Answer:
3.745 kg
Step-by-step explanation:
Given:
15% of its height each day
27 inches on day 10.
How tall was it yesterday?
27 represents 115% of the height yesterday. So we divided 27 by 115% to get yesterdays height.
27 ÷ 115% = 23.48 inches.
The plant was 23.48 inches tall yesterday.
To check:
23.48 x 15% = 3.52 inches
23.48 + 3.52 = 27 inches
Answer:
9 rows x 6 columns = 54 people.
Step-by-step explanation:
9 rows and 6 columns.
So there must be 9 rows of people, and each row is 6 people deep. (That is how they get the columns! Duh!)
9 x 6 = 54 people
If n is the number of cans in row r
n = 9 - r where r is a natural number less than 9
When r = 5 then n = 9 - 5 = 4
(you could let r = 9 as the ninth row has zero cans but values above 9 will give negative counts)
