Answer:
Sharika needs 2.5 days to finish the remaining work
Step-by-step explanation:
Sharika can do a work in 6 days palkey can do it in 8 days
Then the amount of work sharika can do in 1 day = 1/6
And the amount of work palkey can do in 1 day = 1/8
The amount of work both of them can do together in 1 day = 1/6 + 1/8
= 7/24
The amount of work both of them can do together in 2 day = (2× 7/24)
= 7/12
Since Palkey left the work,the amount of
work remaining for Sharika to do alone = (1 - 7/12 )
= 5/12
The number of days Sharika take to finish the remainig work. = (5/12 ÷ 1/6 )
= 5/2 days
Therefore, Sharika needs 2.5 days to finish the remaining work.
Answer: D (bottom option)
Not Congruent
Step-by-step explanation:
Assuming the trapezoids are to scale, they are not the same shape. This means that they could not be congruent even if they were centered on top of each other.
Multiply the length by the width and your answer will be there.
