What is area of rectangle?
Area of rectangle is the total space taken by the rectangle. If l is the length of the rectangle and b is the breadth of the rectangle, then area of the rectangle is given by
Area = [tex]l \times b[/tex]
Here,
Width of the wall = [tex]15\frac {2}{3}[/tex] feet = [tex]\frac{47}{3}[/tex] feet
Height of the wall = [tex]\frac{3}{4} \times \frac{47}{3}[/tex] feet
= [tex]\frac{47}{4}[/tex] feet
a) Area of the wall = [tex]\frac{47}{3} \times \frac{47}{4}[/tex] [tex]ft^2[/tex]
=[tex]\frac{2209}{12} \times 12 \times 12[/tex] [tex]in^2[/tex]
= [tex]26508[/tex] [tex]in^2[/tex]
b) Length of painting = [tex]40 \frac{1}{2}[/tex] in = [tex]\frac{81}{2}[/tex] in

6. There were a total of 139 points scored in the basketballgame. The Falcons scored (9x+22) and the Mavericks scored(16x - 8). What was the Falcons score for the game?
The total score in the basket game = 139
Falcons score = 9x + 22
Maverick score = 16x - 8
Therefore,
139 = 9x + 22 + 16x - 8
collect like term
139 - 22 + 8 = 9x + 16x
125 = 25x
divide both sides by 25
x = 125/25
x = 5
Falcons score = 9x + 22
Falcons score = 9(5) + 22
Falcons score = 45 + 22
Falcons score = 67

[tex][/tex]A web music store offers two versions of a popular song. The size of the standard version is 2.1 megabytes (MB). The size of the high quality version is 4.7 MB. Yesterday, the high quality version was downloaded twice as often as the standard version. The total size downloaded for the two versions was 3335 MB. How many downloads of the standard version were there?Number of standard version downloads: ?
Answer: 529.3 downloads
Explanation:
Standard version size = 2.1 MB
High quality version = 4.7 MB
The high-quality version was downloaded twice as often as the standard version
H = 2 S
The total size downloaded for the two versions = 3335 MB
H + S = 3335
We have the system:
H = 2 S (a)
H + S = 3335 (b)
Put A into B
(2S ) + S = 3335
3S = 3335
S= 3335/3
S= 1,111.67 MB
Divide the total MB of standard versions by the size of each standard version.
1,111.67 / 2.1 = 529.3 downloads

An observation deck extends 200 feet out above a valley. The deck sits 150 feet above the valley floor. If an object is dropped from the observation deck, its height h in feet, after t seconds, is given by h=-16t^2 +150. How long will it take for the object to be 6 feet above the valley floor?
If equation of the height is h = -16[tex]t^2[/tex]+150, then the time taken for the object to be 6 feet above the valley floor is 4.28 seconds
The equation of the height h = -16[tex]t^2[/tex]+150
Where h is the height
t is the time taken
We have to find the time taken for the object to be 6 feet above the valley floor
The height = -150+6
= -144
Substitute the values in the equation
-16[tex]t^2[/tex]+150 = -144
-16[tex]t^2[/tex] = -144-150
-16[tex]t^2[/tex] = -294
[tex]t^{2}[/tex] = 18.375
t = 4.28 seconds

Determine if the table shows a proportional relationship. x 42.5 29.2 69.4 y 21.25 14.6 34.7 Yes, it is proportional because the ratios for y over x are all equivalent to one half. Yes, it is proportional because the ratios for y over x are all equivalent to one third. No, it is not proportional because 21.25 over 42.5 is not equal to 29.2 over 14.6. No, it is not proportional because 42.5 over 21.25 is not equal to 34.7 over 69.4.
Yes, it is proportional because the graph of these coordinates is a straight line and the ratios for [y] over [x] are all equivalent to one half.
What is proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. A straight line represents a proportional relationship. Mathematically -
y = kx + c
(y - c)/x = k [k is constant]
or
y = kx
k = y/x [k is constant]
Given is the following data -
[x] 42.5 29.2 69.4
[y] 21.25 14.6 34.7
In order to find if the given coordinates represent proportional relationship, plot these coordinates on graph. If the by joining the coordinate points, we get a straight line, then it represents a proportional relationship. Graph is attached with the answer. It can be seen that its graph is a straight line and hence represents a proportional relationship.
Now, the ratio of [y] by [x] -
m = (21.25 - 14.6)/(42.5 - 29.2) = 6.65/13.3 - 0.5 = 1/2
Therefore, we can say that, Yes, it is proportional because the graph of these coordinates is a straight line and the ratios for [y] over [x] are all equivalent to one half.

100 POINTS Which statement about this figure is true?
It has no rotational symmetry.
It has rotational symmetry with an angle of rotation of 90°.
It has reflectional symmetry with four lines of symmetry.
It has point symmetry
before you answer, just know it does have rotational symmetry, just not 90° so A and B are out. i'm just stumped about C and D
Answer:
It has reflectional symmetry with four lines of symmetry.
Step-by-step explanation:
======================================================
Explanation:
Choice A is false since it does have rotational symmetry. See choice B.
Choice B is close, but the "90 degrees" needs to be "45 degrees". Each 45 degree rotation of the figure has the "before" and "after" be the same.
Choice C is one of the answers. There's a vertical line of symmetry, and a horizontal one as well. Then there are two diagonal lines of symmetry. Each goes through the center. A line of symmetry is a mirror line to allow us to reflect one half over this line to get the other half.
Choice D is another answer. It has point symmetry since we can pick any point on the figure and reflect it over the center point, to land on a corresponding image point on the opposite side of the figure. For example, the northern most point reflects over the center to land on the southern most point.
A factory makes light fixtures with right regular hexagonal prisms where the edge of a hexagonal base measures 4 centimeters and the lengths of the prisms vary. It costs $0.04 per square centimeter to fabricate the prisms and the factory owner has set a limit of $11 per prism. What is the maximum length of each prism?
The maximum length of each prism is equal to 7.99 centimeter.
How to calculate the maximum length of each prism?First of all, we would determine the maximum surface area of this regular hexagonal prism by using this mathematical expression:
Maximum surface area (quantity) = Cost/unit price
Maximum surface area (quantity) = $11/$0.04
Maximum surface area (quantity) = 275 square centimeter (cm²).
Mathematically, the surface area of a regular hexagonal prism can be calculated by using this formula:
A = 6al + 3√3a²
Where:
A represents the surface area of a regular hexagonal prism.a represents the edge length (apothem) of a regular hexagonal prism.l represents the length of a regular hexagonal prism.Substituting the given parameters into the formula, we have;
275 = 6 × 4l + (3√3 × 4²)
275 = 24l + 48√3
24l = 275 - 48√3
24l = 191.8616
l = 191.8616/24
