Since an ark is 2.5 cubits in length and 1.5 cubits in width and height.
It is given that a cubit is equivalent to 17.7 in.
We have to determine the volume of the ark in cubic feet.
Since 1 feet = 12 inches.
Since, length = 2.5 cubits
= 
inches
= 44.25 inches
= 
= 3.7 feet
Now, width = 1.5 cubits
= 
inches
= 26.55 inches
= 
= 2.2 feet
Now, height = 1.5 cubits
= inches
= 26.55 inches
=
= 2.2 feet
SO, Volume of rectangular prism = 
So, Volume of ark= 3.7 
= 17.9
= 18 cubic feet.
Therefore, the volume of an ark is 18 cubic feet.
100+8=108
108% of 37.50=1.08 times 37.50=40.5
(40.5-37.50=3, tax was 3)
18% tip
100+18=118
118% of 40.5=1.18 times 40.5=47.79
amount total was $47.79
tax was $3
Answer:x = 1
y = 1
Step-by-step explanation:
The given system of simultaneous equations is expressed as
3x - 5y = - 2 - - - - - - - - - - - - 1
2x + y = 3 - - - - - - - - - - - - - 2
The first step is to decide on which variable to eliminate. Let us eliminate x. Then we would multiply both rows by numbers which would make the coefficients of x to be equal in both rows.
Multiplying equation 1 by 2 and equation 2 by 3, it becomes
6x - 10y = - 4
6x + 3y = 9
Subtracting, it becomes
- 13y = - 13
y = - 13/- 13 = 1
The next step is to substitute y = 1 into any of the equations to determine x.
Substituting y = 1 into equation 2, it becomes
2x + 1 = 3
2x = 3 - 1 = 2
x = 2/2 = 1
