As Tiana can clear the field in 3 hours,
it means she can clear in 1/3 per hour
Also, Jacob can do 1/2 of the work per hour.
now the rate we will determine when they are working together
so
hours are for completing:
Tiana = 3
Jacob = 2
Together = t have to find
so
Work done per hour:
Tiana = 1/3
Jacob = 1/2
Together = 1/t
by adding their work together
it will be
1/3 + 1/2 = 1/t now solve it
5/6 = 1/t
t = 6/2 = 1.2
<span>1.2 hours they can clear the field
hope it helps</span>
Answer:
There should be 40 stones in the bucket
Step-by-step explanation:
4:3 = x:30
3*10 = 30
4*10 = 40
x = 40
Hopefully that helped.
Answer:
C is parallel to D, the second option
Step-by-step explanation:
The angles are the same so c and d will never collide.
X^2+2x= -8
x^2+2x+1= -8+1
(x+1)^2= -8+1
(x+1)^2=-7
x+1= √-7
The answer is No Solution because the root of a negative number is not a real number.
