Answer:
her work is correct but there is one solution rather than no solution
Step-by-step explanation:
- hmmmmm but the equation is better t there but I think this should be it
- Assuming the equation was given
Answer:
Step-by-step explanation:
let X be the quantity of 100% acid
let Y be the quantity of 10% acid
X + Y = 90
Y = 90 - X
X(100) + Y(10) = 90(81)
X(100) + (90 - X)(10) = 90(81)
100X + 900 - 10X = 7290
90X = 6390
X = 71 L
First, two numbers are 94- I'm stuck on the remainder, let me know when you get it.
Answe t = bh b = t h the number of bikes produced each hour is the constant of proportionality. total bikes = bikes per hour( number of hours) → t = bh total bikes number of hours = bikes per hour → b = t h y = kx, where k is the constant of proportionality → t = bh; thus, b is the constant of proportionality.
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
If you arrange a statistics in order from least to greatest, the middle number is the median.
If there is even number of numbers in a list, let it be n numbers, then we take the average of n/2th and n/2 + 1 th terms.
Here, all of them have 6 numbers, so 6/2 = 3 and 4th, we take average of 3rd and 4th number to find the median.
Since they are arrange in order we check each:
Jon = average of 6 and 7, (6+7)/2 = 6.5
Leroy = average of 6 and 8, (6+8)/2 = 7
Simon = average of 5 and 6, (5+6)/2 = 5.5
Leroy's median is the greatest (7).
