Answer:
440 pounds
Step-by-step explanation:
The ratio of the total weight to the weight of apples is ...
(4 + 3 + 4) : 4 = 11/4
So, the total weight will be ...
total weight = (total weight)/(apple weight) × (apple weight) = (11/4)×(160 lb)
total weight = 440 lb

<em>Comment on the problem</em>
The problem doesn't say what the ratio is. We have to assume it is the ratio of weights. (It could be the ratios by volume, sugar content, cost, or any of a number of other factors.)
Answer:
Term to add is (3/8)^2 = 9/64
Step-by-step explanation:
Here, we want to know the value that must be added to make the equation a perfect square.
x^2 - 3/4x = 5
x^2 -3/4x -(3/8)^2+ (3/8)^2 = 5
x^2 -3/4x + (3/8)^2 = 5 + (3/8)^2
= (x-3/8)^2 = 5 + (3/8)^2
So the term to add is (3/8)^2 = 9/64
-9x(5 - 2x) Distribute/multiply 9x into (5 - 2x)
(-9x)5 - (-9x)2x
-45x - (-18x²) 2 negative signs cancel each other out and become +
-45x + 18x² Your answer is A ( the first option)
