Answer:
The answer is A. The volumes are the same
Step-by-step explanation:
First you have to determine the area of the cross sections for each of them.
The area of the rectangular cross section will be:
A= 7(6)
A= 21 cm²
The area of the triangular cross section will be:
A=
(7)(6)
A= 21 cm²
So, they both share the same area which Cavalieri's Principle said that if two solids of equal height have equal cross-sectional area at every level, then the volume are the same.
Hello from MrBillDoesMath

Answer: Subtract 7 from each term (left to right) to get the next term
For example.
101- 7 = 94
94 - 7 = 87
87 = 7 = 80

Answer:
x = -9, 9.
Step-by-step explanation:
x^2 - 81 = 0
x^2 = 81
x = -9, 9.
We want to find the work done by lifting a book a given distance.
The answer is 200 N*m
We know that the book weighs 100 Newtons and that we lift it a distance of 2 meters.
Remember that the work needed to lift an object of mass M to a height H is:
W = M*g*H
where g is the gravitational acceleration.
Knowing that:
weight = M*g
We can replace the things we know to get the work:
W = 100N*2m = 200 N*m

Answer:
15 degrees
Step-by-step explanation:
x + 5x + 90 =180( sum angle of a triangle )
6x + 90 = 180
6x = 180 - 90
6x = 90
x = 90/6
x = 15 degrees
