Decide whether each table could represent a proportional relationship. In the essay box explain if the relationship could be proportional, what would be the constant of proportionality?
Annie’s Attic is giving away $5 off coupons.
Answers
Answer:
This table does represent a proportional relationship because the sale price and original price are going up at the constant rate of 10
Step-by-step explanation:
The equation of line is y = -x + 25 and the constant of proportionality is 5
What exactly is a line equation?A line's equation is written as y = mx + b, where m is the slope and b is the y-intercept.
Furthermore, y - y1 = m (x - x1).
y = second point's y-coordinate
y1 = point one's y-coordinate m = slope x = point two's x-coordinate
x1 = point one's x-coordinate
The slope is m = (y2 - y1) / (x2 - x1).
Given the data,
Let the line equation be written as A.
The value of A is now
Let P be the initial point ( 15 , 10 )
Let's call the second point Q. ( 25 , 20 )
The slope of the line is now m = (y2 - y1) / (x2 - x1).
m slope = [tex]\frac{(20-10)}{(25-15)}[/tex]
m slope = [tex]\frac{-10}{10}[/tex]
m slope = -1
The equation for the line is now y - y1 = m (x - x1).
y - 10 = -1 ( x - 15 )
Simplifying the equation yields y - 10 = -x + 15.
We get y = -x + 25 by adding 10 to both sides of the equation.
So, if the selling price x is $10, the original price y is $ 15.
Hence , the equation of line is y = -x + 25 and the constant of proportionality is 5

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of information. An equation relating packets to bytes of information is given by b=1,500p where p represents the number of packets and b represents the number of bytes of information.
1. How many packets would be needed to transmit 30,000 bytes of information?
2. How much information could be transmitted in 30,000 packets?
3. Each byte contains 8 bits of information. Write an equation to represent the relationship between the number of packets and the number of bits.
Answers
Answer:
45,000,000 information could be transmitted in 30,000 packets
Explaination:
b=1500p
p= 30,000
so,
b= 1500 x 30000 = 45,000,000
Answer:
1- 20 packets for this one you have to divide 30,000 by 1,500
2- 45,000,000 bytes for this one you have to multiply 1,500 by 30,000
3- so if each byte is 8 bits of information and 1,500 bytes equal one packet than each packet equals 187.5 bits of information and if you have 30,000 packets than there will be 3,750 bits of information the equation is the number of bytes in a packet divided by the number of bits of information in a byte which is 1,500/8 = 187.5 and the amount of packets you have you divide it by 8 because it is the number of packets divided by the number of bits of information

Step-by-step explanation:
we know that 10yd is the diameter of the unshaded circle. so we will use this to find out the area of the circle. if a diameter of a circle is 10yd, the area is about 78.54 (considering that pi=3.14) to find the area of the shaded region, we can pretend that the entire square is shaded, and then take the unshaded away. if the square was completley shaded, the answer would be 100. but there is a circle inside of the square unshaded, with a area of 78.54, so we need to solve for 100-78.54. this results in our final answer, 21.46

The rectangle and the trapezoid have the same area. What is the length l of the rectangle?
l=
ft
Answers
The length 'l' of the rectangle will be;
⇒ l = 18 feet
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;
The rectangle and the trapezoid have the same area.
Now,
Since, The rectangle and the trapezoid have the same area.
Hence, We get;
Area of rectangle = l × 9
And, Area of trapezoid = 1/2 (24 + 12 ) × 9
= 1/2 × 36 × 9
= 18 × 9
= 162
So, We get;
⇒ l × 9 = 162
⇒ l = 162/9
⇒ l = 18 feet
Thus, The length 'l' of the rectangle will be;
⇒ l = 18 feet
