55% of 125 is 68.75 because 55/100 or 0.55 times 125 equals 68.75.
Part 1) we have that
volume smaller solid=512 cm³
volume larger solid=2197 cm³
we know that
volume larger solid=[scale factor]³*volume smaller solid
scale factor=∛[volume larger solid/volume smaller solid]
scale factor=∛[2197/512]-----> scale factor=1.625
Part 2)
the ratio of the surface areas is equal to [scale factor]²
1.625²-------> 2.64
Part 3)
surface area smaller solid=960 cm²
then
surface area larger solid=scale factor²*surface area smaller solid
surface area larger solid=[1.625]²*960-----> 2535 cm²
surface area larger solid is 2535 cm²
The numbers are 11 and 6.
Answer:
241m/5.4km
Step-by-step explanation:
Answer:
C. 2x^4; E. -5x
Step-by-step explanation:
P(x) = x^3 − x − 2 and Q(x) = x^2 + 2x + 1
P(x) * Q(x) = (x^3 − x − 2)(x^2 + 2x + 1) =
= x^5 + 2x^4 + x^3 - x^3 - 2x^2 - x - 2x^2 - 4x - 2
= x^5 + 2x^4 - 4x^2 - 5x - 2
Answer: C. 2x^4; E. -5x
