Answer:
Procedure in option C only works.
Step-by-step explanation:
We have to select the process in which Mrs. Smith can help her to work 30 divided by 3.
(A) (27 divided by 9) + (9 divided by 3) = 3 + 3 = 6
But (30 ÷ 3) = 10 ≠ 6
(B) (24 divided by 4) + (4 divided by 4) = 6 + 1 = 7 ≠ 10
(C) (21 divided by 3) + (9 divided by 3) = 7 + 3 = 10
(D) (20 divided by 4) + (10 divided by 4) = 5 + 2.5 = 7.5 ≠ 10
So, procedure in option C only works. (Answer)
Again, we can prove the procedure in the following way:
{Which is the distributive property of division}
the earned interest will then be A - P, namely A - 17000.
Answer:
20
Step-by-step explanation:
Assume n is the number of times she pick a skittle out of the bag
The probability she pick out red : 8/n
The probability she pick out yellow : 12/n
=> The ratio of red and yellow skittle : 8/n : 12/n = 8/12 = 2/3, means every 2 red skittles we have 3 yellow ones.
But we have 50 skittles, so the likely numbers of reds in the bag is = 2* = 20
