Answer:

The height of the pyramid is 50\ in

Step-by-step explanation:

we know that

The volume of a triangular pyramid is equal to

V=\frac{1}{3}BH

where

B is the area of the base

H is the height of the pyramid

we have

V=1,800\ in^{3}

The area of the base B is equal to

B=\frac{1}{2}(12)(18)=108\ in^{2}

substitute and solve for H

1,800=\frac{1}{3}(108)H

5,400=(108)H

H=5,400/(108)=50\ in

Andreyy89

Answer:

Step-by-step explanation:

Branson and his sister Beatrice combined their allowance of $7 each. This means that the total amount they had is 7 + 7 = $14

They bought a movie for $12. The amount that they have left is

14 - 12 = $2

They bought $1 containers of fruit salad with the remaining money and split the containers evenly between them. This means that the number of containers that they bought is

2/1 = 2

If they split the containers evenly between themselves, then each person would get

2/2 = 1 container of fruit salad
