Answer:
The answer to your question is:
Step-by-step explanation:
11.-
Data
red beads = 8.5 x 10³
white beads = 1.7 x 10³
Number = 8.5 x 10³ / 1.7 x 10³ = 5 times
12.-
Data
1.8 x 10 ⁴ steps each day
Number of steps in 180 days
1.8 x 10⁴ steps ------------------- 1 day
x ------------------- 180 days
x = (180 x 1.8 x 10⁴ ) / 1
x = 3240000 steps
x = 3.24 x 10 ⁶ steps
Reasoning
Data
1.2 x 10² paper plates
5.04 x 10³ napkins
a) The exponent will be negative because the power of number of paper plates is lower than the power of number of napkins.
relation = 1.2 x 10² / 5.04 x 10³
= 0.024
= 2.4 x 10 ⁻²
b) relation = 5.04 x 10³ / 1.2 x 10²
= 42
= 4.2 x 10¹
The power is positive because the number of napkins is greater than the number of paper plates.
