Answer:
4
Step-by-step explanation:
when all the lengths are multiplied by x (length scale factor), the volumes are multiplied by x³ (volume scale factor).
∴ when volume scale factor = 8
the length scale factor = ∛8 = 2
while When all the lengths are multiplied by x (length scale factor), the areas are multiplied by x² (surface area scale factor).
∴ when the length scale factor = 2
the surface area scale factor = 2² = 4
Answer:
1.9
Step-by-step explanation:
Gabrielle uses 7.6 pints of blue and white paint to paint her bedroom
1/4 of the paint is blue paint
Therefore the amount of white paint she used to paint her bedroom can he calculated as follows
= 1/4
= 0.25×100
= 25%
25/100×7.6
= 2.5 × 7.6
= 1.9
Hence 1.9 pints of white paint was used to paint the room
122/4=30.5
30x3=91.5
Piece 1= 30.5in.
Piece 2= 91.5in
