9x^2 + 6x = 1
Factor out 3x
3x (3x +2)=1
Use the zero product property
3x=1
3x+2 = 1
X= +1/3 and -1/3
Answer:
height of the waste is 20.0 inches.
Step-by-step explanation:
given data
volume = 5, 667.7cubic inches
radius = 9.5 inches
solution
we use here volume of a cylinder is express as
V = πr²h .................1
put here value
5667.7 = (3.14) × (9.5²) × h
solve it we get
h = 20 inch
so height of the waste is 20.0 inches.
Answer:
∠1 = 23°
∠2 = 23°
Step-by-step explanation:
Take out the GCF of 5.
5(5c - 1)
We will express the work done relative to time thus,
person a = 1/4
person b = 1/6
Since two of them will work together and then add the two.
total work = person a + person b
= 1/4+1/6
=(3+2)/12
=5/12 hours
in hours
1/t=5/12 hours
total time = 2.4 hours or 2 hours and 24 mins.
The total time that person a and person b when working together will make the work done in 2.4 hours.
