The total weight of cabbage is 14 1/4
What is Equation?An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
Given:
Yasmin purchased 6 heads of cabbage that each weighed 2 and 3/8 pounds.
So,
2 and 3/8 = 19/8
1 cabbage = 19/8 pounds
6 cabbages = x pounds
1 * x = 6 * 19/8
x = 114/8
x = 14 2/8
x = 14 1/4

Answer:
84 degrees
Step-by-step explanation:
Angle A = 83 degrees
Angle B = x degrees
Angle C = 135 degrees
Angle CDE = 122 degrees
We know that the four inner corners of a quadrilateral should add up to 360 degrees. Two supplementary angles will add up to 180 degrees. Adjacent angles on a straight line will always be supplementary. Knowing this, just solve for <ADC and add that amount to <A and <C. Then, subtract that sum from 360 degrees.
<ADC = 180-122 = 58
58+83+135 = 276
360-276 = 84 degrees
If three times a number added to 2 is divided by the number plus 4 the result is eight thirds. Find the number
Answer:
26
Step-by-step explanation:
(3a+2)/(a+4) = 8/3
(3a+2) = (8/3)(a+4)
(3a+2) = a*8/3 + 4*8/3
(3a+2) = 8a/3 + 32/3
3a - 8a/3 = 32/3 - 2
9a/3 - 8a/3 = 32/3 - 6/3
9a - 8a = 32 - 6
a = 26
Check:
(3*26 + 2) / (26+4) = 8/3
(78+2) / 30 = 8/3
80 / 30 = 8/3

In great detail, describe how to solve the advanced function below.
4^(8 - 2x) = 256
I understand the solution to the problem is (2). I would like a detailed description of how exactly to solve this problem.
The value of x in the equation is 2.
What is indices?Indices singular index is a branch of algebra that deals with the power or exponent of variables.
Laws of indices help us to evaluate indicial expressions and equations.
Analysis:
[tex]4^{8-2x}[/tex] = 256
Here 4 is the base number while 8-2x is the exponent or index.
So for us to evaluate this, we need to write 256 in its index form having its base as 4 also.
so 256 in base 4 index form is [tex]4^{4}[/tex]
[tex]4^{8-2x}[/tex] = [tex]4^{4}[/tex]
since both sides have the same base number, we equate only their exponent
8-2x = 4
-2x = 4 - 8
-2x = -4
x = -4/-2 = 2

y - 3x = 1
2y - X = 12
([?], [ ?])
Answer:
x = 2 , y = 7
Step-by-step explanation:
Since
y-3x = 1
y = 3x+1 - equation 1
2y-x = 12 - equation 2
Since we are using substitution method,
we will substitute equation 1 into equation 2.
[tex]2(3x + 1) - x = 12 \\ 6x + 2 - x = 12 \\ 5x + 2 = 12 \\ 5x = 12 - 2 \\ 5x = 10 \\ x = \frac{10}{5} \\ = 2[/tex]
Now we substitute x into equation 1 to find y.
[tex]y = 3(2) + 1 \\ = 6 + 1 \\ = 7[/tex]
Therefore x = 2, y = 7.

Miles is starting a tree farm. His plot of land is triangular with one side 36 feet and the other two sides 30 feet each. The height of this triangle-shaped plot is 24 feet. If each tree needs 8 square feet of space to grow, how many trees can Miles plant?
a. 35 b. 42 c. 54 d. 76
Answer:
54
Step-by-step explanation:
the plot of land is an isosceles triangle, meaning two sides and angles are the same in value.
height (h)= 24
base (b)= 36
length (l)= 30
solution
find the area of triangle using area=half the product of the base and height.
A=1/2(36×24)
A= 216 square feet.
each tree needs 8 square feet
therefore using ratio and proportion,
1 tree= 8 square feet
x trees= 216 square feet
cross multiply and it'll be
216/8=x
therefore x= 54 trees

On Friday, a local hamburger shop sold a combined total of 376 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Friday?
Answer:
94 hamburgers
Step-by-step explanation:
Let's solve this question through the use of equations.
Start by defining the variables used.
Let the number of hamburgers and cheeseburgers sold on Friday be h and c respectively.
Form 2 equations using the given information.
Given that the total sold is 376,
h +c= 376 -----(1)
The number of cheeseburgers sold was thrice the number of hamburgers sold.
c= 3h -----(2)
Solving by substitution:
Substitute (2) into (1):
h +3h= 376
Now that we have an equation expressed only in terms of h, we can find the value of h.
4h= 376
Divide both sides by 4:
h= 376 ÷4
h= 94
Thus, 94 hamburgers were sold on Friday.

