Answer:
The scale factor is 0.5
Step-by-step explanation:
Divide.
2/1=2
4/2=2
4/2=2
8/4=2
2/1=2
5/1.25=2
Now then, since this is a shrinking factor, divide 1 by the common outcome from the last section (2) to get 0.5
Answer:
656.4671128 nanometer
Step-by-step explanation:
1 nano meter = 10 ^-9 meter
Now given 6.564671128 × 10^ -7 meters
so in nano meter ,
= 656.4671128 × 10^-9 meter
= 656.4671128 nanometer Answer
Answer:
60 in
Step-by-step explanation:
Area = length x width
Area is constant at 1440 in^2
For first rectangle: W1 and L1
For second rectangle: W2 and L2
W1 = 32 in
W2 = W1 - 8 in = 24 in
1440 in^2 = L1 x 32 in = L2 x 24 in
L1 = 45 in
L2 = 60 in
