You have to put it in your own words
(2,700−1,200)÷30
1500÷30
=50 flower pots
Hope it helps:-)
Since the prefix centi- means 100, 1 gram is equivalent to 100 centigrams. You have to multiply 30 grams by 100 to get the number of centigrams.
30 * 100 = 3000
So, 30 grams is equivalent to 3000 centigrams.
Hope this helps! :)
According to my calculations it should be 77
Answer:
Step-by-step explanation:
Work done= rate *time
let time taken by X to produce w widgets be t days
rate = w/t
Since X take 2 days longer rate for Y would be
rate= w/t-2
combined rate is (w/t+w/t-2)
Since in 3 days both x and y can produce 5w/4
(w/t+w/t-2)= 5w/4
5t2 -34t +24=0
(t-6)(t-4/5)=0
t=6 or t=4/5(not possible because t-2(time taken by Y) comes out to be -6/5 which is not possible)
so t=6 days which is the time taken by X to produce w widgets
so time taken to produce 2w widgets will be 12 days.
