Step 1:
meassure angle for group 0-19 that lives in Adley
Step 2:
divide this angle by 360. this is proportional of that group in total number of people in Adley
Repeat these steps for group 0-19 in Bridford.
Final solution can be found by multiplying the two solutions of step 2.
Answer:
- 1 bag
- 172 pens, 63 pencils, 27 erasers
Step-by-step explanation:
The numbers 27 and 63 have a greatest common factor of 9, but that is not a factor of 172. The greatest common factor of all three numbers is 1, so ...
(i) the largest number of gift bags that can be packed is 1
(ii) in each bag will be 172 pens, 63 pencils, and 27 erasers.
We must mix 240 liters of the 51 % solution and 10 liters of the 26 % solutions to produce 250 liters of 50 % solution.
<h3>How to prepare a solution by using weighted averages</h3>
Herein we have to prepare a solution with fertilizers by mixing two <em>different</em> solutions. The amount needed of the 51 % solution can be found by weighted averages:
(50/100) · (250 L) = (51/100) · x + (26/100) · (250 - x)
50 · 250 = 51 · x + 26 · 250 - 26 · x
24 · 250 = 25 · x
x = 240
We must mix 240 liters of the 51 % solution and 10 liters of the 26 % solutions to produce 250 liters of 50 % solution.
