Answer:
10.5 denarii
Step-by-step explanation:
Step 1: Initially Doubled his money in Lucca and spent 12 denarii
Let's assume the initial money he had before he did anything with it is x,
meaning if he doubled it in Lucca he would have (2×x)=2x, he then spent 12 denarii meaning he was left with (2x-12) denarii.
Step 2: In Florence he doubled what was left on leaving Lucca and spent 12
This is expressed as 2(2x-12)-12=4x-24-12=4x-36
(4x-36) denarii is what remained after he left Florence to Pisa
Step 3: In Pisa he doubled what was left on leaving Florence and spent 12 denarii
This is expressed as 2(4x-36)-12=8x-72-12=8x-84
Step 4: After getting back home in Pisa he was left with nothing
This is expressed as; 8x-84=0, 8x=84
solving for x by dividing both sides of the equation by 8
8x/8=84/8
x=10.5 denarii
Answer:
NO
Step-by-step explanation:
This is because the sample should ideally be representative of the whole population. If the right sampling methods are used, the sample should well exhibit the properties of the whole population. The sample mean should be as precise as possible to the population mean , hence it is not unusual for the sampling to mean to be exactly the same as the population mean
From the details in the dimensions we can infer that the can is a cylinder.
To find the surface area of a cylinder, use the following equation:
Surface area = 2πrh+2πr^2
This basically means (2 times pi times radius times height) plus (2 times pi times (radius to the power of 2)).
First, you need to find the radius.
Radius is equal to half the diameter, so in this case, the radius equals 4.5
Filling in the equation:
2π(4.5)(16)+2π(4.5)^2
Solving the equation:
2π = ~6.28
6.28•4.5 = 28.26
28.26•16 = 452.16
Following order of operations, you must first solve the exponents.
4.5^2 = 20.25
6.28 (which is 2π)•20.25 = 127.17
Now just add!
452.16 + 127.17 = 579.33
So the surface area of the juice can is 579.33 cubic centimeters.
Now for the volume!
Formula to find volume of a cylinder:
πr^2h
Fill in the formula:
3.14(4.5^2)(16)
Solve:
4.5^2 = 20.25
3.14•20.25 = 63.585
63.585•16 = 1017.36
That means the volume of the juice can is 1017.36 cubic centimeters.
So the final answer is:
The surface area of the juice can is 579.33 cubic centimeters and the volume is 1017.36 cubic centimeters.
This is the format of the straight-line equation,
Where, y = mx + c
Here, m = slope
c = y-intercept.
You usually get coordinates, and after solving, we get our result as an equation of the line.
Hope this helps!
