Answer:
Amount charged for downloading individual songs = x dollars
Amount charged for downloading an entire album = y dollars
In respect to person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
In respect to person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second, we get
4x + 3(12.96 - 3x) = 33.93
4x + 38.88 - 9x = 33.93
- 5x = - 4.95
x = 0.99 dollars
Putting the value of x in the first equation, we get
y = 12.96 - 3x
= 12.96 - 2.97
= 9.99 dollars
Below is a scale drawing of a deck for a house What are the length and width, in yards, of the deck represented by the scale drawing?
What is the area, in square yards, of the deck represented by the scale drawing?
Please help me hurry
Answer:
The length of the house is 32 yards and the width is 16 yards and the area of the deck is 512 yards. I got my answer by multiplying the length and the width to get an answer of 512.
Step-by-step explanation:
You have to multiply 16 centimeters by 2 and multiply 8*2. Which is 32 and 16 and after you do that you multiply them 32*16=512

Ricki took a survey in the fifth grade and found that 2/3 of the students ride the bus to school, and 1/4 of the students walk. What fraction of the fifth-grade students either ride the bus or walk to school?
Answer:
11/12 of the 5th grade ride the bus or walk to school.
Step-by-step explanation:
First you have to find a LCD (least common denominator) for both fractions which is 12.
Second you have to multiply the numerator by whatever you multiplied the denominator by for both fractions
Finally you add both fractions together and you get 11/12

The distance a boy travels while hiking is a function of how fast he hikes and how long he hikes at this rate. The boy usually maintains a speed of miles per hour while hiking. Let t represent the input variable. Let h represent the function, and h(t)t the output variable. Evaluate and write a sentence describing its meaning. Write the result as an ordered pair.
Answer:
The distance you travel while hiking is a function of how fast you hike and how long you hike at this rate. You usually maintain a speed of three miles per hour while hiking.
Answer:
h(t)=3t
,where h(t) represents the distance we travel while hiking in time t which is the dependent variable.
Step-by-step explanation:
The distance we travel while hiking is a function of how fast we hike and how long we hike at this rate.
The maintained speed while hiking= 3 miles per hour
If t represent the time of hiking which is independent variable, and h(t) represents the distance we travel while hiking which is dependent variable.
Then, h(t)=3th(t)=3t

John states that the product of two real numbers is a real number. Extending this to imaginary numbers John states that the product of two imaginary numbers must be imaginary. Is his statement correct?

no because these "imaginary numbers" can have the same value as 2 real numbers that add up to a real number. Example:7 3+4=7 x+y (Algebra so not real numbers)= infinite possibilities

Judy began her proof of the converse of the Pythagorean theorem by drawing triangle ABC with side lengths in inches of 5, 12, and 13. She then showed that 5^2 + 12^2=13^2 as follows.
5^2+12^2=13^2
25+144=169
169=169
Next, she drew triangle DEF, with two of the sides forming a 90° angle. If she has done her proof correctly so far, which of these is a length of one of the sides forming the 90° angle? Select two that apply.
A.3 in
B.4 in
C.5 in
D.12 in
E.13 in
Answer:
5 and 12
Step-by-step explanation:
If Judy has done her proof correctly, then the length of one of the sides forming the 90° angle is, 5. So Option C is one of the correct option.
What is Pythagoras theorem?It is the most important theorem of mathematics, which tells us the relationship between sides of the right angle triangle, which are known as Base(A), Height(B), Hypotenuse(H).
Pythagoras theorem,
H² = A² + B²
Given that,
Judy began her proof of the converse of the Pythagorean theorem
The triangle ABC with side lengths in inches of 5, 12, and 13
She showed that 5² + 12² = 13²
Now, In triangle DEF
One of the side length = ?
Suppose, the unknown side length = x
Let, two sides which having length,
base = 3 in.
height = 4 in.
Now, by using Pythagoras theorem
It can be written as,
H² = A² + B²
x² = 3² + 4²
Hence, the third unknown side is of 5 in.

Answer:
Use the Pythagorean theorem: (5/8)^2 +(3/2)^2 = (13/8)^2 ⇒ right triangle
Step-by-step explanation:
Check to see if the numbers satisfy the Pythagorean theorem.
(5/8)^2 + (3/2)^2 = (13/8)^2
25/64 + 9/4 = 169/64
25/65 +144/64 = 169/64 . . . . . . . true. The triangle is a right triangle.
__
If a, b, c represent the lengths of the sides, least to greatest, then ...
a^2 + b^2 > c^2 . . . . acute triangle
a^2 + b^2 = c^2 . . . . right triangle
a^2 + b^2 < c^2 . . . . obtuse triangle

Additional comment
A triple of integers that satisfy the Pythagorean theorem (form a right triangle) is called a "Pythagorean triple." One you see often, and that has the special property that it is the only triple that is an arithmetic sequence is (3, 4, 5). A couple of other common ones are (5, 12, 13) and (7, 24, 25).
Any of these can be scaled by a common factor to make sides of a right triangle. Here, we have (5, 12, 13) scaled by a factor of 1/8 to make (5/8, 12/8, 13/8) = (5/8, 3/2, 13/8) — the numbers in the problem statement.
If you're aware of these common triples, you can check to see if they are being used in any right-triangle problem you may run across. Recognizing that one of these applies can save you the effort of working out the squares and/or root that would otherwise be involved.

Use the function f(x) to answer the questions:
f(x) = 2x2 − 5x + 3
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or a minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answer:
Step-by-step explanation:
Part A)
For equation f(x) = 2x² - 5x + 3, to find x intercepts let y=0 then solve x,
2x² - 5x + 3 = 0 -> (2x + 1)(x -3) = 0 , can find x - intercepts from here
x = ____ and ____
Part B)
To find if vertex is a max or min, compare to equation y = ax² + bx +c
if a > 0 then parabola opens up and vertex is a minimum.
if a < 0 then parabola opens down and vertex is a maximum,
thus vertex is a minimum in this problem
to solve vertex set x = -b / 2a = 5 / 2(2) = 5/4
solve for y value
.... vertex is then at point ( 5/4 , y value found)
Part C)
Can plot the intercepts and vertex points

What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
In a rectangular prism,
Length (l) = 14
Width (w) = 12
Height (h) = 7
We know that;
The surface area of a rectangular prism is given by:
SA = 2 (lh +wh + lw ) Square units.
Hence, We get;
SA = 2 (14 x 7 + 12 x 7 + 14 x 12
SA = 2 (98 + 84 + 168)
SA = 2 x 350
SA = 700 units²
Thus, The value of the surface area of the rectangular prism is,
SA = 700 units²

Write your answer as a decimal rounded to the nearest thousandth.
Answer:
x = 1.55
y = 1.86
Step-by-step explanation:
Determinant of the original matrices;
Do = -3(4) -9(6)
Do = -12 - 54
Do = -66
For Dx
Replace the answer in the first column and fine the determinant
Dy = 17(-3) - 8(9)
Dy = -51-72
Dy = -123
y = Dy/Do
y = -123/-66
y = 1.86
Get Dx
Dx = 4 (-8) - 17(6)
Dx = -32-102
Dx = -134
x = Dx/Do
x = -132/-66
x = 1.55
