Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, prisms.
A prism is a polyhedron, with two parallel faces called bases. The other faces are always parallelograms. The prism is named by the shape of its base.
Here are some types of prisms
Triangular.
Square.
Rectangular.
Pentagonal.
Hexagonal.
Hence in other to solve for the area of any prism we need to know the shape of the prism first
Answer:
f(t)= 17- 50t/21
Step-by-step explanation:
distance covered after t hours= 50t miles
number of gal.=50t×1/21 =50t/21 gal.
f(t)=starting-consuming= remaining
= 17-50t/21
Ignore the last one!! But I hope this helps!! If you need an explanation you can message me!
