Answer:
6days
Step-by-step explanation
Let's make an equation from this expression.
From the number of potatoes at the first warehouse after x days is:
y = 210 + 90x .............. 1
From the number of potatoes at the second warehouse after x days is:
y = 180 + 120x .............. 2
First warehouse having 1.2times
y = ( 210 + 90x ) × 1.2
y = 252 +108x ................... 3
Now, equate 2 and 3
252 + 108x = 180 + 120x
252 - 180 = 120x - 108x
72 = 12x
x = 72/12
x = 6
Now, substitute 6 into equation 1 and 2
From 1 , y = 210 + 90x
y = 210 + 90 ×6
y = 210 + 540
y = 750
From equation 2
y = 180 + 120x
y = 180 + 120×6
y = 180 + 720
y = 900
Recall that equation 1 was to be 1.2times
From the answer in equation 1
y =750
y = 750 × 1.2
y = 900
Hence, the answer is correct.
Answer:
Prospective study
Step-by-step explanation:
Also known as a cohort study, the type of study that follows a certain group of individuals over time to reach conclusions about the data gathered at a future date is called a prospective study. Since the aim of this study is to see who develops cancer in the future, this is a clear example of a prospective study.
4(x + 2) - 1/2x = 22
4x + 8 - 1/2x = 22
3.5x + 8 = 22
-8 -8
3.5x = 14
/ 3.5 /3.5
x = 4
