The option A is the right answer
let 'x' represent the number of all the passes for the year
350 passes = 70% of all the passes
350 passes = 70% of x
0.70x = 350
by solving we find:
x = 500 passes
Answer:
30 days(To the nearest tenth of a day)
Step-by-step explanation:
In this question, we are asked to give the number of days that a baby whale had grew to a size given the rate at which it grows per day.
We have been told that after the first day, it started growing to a point of 47.075 inch at a rate of 1.5 inch a day.
The number of days taken for this growth can be calculated by dividing the present size by the daily growth rate.
Mathematically, that is 47.075/15 = 31.38333
Now, we are told to convert this to the nearest tenth of a day. The value here should thus be 30.
