<span>side lengths are decreased to 20% of their original size - it means that the new side is 80% of a. Let's call it side b.
b=.8a
V = (.8a)^3 = .512a^3 </span>
She was unable to salvage 4.8% of the total number of samples. If she was able to salvage 12 of the 24 improperly stored samples, then she was unable to salvage 12 of them. Divide the number that was not salvaged (12) by the total number of samples (250), then multiply by 100 to get the percentage.
Answer:
this makes no sense.
Step-by-step explanation:
Answer: 2(−5x^2
+9)(5x^2
+9)
Step-by-step explanation:
Given: 162-50x^4
Factor out 2: 2(81-25x^4)
Rewrite: 2(9^2-(5x^2)^2)
Use difference of squares: 2(9-5x^2)(9+5x^2)
Reorder (if you need to) 2(-5x^2+9)(5x^2+9)
