Here you go! I apologize if it makes no sense. I write my notes and practice problems super weirdly.
Answer A: 84π
Answer B: I'm also confused. If anyone else knows can you please help me also. Sorry for not answering B. I hope this helps though.
Step-by-step explanation:
Answer A:
V=1/3π 6^2 (7) Since 12 is a diameter you half it which is 6
V=1/3π 36(7)
V=1/3π 252
V= 252π/3
V=84π
The 3 consecutive numbers are 88, 89, and 90. So 90 is the answer.
Answer:
you need 2,400 tiles
Step-by-step explanation:
400x300=120,000 thats how big the area of the room will be.
120,000÷50=2400
Answer:
The Explanation is below with attachment.
Step-by-step explanation:
For the line y = 2x - 5
For Drawing a line on a graph we require minimum two points, but we will plot three points.
Here you can take any random value for X so that the corresponding Y value you will get.
So, put x = 0, in the equation we will get

Similarly,
Put x = 1 we will get,

Again,
Put x = -1 we will get,

Now we have three points say point A (0,-5)), point B (1.-3) and point C (-1,-7)
See the graph below
