Prime numbers are: 11, 13, 17, 19, 23
Answer:
First dimension= 12ft Second dimension= 12×2.5=30ft
Step-by-step explanation:
From the question, I was able to deduce that the swimming pool is a cuboid, and the formula for finding the volume of a cuboid is Length×Breadth×Height.
let the first dimension be the length and the second dimension be the breadth.
Therefore, the length=L , Breadth= 2.5×L= 2.5L and Height= 8ft. L×2.5L×8 = 2880 cubic feet.
2.5L²×8= 2880 cubic feet. Therefore, L²= 2880/(2.5×8)=144. L²=144. L=√144. L=12ft. and breadth= 2.5×Length= 2.5×12ft=30ft.
In a nutshell the first dimension is 12ft, and the second is 30ft.
Answer:
0.333n + 28 ; 33.3 ; $41.653
Step-by-step explanation:
For the best fit line :
The slope of the graph :
Drawing a right angled triangle at any point on the best fit line :
Gradient = (y2 - y1) / (x2 - x1)
Gradient = (45 - 30) / (50 - 5)
Gradient = 15 / 45
Gradient = 0.333
Intercept :
Where best fit line crosses the y - axis = 28
b = 0.333n + 28
The extra cost of each extra call made made is the slope of the graph :
$0.333 = 33.3 cents
Estimated cost of 41 calls
b = 0.333(41) + 28
b = $41.653
Kindly note that, the values used were obtained from a graph which isn't lined, therefore values taken may not be very accurate.
<em>At the end of month 11 she will have $911.</em>

Explanation:</h2>
Recall you need to write complete question in order to get exact answers. In this exercise, I'll assume that the complete question is:
<em>Makayla started a saving account. She starts the account with $20 and adds $80 at the end of each month. She will not remove any money from the account. How much money will she have at the end of month 11?</em>
<em />
So, she starts the account with $20, that is, this is a fixed amount of money and at the end of each month she adds 80$. So:
Let:
m: Represents the months.
s: Represents the amount of money that is saved.
We can write an equation:
So, at the beginning of the process so she have:
But at the end of month 11 she will have:
So <em>at the end of month 11 she will have $911.</em>
