What is the cross section created when a slice is made perpendicular to the 2 bases of a cylinder?A.a circle

B.an ellipse

C.a rectangle

D.a triangle

Answers

Answer 1
Answer: The answer would be C. A cross section is defined is the intersection of a plane in a three-dimensional space. Therefore, cutting a cross section perpendicular to a cylinder would result to a rectangle where the height is equal to the height of the cylinder and its width is same as the diameter of the cylinder base.

9x-7=-7 can you help

Answers

Answer:

x=0

Step-by-step explanation:

9x-7=-7

Add 7 to each side

9x-7+7=-7+7

9x = 0

Divide each side by 9

9x/9 = 0/9

x = 0
9x - 7 = -7
(Add 7 to the other side)
9x = -7 + 7
9x = 0
=> x = 0

(You can substitute x back to check for the answer)
9(0) - 7 = -7
0 - 7 = -7

Six times the sum of a number and twelve is forty. Which equation represents this?


6N + 12N = 40
6N + 12 = 40
6(N + 12) = 40

Answers

Depends if number twelve is multiplied by six as well. In other words, it depends if the text means:
six times the sum of (a number and twelve) or six times the sum of a number and than plus 12 equal 40.

In first case answer is:
6(N + 12) = 40 and in second
in second:
6N + 12 = 40
The last one
6(N+12)= 40
