ANSWER
EXPLANATION
The volume of the cone is
The height of the is 6 inches.
We put the values into the volume of cone to get.
Divide through by 2π.
The expression on the LHS is a perfect square trinomial.
-- Machine-X takes 3 minutes for 300 boxes . . . 3/300 = 1/100 minute per box.
-- Machine-Y takes 2 minutes for 300 boxes . . . 2/300 = 1/150 minute per box.
-- 3/150 = 2/100 . . . In 3/150 second, they can make 5 boxes by working together.
-- They need to make 5 boxes (300/5) = 60 times.
-- They'll need to work for 60 times (3/150) minutes.
60 (3/150) = 180/150 = 1.2 minutes = <u>1 minute and 12 seconds</u>.
Many inequalitys have -25 in their solution sets.
There are too many to name.
Hello,
f(x)=6x^3+18x²+12x=6x(x²+3x+2)
=6x(x²+x+2x+2)=6x((x(x+1)+2(x+1))
=6x(x+1)(x+2)
Zeros are 0,-1,-2
Answer:
0.722
Step-by-step explanation:
First of all add up the sections 1 to 8 to make sure they add to 360
They do actually.
- 1 10
- 2 20
- 3 30
- 4 40
- 5 50
- 6 60
- 7 70
- <u>8 80</u>
Total 360
This is an area question. Every time you spin the spinner, it must come to an area labeled 1 to 8.
You could do this by setting up a ratio of each section and subtract the section for 3 and 7. That's the long way.
The shorter way is to add up the degrees for 3 and 7 and subtract them from the total (360)
Area 3 + area 7 = 30o + 70o = 100 degrees.
So the probability of landing in 3 or 7 is 100 / 360 = 0.278 (rounded)
The probability of Not landing on 3 or 7 is 1 - 0.278 = 0.722
