Which of these shapes have rectangular cross sections when they are cut perpendicular to the base? Select three op
rectangular prism
triangular prism
cylinder
cone
square pyramid
triangular pyramid

Option A :   Rectangular prism

Option B: Triangular Prism

Option E : Square Pyramid

Step-by-step explanation:

When these shapes are cut perpendicular to base,the following have  rectangular cross sections:

A. Rectangular Prism→Rectangular prism , has base in the form of rectangle,so when cut perpendicular to base,the base as well as other faces, will be in the shape of Rectangle.

B. Square Pyramid:→Square pyramid has base in the shape of Square,so when cut perpendicular to base,the base  will be similar to Square .

As,Every Square is a Rectangle,so the Square Pyramid when cut perpendicular to base ,the base Resembles with rectangle.

C: Triangular Prism: When triangular prism ,cut perpendicular to base,one of the face will resemble with Rectangle.

Option A :   Rectangular prism

Option B: Triangular Prism

Option E : Square Pyramid

just needed some points but try socratic

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
