Answer:
Step-by-step explanation:
Because we are looking for the scale factor of the model to the bridge (model first), the scale factor will be less than one.
Each fraction () can be simplified to . Therefore, the scale factor of the model to the bridge is .
Answer:
3p^3 + qp^2 - pq^2 + 3q^3
Step-by-step explanation:
(p²-pq + q²) ( 3p+ 3q)
3p^3 + 3qp^2 - 3qp^2 - 3pq^2 + 3pq^2 + 3q^3
3p^3 + qp^2 - pq^2 + 3q^3
Answer:
D 25%
Step-by-step explanation:
Add all of the grams together = 120 grams
cheese weight =30 grams
divide 30 by total 120 = .25 or 25%
9514 1404 393
Answer:
21 1/3 grams
Step-by-step explanation:
The mass is the product of the volume and the density. The volume of a cube is the cube of its edge dimension.
M = Vρ
M = (4 cm)³×(3 g/cm³) = 64/3 g
The mass of the cube is 64/3 = 21 1/3 grams.
