To calculate the rate per pound for $33.00 worth of meat at 11 pounds, divide the total cost by the total weight, giving a rate of $3.00 per pound.
Explanation:The question is asking to calculate the rate per pound for $33.00 worth of meat when 11 pounds of meat are bought. To find the rate, we divide the total cost by the total weight in pounds. The rate is the cost of one pound of meat.
Here's the step-by-step calculation:
Determine the total cost of the meat: $33.00.Determine the total weight of the meat: 11 pounds.Divide the total cost by the total weight to find the rate per pound: $33.00 ÷ 11 pounds = $3.00 per pound.Therefore, the rate for $33.00 for 11 pounds of meat is $3.00 per pound.
A landscape architect wishes to enclose a rectangular garden on one side by a brick wall costing $24 per foot and on the other three sides by a metal fence costing $8 per foot. If the area of the garden is 800 ft, find the dimensions of the garden minimizing the cost. (Let x be the length of the brick wall and y be the length of an adjacent side in feet.)
Answer:
x = 20 feet, y = 40 feet
Step-by-step explanation:
See attached photo for solution
The length of the brick wall is 20 ft and the length of an adjacent side is 40 ft and this can be determined by forming the linear equation in two variables.
Given :
A brick wall costs $24 per foot and on the other three sides by a metal fence costs $8 per foot.The area of the garden is 800 [tex]\rm ft^2[/tex].Let 'x' be the length of the brick wall and 'y' be the length of an adjacent side in feet. Then the area of the garden is:
xy = 800 --- (1)
The perimeter of the rectangular garden will be:
Perimeter = 24x + 8x +2(8)y ---- (2)
Now, solve equation (1) for y.
[tex]y = \dfrac{800}{x}[/tex] --- (3)
Now, put the value of 'y' in equation (2).
[tex]\rm P=32x+16\times \dfrac{800}{x}[/tex]
Now, for minimizing cost differentiate the perimeter with respect to 'x'.
[tex]\rm P'=32-16\times \dfrac{800}{x^2}[/tex]
Now, equate the above equation to zero.
[tex]0=32-16\times \dfrac{800}{x^2}[/tex]
[tex]\dfrac{800}{2}={x^2}[/tex]
x = 20
Now, put the value of 'x' in the equation (3).
[tex]y = \dfrac{800}{20}[/tex]
y = 40

what are the new coordinates of the figure aboge if it is reflected over the y axis?
The new coordinates of the figure is :
A=( 1,5) B= (-4,5) C= (-4,8)
Transformations on a Plane:A point on a plane can be subject to transformations. Examples of transformations that can be done on points are translations, reflections, or rotations about a point. These transformations are also observed algebraically, in which functions on the coordinates are applied.
Recall that if (x, y) is a point on the plane, reflecting it across the y-axis means that the x-coordinate is negated:
(x, y) => (-x, y)
The coordinates of the figure is
A = (-1,5)
B = (4, 5)
C = (4, 8)
The new coordinates of the figure is :
A=( 1,5) B= (-4,5) C= (-4,8)
This means that the first coordinate is changed, and the y-coordinate is left as is.
Therefore, it is the y-coordinate that stays the same when reflected across the y-axis.

A (1, 5), B (-4, 5), C (-4, 8) are the new coordinates of the figure aboge if it is reflected over the y axis.
In the realm of plane geometry, various transformations can be applied to points, facilitating a means of altering their positions or orientations. These transformations include translations, reflections, and rotations, all of which have algebraic representations.
When reflecting a point across the y-axis, as denoted by the transformation (x, y) => (-x, y), the x-coordinate is negated while the y-coordinate remains unaffected.
This can be observed in the coordinates of the figure:
A (-1, 5)
B (4, 5)
C (4, 8)
After the reflection, the new coordinates become:
A (1, 5)
B (-4, 5)
C (-4, 8)
It is evident that the reflection operation results in the change of the sign of the x-coordinate while leaving the y-coordinate unaltered. Consequently, the y-coordinate remains the same when a point is reflected across the y-axis, illustrating a fundamental property of this geometric transformation.

Step-by-step explanation:
Volume of Cone formula is given by : [tex]V=\frac{1}{3}\pi r^2 h[/tex]
Given V = 56.52 and h = 7, we plug them in and solve for r:
[tex]V=\frac{1}{3}\pi r^2 h\\56.52=\frac{1}{3}(3.14) r^2 (7)\\56.52=7.33r^2\\\frac{56.52}{7.33}=r^2\\7.71=r^2\\r=\sqrt{7.71}\\ r=2.77[/tex]

The value of x is ????? degrees, and the value of y is ??????? degrees.
The value of X is 112° and The value of Y is 68°
Answer:
Angle y: 68°
Angle x: 112°
Step-by-step explanation:
When you are dealing with two sets of parallel lines where one set intercepts the other, angles are always the same as the parallel line's angle. In this example
∡PM = 68° = ∡y°
Seeing that we now know that y is 68° and q is a straight line (Straight Lines have an angle of 180°) we can subtract 68° from 180° in order to get the degree of the angle x.
180° - 68° = 112°
Now we know that angle y is 68° and angle x is 112°

Does the rule y=-3*2^x represent a linear or an exponential function?
Answer:
its exponential because the parent function is y=(a)(b)^x
Step-by-step explanation:
Final answer:
The rule y = -3 ∙ 2ˣ defines an exponential function due to the term 2ˣ, where the base 2 is a constant raised to the variable power x, leading to a rapid change in y values as x changes.
Explanation:
The rule y = -3 ∙ 2ˣ represents an exponential function, not a linear function. In a linear function, the variable x is raised to the first power and appears in the form y = mx + b, where m and b are constants, and the graph is a straight line. In contrast, an exponential function is of the form y = a ∙ bˣ, where a and b are constants, and b is the base raised to the power of x.
The presence of the term 2ˣ indicates that as x increases, the value of y changes at an exponential rate. This is characterized by a curve that shows a rapid increase or decrease in value rather than a constant rate of change. Additionally, since the base b (which is 2 in this case) is a positive number other than 1, and it is raised to the power of x, this confirms the exponential nature of the function.

