Answer:
21feet = h
The height of the pyramid is 21 feet
Explanation:
Like the volume of any pyramid and any tetrahedron, the volume is the area of the base by the height and divided by three.
a and b are the sides of the base, which is a rectangle, and therefore a*b is the area of the base.
Volume= a*b*h/3
1) The term we need to know is the h which is the height. What we are going to do is to leave alone the h in one side of the equation applying math properties.
3*V= a*b*h
What we did was to bring the 3 to the other side. It was dividing on the right side of the equiation. To go to the other side, it must multiply the term on the left.
2) Now, we need to bring the a*b to the left side. We take the term and pass it dividing the term on the left.
(3*V )/ (a*b) = h
3) Now we can use the equation to find the height.
(3*525f³) / (15f*5f) = h
21f = h
Answer:
The time of oil tanker will be 80 sec.
Explanation:
Given that,
He walks at 3 km/hour.
If the container ship is 100 m long, and travelling at 12 km/hour.
The distance will be 200 m.
We need to calculate the relative velocity
Using formula of relative velocity
Put the value into the formula
The distance is 200 m.
We need to calculate the time
Using formula of time
Put the value into the formula
Hence, The time of oil tanker will be 80 sec.
