I'm not sure how to do the math for this
Answers
Answer:
156
Step-by-step explanation:
3 ml of compound A used for every 4 ml of compound B in total it's 7 ml
To calculate how many ml of A used in a 364 ml drug we can divide 364 by 7
364 ÷ 7 = 52 which means there are 52, 7 ml in the 364
since 7 ml drug contains 3 ml conpound A there is
52 × 3 = 156 of compound A in the 364 ml drug

Let s represent the time Mo-Qui spent studying Spanish and h represent the time Mo-Qui spent studying History.
s = h + 30
s > 2 hrs. 15 mins. (he isn't done yet)
Substitute
2 hrs. 15 mins. = h + 30 mins.
Subtract 30 mins. from both sides
1 hr. 45 mins. = h
However, s > 2 hrs. 15 mins., so h must be more than 1 hr. and 45 mins.
h > 1 hr. 45 mins.

Hanna walks a total of 3 1/6 miles before and after school.
To find how many miles Hanna walks before and after school, we can add the distances she walks to school and to work.
Distance to school = 1 2/3 miles
Distance to work = 1 1/2 miles
To find the total distance Hanna walks before and after school, add the two distances:
Total distance = 1 2/3 + 1 1/2
To add these fractions, we need to convert them to have a common denominator, which is 6:
1 2/3 = (3/3 + 2/3) = 5/3
1 1/2 = (3/2)
Now, we can add the fractions:
Total distance = 5/3 + 3/2
To add these fractions, we need to have a common denominator, which is 6:
Total distance = (5/3) * (2/2) + (3/2) * (3/3)
Total distance = 10/6 + 9/6
Now, add the fractions:
Total distance = 19/6
We can simplify this fraction:
Total distance = 3 1/6 miles
So, Hanna walks a total of 3 1/6 miles before and after school.

Answer:
MAD or also called as median absolute deviation is equal to zero. This means that there is no deviation and all the values are the same.
When a given number series is sorted in ascending order, the median is the middle number and that is zero.
MAD is a way to describe variation in a data set.
When a teacher gets MAD of zero, this means all the values are zero.
