Answer:
153.1ml
Step-by-step explanation:
We have 12.5ml of acid in the solution.
If we want this to be 3% then we can divide this value by 3 and times by 100 to get the total value.
416.6ml total solution amount
415.6-12.5-250=153.1
The length of other base of trapezoid is 10 miles
Step-by-step explanation:
The formula for area of trapezoid is:

We know that
A = 42 square miles
b_1 = 4 miles
h = 6 miles
Putting the values

The mean of a set of numbers is the average of the set. To find the mean we must add all the numbers in the set together and divide the sum by how many numbers there are in the set.
95 + 78 + 84 + 86 + 89 + 64 = 496
499 / 6 = 82.67
The mean is 82.67.
The mode of a set of numbers is a number that shows up the most in the set. All the numbers in this set appear once, so, there is no mode.
The median of a set of numbers is the number that is in the very middle of the set. Since the middle has two numbers in it we will find the mean of the two of them.
84 + 86 = 170
170 / 2 = 85
85 is median.
To find the range we need to subtract the smallest number by the largest number.
95 - 64 = 31
31 is the range.
I hope this helps. :)
