probability of z<-1.67, and it is 0.0475:
Thus, replace this value to find P(X>=70):
[tex]P(X\ge70)=1-0.0475=0.9525[/tex]The probability is 0.9525, if we multiply it by 100%, we obtain: 95.25%
The best estimate is 95%.

tickets sold or 7 dollars and students sold for 4 dollars each how many of each type were sold
for the 5:30 show.
As a result, we deduce that 101 tickets were sold to adults and 171 to students after solving the algebraic equations.
What are Algebraic equations ?The term "algebraic equation" refers to a formulation of the equality of two expressions using the algebraic operations of addition, subtraction, multiplication, division, raising to a power, and extraction of a root on a set of variables.
A mathematical statement in which two expressions are rendered equal to one another is known as an algebraic equation.
So on the information provided to us:
we know that the total amount of the tickets sold =1694$
total no. of people = 272
Lets assume the no. of kids to be y and the adults to be x
So the first equation we get for the total no. of people is:
x+y=272...(i)
the next equation we get for the total amount of tickets sold will be equal to the no. of adults and children multiplied by the cost of each adult and child respectively :
7x+4y=1694....(ii)
Two solve both equations simultaneously , we multiply equation i with 4
we get:
4x+4y=1088
7x+4y=1694
on solving both the equations simultaneously we get
3x=606
x=101
putting value of x in equation (i) we get
y=171
Therefore, we conclude that the no. of tickets sold to adults were 101 and to students were 171.

Write the equation in slope intercept form;
-2y = 3x + 4
y = (-3/2)x - 2
m₂ = -3/2
m₁ ≠ m₂ as 2/3 ≠ -3/2
m₁×m₂ = 2/3 × -3/2 = -1
Thus, the both lines are perpendicular.
Part b: -2x + 3 y = -6
Write the equation in slope intercept form;
3y = 2x - 6

To help, but not give the answer so you can learn to do this:
To find the slope, choose any two points on the graph (no really IT DOESN'T MATTER WHICH ONE). Use the equation y-y/x-x to get the slope.
Ex. 8-3/5-1=4/3
(NOTE: Always write your answer as either an improper fraction or a whole number!)
To find the distance, go across the x-axis, however many units away the closest point is to your chosen point. Then, go across the y-axis for the required # of units. Next, find the total number of the x and y units. You can also subtract the smallest coordinate from the greatest if the two ordered pairs are in the same quadrant. If not in the same quadrant, add the coordinates together. If the value of x or y happens to be the same as your chosen coordinate, find the sum of the two numbers that are equal, or subtract if in the same quadrant.
Also, in case you have another question relating to the same line, the given line is NOT proportional. Just in case, though!

Skeletal muscle is striated, similar to cardiac muscle; it has long, thin, multinucleated fibers that are crossed in a regular manner by fine red and white lines that give the muscle its unique look. Myofibrils, which are made up of sarcomeres joined in series, make up muscle fibers. The arrangement of actin and myosin filaments, which results in the banding pattern of myofibrils, produces the striations of skeletal muscle. The ability of muscular tissue to contract is special.

How do we get our voice?
Answer: The lungs provide the airstream which powers human voice. As air is pushed up the windpipe from the lungs, the larynx, which is made up of two vocal folds, opens and closes to produce vibrations. These vibrations are carried through to the throat, nose, and mouth, which act as resonators- morphing the vibrations into distinct human sounds.
Step-by-step explanation:
Answer:
Our vocal cords gve us our voice.
Step-by-step explanation:
The vocal folds (cords) produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs. This vibration produces the sound wave for your voice.

The values of the trigonometry formulas are sin(240) = -sin(60), cos(225) = -cos(45) and tan(225) = tan(45)
How to determine the values of the trigonometry formulas?The trigonometry ratios are given as
sin(180 - ∅) = sin(∅)
cos(180 - ∅) = -cos(∅)
tan(180 - ∅) = -tan(∅)
Also, we have the following trigonometry ratios are given as
sin(180 + ∅) = -sin(∅)
cos(180 + ∅) = -cos(∅)
tan(180 + ∅) = tan(∅)
Using the above trigonometry ratios, we have
sin(240) = sin(180 + 60)
By comparison, we have
sin(240) = sin(180 + 60)
sin(180 + ∅) = -sin(∅)
This gives
∅ = 60
So, we have
sin(180 + 60) = -sin(60)
Evaluate
sin(240) = -sin(60)
Using the above trigonometry ratios, we have
cos(225) = cos(180 + 45)
By comparison, we have
cos(225) = cos(180 + 45)
cos(180 + ∅) = -cos(∅)
This gives
∅ = 45
So, we have
cos(180 + 45) = -cos(45)
Evaluate
cos(225) = -cos(45)
Using the above trigonometry ratios, we have
tan(225) = tan(180 + 45)
By comparison, we have
tan(225) = tan(180 + 45)
tan(180 + ∅) = tan(∅)
This gives
∅ = 45
So, we have
tan(180 + 45) = tan(45)
Evaluate
tan(225) = tan(45)
Hence, the value is tan(225) = tan(45)
