Answer: :(
Step-by-step explanation: you said 20
The volume of a figure is the number of cubic units present in the figure. For this problem, we assume that the figure would be a rectangular box in shape. So, the volume would be calculated by the product of its length, width and height or in this case the depth. We calculate the volume of water as follows:
Volume = 4.50 ft x 7.00 ft x 5.00 in ( 1 ft / 12 in )
Volume = 13.125 ft^3
We need to convert the resulting volume in liters. We do as follows:
Volume = 13.125 ft^3 ( 0.3048 m / 1 ft )^3 ( 1000 L / 1 m^3 )
Volume = 371.66 L
Paralel lines have same slope
if green line is paralell to red line
and the slope of the green line is 1/4
slope of red line is 1/4 also
ANSWER
![S_5= 42.5](https://tex.z-dn.net/?f=S_5%3D%2042.5)
EXPLANATION
The general term of the arithmetic sequence is
![a_n=1+\frac{5}{2}n](https://tex.z-dn.net/?f=a_n%3D1%2B%5Cfrac%7B5%7D%7B2%7Dn)
For the first term,we substitute
![n=1](https://tex.z-dn.net/?f=n%3D1)
to get,
![a_1=1+\frac{5}{2}\times 1](https://tex.z-dn.net/?f=a_1%3D1%2B%5Cfrac%7B5%7D%7B2%7D%5Ctimes%201)
![a_1=1+2.5=3.5](https://tex.z-dn.net/?f=a_1%3D1%2B2.5%3D3.5)
Similarly
![a_5=1+\frac{5}{2}\times 5](https://tex.z-dn.net/?f=a_5%3D1%2B%5Cfrac%7B5%7D%7B2%7D%5Ctimes%205)
![a_5=13.5](https://tex.z-dn.net/?f=a_5%3D13.5)
The sum of the first n-terms is given by the formula,
![S_n=\frac{n}{2}(a_1+l)](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%28a_1%2Bl%29)
where l is the last term.
In this case
![l=a_5=13.5](https://tex.z-dn.net/?f=l%3Da_5%3D13.5)
We substitute these values to get,
![S_5= \frac{5}{2} (3.5 + 13.5)](https://tex.z-dn.net/?f=S_5%3D%20%5Cfrac%7B5%7D%7B2%7D%20%283.5%20%2B%2013.5%29)
![S_5= \frac{5}{2} (17)](https://tex.z-dn.net/?f=S_5%3D%20%5Cfrac%7B5%7D%7B2%7D%20%2817%29)
![S_5=42.5](https://tex.z-dn.net/?f=S_5%3D42.5)
We could have also used the formula,
To help you out see how much one yard is then how much a feet is and it should help then multiply.
