5x6 = 30
30x2 = 60
rectangle in the middle: 15in^2
5x3 = 15
altogether area: 75 in^2

Emilio's Publishing prints and sells cookbooks to stores for $4.50 each. Their weekly profits can be modeled by the quadratic function P(x) = −0.1x2 + 15x + 120, where P(x) is profit and x is the number of $0.05 price increases. Use the graph to answer the question.
Graph of function p of x equals negative 0.1 x squared plus 15 x plus 120. The graph has the x-axis labeled as number of price increases, and the y-axis labeled as profit. The curve begins at (0, 120), increases to (75, 682.5), and decreases through (157.614, 0).
Approximately what amount should the company sell each cookbook for to maximize profit? (1 point)
$8.25
$9.50
$10.20
$17.00
Using the vertex of the quadratic equation, it is found that the profit will be maximized when each cookbook is sold for $8.25.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, the function is modeled as follows, considering x as the price divided by $0.05.
P(x) = -0.1x² + 15x + 120.
The coefficients are a = -0.1 < 0, b = 15, c = 120, hence the x-value of the vertex is given by:
[tex]x_v = -\frac{15}{2(-0.1)} = \frac{15}{0.2} = 75[/tex]
75 increases of $0.05, hence the price will be of:
4.5 + 75 x 0.05 = $8.25.
Hence, the profit will be maximized when each cookbook is sold for $8.25.

The radius, R, of a sphere, is 6.3cm. Calculate the sphere's volume, V.
Use the value 3.14 for, and round your answer to the nearest tenth. (Do not round any intermediate computations.)
Answer:
V = 1046.9
Step-by-step explanation:
The equation for volume is (4/3)pi r^3
substitute 3.14 in for pi and 6.3 in for r so (4/3)*3.14*6.3^3

A regular octagon has an apothem of approximately 4.0 cm and a perimeter of approximately 26.4 cm. Find the area of the octagon.
Answer:
[tex]52.8cm^{2}[/tex]
Step-by-step explanation:
Perimeter = 26.4 cm
Apothem = 4.0 cm
The area of an regular octagon can be defined as the [tex]\frac{perimeter*apothem}{2}[/tex]
when we plug in our values we get the equation [tex]\frac{26.4cm*4.0cm}{2}=52.8cm^{2}[/tex]
What is the value of x in the equation 2.5(6x - 4) = 10 + 4(1.5 + 0.5 x)?
Answer:
x=2
Step-by-step explanation:
You can simplify the equation with all the x's on one side and the numerical values on the other. After solving, the answer would be x=2
Answer:
x=2
Step-by-step explanation:
Distribute the 2.5 and 4 out
15x - 10 = 10 + 6 +2x
Add the constant variables together
15x - 10 = 16 +2x
Move the x on one side and the constant on the other
13x = 26
Divide both sides to find x
x=2

Answer:
Range of x: [tex]0\leq x < 12[/tex] or [tex]0\leq x\leq 11[/tex]
Largest possible value of [tex]x[/tex] is 19
Mean mark = 11.41 (nearest hundredth)
Step-by-step explanation:
The mode is the number that appears the most, so if the mode is 10, [tex]x[/tex] has to be smaller than 10.
We can say this in two ways:
[tex]0\leq x < 12[/tex] or [tex]0\leq x\leq 11[/tex]
since the number of points and players are positive integers.
The median is the middle value when the values in the data set are placed in order from smallest to largest.
If 10 is the median mark, to find the maximum number of 15s, sum the number of players scoring 5 and 10 points and subtract 1:
8 + 11 = 19
Therefore, the largest possible value of [tex]x[/tex] is 19.
The mean is the total of the numbers divided by how many numbers there are.
To find the total marks, multiply the number of points by the number of players, and sum (using x = 19):
[tex]\textsf{Total points}=5 \times 8+10\times12+15 \times 19=445[/tex]
Total number of players = 8 + 12 + 19 = 39
[tex]\textsf{mean mark}=\dfrac{445}{39}=11.41\:\textsf{(nearest hundredth)}[/tex]

Each face of a cube has an area of 4 square units. What is the volume of the cube?
Each face of a cube has an area of 4 square units, then the volume of the cube is 8 cubic units.
The given information states that each face of the cube has an area of 4 square units.
Since a cube has 6 faces, this means that the total surface area of the cube is:
Total Surface Area = 6 * 4 square units = 24 square units
Now, let's relate the surface area of the cube to its volume:
For a cube, the surface area (S) and the volume (V) are related by the formula:
S = 6s²
Where "s" is the length of each side of the cube. In this case, we have:
S = 24 square units
Substitute this into the formula:
24 = 6s²
Now, solve for "s":
s² = 24 / 6
s² = 4
Take the square root of both sides:
s = √4
s = 2
So, each side of the cube is 2 units long.
Now, to find the volume of the cube, you can use the formula for the volume of a cube:
V = s³
Substitute the value of "s":
V = 2³
V = 8 cubic units
Therefore, the volume of the cube is 8 cubic units.

there are 3 numbers in ascending order such that the difference of first two is 10 and that of last two is 12. if the sum of three numbers is 47, find the least number.
Answer:
17/3
Step-by-step explanation:
x + y + z = 47
y - x = 10 x = y - 10
z - y = 10 z = 10 + y
y-10 + y + 10 + y = 47
3 y = 47
y = 47/3 x = 17/3 z = 77/3

Step-by-step explanation:
Does 5, 7, and 9 make a right angle?
No
Step-by-step explanation:
For a triangle to have a right angle the square sums of the legs have to equal the square of the hypotenuse.
In this case 9 is the hypotenuse which is the longest side in a triangle. 5 and 7 are the two smaller sides which make them the legs.
Putting this set of numbers into the pythagorean theorem is the way to solve this.
5²+7² should equal 9² if the triangle is a right triangle.
Solve the squares: 25+49=81
This would add up to be 74 and that is not equal to 81, so by this statement we can conclude that 5, 7, and 9 do not make a right triangle.

The endpoints of a diameter of a circle are given. Write the standard equation of the circle.
Answer:
(x-2)^2+(y-1)^2 = 10^2
(x-2)^2+(y-1)^2 = 100
Step-by-step explanation:
distance between points is diameter
x^2= (8--4)^2+(-7-9)^2
x^2=12^2+16^2
x^2=144+256
x^2=400
diameter x=20 so radius =10
center point =midpoint (-4+8)/2 and (-7+9)/2
center point =(2,1)
(x-2)^2+(y-1)^2 = 10^2
(x-2)^2+(y-1)^2 = 100

What percent of the 8th graders estimated they spend more than an hour a day on social media? Round your answer to the nearest whole number percent.
43
so sorry if this is incorrect.
The percentage of 8th graders estimated they spend more than an hour a day on social media is 43%.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
A survey asked random sample of students if they estimated they spent more or less than an hour a day on social media.
more less
7th 12 14
8th 20 26
To determine the percentage of 8th graders who estimated they spend more than an hour a day on social media, we need to divide the number of students who answered "more" by the total number of 8th-grade students surveyed and then multiply by 100 to get the percentage.
20 students out of 46 students (20+26) answered "more" which is about 43.48%
Thus, the percentage of 8th graders estimated they spend more than an hour a day on social media is 43%.
