At lunch, kira eats either a burrito containing 490 milligrams of sodium or a peanut butter sandwich containing 700 milligrams of sodium. her doctor told her to reduce her sodium to no more than 4,000 milligrams per week. which inequality represents x, the number of microwave burritos, and y, the number of peanut butter sandwiches, she can eat each week? 490x 700y < 4000 490x 700y ≤ 4000 490x 700y > 4000 490x 700y ≥ 4000
Answers
The inequality represents x, and y, she can eat each week is,
490x+700y \leq 4000.
x be the number of microwave burritos
y be the number of peanut butter sandwiches
we know that
[tex]490x+700y \leq 4000[/tex].........inequality that represents the situation
What is the meaning of inequality?The mathematical expression in which the sides of an equation are not equal to each other.

1. Avenue A runs parallel to Avenue B, and Avenue C runs diagonally across the two streets. Use the marked angles to write and solve an equation to find the value of x. 10x + 6 Avenue A 6x – 18 Avenue C Avenue B
Answers
The value of the equations related to the angle system related to the two parallel lines (avenues A and B) cut by a third diagonal line (avenue C) is equal to to 12.
How to determine the value of x from a system of angles
In this question we must apply all Euclidean theorems of angles between two parallel lines cut by a third diagonal line. The internal angle between avenues B and C equals 6 · x - 18 and the external angle between avenues A and C equals 10 · x + 6.
By alternate internal angles between parallel lines we infer the measure of the internal angle between the avenues A and C equals 6 · x - 18, and definition of supplementary angles we have the following expression:
(6 · x - 18) + (10 · x + 6) = 180
16 · x - 12 = 180
16 · x = 192
x = 12

Nadia needs one cup of ice cream for every student in her class for their year-end party. The ice cream is only sold in pints. If there are 24 students in her class, how many pints of ice cream will she need? Describe how to solve this problem.
Answers
Using proportions, it is found that she will need 12 pints of ice cream.
What is a proportion?A proportion is a fraction of a total amount.
Each cup is equivalent to 0.5 pints. There are 24 students, and each student needs a cup, hence 24 cups are needed.
In pints, the equivalent amount is given by:

The radius of a circle is 19m. Find its area to the nearest whole number.
Answers
1134.11m²
______----------________
Answer:
1134.11
Step-by-step explanation:
The problem with this equation is pi is an angle in radians. It has a never ending number of digits.
The area of a circle is basically a square r x r rotated through 180 degrees around the squares centre.
So the area can be written as 180 x 19 x 19 = 64980 degrees meters square.
This is a finite number. The area of a circle does not change. Pi r squared has an ever increasing result.
pi is a conversion factor between the finite areas of circles and the area in square units which can never have a result that is finite as squares cannot fill a circle, no matter how small.
To convert the round finite area to m squared you divide the area by 180/pi = 57.295779513 degrees per radian.
Area in degrees meters Squared 64980/ 57.295779513.
= 1134.1149479 radian meters squared.

The table below shows the value of a car during certain years . Using an exponential model , write an equation for the curve of best fit, then estimate the value of the car in 2016 .
Answers
The exponential function that gives the value of the car in t years after 2008 is:
[tex]A(t) = 27500(0.88)^t[/tex].
Using the function, the estimate for the value of the car in 2016 is of $9,900.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem:
The initial value is of A(0) = 27,500.Considering the first year change, we have that 1 - r = 24200/27500 = 0.88.Hence, the equation is:
[tex]A(t) = 27500(0.88)^t[/tex]
2016 is 8 years after 2008, hence the value of the car will be given by:
[tex]A(8) = 27500(0.88)^8 = 9900[/tex]

The exponential function is given as y = 27500(0.88)ˣ and the value of the car in 2016 is $9890
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Let y represent the value of the car after x years after 2008, hence:
at x = 0, y = 27500
27500 = ab⁰
a = 27500
At x = 1, y = 24200, hence:
24200 = 27500b¹
b = 0.88
y = 27500(0.88)ˣ
In 2016, x = 8, hence:
y = 27500(0.88)⁸ = 9890

Which equation best represents the relationship between x and y in the graph?
Answers
Answer:
C is your correct answer : y = 2x + 3
Step-by-step explanation:
Your answer choices are all in slope-intercept form.
Slope-Intercept Form: y=mx+b
First, you need to find the y-intercept.
Coordinate Point: (0,3) is your y-intercept.
Now, you need to find the slope.
This slope is positive.
There's another point (1,5).
This point is important because you can start at your y-intercept and rise and run to get to (1,5).
You have to rise up 2 and go over to the right 1.
2/1 is your slope but simplified is 2.
Your formula: y = 2x + 3

Enter your answers and your work or explanation in the box provided.

Answer:
x=9.167
Step-by-step explanation:
12x+240=350
350-240 because you are getting rid of 240 to get 12x by itself so you must do it on the other side.
12x=110, then you do 12x/12 and 110/12
x=9.167
Answer: Approimately $9.16
Step-by-step explanation:
In this problem, you have to solve for x variable.
1. Distribute the 12 to the x + 20 which is 12x + 240
2. Subtract 240 from both sides so 350 - 240 is 110.
3. Now your equation is 110 = 12x
4. Divide 12 on both sides. But 12 doesn't go into 110 perfectly.
5. 110 divided by 12 is approximately 9.16.
The x represent how much the student has earn extra to get $350 in 12 months. The student has to earn 9.16 dollars every month on top of the 20 dollars.

Which of the following shows the correct first step to solve x^2 - 16x = -21 by completing the square?
A)x^2 - 16x + 64 = -21
B) x^2 - 16x + 64 = -21 + 64
C) x^2 - 16x + 16 = -21 + 16
D) x^2 - 16x + 8 = -21 + 8
Answers
Answer:
I believe the answer would be B) x^2 - 16x + 64 = -21 + 64
Step-by-step explanation:
When you're completing the square you take the "middle" term (in this case it's -16) and you divide it by two, then square it. By doing that for this problem you get 64 (16/2 = 8 - 8^2 = 64; signs don't matter in this case because you multiply 2 negatives). You have to add that 64 to BOTH sides so that the equation evens out.
Ultimately, with it factored, the answer will be (x-8)^2

Answers
Answer:
Option 2: (1, 0) and (0, -5)
Step-by-step explanation:
Let's solve this system of equations using the elimination method.
Start by labelling the two equations.
5x -y= 5 -----(1)
5x² -y= 5 -----(2)
(2) -(1):
5x² -y -(5x -y)= 5 -5
Expand:
5x² -y -5x +y= 0
5x² -5x= 0
Factorise:
5x(x -1)= 0
5x= 0 or x -1= 0
x= 0 or x= 1
Now that we have found the x values, we can substitute them into either equations to solve for y.
Substitute into (1):
5(0) -y= 5 or 5(1) -y= 5
0 -y= 5 or -y= 5 -5
y= -5 or -y= 0
y= 0
Thus, the solutions are (0, -5) and (1, 0).
