Let's say x is the number of ounces. Since the cost for each ounce is $0.85 then we can find the cost for the total amount of ounces by multiplying it by the cost of each one:
$0.85 · x
This is not the total cost, since the total cost has an additional of $5.50. Then the total cost is given by
c = $5.50 + $0.85x
Answer: C: c = 0.85x + 5.50X =x² + 6x + 5 = 0b= ] ± √b22-4aaC
We have the following quadratic equation:
[tex]x^2+6x+5=0[/tex]And we have to use the quadratic equation to solve that equation.
1. To find the solutions, we need to start by using the quadratic equation:
[tex]\begin{gathered} x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} \\ \\ \text{ when }ax^2+bx+c=0 \end{gathered}[/tex]2. Identify a, b, and c from the given quadratic equation:
[tex]\begin{gathered} x^2+6x+5=0 \\ \\ a=1,b=6,c=5 \end{gathered}[/tex]3. Apply the quadratic equation:
[tex]\begin{gathered} x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} \\ \\ x=\frac{-6\pm\sqrt{6^2-4(1)(5)}}{2(1)} \\ \\ \\ \end{gathered}[/tex]4. And now, we can develop it as follows:
[tex]\begin{gathered} x=\frac{-6\pm\sqrt{36-20}}{2} \\ \\ x=\frac{-6\pm\sqrt{16}}{2} \\ \\ x=\frac{-6\pm4}{2} \\ \\ \text{ Therefore:} \\ \\ x=\frac{-6+4}{2}=-\frac{2}{2}=-1 \\ \\ x=-1 \\ \\ x=\frac{-6-4}{2}=\frac{-10}{2}=-5 \\ \\ x=-5 \end{gathered}[/tex]Therefore, we finally have two solutions, x = -1, and x = -5.
Then the first step is given by:

You make an investment of $2250.00 with an absolute change of ―$350.00. What is your investment now
worth and what was the percent change?
1. The investment of $2,250 with an absolute change of -$350 is now worth $1,900.
2. The percentage change in the worth of the investment is -15.56%.
What is a percentage change?A percentage change refers to the percentage difference between the initial value and the current value.
To compute the percentage change, use the absolute change and divide by the initial value, then multiply by 100.
For this investment of $2,250 which is now worth $1,900, there was a percentage change of -15.56%, implying that it has drastically reduced in value.
Initial Investment Cost = $2,250.00
Absolute change in investment value = $350
Current value of investment = $1,900 ($2,250 + $350)
The percentage change = -15.56% (-$350/$2,250 x 100)
Thus, the investment is currently valued at $1,900, having lost $350 in value, which in percentage terms, is -15.56%.

Elijah is lucky enough to get a rent-controlled apartment for $800 per month. The market rent on such an apartment is $3,000 per month. Elijah herself values the apartment at $2,000 per month, and she’d be quite happy with a regular, $2,000 per month apartment. If she stays in the apartment, how much consumer surplus does she enjoy?
The consumer surplus that Elijah will get based on the information is $1200.
What is consumer surplus?It should be noted that consumer surplus simply means the economic measurement of the benefits that the consumer gets from market competition.
From the information, Elijah is lucky enough to get a rent-controlled apartment for $800 per month and the market rent on such an apartment is $3,000 per month.
Since Elijah herself values the apartment at $2,000 per month, the market surplus will be:

The softball team is selling hats. John bought 3 for $24.00. Stacey bought 5 for $40.00. Jim bought 2 for $16.00.
Why does this verbal description represent a proportional relationship?
The value of the hats bought by John, Stacey, and Jim are $8 per hat. This shows a proportional relationship.
What is a proportional relationship?It should be noted that a proportional relationship is one where it van be expressed as y = kx.
In this case, John bought 3 for $24.00. This will be:
= $24 / 3
= $8 per hat
Stacey bought 5 for $40.00. This will be:
= $40 / 5
= $8 per hat
Jim bought 2 for $16.00. This will be:
= $16/2
= $8 per hat

From the given actual height of tower 1083 feet and width 410 feet, the
scale model is equal to 1.98 feet tall.
As given,
Eiffel Tower's actual height = 1083 feet
Eiffel Tower's actual width at base = 410 feet
Scale model's width at base = 0.75 feet
To find: how much tall is the scale model of the Eiffel Tower
Let us assume the height of the scale model of the Eiffel Tower to be x feet
Then by the property of similarity of scale models, ratio of the height of actual Eiffel Tower to its scale model will be equal to the ratio of the width of their base.
=> [tex]\frac{x}{1083} = \frac{0.75}{410}[/tex]
=> x = 1.98 feet
Therefore, the width of the base of the scale model of the Eiffel Tower is 1.98 feet with given actual height and width 1083feet and 410 feet respectively.

