Answer:
- 4 2/3 pounds of cereal Y; none of cereal X
- $37.33 is the minimum cost
Step-by-step explanation:
The quantity of vitamin A in the food is ...
10X +30Y ≥ 140
and vitamin B ...
20X +50Y ≥ 140
The cost, which we want to minimize is ...
12X +8Y
__
A graph shows that any diet meeting the requirement for vitamin A will also meet the requirement for vitamin B. Vitamin A in the form of cereal X costs ...
$12/(10 mg) = $1.20/mg
In the form of cereal Y, it costs ...
$8/(30 mg) ≈ $0.27/mg
So, cost is minimized by satisfying the vitamin requirements using cereal Y exclusively. That cost is $37.33 for 4 2/3 pounds of cereal Y only.

Answer:
Just break down the answer.
Step-by-step explanation
(2•2)•(2•2•2•2)•(2•2•2)
You are just see how much you have in each exponent. The number you have in exponents is main number you put out.
First step: partition the number you want to square root into a block of 2 digits, starting from the last digit (first diagram)
Second step: As our number is a five-digits, we ends up with 2 28 01. Pick a number that could be squared to get the first partition, 2. This number is 1, since 1×1=1
Third step: Write 1 on the top and on the side, as shown in the second graph
Fourth step: Double the number on the side, which is 1+1=2 and use this number as the first digit for the next multiplier. Meanwhile, subtract 1 from 2 inside the root sign to get 1, then pull the other two digits, 28
Fifth step: We need a value in the boxes that when we multiply together will give a number less than 128. We choose 5 as 25×5=125
Sixth step: Subtract 125 from 128 to give 3, and as the same concept with long division, bring down the 0 and the 1. So we have 301
Seventh step: Add 5 to the multiplier on the left, so 20+5=30, which we will use on the side as the hundred and ten digits.
Final step: Find a number to fit in the boxes. We choose 1 since 301×1=301
And hence the square root of 228801 is 151
