114 = 19y
This is true because they are vertical angles. Now, let's divide both sides by 19
6 = y
Add all of the numbers 50+30+100=180 and you have to find 180s multiples which are <span>1,2,3,4,5,6,9,10,12,15,18,20,30,36,45,60,90,180. So you can do and of those numbers and just divide them by 180 to find the number of items that would be inside the box. For example, 180 divided by 3 boxes would be 60 items in each box.</span>
Answer:
3 ounces of medication to be added to get 20%solution of medication
Step-by-step explanation:
To find:
The amount of medication to be added to 12 ounces of water to get a 20% solution
Let the amount of medication to be added =x
So total amount of mixture = amount of water + amount of medication
= 12+x
% medication = (amount of medication÷total amount of the mixture)× 100
Therefore
% medication =( x÷12+x)×100
20 =( x÷12+x)×100
X 100
20(12+x) =100x
240+20x =100x
100x-20x =240
80x =240
x =240÷80
x=3
so 3 ounces of medication to be added to get 20%solution of medication
Answer:
<h2>1 </h2>
Step-by-step explanation:
A data arranged in descending order is a data arranged from the biggest to the smallest. The medisn of the data sets is the value at the middle of the dataset after rearrangment.
For the dataset {8, x, 4,1}, the median will be x and 4. Since we have two median values, we will take their average as shown
Median(1) =
... 1
Simialrly for dataset {9, y, 5,2}, the median will be y and 5.
Median(2) =
...2
Since the medians of the two given datasets are equal, we will equate equation 1 and 2 and calculate for y-x as shown;


Therefore y-x = -1
(y-x)² = (-1)²
= 1