Find the value of x°
25°
85°
75°
105°
Answer:
x = 75 degrees
Step-by-step explanation:
155 and the angle next to it makes 180 degrees
To find the missing angle take 180 and subtract 155
180 - 155 = 25
All the angles in the upper triangle are 25, 80 and x
To find x add 80 and 25
80 + 25 = 105
A triangle equals 180 degrees so subtract 105 from 180 to get x
180 - 105 = 75

f(x)=1/x-5, g(x)=5x-1/x A. Use composition to prove whether or not the functions are inverses of each other. B. Express the domain of the compositions using interval notation.
Answer:
Not inverse of each other
Domain : [-∞,0) U (0,5) U (5,∞]
Step-by-step explanation:
Given in the question two functions
f(x)=1/x-5
g(x)=5x-1/x
To find that each of them are inverse of each other we will use composition
f(g(x))[tex]\frac{1}{\frac{5x-1}{x}-5 }[/tex]
take LCM
[tex]\frac{1}{\frac{5x-1-5x}{x}}[/tex]
5x will be cancel
[tex]\frac{1}{\frac{-1}{x}}[/tex]
1 ÷ (-1/x)
1 × (-x/1)
-x
Now,
g(f(x))[tex]\frac{5\frac{1}{x-5} -1}{\frac{1}{x-5}}[/tex]
[tex]\frac{5}{x-5} -1}[/tex] × [tex]5-x[/tex]
[tex]\frac{5-x+5}{x-5} * (x-5)[/tex]
10-x
As it ended up with different answers, so f(x) and g(x) are not inverse of each other
The domain are all the possible x-values of function except x ≠ 0 and x ≠ 5
We can conclude that the domain of the composition function is
Domain : [-∞,0) U (0,5) U (5,∞]
To prove whether or not the functions f(x) = 1/(x-5) and g(x) = (5x-1)/x are inverses of each other, we need to show that their compositions result in the identity function. We also need to find the domain of the compositions f(g(x)) and g(f(x)).
Explanation:To prove whether or not the functions f(x) = 1/(x-5) and g(x) = (5x-1)/x are inverses of each other, we need to show that their compositions result in the identity function. Let's start by finding the composition f(g(x)):
Plug in g(x) into f(x): f(g(x)) = f((5x-1)/x)Simplify f(g(x)) by substituting (5x-1)/x into the expression for f(x)Simplify further to obtain the composition f(g(x)) as a function of xNow, we need to find the composition g(f(x)): g(f(x)) = g(1/(x-5))
Follow the same steps as above to simplify g(f(x)) as a function of x. If the compositions f(g(x)) and g(f(x)) both result in the identity function, then the functions f(x) and g(x) are inverses of each other.
To express the domain of the compositions f(g(x)) and g(f(x)), we need to consider the restrictions on the domains of the individual functions. The domain of f(g(x)) will be the values of x for which (5x-1)/x is defined, and the domain of g(f(x)) will be the values of x for which 1/(x-5) is defined.

The vertex form of the equation of
a parabola is y = 2(x +4)^2 - 7.What is the standard form of the equation?
Answer:
The standard form of the equation is y = 2x^2 + 16x + 25
Step-by-step explanation:
To find the standard form, first square the parenthesis.
y = 2(x + 4)^2 - 7
y = 2(x^2 + -8x + 16) - 7
Now distribute the 2
y = 2(x^2 + 8x + 16) - 7
y = 2x^2 + 16x + 32 - 7
Now combine like terms
y = 2x^2 + 16x + 32 - 7
y = 2x^2 + 16x + 25

Answer:
384 cm²
Step-by-step explanation:
Calculate the volume of metal in the block
V = 16 × 8 × 4 = 512 cm³
Then the volume of the cube = 512 cm³
That is
s³ = 512 ← s is length of side of cube, hence
s = [tex]\sqrt[3]{512}[/tex] = 8 cm
The cube has 6 square faces, hence

Brett kicks a field goal with an initial vertical velocity of 42m/s.how long will it take the football to hit the ground?
Answer:
C
Step-by-step explanation:
You are making a couple of assumptions. The first is that since the given has units of m/s that requires an acceleration based in m/s^2. That eliminates choices A and B. 16 is usually associated with f/s^2
Second, you are assuming 42m/s is positive and the acceleration due to gravity is negative. It doesn't matter as long as they are opposite.
Third, you are assuming that 42 m/s is the vertical acceleration. If it is not then some sort of trigonometry is needed. Since your choices don't offer trig then this assumption must be taken care of.
So the correct answer is C.
True or False. You have to flip the inequality symbol in this problem:
-3x < 15
True
False
You can multiply both sides of an inequality by the same, nonzero number, but if this number is negative, you have to flip the sign.
In this case, in order to solve for x, you have to divide by -3 (i.e. multiply by -1/3), so yes, you must switch the sign:
[tex]-3x<15 \implies x>-5[/tex]
Alternatively, you may add 3x to both sides:
[tex]0<3x+15[/tex]
Subtract 15 from both sides:
[tex]3x>15[/tex]
And divide both sides by 3:
[tex]x>5[/tex]
The sign switch here was hidden behind the fact that we switched the two sides of the inequality