For a certain company, the cost for producing x items is 60x+300 and the revenue for selling x items is 100x−0.5x2 .
The profit that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its profit, or at least wants to make a profit!
Part a: Set up an expression for the profit from producing and selling x items. We assume that the company sells all of the items that it produces. (Hint: it is a quadratic polynomial.)
Part b: Find two values of x that will create a profit of $50 .

Part c: Is it possible for the company to make a profit of $2,500 ?
The answers are
A. The equation for the profit from selling the items is P = 40x-0.5x²-300. b. The values of x are 10 and 70.c. It is not possible to have the profit of 2500How to solve for the expressionWe have the cost function in this question to be
C(x) = 60x+300
We have the function of the revenue to be
Revenue = 100x−0.5x²
A. The formula for revenue function is given
revenue - cost
This is expressed as
= (100x−0.5x²)-60x+300
We have to collect like terms and open the equation above.
This given us:
40x-0.5x²-300B. when profit = 50$
We have p = 40x-0.5x²-300
50 = 40x-0.5x²-300
Multiply the two sides by 10
This gives
500 = 400x - 5x² - 3000
This gives a quadratic equation
5x² - 400x - 3500 = 0
To solve the equation you have to make use of a quadratic calculator.
This gives us the values
x = 10x = 70c. We have P = 40x-0.5x²-300.
at P = 2500
2500 = 40x-0.5x²-300.
Multiply the equation by 10
25000 = 400x - 5x² - 3000
collect like terms
400x - 5x2 - 3000 +28000
400x -5x2 +28000
We have to take the discriminant
-400² - 4*5*28000
= -400000
The discriminant is negative hence it is not possible.

Step-by-step explanation:
[tex]y'' + \omega^2 y = 0[/tex]
has characteristic equation
[tex]r^2 + \omega^2 = 0[/tex]
with roots at [tex]r = \pm\sqrt{-\omega^2} = \pm|\omega|i[/tex], hence the characteristic solution is
[tex]y = C_1 e^{i|\omega|x} + C_2 e^{-i|\omega|x}[/tex]
or equivalently,
[tex]y = C_1 \cos(|\omega|x) + C_2 \sin(|\omega|x)[/tex]
With the given boundary conditions, we require
[tex]y(0) = 0 \implies C_1 = 0[/tex]
and
[tex]y'(\pi) = 0 \implies -|\omega| C_1 \sin(|\omega|\pi) + |\omega| C_2 \cos(|\omega|\pi) = 0[/tex]
With [tex]C_1=0[/tex], the second condition reduces to
[tex]|\omega| C_2 \cos(|\omega|\pi) = 0[/tex]
Assuming [tex]C_2\neq0[/tex] (because we don't want the trivial solution [tex]y=0[/tex]), it follows that
[tex]\cos(|\omega|\pi) = 0 \implies |\omega|\pi = \pm\dfrac\pi2 + 2n\pi \implies |\omega| = 2n\pm\dfrac12[/tex]
where [tex]n[/tex] is an integer. In order to ensure [tex]|\omega|\ge0[/tex], we must have [tex]n\ge1[/tex] if [tex]|\omega|=2n-\frac12[/tex], or [tex]n\ge0[/tex] if [tex]|\omega|=2n+\frac12[/tex].
Find the Equation of the Perpendicular Line
Instructions: Find the equation of the line through point (-1, 2) and perpendicular to x + 3y = 3.
y =
Answer:
y = 3x +5
Step-by-step explanation:
The equation of a perpendicular line can be formed by swapping the x- and y-coefficients, and negating one of them. The constant in the equation will be chosen to make the equation true at the given point.
Coefficients swappedThe desired equation in the given standard form will be ...
3x -y = c . . . . . . for some new constant c
Note that we have kept the x-coefficient positive, and have negated the y-coefficient.
Constant valueThe new constant will make the equation true at the point (-1, 2):
3(-1) -(2) = c = -5
So, the standard-form equation is ...
3x -y = -5
Slope-intercept formThe answer form suggests you want to solve this for y. Adding y+5 to both sides will give the form you want:
3x -y +(y+5) = -5 +(y+5)
3x +5 = y
y = 3x +5
