Answer:
39.25 cubic feet of paint will be needed by Ellis.
Step-by-step explanation:
Volume of a cylinder:
The volume of a cylinder of radius r and height h is given by:
How much paint will Ellis need to paint all the surfaces of the 10 fenceposts?
This is the combined volume of these 10 fenceposts.
They are each 5 feet tall and have a diameter of 1 foot.
Radius is half the diameter, so 
. Also 
10 fenceposts:
Each has the same volume, so:
39.25 cubic feet of paint will be needed by Ellis.
Answer:
y - 5 = (-5/6)(x - 2)
y - 5 = (-5/6)x + 10/6
y - 30/6 = (-5/6)x + 10/6
y = (-5/6)x + 20/3
Step-by-step explanation:
How many 6-digit numbers can be formed using the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, if repetitions of digits are allowed?
sveta [45]
There are 6 digits. Each digit can take ten different numbers except for the first digit since it cannot be zero.
So:
9 x 10 x 10 x 10 x 10 x 10
900000 numbers.
Another way of thinking about this is to just count up to 999,999. Obviously there are 999,999 different numbers here. But since our number has to have 6 digits in them, we have to delete 99,999 numbers. Thus there are 900,000 different numbers.
Answer:
2
Step-by-step explanation:
2/3÷1/3
Changing the divide sign into multiply will invert the term after it
So we get
(2/3)*3
(2*3)/3
We get
2
9
230-18.84=211.16
211.16-116.22=94.94
94.94-42.13=52.81
52.81-93.17=-40.36
-40.36-50=-90.36
-90.36-13.12-50=-153.48
-153.48