What is the role of ethnocentrism in defining the concept of “progress”
Step-by-step explanation:
A linear relationship is shown in the graph.
Which equation best represents the relationship between x and y?
(A) The equation y = ( 1/4 )x + 2 best represents the relationship between x and y.
From the graph, we can see that the line is passing through points ( - 8, 0 ) and ( 0, 2 ).
So, to obtain the equation that represents the best relationship we will substitute the points in the equation to check whether they satisfy or not.
Consider option (a),
y = ( 1/4 )x + 2
For ( - 8, 0) :
0 = ( 1/4 ) × - 8 + 2
0 = - 2 + 2
0 = 0
For ( 0, 2 ):
y = ( 1/4 )x + 2
2 = (1/4) × 0 + 2
2 = 2
Hence, the equation y = ( 1/4 )x + 2 passes through both points.
Consider option (b),
y = 4x - 8
For point ( - 8, 0 )
y = 4(-8) - 8
y = - 32 - 8 = - 40 ≠ 0
For point ( 0, 2)
y = 4(0) - 8 = - 8 ≠ 2
Hence, the equation y = 4x - 8 does not pass through the points.
Consider option (c),
y = ( 1/4 )x - 8
For ( - 8, 0 )
y = ( 1/4 ) × - 8 - 8
y = - 2 - 8 = - 10 ≠ 0
For ( 0, 2)
y = ( 1/4 ) × 0 - 8 = - 8 ≠ 2
Hence, the equation y = ( 1/4 )x - 8 does not pass through points.
Consider option (d),
y = 4x + 2
For point ( - 8, 0 )
y = 4( - 8) + 2
y = - 32 + 2 = - 30 ≠ 0
For point ( 0, 2)
y = 4( 0 ) + 2 = 2
2 = 2
Hence, the equation passes through ( 0, 2) but does not pass through the point ( - 8, 0 ).
Therefore, the equation that represents the relationship between x and y is y = ( 1/4 )x + 2

Find the surface area and volume of the solid. Round each measure to the nearest tenth, if necessary.
The surface area and volume of the given pyramid are 800ft³ and 1280ft³.
What is a pyramid?The following is the general formula to determine the pyramid's surface area and volume: The base area of a pyramid is added to half the product of the base perimeter and slant height to determine its total surface area. The Total Surface Area of the Pyramid is, therefore (1/2)Pl + B square units.So, the formula for the surface area of the Right rectangular pyramid:
[tex]A = lw+l\sqrt{(\frac{w}{2})^{2}+h^{2} } +w\sqrt{(\frac{l}{2} )^{2}+h^{2} }[/tex]Now, l = 16, w = 16 and height = 15 feet.Substitute the values in the formula:(Refer to the image attached below for calculation)
The surface area of the pyramid is 800ft³.

9) length of the tree is 22.165 meter
10 ) the length of the steel beams is 3.7464 meters
9 ) Given: The angle is 55.2 °
The length of the shadow is 15.5 meter.
To find : the length of the tree
The by using the formula tan θ = perpendicular / base
tan θ = length of the tree/ shadow
thus the length of the tree = length of shadow × tan θ
= 15.5 × tan 55.2
= 15. 5 × 1.43
= 22.165 meter
Thus the length of the tree is 22.165 meter
10) the angle of inclination = 42 °
The height of the slab is 5.6 meters
Thus the length of the steel beams is :
sin 42 ° = perpendicular / hypotenuse
hypotenuse = perpendicular × 0.669
hypotenuse = 5.6 × 0.669
= 3.7464 meters
Thus the length of the steel beams is 3.7464 meters.

Prove that,if one root of the equation ax^2+bx+c=0 is twice the other,then 2b^2=9ac
The proof of the quadratic equation is represented by the equation 18(m₂)² = 18(m₂)²
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax² + bx + c or y = a(x - h)² + k
How to prove the roots of the quadratic equation?The quadratic equation is given as
ax² + bx + c = 0
From the question, we understand that
One of the roots is twice the other
This means that
m₁ = 2m₂
Where m₁ and m₂ are the roots of the quadratic equation
The quadratic equation is then represented as
(x - m₁) * (x - m₂) = 0
Substitute m₁ = 2m₂ in the equation (x - x₁) * (x - x₂) = 0
So, we have
(x - 2m₂) * (x - m₂) = 0
Expand the brackets
So, we have
x² - 2xm₂ - xm₂ + 2(m₂)² = 0
Evaluate the sum and the difference.
So, we have
x² - 3xm₂ + 2(m2)² = 0
In the above equation, we have
a = 1
b = -3m2
c = 2(m₂)²
Recall that
2b² = 9ac
So, we have
2 * (-3m₂)² = 9 * 1 * 2(m₂)²
Evaluate
18(m₂)² = 18(m₂)²
The above equation is true
Hence, it is true that if one root of the equation ax² + bx + c = 0 is twice the other, then 2b² = 9ac
