Julian is 24, Kira is 34. The total of both equals 58.
Answer:
The volume of the pyramid is ![1,260\ cm^{3}](https://tex.z-dn.net/?f=1%2C260%5C%20cm%5E%7B3%7D)
Step-by-step explanation:
we know that
The volume of the triangular pyramid is equal to
![V=\frac{1}{3}BH](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7DBH)
where
B is the area of the triangular base
H is the height of the pyramid
step 1
Find the area of the base B
![B=\frac{1}{2}bh](https://tex.z-dn.net/?f=B%3D%5Cfrac%7B1%7D%7B2%7Dbh)
we have
![b=14\ cm](https://tex.z-dn.net/?f=b%3D14%5C%20cm)
![h=18\ cm](https://tex.z-dn.net/?f=h%3D18%5C%20cm)
substitute
![B=\frac{1}{2}(14)(18)=126\ cm^{2}](https://tex.z-dn.net/?f=B%3D%5Cfrac%7B1%7D%7B2%7D%2814%29%2818%29%3D126%5C%20cm%5E%7B2%7D)
step 2
Find the volume
we have
![B=126\ cm^{2}](https://tex.z-dn.net/?f=B%3D126%5C%20cm%5E%7B2%7D)
![H=30\ cm](https://tex.z-dn.net/?f=H%3D30%5C%20cm)
substitute
![V=\frac{1}{3}BH](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7DBH)
![V=\frac{1}{3}(126)(30)=1,260\ cm^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%28126%29%2830%29%3D1%2C260%5C%20cm%5E%7B3%7D)
Answer:
You will buy 8 jeans and two shirts.
Step-by-step explanation:
set up a systems of equations
identify your variables
jeans = j (a variable means like 'x')
shirts = s
identify a common way to eliminate a variable
(get a common value in both equations so you can add or subtract to leave on variable in which you can solve for)
I think 245 is the answer. I don’t know if you wanted the answer but here it is.
B) 8,000.00 I think that bc he only has 7% on it
