Answer: 44%
Step-by-step explanation:
Area of the first hole = 30 × 30 = 900
Area of second hole = (30+6) × (30+6) = 36 × 36 = 1296
Percentage increase = (1296 - 900) / 900 × 100
= (396 / 900) × 100
= 44%
the taxi fare in a city is as follows: for the first kilometre, the fare is rupee 8 and for the subsequent distance it is rupee 5 per km. taking the distance covered as x km and total fare as rupee y, write a linear equation for this information, and draw its graph
Answer:
The linear equation is Y=5x+8 where x>0
(you can input this into the Desmos graphing calculator to see the graph if you like!)
Step-by-step explanation:
To get the answer is fairly straight forward. If we know that distance covered is x in the equation and we know that a linear equation follows the template Y=mX+b where m is slope and b is the y-intercept. The first step is to fill in what we know. That would look as such Y=_X+_. We can then attempt to fill in the blanks for m and b. Because we know that it is 5 rupees extra per subsequent kilometre we can put 5 as the multiplier for x and there is our m or slope. We now have Y=5x+_. Now for b. B in this case is quite simple as is showing us where the start of the graph is. It is stated that there is a flat fee of 8 rupees, so the total can never be less than 8. Because b is simply where the line intercepts the y axis, and we want it to intercept at 8, we can just put a plus 8. And there you have it Y=5x+8. One important note is that the graph when drawn should be a ray extending from point (0,8). This is because we want to eliminate all of the areas on the plane that would make the fare negative, as we could not have a negative cab fare. This is as simple as plotting the line starting from point (0,8) on the y axis. Happy to help!

Based on the scatterplot, which is the best prediction
of the number of gallons of water used by this
business when the cost of water is $180?
Answer:
90,000
Step-by-step explanation:
As per the given scatter plot, for the cost of $180, the number of gallons of water used is 90,000.
The association between two numerical variables measured for the same individuals is displayed in a scatterplot. One variable's values are displayed on the horizontal axis, and the other variable's values are displayed on the vertical axis.
Here,
According to the question, the maximum limit shown on the scatterplot is $180 for 90 units on the scatterplot,
Where horizontal units are represented as the scale of 1 unit = 1000 units.
So for the maximum.
For the cost of $180 the gallons of water used is 90×1000.
Thus, as per the given scatter plot, for the cost of $180, the number of gallons of water used is 90,000.

Answer: The amount of hotdogs you would need to sell in order to reach $300= 80
Step-by-step explanation:
Find how much money is spent per hotdog:140÷70=2
$140= Amount made by selling 70 Hotdogs
70=Amount of Hotdogs sold already
Dividing 140 by 70 will get you the cost of 1 hotdog. This is due to division being the act of separating something into parts. There are 70 parts (or hotdogs) in this equation so therefore by separating the amount of money made by those selling those parts, the amount per hotdog would be found.
2. Find the amount of hotdogs it would take to earn a total of $300:
300-140= 160 160÷2= 80
The question asks for a total of $300 to be earnt by selling hotdogs. $140 has already been earnt, therefore a portion of the total amount has been made. By subtracting the amount already made by the total amount of money that is wanted to be earnt, the amount of money needed to reach the $300 is found. The $160 is then divided by the amount of money spent per hotdog ($2). The answer (80) is the amount of hotdogs required to be sold to reach the goal of $300.

12x -20=n (3x-5)
I need help I don’t get it please help me.
Answer:
The value of n = 4 and
The value of x = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
Method I:
As given, 12x -20=n (3x-5) .........(1)
Firstly , take 12x - 20
As 12x - 20 can be written as 4(3x - 5)
∴ equation (1) becomes
4(3x - 5) = n (3x-5)
Divide the equation by (3x-5) , we get
4 = n
Method II:
As given, 12x -20=n (3x-5)
⇒12x - 20 = 3nx - 5n
⇒12x - 3nx = 20 - 5n
⇒3x(4 - n) = 5( 4 - n)
Divide the equation by (4-n) , we get
3x = 5
⇒ x = [tex]\frac{5}{3}[/tex]
∴ we get
n = 4 and x = [tex]\frac{5}{3}[/tex]
Now, check that value of n and x satisfies the equation or not
12([tex]\frac{5}{3}[/tex]) - 20 = 4( 3([tex]\frac{5}{3}[/tex]) - 5)
⇒4(5) - 20 = 4(5 - 5)
⇒20 - 20 = 4(0)
⇒ 0 = 0
Hence , we get
The values of x and n satisfies the equation
so, we get
n = 4 and x = [tex]\frac{5}{3}[/tex]
