You are selling candy bars for
$2.50 each. The cost of those
candy bars was $1.25 plus a setup
fee of $200 for manufacturing.
1) what is the profit from selling 220 candy bars?
Answer: 75 dollars
Step-by-step explanation:
220 times 2.5 is 550 which means you make 550 dollars. However, it cost 4575 dollars to make the candy bars because 220 times 1.25 is 275 and 275+200 is 475. You have to subtract 475 from 550 to get your answer which is 75 dollars.
Answer:
$75
Step-by-step explanation:
multiply total bars by cost 275+ 200=475
multiply total bars by sale price =550

Find the vertex of the parabola y = 2x2 + 10x + 8
Answer:
The vertex is -5/2 and -9/2
Step-by-step explanation:
I looked it up on math
way
A parabola is a mirror-symmetrical planar curve that is nearly U-shaped. The vertex of the parabola y = 2x² + 10x + 8 is (-2.5, -4.5).
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
Then its roots are given as:
[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
A parabola is a mirror-symmetrical planar curve that is nearly U-shaped.
y = a(x-h)² + k
where,
(h, k) are the coordinates of the vertex of the parabola in the form (x, y);
a defines how narrower the parabola is, and the "-" or "+" that the parabola will open up or down.
The general form of a parabola is written in the form ax²+bx+c, which is a quadratic equation. While the vertex form of the parabola is written as y=a(x-h)² + k.
Given that the equation of the parabola is y = 2x² + 10x + 8. Now if we compare the general equation of the parabola with ax²+bx+c, the value of a, b, and c will be 2, 10, and 8, respectively.
Further, the vertex of the parabola can be written as,
h =−b/2a
h = -10 / 2(2)
h = -10/4
h = -2.5
k = -(b² - 4ac) / 4a
k = -[10² - 4(2)(8)] / 4(2)
k = (100 - 64) / 8
k = -36/8
k = -4.5
Hence, the vertex of the parabola y = 2x² + 10x + 8 is (-2.5, -4.5).

A geometric figure is dilated by a scale factor of 1.5 with the origin as the center of dilation. Which of the following sentences best describes this dilation?
The x- and y-coordinates of every point of the figure is multiplied by 1.5.
Not here.
The y-coordinate of every point of the figure is multiplied by 1.5.
The x-coordinate of every point of the figure is multiplied by 1.5.
Answer:
Step-by-step explanation:
The x and y points are multiplied by 1.5
See the graph
Notice that if you start with (4,6) and dilate by a scale of 1.5 then the final point is (6,9)
The slope of these two points (if they were on a line should be 1.5
x2 = 6
x1 = 4
y2 = 9
y1 = 6
m = (9 - 6)/(6 - 4)
m = 3 / 2
m = 1.5 which is what it should be.
The x-coordinate of every point of the figure is multiplied by 1.5.
The scale factor is 1.5, and the center of dilation is the origin (0, 0).
When the figure is dilated by a scale factor of 1.5 with the origin as the center, it means that each point's x-coordinate and y-coordinate are separately multiplied by 1.5.
The y-coordinate of every point of the figure is multiplied by 1.5 is not correct the reason is that in this specific dilation scenario, only the x-coordinate is multiplied by 1.5, while the y-coordinate remains the same. The origin as the center of dilation means that the points move away from or towards the origin, maintaining the same vertical distance.
Therefore, the correct description is "The x-coordinate of every point of the figure is multiplied by 1.5."

Find the volume of the cone. Use 3.14 for pi.
Answer:
V=37.68
Step-by-step explanation:
The formula for the volume of a cone is V=1/3πr^2h. First, plug the values in to the varibles to get V=1/3π3^2(4), since 3 is the radius and 4 is the height. Now simplify the equation.
V=1/3π3^2(4)
V=1/3π9(4)
V=1/3π36
Multiply 36 by pi, which the equation wants you to use as 3.14.
V=1/3(113.04)
Now simplify to get V=37.68.

Pairs of shoes are manufactured for $24. They are sold to a warehouse with a mark-up of 15%. The warehouse sells the shoes to a distributor after charging a holding fee of $10 per pair. The distributor sells them to ‘Fine Shoes’ for a percentage profit of 12%. The store then marks them up by 30%.
a. Determine the price of a pair of shoes if you buy it from one of the ‘Fine Shoes’ stores (round to the nearest 5 cents). Show working out.
Answer: $54.75
Step-by-step explanation:
The price the shoes are sold to the warehouse is:
= 24 * ( 1 + 15%)
= 24 * 1.15
= $27.60
The price the warehouse sells it is:
= 27.60 + 10
= $37.60
Price distributor sells is:
= 37.60 * 1.12
= $42.112
Fine shoes will then sell at 30% profit:
= 42.112 * 1.3
= $54.7456
= $54.75
Work out the size of obtuse angle DOF, giving a reason for your answer.
Answer:
104
This is because angle at the center is twice the angle at the circumference
Step-by-step explanation:
104 is the size of obtuse angle DOF because the angle at the center is twice the angle at the circumference.
What is an obtuse angle?An obtuse angle is any angle greater than 90 °: Straight angle is a measurement angle equal to 180 °: Zero angles is a measurement angle equal to 0 °: Complementary angle is the angle at which the sum of the measurements is 90 °: Complementary angles are the following angles: The total dimensions are 180 °.
Now we know that angles below 180 degrees and above 90 degrees are obtuse. Examples of bluntness include 110 °, 135 °, 150 °, 179 °, 91 °. Therefore, all angles in the range of 90 ° to 180 ° are obtuse.
